Acute Coronary Syndromes

Use of continuous positive-airway pressure devices for at least 4 hours a day was associated with a reduced risk of major adverse cardiac and cerebrovascular events in adults with cardiovascular disease and obstructive sleep apnea, based on data from more than 4,000 individuals.

Obstructive sleep apnea (OSA) is associated with an increased risk of cardiovascular diseases, but the association between management of OSA with a continuous positive-airway pressure device (CPAP) and major adverse cardiac or cerebrovascular events (MACCEs) remains unclear, wrote Manuel Sánchez-de-la-Torre, PhD, of the University of Lleida, Spain, and colleagues.

In a meta-analysis published in JAMA, the researchers reviewed data from 4,186 individuals with a mean age of 61.2 years; 82.1% were men. The study population included 2,097 patients who used CPAP and 2,089 who did not. The mean apnea-hypopnea index (AHI) was 31.2 events per hour, and OSA was defined as an oxygen desaturation index of 12 events or more per hour or an AHI of 15 events or more per hour. The composite primary outcome included the first MACCE, or death from cardiovascular causes, myocardial infarction, stroke, revascularization procedure, hospital admission for heart failure, hospital admission for unstable angina, or hospital admission for transient ischemic attack. Each of these components was a secondary endpoint.

Overall, the primary outcome of MACCE was similar for CPAP and non-CPAP using patients (hazard ratio, 1.01) with a total of 349 MACCE events in the CPAP group and 342 in the non-CPAP group. The mean adherence to CPAP was 3.1 hours per day. A total of 38.5% of patients in the CPAP group met the criteria for good adherence, defined as a mean of 4 or more hours per day.

However, as defined, good adherence to CPAP significantly reduced the risk of MACCE, compared with no CPAP use (HR, 0.69), and a sensitivity analysis showed a significant risk reduction, compared with patients who did not meet the criteria for good adherence (HR, 0.55; P = .005).

“Adherence to treatment is complex to determine and there are other potential factors that could affect patient adherence, such as health education, motivation, attitude, self-efficacy, psychosocial factors, and other health care system–related features,” the researchers wrote in their discussion.

The findings were limited by several factors including the evaluation only of CPAP as a treatment for OSA, and the inability to assess separate components of the composite endpoint, the researchers noted. Other limitations included the relatively small number of female patients, reliance mainly on at-home sleep apnea tests, and the potential for selection bias, they said.

However, the results suggest that CPAP adherence is important to prevention of secondary cardiovascular outcomes in OSA patients, and that implementation of specific and personalized strategies to improve adherence to treatment should be a clinical priority, they concluded.

The study was funded by the Instituto de Salud Carlos III, the European Union and FEDER, IRBLleida–Fundació Dr Pifarré, SEPAR, ResMed Ltd. (Australia), Associació Lleidatana de Respiratori, and CIBERES. Dr Sánchez-de-la-Torre also disclosed financial support from a Ramón y Cajal grant.

The American Heart Association has released a focused update on managing patients with cardiac arrest or life-threatening toxicity due to poisoning.

The update reflects treatment advances and new knowledge, including the use of venoarterial extracorporeal membrane oxygenation (VA-ECMO) for patients whose condition is refractory to poison antidotes and other therapies.

The new guidelines are designed primarily for North American health care professionals who treat adults and children who are critically ill because of poisoning, including intentional and unintentional drug overdose, chemical exposure, and drug-drug interactions, the authors note.

Published online in Circulation, the update was endorsed by the American Academy of Pediatrics.
 

‘Nearly miraculous’

“It’s been 13 years since the poisoning treatment guidelines had a comprehensive update,” lead author Eric J. Lavonas, MD, professor of emergency medicine at Denver Health and the Rocky Mountain Poison and Drug Center, Colo., told this news organization. “In that time, we’ve learned a lot about how to best use antidotes and other treatments to save the most critically poisoned patients.”

Highlighting a few key points from the update, he said, “For those rare situations when antidotes aren’t enough, the new guidelines include the use of heart-lung machines (VA-ECMO) for patients with beta-blocker, calcium channel blocker, or sodium channel blocker poisoning causing cardiogenic shock.”

Furthermore, he said, “High-dose insulin treatment for patients with beta-blocker and calcium channel blocker poisoning [also recommended in the update] has really become mainstream. The doses are up to 10 times higher than the amount used to treat diabetic emergencies.

“Some excellent science has shown that giving IV lipid emulsion can save the life of someone with an accidental overdose of local anesthetic medications, particularly bupivacaine,” he added. “The result is sometimes nearly miraculous.

“But when this treatment is extended to poisoning from other medications, it often doesn’t work as well, and in some situations may make things worse,” he said. “The issue may be that giving lipids increases absorption of drug from the stomach and intestines, which can be dangerous when the patient took an overdose of pills.”
 

Low level of evidence

The guidelines were compiled by the Critical Poisoning Writing Group, which includes experts from emergency medicine, pediatrics, medical toxicology, pharmacology, critical care, emergency medical services, education, research, and nursing. Group members were appointed by the AHA Emergency Cardiovascular Care Science Subcommittee and were approved by the AHA Manuscript Oversight Committee.

First and foremost, the group recommends timely consultation with a medical toxicologist, a clinical toxicologist, or a regional poison center to facilitate rapid, effective therapy, because treatment of cardiac arrest and toxicity from poisoning often requires treatments that most clinicians don’t use frequently.

Other key points include the following:

• Naloxone administration may reverse respiratory arrest due to opioid overdose, preventing progression to cardiac arrest.
• Give high-dose insulin therapy early in the treatment of patients with beta-blocker and calcium channel blocker poisoning, Dr. Lavonas noted.
• Standard advanced life support plus sodium bicarbonate is appropriate for life-threatening dysrhythmias caused by cocaine or other sodium channel blockers.
• If cyanide poisoning is suspected, clinicians should not wait for confirmatory testing; treatment should begin immediately with hydroxocobalamin (preferred) or sodium nitrite plus sodium thiosulfate.
• Digoxin-specific immune antibody fragments can reverse life-threatening dysrhythmias from digoxin poisoning.
• Use of 20% intravenous lipid emulsion can be efficacious in the resuscitation of life-threatening local anesthetic toxicity, especially from bupivacaine, Dr. Lavonas indicated.
• Sedation is recommended for patients with severe agitation from sympathomimetic poisoning to manage hyperthermia and acidosis, prevent rhabdomyolysis and injury, and allow evaluation for other life-threatening conditions.
• Although flumazenil reverses central nervous system and respiratory depression from benzodiazepine poisoning, risks and contraindications, provided in the guidelines, limit its use.
• VA-ECMO can be lifesaving for patients with cardiogenic shock or dysrhythmias that are refractory to other treatments.

“Unfortunately, despite improvements in the design and funding support for resuscitation research, the overall certainty of the evidence base for resuscitation science and management of critical poisoning is low,” the group acknowledges.

Of the 73 guideline recommendations, only 2 are supported by level A evidence; 3 are supported by level B-randomized evidence, 12 by level B-nonrandomized evidence, and the rest by level C evidence.

“Accordingly, the strength of recommendations is weaker than optimal,” they write. “Clinical trials in resuscitation and the management of critical poisoning are sorely needed.”
 

‘Don’t go it alone!’

“Most critical poisonings are pretty uncommon, and each patient is different,” Dr. Lavonas said. “Even in the emergency department or ICU, most physicians will treat a patient who is critically ill with any given poison less than once a year. The antidotes and medication doses needed to effectively treat these patients are often very different than everyday medical practice.

“Don’t try to go it alone!” he urges. “Poisoning cases are complex, and the treatments work best when they are implemented quickly and assertively. A toxicologist can help sort through complex situations and get effective treatment started without delay.”

Every certified poison center has a medical toxicologist or clinical toxicologist on call 24/7 to give advice to physicians and hospitals about patients who are critically ill after being poisoned, he added. “Everyone in the U.S. has access to a poison center by calling one number: 1-800-222-1222.”

Dr. Lavonas has disclosed no relevant financial relationships.

Moving from one residence to another after an acute myocardial infarction (AMI) significantly increases the risk for death or transition to a long-term care facility as an end-of-life measure, data suggest.

In a prospective study that followed more than 3,000 patients with AMI over 2 decades, each residential move was associated with a 12% higher rate of death.

“This study determined that residential mobility was more important than any other social factor that we studied,” investigator David Alter, MD, PhD, chair of cardiovascular and metabolic research at the University Health Network–Toronto Rehabilitation Institute and associate professor of medicine at the University of Toronto, said in an interview.

The results were published online in the Canadian Journal of Cardiology.
 

Moving and mortality

“There’s been very little work, surprisingly, on what happens when individuals move from community to community,” said Dr. Alter. “It is that movement from community to community that is a factor within the social context that needs to be explored better. To the best of our knowledge, up until our study, it has been studied very briefly in the literature.”

The prospective cohort study sample included 3,369 patients who had an AMI between Dec. 1, 1999, and March 30, 2023. The investigators followed participants until death or the last available follow-up date of March 30, 2020. They defined a residential move as a relocation from one postal code region to another.

The investigators drew data from multiple sources, including the prospective, observational Socio-Economic Status and Acute Myocardial Infarction study, which encompassed more than 35,000 patient life-years following hospitalization for a first heart attack in Ontario. Mortality data were collected from the Ontario Registered Persons Data Base. Other sources included Statistics Canada for information on neighborhood income, the Canadian Institutes for Health Information for patients’ clinical factors and comorbidities, and the Ontario Health Insurance Plan (OHIP) database for physician visits. Information on long-term care admissions came from the Continuous Care Reporting System-Long Term Care, OHIP, and the Ontario Drugs Benefit databases, the latter of which also provided information on medication prescriptions for individuals aged 65 years and older.

Patients’ ages ranged from 19 to 101 years (median age, 65 years). About 69% of patients were men. Of the study population, 1,828 patients (54.3%) had at least one residential move during the study period. Approximately 87% died in the community or moved from home into a long-term care facility as an end-of-life destination. Overall, 84.8% of patients who were admitted to long-term care facilities died.

The study also tracked the socioeconomic status of persons living in the postal code regions from and to which patients moved. About 32% of patients moved to a neighborhood with a lower socioeconomic status, and 30.5% moved to an area with a higher socioeconomic status.

Each residential move was associated with a 12% higher rate of death and a 26% higher rate of long-term institutionalization for end-of-life care. In unadjusted analyses, the rate of death was almost double for those who moved more frequently: 44.3% for those who moved two or more times versus 24.8% for those who moved once in 10 years.

Accounting for a multitude of variables, such as the socioeconomic status of areas that patients moved between, is a strength of the study, said Dr. Alter. But the study lacked information about why people moved.

“Where this study has a huge amount of strength is that it was designed specifically to really understand a patient’s clinical and psychosocial profile at the start of their journey, their first AMI. But the fact that we took it from heart attack onward is also a strength because it characterizes and anchors a clinical context in which we were following patients out,” said Dr. Alter.
 

‘An important marker’

In a comment, Paul Oh, MD, medical director of the cardiovascular disease prevention and rehabilitation program at University Health Network, said: “This is a very well-designed study and analysis from a cohort that has provided important insights about the role of socioeconomic factors and long-term outcomes post MI over many years.” Dr. Oh did not participate in the study.

“A few covariates that could impact on outcomes, like institutionalization, were not available to include in adjusted analyses – e.g., functional status, frailty, mild cognitive changes, and availability of social supports in the home,” he said.

The findings add another variable that cardiologists who care for post-MI patients need to be aware of, Dr. Oh added. “Clinicians need better awareness that the need to change residence is an important marker of changing health status and may portend end-of-life events in the near future. The need to change residence can signal an important change in physical, cognitive, and social circumstances that needs to be further explored during clinical encounters, with the goal of identifying and addressing any potentially reversible issues and identifying additional supports that may help that individual continue to live independently in their own home.”

The study was supported by ICES, which receives funding from the Ontario Ministry of Health. The investigators disclosed no relevant financial relationships. Dr. Oh serves on research boards for Lilly and Novartis and receives research funding from Apple.

In a comment, Paul Oh, MD, medical director of the cardiovascular disease prevention and rehabilitation program at University Health Network, said: “This is a very well-designed study and analysis from a cohort that has provided important insights about the role of socioeconomic factors and long-term outcomes post MI over many years.” Dr. Oh did not participate in the study.

“A few covariates that could impact on outcomes, like institutionalization, were not available to include in adjusted analyses – e.g., functional status, frailty, mild cognitive changes, and availability of social supports in the home,” he said.

The findings add another variable that cardiologists who care for post-MI patients need to be aware of, Dr. Oh added. “Clinicians need better awareness that the need to change residence is an important marker of changing health status and may portend end-of-life events in the near future. The need to change residence can signal an important change in physical, cognitive, and social circumstances that needs to be further explored during clinical encounters, with the goal of identifying and addressing any potentially reversible issues and identifying additional supports that may help that individual continue to live independently in their own home.”

The study was supported by ICES, which receives funding from the Ontario Ministry of Health. The investigators disclosed no relevant financial relationships. Dr. Oh serves on research boards for Lilly and Novartis and receives research funding from Apple.

Moving from one residence to another after an acute myocardial infarction (AMI) significantly increases the risk for death or transition to a long-term care facility as an end-of-life measure, data suggest.

In a prospective study that followed more than 3,000 patients with AMI over 2 decades, each residential move was associated with a 12% higher rate of death.

“This study determined that residential mobility was more important than any other social factor that we studied,” investigator David Alter, MD, PhD, chair of cardiovascular and metabolic research at the University Health Network–Toronto Rehabilitation Institute and associate professor of medicine at the University of Toronto, said in an interview.

The results were published online in the Canadian Journal of Cardiology.
 

Moving and mortality

“There’s been very little work, surprisingly, on what happens when individuals move from community to community,” said Dr. Alter. “It is that movement from community to community that is a factor within the social context that needs to be explored better. To the best of our knowledge, up until our study, it has been studied very briefly in the literature.”

The prospective cohort study sample included 3,369 patients who had an AMI between Dec. 1, 1999, and March 30, 2023. The investigators followed participants until death or the last available follow-up date of March 30, 2020. They defined a residential move as a relocation from one postal code region to another.

The investigators drew data from multiple sources, including the prospective, observational Socio-Economic Status and Acute Myocardial Infarction study, which encompassed more than 35,000 patient life-years following hospitalization for a first heart attack in Ontario. Mortality data were collected from the Ontario Registered Persons Data Base. Other sources included Statistics Canada for information on neighborhood income, the Canadian Institutes for Health Information for patients’ clinical factors and comorbidities, and the Ontario Health Insurance Plan (OHIP) database for physician visits. Information on long-term care admissions came from the Continuous Care Reporting System-Long Term Care, OHIP, and the Ontario Drugs Benefit databases, the latter of which also provided information on medication prescriptions for individuals aged 65 years and older.

Patients’ ages ranged from 19 to 101 years (median age, 65 years). About 69% of patients were men. Of the study population, 1,828 patients (54.3%) had at least one residential move during the study period. Approximately 87% died in the community or moved from home into a long-term care facility as an end-of-life destination. Overall, 84.8% of patients who were admitted to long-term care facilities died.

The study also tracked the socioeconomic status of persons living in the postal code regions from and to which patients moved. About 32% of patients moved to a neighborhood with a lower socioeconomic status, and 30.5% moved to an area with a higher socioeconomic status.

Each residential move was associated with a 12% higher rate of death and a 26% higher rate of long-term institutionalization for end-of-life care. In unadjusted analyses, the rate of death was almost double for those who moved more frequently: 44.3% for those who moved two or more times versus 24.8% for those who moved once in 10 years.

Accounting for a multitude of variables, such as the socioeconomic status of areas that patients moved between, is a strength of the study, said Dr. Alter. But the study lacked information about why people moved.

“Where this study has a huge amount of strength is that it was designed specifically to really understand a patient’s clinical and psychosocial profile at the start of their journey, their first AMI. But the fact that we took it from heart attack onward is also a strength because it characterizes and anchors a clinical context in which we were following patients out,” said Dr. Alter.

TOPLINE:

Women who use cocaine, cannabis, or other substances during pregnancy have increased risks of acute cardiovascular (CV) events while in the hospital for delivery, including more than double the risk of maternal mortality, a new study shows.

METHODOLOGY:

• Using the National Inpatient Sample database to identify hospital deliveries between 2004 and 2018 and diagnostic codes to identify maternal substance use, researchers compared 955,531 pregnancies with accompanying substance use – the most common substances being cannabis and opioids, followed by stimulants – to over 60 million pregnancies in which there was no substance use.
• The primary outcome was any CV event, including acute myocardial infarction, stroke, arrhythmia, endocarditis, any acute cardiomyopathy or heart failure, or cardiac arrest; other outcomes included maternal mortality and major adverse cardiac events (MACE).

TAKEAWAY:

• Deliveries complicated by substance use increased from 1,126 per 100,000 deliveries in 2004 to 1,547 per 100,000 in 2018, peaking at 2,187 per 100,000 in 2014.
• After the researchers controlled for patient demographics and CVD risk factors, results showed that pregnant women who used any substance (cannabis, opioids, methamphetamine, alcohol, tobacco, or cocaine) were more likely to experience a CVD event (adjusted odds ratio [aOR], 1.61; 95% confidence interval [CI], 1.53-1.70; P < .001), MACE (aOR, 1.53; 95% CI, 1.46-1.61; P < .001), or maternal mortality (aOR, 2.65; 95% CI, 2.15-3.25; P < .001) during hospitalization for delivery.
• Those using amphetamine/methamphetamine had ninefold higher odds of cardiomyopathy or heart failure and more than sevenfold higher odds of cardiac arrest.

IN PRACTICE:

“For the wellbeing of pregnant women and their children, substance use needs to be considered an independent risk factor for CV events in pregnancy,” the authors wrote. They called for prenatal assessments by a multidisciplinary cardio-obstetrics team to try to decrease cardiac complications.

In an accompanying editorial by Abha Khandelwal, MD, department of medicine, Stanford (Calif.) University, and others, the authors said the findings “highlight the critical support required during pregnancy and postpartum” for substance users, which should include comprehensive medical care and social services as well as access to addiction medicine and treatment of co-occurring mental health disorders.

SOURCE:

The study was carried out by Kari Evans, MD, division of maternal fetal medicine, department of obstetrics and gynecology, University of Arizona, Phoenix. It was published online in the Journal of the American College of Cardiology: Advances.

LIMITATIONS:

Use of administrative databases may have resulted in underreporting of diagnoses. The researchers could not assess the association of dose, duration, method, or timing of use for any substance with CV events. They also could not examine the effect of vaping on maternal CV events or differentiate hospitalizations for delivery that were complicated by CV events from hospitalizations for CV events that prompted delivery. The data did not reflect the postpartum period, during which a high rate of adverse CV events occurs.

DISCLOSURES:

The authors and editorial writers have no relevant conflicts of interest.

Recorded Aug. 26, 2023. This transcript has been edited for clarity.

Robert A. Harrington, MD: I’m here with my good friend, Manesh Patel, from Duke University. We’re at the European Society of Cardiology (ESC) congress in Amsterdam, and I pulled Manesh into the studio for a conversation about something that’s really topical right now: sudden cardiac death in athletes.

What I hope to do [in this interview] is really pick Manesh’s brain on how we are thinking about this. Are we going to think about treatment issues? Are we going to think about prevention issues? Are we thinking about screening? We’ll try to make it practical.

Dr. Manesh Patel is chief of cardiovascular medicine at Duke University and also the director of the Duke Heart Center. Manesh, thanks for joining me here.
 

Bronny James and Damar Hamlin

Manesh R. Patel, MD: Excited to be here, Bob. Always.

Harrington: [Recently,] a news article comes out about the cause of Bronny James’ sudden cardiac death. Let me put this into a bigger societal context.

Last winter, Damar Hamlin, from the Buffalo Bills, suffered a traumatic injury on the field, and with that, had cardiac arrest. He’s back playing football – great to see. You and I are involved with the American Heart Association. He’s been very supportive of our efforts around things like CPR. He’s been terrific. It’s great to see him playing.

We know a little less about Bronny James. The news articles say the cause is both functional and anatomical, and it seems to be congenital, but we don’t have any details beyond this. Let’s not focus on the people; let’s focus on the topic.

Patel: I’m excited that we’re having the conversation. First and foremost, we’re excited that, with what we’ve seen on a national stage, these two individuals are doing well. They survived sudden cardiac death, which is a testament to all the things that we’ll talk about.

There are many important questions, like, is this increasing? Is this something we can prevent? And what are those things that might be happening to athletes?

Harrington: Can we predict it?

Patel: Right. I think the idea of sudden cardiac death in athletes is really a critical one for us to think about because it does concern participation and what we think about that. There are many experts who’ve been studying this for years that I now get to work with.

Harrington: Tell us a little bit about the kind of things you’ve been doing in this area.

Patel: Even before these events in the COVID era, we were wondering about athletes getting myocarditis, just in general, what do we know about that? People like Aaron Baggish, Kim Harmon, Jonathan Drezner, and others have been studying this.

Harrington: You and I did a show on athletes and COVID-19.

Patel: With the American Heart Association (AHA), the Cornell Foundation, and others, we started the Outcomes Registry for Cardiac Conditions in Athletes (ORCCA). This registry is across the United States, and athletes can sign up.

Harrington: Is it voluntary? Do the schools sign them up?

Patel: The athletes sign up. Team trainers and doctors talk to the athletes. We don’t really know the risks of some of these conditions. There’s a lot of gray area – people with certain conditions that were really interesting; aortas that are dilated in tall people.

Harrington: Long QT.

Patel: Long QT. There are certainly things that we know we should be intervening on and others where participation is a question. All of these we are trying to longitudinally put into the registry and follow them over time.

The second thing is understanding from the last Bethesda Conference that we want shared decision-making. There are going to be conditions where you say, “Look, I think your risk is high. You’ve a family history of sudden cardiac death. You have arrhythmias while you’re exercising.”

Harrington: You have a big, thick heart.

Patel: If you have hypertrophic cardiomyopathy, whether you’re an athlete or a 40-year-old adult, we’re going to have the same conversation. I think that holds. There’s a variety or a spectrum where we don’t know. I think the registry is one big step.

Thinking back to when somebody has an event, I would say take the teachable moment with the AHA and others to make sure your communities and your areas have automated external defibrillators (AEDs) and CPR training, and that we get to 100%: 100% response, 100% CPR, 100% defibrillation. I think that’s the first step.
 

Chain of survival

Harrington: Let’s really focus on the chain of survival. It is a chain: If any link is broken, your chance of survival really drops. We’ve had some well-known cases within our AHA community, including somebody who talks about it regularly: Kevin Volpp, from the University of Pennsylvania, a health economist. He had almost the perfect chain of survival. He had sudden cardiac death in a restaurant that was immediately observed, CPR started, EMTs called, and AED on the scene. Impressive.

Patel: That was in Cincinnati, where there are communities that have really worked on these things. I think you’re right. The chain of survival with rapid CPR to build a nation of survivors is key. The people at the AHA are helping us do this; there is a national call to make sure CPR is something that people feel comfortable doing. That they do it in men and women. They do it for anyone that goes down. And realize that it’s CPR that is hands-only. I think that’s an important lesson from Damar’s work, Nancy Brown’s, and AHA’s. Actually, schools in many countries require that to get through primary school.

Harrington: CPR training is a requirement to graduate from high school in some states.

Patel: My son just graduated from high school, and we spent time at his school making sure that everybody had access to CPR training. I think the way to do this is to start with that. Now, getting more specific about teams and athletes, I think most have emergency action plans, but it’s having action plans that work because of where you are and where the AED locations might be, or what the sport is. Having a plan on how you’re going to get that athlete to a place where you can help them recover is an important piece.

From there, I think the conversation for us is about what can we do as a society and as a country to answer some critical questions, including some real-world questions that people are asking: We had COVID-19 and we’re hearing these cases. Is this going up or down, and are these related?

Soon, hopefully the same group I talked about and others will have a publication, working with the NCAA to look at all of the deaths that they observed in NCAA Division I athletes over 20 years, including the sudden cardiac deaths. I won’t share the results because the publication isn’t out, but I think that’s the kind of important information that will help us understand if these rates are going up or down.

Harrington: What’s associated with that risk? Then we can start getting at whether it is something that, when we’re doing assessment for suitability for sports, has risk factors that should warrant more investigation.

Patel: Much like the field of cardiology, we haven’t enough of an evidence base, the right technologies, or the studies to determine how we should do screening, or not screening, across the board. Again, there is variation. There are some countries where anyone participating is going to get an ECG and an echocardiogram. There are other countries, like the United States, where it’s going to be a bit dependent on athlete risk.

Harrington: And where you live.

Patel: And where you live. Unfortunately, again, that brings in the idea that it might not be equitable in how we’re evaluating these individuals. I do think the opportunity to start to standardize that evaluation exists, and it likely comes from the ability to look back and say, “Here are some higher-risk individuals or some higher-risk scenarios.”

Harrington: Isn’t this what we do all the time in clinical medicine?

Patel: It’s going to be applied to a population that maybe is not as studied. I said this to you before we came on. The other thing is to make sure that the shared decision-making allows athletes who feel like they have a chance or want to play. During COVID, we had many college athletes, high school athletes, and kids not able to participate in sports. There was significant depression, feeling of loneliness, and even physical loss. People were actually getting less conditioned quickly. There’s a great benefit to sports participation.

Harrington: We were extrapolating from older data. If I’ve just had this new infection, COVID, and I’ve maybe got some signs of it in my heart, why can’t I exercise? That’s extrapolating from old myocarditis data.

Patel: We’re having to learn and follow it. I think there’s value in following that and getting those data. The second thing I think is really valuable is that we’ve shown that these individuals, if you do have these conversations and follow them, can participate and can be part of understanding the risk just like anything else.

Harrington: Is it sport specific? Are there some sports where maybe the conversation should be a little more intense than in other sports?

Patel: I think what we’ll see is that the conversations may be sport specific, and some may concern the number of athletes tested. At times, it’s pretty complicated. It does look like there are, as you know, different weight-bearing performance athletes, endurance athletes, or what I’ll call burst sports. There will probably be data that will identify certain sports where we may need to pay a bit more attention.

Harrington: What about the contact issues? Damar had a very specific thing, we think, happen to him. Football is a violent, contact-oriented sport, but fortunately we don’t regularly see what happened to Damar.

Patel: We’re talking about sudden cardiac death, but obviously, contact issues and neurologic evaluation is a whole other topic. That’s another big issue that I know many are following, and the NCAA is carefully, too. For Damar, I think we know that it was commotio cordis. At least when that happens, when there’s a ball or a trauma to the chest, those things have to be timed just so to actually lead to this event. Thankfully, it’s not very frequent, but it can happen.

Harrington: Hockey pucks, baseballs, soccer balls, a helmet to the chest ...

Patel: You have to be in a specific cycle of the squeeze. We don’t see that very frequently. I do think the evaluation and treatment, hopefully, makes a difference. One thing that we’re evolving in the screening world is our imaging; it’s getting better. We are not just doing echocardiograms; we are able to do other studies. There’s a mix of imaging and other technologies.

Is screening the answer?

Harrington: Let’s talk about that because screening is the area, I would say, with the most controversy – and a large amount of emotional controversy. Some argue that the data are not good enough to screen, or doctors are saying, “Wait a minute, why are we screening all these kids?” You said you were at your son’s high school doing CPR training. How many athletes are at his high school? There are many, and that’s a pretty small high school. Big communities, big universities, and the professional sports can afford it. Should we be doing this at the community level?

Patel: There have been some data. The Italians have done standard screening for some time, and it’s shown us that if you did echocardiograms in many individuals, you do find some cases that are hypertrophic cardiomyopathy in pathology. The issue is just how much you have to do and the resource utilization. I think as we get to a world where screening studies can happen with smaller technology and AI, that can be democratizing in how we get to athletes.

Harrington: Give an example of that. We were talking outside, you and I, about some of the new stethoscope technology.

Patel: Yes, stethoscopes are going to be one of the examples. We have stethoscopes that have the ability to get sounds and ECG signals, or at least some lead signals.

Harrington: Yes.

Patel: Potentially you can imagine that sound and ECG tracing in an AI environment, at least getting you from “everyone gets a listen with one stethoscope in their gym from their coach,” and it goes to the cloud. When there are enough questions, these are the ones that have to go further. Now, that’s a big study that has to be carried out; I’m not in any way saying we should do that.

Harrington: The technology is coming.

Patel: We start to see that our ability to rapidly do something to meet our athletes or our patients where they are will happen soon. Remember that the performance curve can vary, but once you have a sound where you can start to say that this is a regular flow murmur vs. “I’m worried about this,” especially as you mark it with ECG – that’s one example.

Smaller imaging is another example. For many years, ECGs have been talked about. There are entire courses that we run looking at ECGs in athletes. Remembering that Aaron Baggish and others are publishing that these individuals are large. When we look at their hearts, we see that they’re large, but when you adjust for size, often you can identify that many of them are within what we think are normal. Structurally, there are still many cases where you look at hearts and you’re asking, “Is this a thick heart? Is this noncompaction? Is this some pathology?”

That’s where you need imaging expertise. I think you have to have those individuals. I’m not advocating screening. I’m advocating studying it and that we should be thinking about the population. I don’t see a world where we don’t eventually start to really look to prevent those.

Harrington: Right. Whether it’s understanding that there are certain risk factors associated with this and we have to dedicate screening resources to those individuals, or if we want to do it more broadly on the population level to understand this with deeper dives into certain individuals, we’ve got to study it.

Patel: Some of the experts in sports medicine and sports cardiology have been collecting these data for a while. It’s time that we are there, because with these events we have the opportunity to share more of these data and maybe raise awareness – not in the teachable moment only – to get others to contribute.

I do believe that long term there’s an opportunity. We’ve seen that. We see that the rates, unfortunately, for marathon runners, where people unfortunately have events, seem to be higher. And we’ve seen the studies on troponin leaks in these individuals or evidence that there’s some effect on the heart from these events. We want people to be able to be long-term healthy.
 

Early defibrillation

Harrington: A large amount of work needs to be done. We talked with regard to screening, we’ve talked about CPR. We really need to have a nation of people who can do hands-only CPR. Let’s talk about AEDs, another key part of the chain of survival.

Patel: We have another important study going on, but an important message first: AEDs are critical to survival. We know that CPR is critical, but so is getting people to a defibrillator.

Harrington: Early defibrillation.

Patel: Early defibrillation. Early CPR is one of the biggest markers of making sure we perfuse people to get to early defibrillation, but then you have to get early defibrillation. There’s been a huge push in many communities, again, along with AHA and others, to make sure that AEDs are available not only in the U.S. but around the world. We’re at ESC and we see the push around the world to get AEDs available. They’ve come down in size and come down in cost, and that’s made it much more accessible. That’s really good. They’re still not always there.

We’ve seen really interesting randomized studies with people in some European countries where they have certain areas, just because of the locations, where bystanders will help get an AED  vs. randomizing to the EMS truck. They seem better in some of those variations. Chris Granger, at our institution, with Monique Starks, Dan Mark, and others, is doing a study in North Carolina where we’re testing different ways to potentially get AEDs in communities. We’re randomizing counties to one or two ways of getting AEDs to those individuals.

Harrington: Can you have an app where you just click “Find me an AED”?

Patel: Is there a world where the AED is found or is something bringing you the AED? Are there drones? Are there people driving? Are there ways that an AED is brought to the scene? All of those are going to be critical. It starts with continuing to figure out ways to support the costs of getting AEDs in places. The technology is continuing to evolve.

Harrington: It really is the premedical system stuff that makes the difference. Once EMS arrives with trained individuals who can defibrillate, they can transport you to a medical facility where trained physicians are at. It’s that pre-EMS thing that is so critical.

Patel: We talk often about athletes, but cardiac arrest care in general, and the chain of survival with CPR and AEDs, is critical. I still see patients in the CICU at Duke where, unfortunately, the biggest driver, as you just highlighted in that chain of survival, is how rapid we were in that golden hour. In the first 15 minutes, are you getting CPR, are you getting AED? Are you getting to a system?

Harrington: Are you getting a rapid transport?

Patel: Are you getting a neurologic assessment? Are you getting cooled or not? Those are important things.

Harrington: All right. Let’s try to wrap this up. Teachable moments, we talked about. One of the things about cases in prominent athletes is that it makes it to the newspaper and then it raises awareness. There is a drawing inference from a small group of cases to the broader societal issues. That’s an important topic.

We’ve talked about possible screening options, identifying at-risk individuals and high-risk individuals. A large amount of data has already been accumulated, but there is more work to be done. We focused on how to use those teachable moments to really influence the chain of survival, not just for athletes but for society at large.

I love your point about the Bethesda Conference on shared decision-making. Like with everything else, we have to have that two-way conversation: What are the athlete’s goals, hopes, and aspirations?

Patel: That group of experts, in addition to shared decision-making, gave us a whole list of conditions that we should be aware of and the cutpoints of where we think normal and not normal live for athletes. I think that’s used by many.

Can we build our systems to make research happen faster for the individuals? These athletes are at colleges that are obviously doing so much to make sure they’re okay. The people who are helping with this registry, and others, are going to continue to work to ask whether we can engage them as citizen participants and scientists. I think athletes are going to become some of our best advocates for why you’d want to know about yourself and how to perform CPR.

Harrington: I love the concept of citizen scientists, that we all have an obligation to contribute to the evidence base because we all want to use that evidence.

This has been a terrific conversation. I’ve been joined by my good friend, Dr. Manesh Patel from Duke University. I hope you’ve enjoyed our discussion here at the ESC. We have been taking a little break from the science going on around us to talk about sudden cardiac death in athletes. It really does have implications for broader societal concepts.

Robert A. Harrington, MD: I’m here with my good friend, Manesh Patel, from Duke University. We’re at the European Society of Cardiology (ESC) congress in Amsterdam, and I pulled Manesh into the studio for a conversation about something that’s really topical right now: sudden cardiac death in athletes.

What I hope to do [in this interview] is really pick Manesh’s brain on how we are thinking about this. Are we going to think about treatment issues? Are we going to think about prevention issues? Are we thinking about screening? We’ll try to make it practical.

Dr. Manesh Patel is chief of cardiovascular medicine at Duke University and also the director of the Duke Heart Center. Manesh, thanks for joining me here.
 

Bronny James and Damar Hamlin

Manesh R. Patel, MD: Excited to be here, Bob. Always.

Harrington: [Recently,] a news article comes out about the cause of Bronny James’ sudden cardiac death. Let me put this into a bigger societal context.

Last winter, Damar Hamlin, from the Buffalo Bills, suffered a traumatic injury on the field, and with that, had cardiac arrest. He’s back playing football – great to see. You and I are involved with the American Heart Association. He’s been very supportive of our efforts around things like CPR. He’s been terrific. It’s great to see him playing.

We know a little less about Bronny James. The news articles say the cause is both functional and anatomical, and it seems to be congenital, but we don’t have any details beyond this. Let’s not focus on the people; let’s focus on the topic.

Patel: I’m excited that we’re having the conversation. First and foremost, we’re excited that, with what we’ve seen on a national stage, these two individuals are doing well. They survived sudden cardiac death, which is a testament to all the things that we’ll talk about.

There are many important questions, like, is this increasing? Is this something we can prevent? And what are those things that might be happening to athletes?

Harrington: Can we predict it?

Patel: Right. I think the idea of sudden cardiac death in athletes is really a critical one for us to think about because it does concern participation and what we think about that. There are many experts who’ve been studying this for years that I now get to work with.

Harrington: Tell us a little bit about the kind of things you’ve been doing in this area.

Patel: Even before these events in the COVID era, we were wondering about athletes getting myocarditis, just in general, what do we know about that? People like Aaron Baggish, Kim Harmon, Jonathan Drezner, and others have been studying this.

Harrington: You and I did a show on athletes and COVID-19.

Patel: With the American Heart Association (AHA), the Cornell Foundation, and others, we started the Outcomes Registry for Cardiac Conditions in Athletes (ORCCA). This registry is across the United States, and athletes can sign up.

Harrington: Is it voluntary? Do the schools sign them up?

Patel: The athletes sign up. Team trainers and doctors talk to the athletes. We don’t really know the risks of some of these conditions. There’s a lot of gray area – people with certain conditions that were really interesting; aortas that are dilated in tall people.

Harrington: Long QT.

Patel: Long QT. There are certainly things that we know we should be intervening on and others where participation is a question. All of these we are trying to longitudinally put into the registry and follow them over time.

The second thing is understanding from the last Bethesda Conference that we want shared decision-making. There are going to be conditions where you say, “Look, I think your risk is high. You’ve a family history of sudden cardiac death. You have arrhythmias while you’re exercising.”

Harrington: You have a big, thick heart.

Patel: If you have hypertrophic cardiomyopathy, whether you’re an athlete or a 40-year-old adult, we’re going to have the same conversation. I think that holds. There’s a variety or a spectrum where we don’t know. I think the registry is one big step.

Thinking back to when somebody has an event, I would say take the teachable moment with the AHA and others to make sure your communities and your areas have automated external defibrillators (AEDs) and CPR training, and that we get to 100%: 100% response, 100% CPR, 100% defibrillation. I think that’s the first step.
 

Chain of survival

Harrington: Let’s really focus on the chain of survival. It is a chain: If any link is broken, your chance of survival really drops. We’ve had some well-known cases within our AHA community, including somebody who talks about it regularly: Kevin Volpp, from the University of Pennsylvania, a health economist. He had almost the perfect chain of survival. He had sudden cardiac death in a restaurant that was immediately observed, CPR started, EMTs called, and AED on the scene. Impressive.

Patel: That was in Cincinnati, where there are communities that have really worked on these things. I think you’re right. The chain of survival with rapid CPR to build a nation of survivors is key. The people at the AHA are helping us do this; there is a national call to make sure CPR is something that people feel comfortable doing. That they do it in men and women. They do it for anyone that goes down. And realize that it’s CPR that is hands-only. I think that’s an important lesson from Damar’s work, Nancy Brown’s, and AHA’s. Actually, schools in many countries require that to get through primary school.

Harrington: CPR training is a requirement to graduate from high school in some states.

Patel: My son just graduated from high school, and we spent time at his school making sure that everybody had access to CPR training. I think the way to do this is to start with that. Now, getting more specific about teams and athletes, I think most have emergency action plans, but it’s having action plans that work because of where you are and where the AED locations might be, or what the sport is. Having a plan on how you’re going to get that athlete to a place where you can help them recover is an important piece.

From there, I think the conversation for us is about what can we do as a society and as a country to answer some critical questions, including some real-world questions that people are asking: We had COVID-19 and we’re hearing these cases. Is this going up or down, and are these related?

Soon, hopefully the same group I talked about and others will have a publication, working with the NCAA to look at all of the deaths that they observed in NCAA Division I athletes over 20 years, including the sudden cardiac deaths. I won’t share the results because the publication isn’t out, but I think that’s the kind of important information that will help us understand if these rates are going up or down.

Harrington: What’s associated with that risk? Then we can start getting at whether it is something that, when we’re doing assessment for suitability for sports, has risk factors that should warrant more investigation.

Patel: Much like the field of cardiology, we haven’t enough of an evidence base, the right technologies, or the studies to determine how we should do screening, or not screening, across the board. Again, there is variation. There are some countries where anyone participating is going to get an ECG and an echocardiogram. There are other countries, like the United States, where it’s going to be a bit dependent on athlete risk.

Harrington: And where you live.

Patel: And where you live. Unfortunately, again, that brings in the idea that it might not be equitable in how we’re evaluating these individuals. I do think the opportunity to start to standardize that evaluation exists, and it likely comes from the ability to look back and say, “Here are some higher-risk individuals or some higher-risk scenarios.”

Harrington: Isn’t this what we do all the time in clinical medicine?

Patel: It’s going to be applied to a population that maybe is not as studied. I said this to you before we came on. The other thing is to make sure that the shared decision-making allows athletes who feel like they have a chance or want to play. During COVID, we had many college athletes, high school athletes, and kids not able to participate in sports. There was significant depression, feeling of loneliness, and even physical loss. People were actually getting less conditioned quickly. There’s a great benefit to sports participation.

Harrington: We were extrapolating from older data. If I’ve just had this new infection, COVID, and I’ve maybe got some signs of it in my heart, why can’t I exercise? That’s extrapolating from old myocarditis data.

Patel: We’re having to learn and follow it. I think there’s value in following that and getting those data. The second thing I think is really valuable is that we’ve shown that these individuals, if you do have these conversations and follow them, can participate and can be part of understanding the risk just like anything else.

Harrington: Is it sport specific? Are there some sports where maybe the conversation should be a little more intense than in other sports?

Patel: I think what we’ll see is that the conversations may be sport specific, and some may concern the number of athletes tested. At times, it’s pretty complicated. It does look like there are, as you know, different weight-bearing performance athletes, endurance athletes, or what I’ll call burst sports. There will probably be data that will identify certain sports where we may need to pay a bit more attention.

Harrington: What about the contact issues? Damar had a very specific thing, we think, happen to him. Football is a violent, contact-oriented sport, but fortunately we don’t regularly see what happened to Damar.

Patel: We’re talking about sudden cardiac death, but obviously, contact issues and neurologic evaluation is a whole other topic. That’s another big issue that I know many are following, and the NCAA is carefully, too. For Damar, I think we know that it was commotio cordis. At least when that happens, when there’s a ball or a trauma to the chest, those things have to be timed just so to actually lead to this event. Thankfully, it’s not very frequent, but it can happen.

Harrington: Hockey pucks, baseballs, soccer balls, a helmet to the chest ...

Patel: You have to be in a specific cycle of the squeeze. We don’t see that very frequently. I do think the evaluation and treatment, hopefully, makes a difference. One thing that we’re evolving in the screening world is our imaging; it’s getting better. We are not just doing echocardiograms; we are able to do other studies. There’s a mix of imaging and other technologies.

Is screening the answer?

Harrington: Let’s talk about that because screening is the area, I would say, with the most controversy – and a large amount of emotional controversy. Some argue that the data are not good enough to screen, or doctors are saying, “Wait a minute, why are we screening all these kids?” You said you were at your son’s high school doing CPR training. How many athletes are at his high school? There are many, and that’s a pretty small high school. Big communities, big universities, and the professional sports can afford it. Should we be doing this at the community level?

Patel: There have been some data. The Italians have done standard screening for some time, and it’s shown us that if you did echocardiograms in many individuals, you do find some cases that are hypertrophic cardiomyopathy in pathology. The issue is just how much you have to do and the resource utilization. I think as we get to a world where screening studies can happen with smaller technology and AI, that can be democratizing in how we get to athletes.

Harrington: Give an example of that. We were talking outside, you and I, about some of the new stethoscope technology.

Patel: Yes, stethoscopes are going to be one of the examples. We have stethoscopes that have the ability to get sounds and ECG signals, or at least some lead signals.

Harrington: Yes.

Patel: Potentially you can imagine that sound and ECG tracing in an AI environment, at least getting you from “everyone gets a listen with one stethoscope in their gym from their coach,” and it goes to the cloud. When there are enough questions, these are the ones that have to go further. Now, that’s a big study that has to be carried out; I’m not in any way saying we should do that.

Harrington: The technology is coming.

Patel: We start to see that our ability to rapidly do something to meet our athletes or our patients where they are will happen soon. Remember that the performance curve can vary, but once you have a sound where you can start to say that this is a regular flow murmur vs. “I’m worried about this,” especially as you mark it with ECG – that’s one example.

Smaller imaging is another example. For many years, ECGs have been talked about. There are entire courses that we run looking at ECGs in athletes. Remembering that Aaron Baggish and others are publishing that these individuals are large. When we look at their hearts, we see that they’re large, but when you adjust for size, often you can identify that many of them are within what we think are normal. Structurally, there are still many cases where you look at hearts and you’re asking, “Is this a thick heart? Is this noncompaction? Is this some pathology?”

That’s where you need imaging expertise. I think you have to have those individuals. I’m not advocating screening. I’m advocating studying it and that we should be thinking about the population. I don’t see a world where we don’t eventually start to really look to prevent those.

Harrington: Right. Whether it’s understanding that there are certain risk factors associated with this and we have to dedicate screening resources to those individuals, or if we want to do it more broadly on the population level to understand this with deeper dives into certain individuals, we’ve got to study it.

Patel: Some of the experts in sports medicine and sports cardiology have been collecting these data for a while. It’s time that we are there, because with these events we have the opportunity to share more of these data and maybe raise awareness – not in the teachable moment only – to get others to contribute.

I do believe that long term there’s an opportunity. We’ve seen that. We see that the rates, unfortunately, for marathon runners, where people unfortunately have events, seem to be higher. And we’ve seen the studies on troponin leaks in these individuals or evidence that there’s some effect on the heart from these events. We want people to be able to be long-term healthy.
 

Early defibrillation

Harrington: A large amount of work needs to be done. We talked with regard to screening, we’ve talked about CPR. We really need to have a nation of people who can do hands-only CPR. Let’s talk about AEDs, another key part of the chain of survival.

Patel: We have another important study going on, but an important message first: AEDs are critical to survival. We know that CPR is critical, but so is getting people to a defibrillator.

Harrington: Early defibrillation.

Patel: Early defibrillation. Early CPR is one of the biggest markers of making sure we perfuse people to get to early defibrillation, but then you have to get early defibrillation. There’s been a huge push in many communities, again, along with AHA and others, to make sure that AEDs are available not only in the U.S. but around the world. We’re at ESC and we see the push around the world to get AEDs available. They’ve come down in size and come down in cost, and that’s made it much more accessible. That’s really good. They’re still not always there.

We’ve seen really interesting randomized studies with people in some European countries where they have certain areas, just because of the locations, where bystanders will help get an AED  vs. randomizing to the EMS truck. They seem better in some of those variations. Chris Granger, at our institution, with Monique Starks, Dan Mark, and others, is doing a study in North Carolina where we’re testing different ways to potentially get AEDs in communities. We’re randomizing counties to one or two ways of getting AEDs to those individuals.

Harrington: Can you have an app where you just click “Find me an AED”?

Patel: Is there a world where the AED is found or is something bringing you the AED? Are there drones? Are there people driving? Are there ways that an AED is brought to the scene? All of those are going to be critical. It starts with continuing to figure out ways to support the costs of getting AEDs in places. The technology is continuing to evolve.

Harrington: It really is the premedical system stuff that makes the difference. Once EMS arrives with trained individuals who can defibrillate, they can transport you to a medical facility where trained physicians are at. It’s that pre-EMS thing that is so critical.

Patel: We talk often about athletes, but cardiac arrest care in general, and the chain of survival with CPR and AEDs, is critical. I still see patients in the CICU at Duke where, unfortunately, the biggest driver, as you just highlighted in that chain of survival, is how rapid we were in that golden hour. In the first 15 minutes, are you getting CPR, are you getting AED? Are you getting to a system?

Harrington: Are you getting a rapid transport?

Patel: Are you getting a neurologic assessment? Are you getting cooled or not? Those are important things.

Harrington: All right. Let’s try to wrap this up. Teachable moments, we talked about. One of the things about cases in prominent athletes is that it makes it to the newspaper and then it raises awareness. There is a drawing inference from a small group of cases to the broader societal issues. That’s an important topic.

We’ve talked about possible screening options, identifying at-risk individuals and high-risk individuals. A large amount of data has already been accumulated, but there is more work to be done. We focused on how to use those teachable moments to really influence the chain of survival, not just for athletes but for society at large.

I love your point about the Bethesda Conference on shared decision-making. Like with everything else, we have to have that two-way conversation: What are the athlete’s goals, hopes, and aspirations?

Patel: That group of experts, in addition to shared decision-making, gave us a whole list of conditions that we should be aware of and the cutpoints of where we think normal and not normal live for athletes. I think that’s used by many.

Can we build our systems to make research happen faster for the individuals? These athletes are at colleges that are obviously doing so much to make sure they’re okay. The people who are helping with this registry, and others, are going to continue to work to ask whether we can engage them as citizen participants and scientists. I think athletes are going to become some of our best advocates for why you’d want to know about yourself and how to perform CPR.

Harrington: I love the concept of citizen scientists, that we all have an obligation to contribute to the evidence base because we all want to use that evidence.

This has been a terrific conversation. I’ve been joined by my good friend, Dr. Manesh Patel from Duke University. I hope you’ve enjoyed our discussion here at the ESC.

Harrington: Hockey pucks, baseballs, soccer balls, a helmet to the chest ...

Patel: You have to be in a specific cycle of the squeeze. We don’t see that very frequently. I do think the evaluation and treatment, hopefully, makes a difference. One thing that we’re evolving in the screening world is our imaging; it’s getting better. We are not just doing echocardiograms; we are able to do other studies. There’s a mix of imaging and other technologies.

Is screening the answer?

Harrington: Let’s talk about that because screening is the area, I would say, with the most controversy – and a large amount of emotional controversy. Some argue that the data are not good enough to screen, or doctors are saying, “Wait a minute, why are we screening all these kids?” You said you were at your son’s high school doing CPR training. How many athletes are at his high school? There are many, and that’s a pretty small high school. Big communities, big universities, and the professional sports can afford it. Should we be doing this at the community level?

Patel: There have been some data. The Italians have done standard screening for some time, and it’s shown us that if you did echocardiograms in many individuals, you do find some cases that are hypertrophic cardiomyopathy in pathology. The issue is just how much you have to do and the resource utilization. I think as we get to a world where screening studies can happen with smaller technology and AI, that can be democratizing in how we get to athletes.

Harrington: Give an example of that. We were talking outside, you and I, about some of the new stethoscope technology.

Patel: Yes, stethoscopes are going to be one of the examples. We have stethoscopes that have the ability to get sounds and ECG signals, or at least some lead signals.

Harrington: Yes.

Patel: Potentially you can imagine that sound and ECG tracing in an AI environment, at least getting you from “everyone gets a listen with one stethoscope in their gym from their coach,” and it goes to the cloud. When there are enough questions, these are the ones that have to go further. Now, that’s a big study that has to be carried out; I’m not in any way saying we should do that.

Harrington: The technology is coming.

Patel: We start to see that our ability to rapidly do something to meet our athletes or our patients where they are will happen soon. Remember that the performance curve can vary, but once you have a sound where you can start to say that this is a regular flow murmur vs. “I’m worried about this,” especially as you mark it with ECG – that’s one example.

Smaller imaging is another example. For many years, ECGs have been talked about. There are entire courses that we run looking at ECGs in athletes. Remembering that Aaron Baggish and others are publishing that these individuals are large. When we look at their hearts, we see that they’re large, but when you adjust for size, often you can identify that many of them are within what we think are normal. Structurally, there are still many cases where you look at hearts and you’re asking, “Is this a thick heart? Is this noncompaction? Is this some pathology?”

That’s where you need imaging expertise. I think you have to have those individuals. I’m not advocating screening. I’m advocating studying it and that we should be thinking about the population. I don’t see a world where we don’t eventually start to really look to prevent those.

Harrington: Right. Whether it’s understanding that there are certain risk factors associated with this and we have to dedicate screening resources to those individuals, or if we want to do it more broadly on the population level to understand this with deeper dives into certain individuals, we’ve got to study it.

Patel: Some of the experts in sports medicine and sports cardiology have been collecting these data for a while. It’s time that we are there, because with these events we have the opportunity to share more of these data and maybe raise awareness – not in the teachable moment only – to get others to contribute.

I do believe that long term there’s an opportunity. We’ve seen that. We see that the rates, unfortunately, for marathon runners, where people unfortunately have events, seem to be higher. And we’ve seen the studies on troponin leaks in these individuals or evidence that there’s some effect on the heart from these events. We want people to be able to be long-term healthy.
 

Early defibrillation

Harrington: A large amount of work needs to be done. We talked with regard to screening, we’ve talked about CPR. We really need to have a nation of people who can do hands-only CPR. Let’s talk about AEDs, another key part of the chain of survival.

Patel: We have another important study going on, but an important message first: AEDs are critical to survival. We know that CPR is critical, but so is getting people to a defibrillator.

Harrington: Early defibrillation.

Patel: Early defibrillation. Early CPR is one of the biggest markers of making sure we perfuse people to get to early defibrillation, but then you have to get early defibrillation. There’s been a huge push in many communities, again, along with AHA and others, to make sure that AEDs are available not only in the U.S. but around the world. We’re at ESC and we see the push around the world to get AEDs available. They’ve come down in size and come down in cost, and that’s made it much more accessible. That’s really good. They’re still not always there.

We’ve seen really interesting randomized studies with people in some European countries where they have certain areas, just because of the locations, where bystanders will help get an AED  vs. randomizing to the EMS truck. They seem better in some of those variations. Chris Granger, at our institution, with Monique Starks, Dan Mark, and others, is doing a study in North Carolina where we’re testing different ways to potentially get AEDs in communities. We’re randomizing counties to one or two ways of getting AEDs to those individuals.

Harrington: Can you have an app where you just click “Find me an AED”?

Patel: Is there a world where the AED is found or is something bringing you the AED? Are there drones? Are there people driving? Are there ways that an AED is brought to the scene? All of those are going to be critical. It starts with continuing to figure out ways to support the costs of getting AEDs in places. The technology is continuing to evolve.

Harrington: It really is the premedical system stuff that makes the difference. Once EMS arrives with trained individuals who can defibrillate, they can transport you to a medical facility where trained physicians are at. It’s that pre-EMS thing that is so critical.

Patel: We talk often about athletes, but cardiac arrest care in general, and the chain of survival with CPR and AEDs, is critical. I still see patients in the CICU at Duke where, unfortunately, the biggest driver, as you just highlighted in that chain of survival, is how rapid we were in that golden hour. In the first 15 minutes, are you getting CPR, are you getting AED? Are you getting to a system?

Harrington: Are you getting a rapid transport?

Patel: Are you getting a neurologic assessment? Are you getting cooled or not? Those are important things.

Harrington: All right. Let’s try to wrap this up. Teachable moments, we talked about. One of the things about cases in prominent athletes is that it makes it to the newspaper and then it raises awareness. There is a drawing inference from a small group of cases to the broader societal issues. That’s an important topic.

We’ve talked about possible screening options, identifying at-risk individuals and high-risk individuals. A large amount of data has already been accumulated, but there is more work to be done. We focused on how to use those teachable moments to really influence the chain of survival, not just for athletes but for society at large.

I love your point about the Bethesda Conference on shared decision-making. Like with everything else, we have to have that two-way conversation: What are the athlete’s goals, hopes, and aspirations?

Patel: That group of experts, in addition to shared decision-making, gave us a whole list of conditions that we should be aware of and the cutpoints of where we think normal and not normal live for athletes. I think that’s used by many.

Can we build our systems to make research happen faster for the individuals? These athletes are at colleges that are obviously doing so much to make sure they’re okay. The people who are helping with this registry, and others, are going to continue to work to ask whether we can engage them as citizen participants and scientists. I think athletes are going to become some of our best advocates for why you’d want to know about yourself and how to perform CPR.

Harrington: I love the concept of citizen scientists, that we all have an obligation to contribute to the evidence base because we all want to use that evidence.

This has been a terrific conversation. I’ve been joined by my good friend, Dr. Manesh Patel from Duke University. I hope you’ve enjoyed our discussion here at the ESC. We have been taking a little break from the science going on around us to talk about sudden cardiac death in athletes. It really does have implications for broader societal concepts.

AMSTERDAM – New European Society of Cardiology guidelines on the management of acute coronary syndromes (ACS) have for the first time combined ST-elevation MI (STEMI), non–ST-elevation MI (NSTEMI), and unstable angina into the same set of recommendations.

The new guideline was released at the annual congress of the European Society of Cardiology, and was published online in the European Heart Journal.

“We found that it was realized by the cardiology community that patients with STEMI, NSTEMI, or unstable angina represent a spectrum,” the chair of the guideline task force, Robert Byrne, MD, chair of cardiovascular research at the RCSI University of Medicine and Health Sciences, Dublin, explained to this news organization. “After the initial triage and management decisions, then most of the rest of the care follows a common pathway so it would make sense to consider everything in one guideline.”

Dr. Byrne noted that for all patients with a suspected ACS, the guideline recommendation is to administer an ECG within 10 minutes of presentation. The time is critical particularly for those with an occluded epicardial vessel. If there are features on the ECG that suggest an acutely occluded epicardial vessel, then the patient needs immediate angiography or primary angioplasty.

“The 10-minute guidance has been maintained from previous guidelines, but the nuance in the new guideline is that typically when we think of an occluded epicardial vessel we think of ST-elevation on the ECG,” Byrne said. “While this captures most occluded epicardial vessels, it doesn’t capture all of them. So, we have provided some guidance on alternative ECG patterns which might be indicative of an acute occlusion of the epicardial vessel and should be dealt with in the same way as an ST-elevation MI. This is a new concept.”

This situation could arise when a patient has an occluded circumflex artery and the regular ECG may not show ST elevation but the patient has ongoing pain, he noted. “There are additional ECG leads that can be looked at that might identify patients who need an immediate invasive strategy.

“This is one more reason why all ACS patients should be considered as part of one spectrum, and while the ECG gives us important information, it is not the only thing to consider. Dividing the conditions up as to whether a patient has ST elevation or not does not always make pathophysiological sense,” he added.

Dr. Byrne noted that the new guidelines have tried to reach a wider stakeholder group that includes emergency doctors, internal medicine physicians, general practitioners, and surgeons, as well as cardiologists. The document includes animations in an effort to increase the reach of the guidelines to noncardiology stakeholders, and for the first time, the task force included a patient representative.

“As part of this strategy, we have put more structure in to emphasize the importance that at first contact, we already want to be thinking of antithrombotic therapy and whether the patient needs urgent transfer to the nearest cath lab. We also want to be thinking straight away about preventing the next heart attack by implementing strong secondary prevention measures,” he commented.

Dr. Byrne highlighted a few changes to individual recommendations in the new guidelines.
 

Invasive management in NSTE-ACS

He pointed out that a small change has been made in the advice on invasive management for patients with non–ST-elevation ACS.

Dr. Byrne explained that patients with ST elevation should be sent immediately to a cath lab for PCI. If this is not possible within 120 minutes, then the patient should receive thrombolysis. This recommendation is the same as in previous guidelines.

He added, however, that there is some novelty in recommendations for patients who don’t have ST elevation but do have a positive troponin. For this group, previous guidelines gave a Class I recommendation that all such patients undergo an angiogram within the first 24 hours. However, an additional meta-analysis that was published in 2022 showed that the evidence for triaging all patients to the cath lab within 24 hours is somewhat limited, Dr. Byrne noted.

“At the end of the day, the task force felt that a Class I recommendation to get all patients to the cath lab within 24 hours was too strong and couldn’t be sustained, so it has been downgraded to a Class IIa recommendation, which we thought was more appropriate,” he said.

“So, while all patients should still have an angiogram during the hospital admission, if they are high-risk ACS, the imperative to get everyone to the cath lab within 24 hours – which many of our colleagues were finding difficult to achieve – does not seem to be backed up by the evidence,” he added.
 

Antithrombotic therapy

Addressing administration of antithrombotics, the guidelines emphasize that at the time of initial diagnosis, all patients should receive antithrombotic therapy, usually aspirin and a parenteral antithrombotic, such as heparin, enoxaparin, bivalirudin, or fondaparinux. Dr. Byrne noted that the guidelines have a new algorithm as to which of these antithrombotics to give, depending on the clinical presentation of the patient.

On the use of upfront P2Y12 inhibitors, Dr. Byrne said the new guidelines only give a weak recommendation for this.

“Giving a P2Y12 inhibitor up front does not have a strong evidence base, and it’s not unreasonable to wait, do the angiogram, see where you are, and then start the P2Y12 inhibitor. This is something that’s not widely done in clinical practice,” he commented.

“The last 2020 guideline gave a Class III recommendation for upfront P2Y12 inhibitor therapy for ACS patients who do not have STEMI. We’ve generally maintained that with the introduction of the exception that if you are in a health care system where there is a long wait to get to the cath lab – 5 ,6 or 7 days – then it’s reasonable to make an exception and give a P2Y12 inhibitor, but otherwise we’ve sustained the Class III recommendation,” he noted.

Also, for patients who have STEMI, there is a new Class IIb recommendation that upfront P2Y12 inhibitors may be considered.

“This is also rather a weak recommendation. There isn’t a strong rationale to give a P2Y12 inhibitor it in ST elevation either. It’s also reasonable to wait,” he added.
 

Don’t rush cardiac arrest patients to the cath lab

Another update in the guidelines involves the management of patients with cardiac arrest who have been resuscitated. Dr. Byrne explained that these patients would all receive an immediate ECG, and if it is found that they have ST elevation, they would be sent immediately to the cath lab. But a series of randomized trials has suggested that for patients who don’t have ST elevation, it is not necessary to rush these patients to the cath lab.

“We’ve given a Class III recommendation for this, saying it may be better to stabilize the patients first in the ICU. This is in recognition that a large proportion of these patients turn out not to have an MI. They have had a cardiac arrest for another reason,” Dr. Byrne noted. “Moving them to the cath lab when they are still unstable could be harming these patients rather than helping them.”
 

Revascularization for multivessel disease

Dr. Byrne notes that revascularization remains a critical element in the care for patients with STEMI, and there is a new recommendation in this area for patients with multivessel disease.

“Up to half of patients presenting with STEMI have multivessel disease, and we now have five randomized trials to say that these patients should have complete revascularization rather than just the culprit vessel. There is a new Class I recommendation for this,” he said.

However, the optimal timing of revascularization (immediate vs. staged) has still not been investigated in adequately sized randomized trials, and no recommendation has been made on this, the task force notes.

Dr. Byrne commented: “If you want to do everything in one go, that’s fine, but it’s also okay to do the culprit lesion first and then the other vessels at a later date within 45 days. This might depend on individual circumstances. For example, if there are complex lesions or the vessels are heavily calcified, then it may be best to get the culprit lesion fixed first and let the patient recover, then bring them back in for the rest.”

He pointed out that the results of the MULTISTARS trial, which were not available when the task force was formulating the guidelines, were reported at the ESC Congress and confirmed their recommendation.
 

DAPT after PCI

On the duration of dual antiplatelet therapy (DAPT) after PCI, the new guidelines have largely retained prior recommendations for a default strategy of 12 months for the combination of aspirin and a P2Y12 inhibitor.

“This was the subject of some discussion, as there have been several trials now looking at shorter durations of DAPT and deescalating after a few months to just one of these treatments. And while there is a rationale to do this, we think it’s best to be kept as an alternative strategy rather than the default strategy,” Dr. Byrne said.

He explained that the trials of DAPT deescalation tended to enroll lower-risk patients, which reduced the generalizability of the results.

Most of the trials only randomly assigned patients to shorter durations of DAPT when they were event-free for some period, she said.

“This is a dynamic decision-making process and reflects the real world to some extent. We think it is best to recommend the standard aspirin and a P2Y12 inhibitor for the 12-month duration, but at 3 months, if the patient is doing well but you may be worried about bleeding risk, then you could decide to deescalate to single antiplatelet therapy,” she noted. “So, there is Class IIa recommendation that this can be considered, but it is not recommended as the default position.”
 

Polypill for secondary prevention

Another innovation in the new guidelines is a new Class IIa recommendation for prescription of a polypill containing secondary prevention medications for patients on discharge from hospital.

This recommendation follows a trial that showed that the use of such a polypill helps patients be more adherent to the therapies prescribed.

Byrne explains that such a polypill may contain aspirin, an ACE inhibitor, and a statin. Several varieties are available in most European countries, but they are not widely used.

On secondary prevention, he stressed, “Prevention of the next heart attack starts before the patient leaves hospital. It is important to make sure the patient has the right medication on board, including a high-dose, high-intensity statin, and has been referred to a cardiac rehabilitation program. These are largely maintained recommendations from previous guidelines, but they are very important.”

However, an additional meta-analysis that was published in 2022 showed that the evidence for triaging all patients to the cath lab within 24 hours is somewhat limited, Dr. Byrne noted.

“At the end of the day, the task force felt that a Class I recommendation to get all patients to the cath lab within 24 hours was too strong and couldn’t be sustained, so it has been downgraded to a Class IIa recommendation, which we thought was more appropriate,” he said.

“So, while all patients should still have an angiogram during the hospital admission, if they are high-risk ACS, the imperative to get everyone to the cath lab within 24 hours – which many of our colleagues were finding difficult to achieve – does not seem to be backed up by the evidence,” he added.
 

Antithrombotic therapy

Addressing administration of antithrombotics, the guidelines emphasize that at the time of initial diagnosis, all patients should receive antithrombotic therapy, usually aspirin and a parenteral antithrombotic, such as heparin, enoxaparin, bivalirudin, or fondaparinux. Dr. Byrne noted that the guidelines have a new algorithm as to which of these antithrombotics to give, depending on the clinical presentation of the patient.

On the use of upfront P2Y12 inhibitors, Dr. Byrne said the new guidelines only give a weak recommendation for this.

“Giving a P2Y12 inhibitor up front does not have a strong evidence base, and it’s not unreasonable to wait, do the angiogram, see where you are, and then start the P2Y12 inhibitor. This is something that’s not widely done in clinical practice,” he commented.

“The last 2020 guideline gave a Class III recommendation for upfront P2Y12 inhibitor therapy for ACS patients who do not have STEMI. We’ve generally maintained that with the introduction of the exception that if you are in a health care system where there is a long wait to get to the cath lab – 5 ,6 or 7 days – then it’s reasonable to make an exception and give a P2Y12 inhibitor, but otherwise we’ve sustained the Class III recommendation,” he noted.

Also, for patients who have STEMI, there is a new Class IIb recommendation that upfront P2Y12 inhibitors may be considered.

“This is also rather a weak recommendation. There isn’t a strong rationale to give a P2Y12 inhibitor it in ST elevation either. It’s also reasonable to wait,” he added.
 

Don’t rush cardiac arrest patients to the cath lab

Another update in the guidelines involves the management of patients with cardiac arrest who have been resuscitated. Dr. Byrne explained that these patients would all receive an immediate ECG, and if it is found that they have ST elevation, they would be sent immediately to the cath lab. But a series of randomized trials has suggested that for patients who don’t have ST elevation, it is not necessary to rush these patients to the cath lab.

“We’ve given a Class III recommendation for this, saying it may be better to stabilize the patients first in the ICU. This is in recognition that a large proportion of these patients turn out not to have an MI. They have had a cardiac arrest for another reason,” Dr. Byrne noted. “Moving them to the cath lab when they are still unstable could be harming these patients rather than helping them.”
 

Revascularization for multivessel disease

Dr. Byrne notes that revascularization remains a critical element in the care for patients with STEMI, and there is a new recommendation in this area for patients with multivessel disease.

“Up to half of patients presenting with STEMI have multivessel disease, and we now have five randomized trials to say that these patients should have complete revascularization rather than just the culprit vessel. There is a new Class I recommendation for this,” he said.

However, the optimal timing of revascularization (immediate vs. staged) has still not been investigated in adequately sized randomized trials, and no recommendation has been made on this, the task force notes.

Dr. Byrne commented: “If you want to do everything in one go, that’s fine, but it’s also okay to do the culprit lesion first and then the other vessels at a later date within 45 days. This might depend on individual circumstances. For example, if there are complex lesions or the vessels are heavily calcified, then it may be best to get the culprit lesion fixed first and let the patient recover, then bring them back in for the rest.”

He pointed out that the results of the MULTISTARS trial, which were not available when the task force was formulating the guidelines, were reported at the ESC Congress and confirmed their recommendation.
 

DAPT after PCI

On the duration of dual antiplatelet therapy (DAPT) after PCI, the new guidelines have largely retained prior recommendations for a default strategy of 12 months for the combination of aspirin and a P2Y12 inhibitor.

“This was the subject of some discussion, as there have been several trials now looking at shorter durations of DAPT and deescalating after a few months to just one of these treatments. And while there is a rationale to do this, we think it’s best to be kept as an alternative strategy rather than the default strategy,” Dr. Byrne said.

He explained that the trials of DAPT deescalation tended to enroll lower-risk patients, which reduced the generalizability of the results.

Most of the trials only randomly assigned patients to shorter durations of DAPT when they were event-free for some period, she said.

“This is a dynamic decision-making process and reflects the real world to some extent. We think it is best to recommend the standard aspirin and a P2Y12 inhibitor for the 12-month duration, but at 3 months, if the patient is doing well but you may be worried about bleeding risk, then you could decide to deescalate to single antiplatelet therapy,” she noted. “So, there is Class IIa recommendation that this can be considered, but it is not recommended as the default position.”
 

Polypill for secondary prevention

Another innovation in the new guidelines is a new Class IIa recommendation for prescription of a polypill containing secondary prevention medications for patients on discharge from hospital.

This recommendation follows a trial that showed that the use of such a polypill helps patients be more adherent to the therapies prescribed.

Byrne explains that such a polypill may contain aspirin, an ACE inhibitor, and a statin. Several varieties are available in most European countries, but they are not widely used.

On secondary prevention, he stressed, “Prevention of the next heart attack starts before the patient leaves hospital. It is important to make sure the patient has the right medication on board, including a high-dose, high-intensity statin, and has been referred to a cardiac rehabilitation program. These are largely maintained recommendations from previous guidelines, but they are very important.”

Michelle L. O’Donoghue, MD, MPH: Hi. This is Dr. Michelle O’Donoghue reporting for Medscape. Joining me today is Dr. Sahil Parikh, who’s a cardiologist and an interventionalist at Columbia University. He’s an associate professor of medicine.

We’ll be discussing two interesting trials that were presented at the ESC Congress here in Amsterdam. They do have the potential to be very practice-changing, so I think it’s worth talking about.
 

The FIRE trial

The first trial we’ll be talking about is the FIRE trial. Perhaps setting the stage, Sahil, I’d love to get your thoughts. We’ve had data in this space to suggest that, for patients with STEMI [ST-segment elevation myocardial infarction], a strategy of complete revascularization – and not only treating the culprit lesion but also treating additional lesions – may be of benefit. Where does that lead us in terms of what we didn’t know?

Sahil A. Parikh, MD: I think that the practice has moved, at least in the United States, over the past two decades, from staging percutaneous coronary interventions over 30 days from index to intervention to now trying to do patients in the same hospitalization whenever possible to achieve complete revascularization.

I think these data support not only that complete revascularization is compulsory now in these patients, but also doing it sooner rather than later, and that the benefit applies to most of the patients that we see in clinical practice. In the earlier data, the patients were relatively youthful – under Medicare age, less than 65 – and now this dataset has a median age of 80. This is more like the real-world clinical practice that most of us are encountering, and it extends the benefit, perhaps, greater than we’ve ever seen before.

O’Donoghue: The FIRE trial is interesting. As you say, it enrolled patients who were over the age of 75, where I think that some proceduralists are probably a little bit hesitant to think about complete revascularization due to concerns about any additional contrast load on their kidneys and other types of comorbidities. Of course, for any trial, there’s going to be some patient selection.

I think it’s very reassuring that even in this older patient group, a strategy of treating all the lesions – and not only in STEMI but also in non-STEMI patients – reduced cardiovascular events and mortality. I was really quite impressed by the mortality benefit.

Parikh: The mortality curve is almost surprising to me. On the other hand, it emboldens us now that we can treat these patients more completely and earlier in their clinical presentation. Certainly, we worried about contrast exposure and the duration of procedures in this older population, but it seems that the benefit that’s derived, which we saw in younger patients where we had a natural inclination to be more aggressive, extends also to this older population.
 

MULTISTARS AMI

O’Donoghue: To the question of timing, as you mentioned, prior to this, we had a study presented earlier this year, the BIOVASC trial, which also was suggestive that maybe earlier complete revascularization was better. But it wasn’t a significant difference, at least for the primary outcome. Now we have MULTISTARS AMI, which is very supportive of what we saw earlier this year, suggesting that complete revascularization really at the time that you’re treating the culprit may be the way to go.

Parikh: All of us, as interventionalists, are circumspect about what we might do in the middle of the night versus what we would do in the light of day. Certainly it seems clear, particularly if it’s straightforward anatomy, that taking care of it in the index procedure is not only saving contrast and fluoroscopy time, but it’s also providing a clinical benefit to the patients. That’s something that will also impact how clinicians interpret these data. Previously, there was always a question about whether we should just do it in the same hospitalization or do it at the same time. I think now, increasingly, we’re emboldened to do more in the index procedure.

O’Donoghue: When you’re thinking about nonculprit lesions and which ones to treat, do you always make that determination based on physiologic guidance of some kind? Are you using instantaneous wave-free ratio? What’s your practice?

Parikh: In the acute setting, imaging is superior for at least the assessment of which is a culprit. If you see a ruptured atherothrombotic situation on optical coherence tomography, for example, that’s fairly convincing and definitive. In the absence of that physiology, we are taught to avoid in the infarct-related artery because of potential spuriously false-negative findings.

In this situation, certainly, an imaging subgroup probably would be helpful because some of the benefit is almost certainly derived from identifying the infarct-related artery by accident – in other words, doing what you thought was the nonculprit artery, which is, in fact, the culprit. I think that probably is part of this. As somebody who uses imaging in the overwhelming number of my cases, I think that imaging would be an important surrogate to this.
 

Index procedure versus staged

O’Donoghue: For the operator who is coming in to do their STEMI case at 2:00 in the morning, would these data now push you toward doing complete revascularization at that time of night, or do you think that there is wiggle room in terms of interpreting these results regarding timing, where as long as you were doing it before hospital discharge and not, let’s say, 30 days out, that you may be able to derive the same benefit? What are some of the pros and cons?

Parikh: There’s definitely a fatigue factor in the middle of the night if it’s a particularly arduous intervention for the index infarct-related artery. I think there’s a human element where it may make sense just to stop and then bring the patient back in the same hospitalization. It’s clear, though, that doing complete revascularization is better and doing it sooner is better. How soon one actually does it is a judgment call, as ever.

In our practice, we’ve been pushing ourselves to get most of the patients done in their index hospitalization. If you have a left-sided culprit, the left anterior descending artery, for example, and there’s a high-grade stenosis in the circumflex, it may make sense to take care of that in the same index procedure. If, on the other hand, it’s in the right coronary artery where you have to put a new guide in and spend more time, that may be a patient whom you stage. I think those nuances will come up as interventionalists look at the subgroup analysis data more carefully.

O’Donoghue: Those are great points, and I think they also underscore that we always need to think about what type of patient was enrolled in these studies. Certainly, if you have somebody with renal dysfunction, there might be more concern about giving them a large contrast load all in one sitting, albeit hard to know whether they do or not. But spacing that out by just a couple of days would really have a big impact.

Parikh: Very often in the STEMI patient, you don’t have the benefit of knowing the creatinine. The patient will come in immediately, if not directly from the ambulance to the cath lab, and there are no laboratories at all to work with. If the patient has never been seen in the system before, you won’t know. Again, in those situations, one may have pause, particularly if it’s an older patient. I think what’s reassuring, though, is that the data are supportive of being more aggressive earlier, and certainly this is the dataset that we were looking for.

O’Donoghue: To summarize, the two key takeaways are that, one, we now have more data to support a complete revascularization strategy and even extending that now to non-STEMI patients. Two, sooner appears to be better, so ideally, all done at the time of the index procedure. I think this is very interesting science and we’ll see how it changes practice.

AMSTERDAM – For patients hospitalized for acute heart failure, initiating treatment with the SGLT2 inhibitor dapagliflozin (Farxiga, AstraZeneca) before hospital discharge was safe, it appeared to improve diuresis and natriuresis while reducing the administered diuretic dose, and it meant quicker initiation of guideline-directed therapy in a controlled study of 238 patients.

Treatment with dapagliflozin was begun for people with heart failure on their first day of hospitalization for an acute episode. Such treatment “can be safely started to optimize a key medication,” Zachary Cox, PharmD, said at the annual congress of the European Society of Cardiology. It improved fluid removal, as evidenced in the “totality of diuretic measures,” it resulted in reduced doses of IV diuretics, and it shortened length of stay in the hospital.

In current U.S. practice, about 80% of people hospitalized with heart failure do not initially receive treatment with a sodium-glucose cotransporter 2 (SGLT2) inhibitor during their hospital stay when they are not already taking an agent from the class, noted Dr. Cox, professor of pharmacy at Lipscomb University College of Pharmacy in Nashville, Tenn.

Physicians are often uncomfortable changing a patient’s medications on the first day of a hospitalization, he noted. “Our results should embolden physicians” to begin treatment with an SGLT2 inhibitor early during hospitalization and to then continue it chronically, Dr. Cox said in a press briefing.

“Despite the messaging [from guidelines], we still see hesitancy. We hope more evidence of safety will improve uptake.” The study’s “key message is to start guideline-directed medical therapy early,” prior to hospital discharge, Dr. Cox concluded.
 

“Some support” for SGLT2 inhibitors

The study results “provide some support for SGLT2 inhibitors facilitating decongestion and hospital discharge without observed safety issues,” said Stephen D. Wiviott, MD, designated discussant for the report and a cardiologist and professor at Harvard Medical School in Boston.

While initiation of an SGLT2 inhibitor during an acute heart failure hospitalization received endorsement as a top management priority in both the 2023 heart failure guidelines of the European Society of Cardiology and in 2022 U.S. guidelines, evidence of the safety and efficacy of this approach has been scanty, Dr. Wiviott noted.

Two prior studies addressed the issue. The SOLOIST-WHF trial tested the combined SGLT1 and SGLT2 inhibitor sotagliflozin (Inpefa, Lexicon) for patients recently hospitalized for heart failure, but only 142 of the 596 participants who were randomly assigned to receive sotagliflozin began receiving it at least a day before hospital discharge; for the remaining 454, treatment with sotagliflozin began on their discharge day, noted Dr. Wiviott.

In the EMPULSE trial, 530 people hospitalized for acute heart failure were randomly assigned to initially receive empagliflozin (Jardiance, Boehringer Ingelheim and Lilly) or placebo during hospitalization. The primary endpoint was largely driven by an improvement in the patient-reported outcome, as assessed on the basis of the Kansas City Cardiomyopathy Questionnaire Total Symptom Score, Dr. Wiviott added.

The DICTATE-AHF study included 238 adults who were within 24 hours of first presenting to any of six participating U.S. hospitals with hypervolemic acute heart failure. All patients underwent a standard treatment protocol with IV loop diuretics, and half received additional, open-label treatment with a daily 10-mg dose of dapagliflozin.

The average age of the patients was 65 years, 71% had type 2 diabetes (the study excluded people with type 1 diabetes), and about half had a left ventricular ejection fraction of 40% or less.
 

Similar weight loss with lower diuretics dose

The study’s primary outcome was a measure of diuretic efficiency, calculated as a person’s cumulative weight change divided by the cumulative dose of loop diuretics.

Both treatment arms experienced nearly identical weight loss, but for the people who received dapagliflozin, this occurred with a lower cumulative dose of diuretics. The diuretic efficiency with dapagliflozin produced comparable weight loss with a 35% lower amount of loop diuretic dose, a difference that fell just short of significance (P = .06).

However, treatment with dapagliflozin also significantly boosted 24-hour natriuresis and 24-hour diuresis, and it significantly shortened the time to stopping treatment with IV diuretics and to hospital discharge, Dr. Cox reported. Dapagliflozin initiation and ongoing treatment was also safe and well tolerated compared with usual care.

The fact that the primary endpoint fell short of significance was “largely related” to the study’s relatively small size, Dr. Wiviott suggested. He noted that the DAPA ACT HF-TIMI 68 study, which is a much larger and potentially more definitive study of the safety and efficacy of dapagliflozin in comparison with usual care for patients with acute heart failure, is in progress. The study includes about 2,400 patients.

The primary outcome is the combined rate of cardiovascular death or worsening heart failure during the 2 months following randomization. Results are expected in 2024.

AMSTERDAM – For patients hospitalized for acute heart failure, initiating treatment with the SGLT2 inhibitor dapagliflozin (Farxiga, AstraZeneca) before hospital discharge was safe, it appeared to improve diuresis and natriuresis while reducing the administered diuretic dose, and it meant quicker initiation of guideline-directed therapy in a controlled study of 238 patients.

Treatment with dapagliflozin was begun for people with heart failure on their first day of hospitalization for an acute episode. Such treatment “can be safely started to optimize a key medication,” Zachary Cox, PharmD, said at the annual congress of the European Society of Cardiology. It improved fluid removal, as evidenced in the “totality of diuretic measures,” it resulted in reduced doses of IV diuretics, and it shortened length of stay in the hospital.

In current U.S. practice, about 80% of people hospitalized with heart failure do not initially receive treatment with a sodium-glucose cotransporter 2 (SGLT2) inhibitor during their hospital stay when they are not already taking an agent from the class, noted Dr. Cox, professor of pharmacy at Lipscomb University College of Pharmacy in Nashville, Tenn.

Physicians are often uncomfortable changing a patient’s medications on the first day of a hospitalization, he noted. “Our results should embolden physicians” to begin treatment with an SGLT2 inhibitor early during hospitalization and to then continue it chronically, Dr. Cox said in a press briefing.

“Despite the messaging [from guidelines], we still see hesitancy. We hope more evidence of safety will improve uptake.” The study’s “key message is to start guideline-directed medical therapy early,” prior to hospital discharge, Dr. Cox concluded.
 

“Some support” for SGLT2 inhibitors

The study results “provide some support for SGLT2 inhibitors facilitating decongestion and hospital discharge without observed safety issues,” said Stephen D. Wiviott, MD, designated discussant for the report and a cardiologist and professor at Harvard Medical School in Boston.

While initiation of an SGLT2 inhibitor during an acute heart failure hospitalization received endorsement as a top management priority in both the 2023 heart failure guidelines of the European Society of Cardiology and in 2022 U.S. guidelines, evidence of the safety and efficacy of this approach has been scanty, Dr. Wiviott noted.

Two prior studies addressed the issue. The SOLOIST-WHF trial tested the combined SGLT1 and SGLT2 inhibitor sotagliflozin (Inpefa, Lexicon) for patients recently hospitalized for heart failure, but only 142 of the 596 participants who were randomly assigned to receive sotagliflozin began receiving it at least a day before hospital discharge; for the remaining 454, treatment with sotagliflozin began on their discharge day, noted Dr. Wiviott.

In the EMPULSE trial, 530 people hospitalized for acute heart failure were randomly assigned to initially receive empagliflozin (Jardiance, Boehringer Ingelheim and Lilly) or placebo during hospitalization. The primary endpoint was largely driven by an improvement in the patient-reported outcome, as assessed on the basis of the Kansas City Cardiomyopathy Questionnaire Total Symptom Score, Dr. Wiviott added.

AMSTERDAM – A short course of the interleukin-1 receptor antagonist, anakinra, appeared safe but did not reduce complications of acute myocarditis in the ARAMIS trial.

The trial was presented at the annual congress of the European Society of Cardiology.

Lead investigator, Mathieu Kerneis, MD, Pitie Salpetriere APHP University Hospital, Paris, said this was the largest randomized controlled trial of patients with acute myocarditis and probably the first ever study in the acute setting of myocarditis patients diagnosed with cardiac magnetic resonance (CMR) imaging, not on biopsy, who are mostly at low risk for events.

He suggested that one of the reasons for the neutral result could have been the low-risk population involved and the low complication rate. “We enrolled an all-comer acute myocarditis population diagnosed with CMR, who were mostly at a low risk of complications,” he noted.

“I don’t think the story of anti-inflammatory drugs in acute myocarditis is over. This is just the beginning. This was the first trial, and it was just a phase 2 trial. We need further randomized trials to explore the potential benefit of an anti-inflammatory strategy in acute myocarditis patients at higher risk of complications. In addition, larger studies are needed to evaluate prolonged anti-inflammatory strategies in acute myocarditis patients at low-to-moderate risk of complications,” Dr. Kerneis concluded.

“It is very challenging to do a trial in high-risk patients with myocarditis as these patients are quite rare,” he added.
 

Inflammation of the myocardium

Dr. Kerneis explained that acute myocarditis is an inflammation of the myocardium that can cause permanent damage to the heart muscle and lead to myocardial infarction, stroke, heart failure, arrhythmias, and death. The condition can occur in individuals of all ages but is most frequent in young people. There is no specific treatment, but patients are generally treated with beta-blockers, angiotensin-converting enzyme (ACE) inhibitors, and sometimes steroids.

Anakinra is an interleukin-1 receptor antagonist that works by targeting the interleukin-1β innate immune pathway. Anakinra is used for the treatment of rheumatoid arthritis and has shown efficacy in pericarditis. Dr. Kerneis noted that there have been several case reports of successful treatment with anakinra in acute myocarditis.

The ARAMIS trial – conducted at six academic centers in France – was the first randomized study to evaluate inhibition of the interleukin-1β innate immune pathway in myocarditis patients. The trial enrolled 120 hospitalized, symptomatic patients with chest pain, increased cardiac troponin, and acute myocarditis diagnosed using CMR. More than half had had a recent bacterial or viral infection.

Patients were randomized within 72 hours of hospital admission to a daily subcutaneous dose of anakinra 100 mg or placebo until hospital discharge. Patients in both groups received standard-of-care treatments, including an ACE inhibitor, for at least 1 month. Consistent with prior data, the median age of participants was 28 years and 90% were men.

The primary endpoint was the number of days free of myocarditis complications (heart failure requiring hospitalization, chest pain requiring medication, left ventricular ejection fraction less than 50%, and ventricular arrhythmias) within 28 days postdischarge.

There was no significant difference in this endpoint between the two arms, with a median of 30 days for anakinra versus 31 days for placebo.

Overall, the rate of the composite endpoint of myocarditis complications occurred in 13.7% of patients, and there was a numerical reduction in the number of patients with these myocarditis complications with anakinra – 6 patients (10.5%) in the anakinra group versus 10 patients (16.5%) in the placebo group (odds ratio, 0.59; 95% confidence interval, 0.19-1.78). This was driven by fewer patients with chest pain requiring new medication (two patients versus six patients).

The safety endpoint was the number of serious adverse events within 28 days postdischarge. This endpoint occurred in seven patients (12.1%) in the anakinra arm and six patients (10.2%) in the placebo arm, with no significant difference between groups. Cases of severe infection within 28 days postdischarge were reported in both arms.
 

Low-risk population

Designated discussant of the study at the ESC Hotline session, Enrico Ammirati, MD, PhD, University of Milano-Bicocca, Monza, Italy, said that patients involved in ARAMIS fit the profile of acute myocarditis and that the CMR diagnosis was positive in all the patients enrolled.

Dr. Ammirati agreed with Dr. Kerneis that the neutral results of the study were probably caused by the low-risk population. “If we look at retrospective registries, at 30 days there are zero cardiac deaths or heart transplants at 30 days in patients with a low-risk presentation.

“The ARAMIS trial has shown the feasibility of conducting studies in the setting of acute myocarditis, and even if the primary endpoint was neutral, some important data are still missing, such as change in ejection fraction and troponin levels,” he noted.

“In terms of future perspective, we are moving to assessing efficacy of anakinra or other immunosuppressive drugs from acute low risk patients to higher risk patients with heart failure and severe dysfunction,” he said.  

Dr. Ammirati is the lead investigator of another ongoing study in such a higher-risk population; the MYTHS trial is investigating the use of intravenous steroids in patients with suspected acute myocarditis complicated by acute heart failure or cardiogenic shock, and an ejection fraction below 41%.

“So, we will have more results on the best treatment in this higher risk group of patients,” he concluded.

The ARAMIS trial was an academic study funded by the French Health Ministry and coordinated by the ACTION Group. Dr. Kerneis reports having received consulting fees from Kiniksa, Sanofi, and Bayer, and holds a patent for use of abatacept in immune checkpoint inhibitor (ICI)–induced myocarditis.

AMSTERDAM – A simple, low-cost 5-day course of dietary inorganic nitrate has shown apparent overwhelming benefit in preventing contrast-induced nephropathy (CIN) and reducing subsequent renal and cardiovascular outcomes.

In the NITRATE-CIN Study, non-ST segment elevation myocardial infarction acute coronary syndrome (ACS) patients at risk of renal injury from coronary angiography who received dietary inorganic nitrates had a 70% reduction in CIN compared with those given placebo.

The nitrate group also showed an impressive reduction in periprocedural myocardial infarction (MI) and improved renal function at 3 months, as well as a halving of major adverse cardiovascular events and major adverse kidney events at 1 year.

The trial was presented by Dan Jones, MD, Barts Health NHS Trust, London, at the annual congress of the European Society of Cardiology.

“Currently, aside from intravenous hydration, there is no proven treatment that reduces contrast-induced nephropathy. We feel that dietary inorganic nitrate shows huge promise in this study, and these findings could have important implications in reducing this serious complication of coronary angiography,” Dr. Jones concluded.

He explained that the product used was a formulation of dietary inorganic nitrates given as potassium nitrate capsules, which the study investigators produced specifically for this trial.

At this point, “the only way to get inorganic nitrate is in the diet – specifically by consuming beetroot juice or green leafy vegetables such as spinach and rocket. From a clinician perspective, while these results suggest this is an effective therapy and has great potential, it is not currently possible to prescribe the medication we used in our study, although we are working on producing a commercial product,” he said in an interview.

However, Dr. Jones noted that it is possible to buy beetroot shots, which contain 7 mmol of potassium nitrate in each shot, from health food shops and websites, and two such shots per day for 5 days would give a dose similar to that used in this study, starting the day before angiography.

“While we need a larger multicenter study to confirm these results, studies so far suggest no signal at all that there is any harm in this approach, and there could be a great deal of benefit in taking a couple of beetroot shots prior to and for a few days after an angiogram,” he said.
 

Dietary nitrates “make sense”

Designated discussant of the NITRATE-CIN trial at the ESC Hotline session, Roxanna Mehran, MD, Icahn School of Medicine at Mount Sinai, New York, said the study was well designed, and the “interesting and plausible” hypothesis to raise nitric oxide levels by dietary nitrates “makes sense.”

On the main findings of a major significant 50% reduction in acute kidney injury, Dr. Mehran said, “It is difficult to imagine such a reduction is possible.”

She pointed out that the large reduction in major adverse cardiac events and major adverse kidney events at 1 year also suggests that there is a sustained benefit in protecting the kidney.

“We’re all going to get on beet juice after this,” she quipped.

Still, Dr. Mehran questioned whether the results were “too good to be true,” adding that a larger trial actually powered for longer term outcome events is needed, as well as a better understanding of whether CIN has a causative role in mortality.

Responding to questions about whether such a large effect could actually be achieved with dietary nitrates, Dr. Jones said he thought there would definitely be some benefits, but maybe not quite as large as those seen in this study.

“From our pilot data we thought nitrate may be effective in preventing CIN,” he said in an interview. “We recruited a higher risk group than we thought, which is why the control event rates were higher than we expected, but the acute kidney injury reduction is roughly what we had estimated, and makes sense biologically.”

Dr. Jones acknowledged that the large reductions in long-term major adverse cardiovascular and kidney events were unexpected.

“The trial was not powered to see reductions in these outcomes, so we need to see if those event reductions can be replicated in larger multicenter trials,” he said. “But this was a double-blind placebo-controlled trial so in this trial the effects are real, and I think the effect size in this trial is too large for there not to be a beneficial effect.

“But I’m not so sure that we would see the same magnitude of effect when we have a larger study with tighter confidence intervals but perhaps a 20%-25% reduction in cardiovascular and kidney may be more realistic, which would still be amazing for such an easy and cost-effective intervention,” Dr. Jones added.

A larger trial is now being planned.

The researchers are also working on the development of a commercial form of dietary inorganic nitrate that would be needed for larger multicenter studies and would then be generally available. “We want this to be a low-cost product that would be available to all,” Dr. Jones said.

He noted that other studies have shown that dietary inorganic nitrates in the form of beetroot juice lower blood pressure; there are suggestions it may also lower cholesterol and prevent stent restenosis, and athletes sometimes take it to increase their aerobic capacity.

“There appears to be many benefits of dietary nitrates, and the one thing we can do at this time is to encourage people to increase their dietary nitrate consumption by eating large quantities of green leafy vegetables and beetroot,” Dr. Jones said.
 

Replacing lost nitric oxide

In his presentation, Dr. Jones noted that CIN is a serious complication after coronary angiography and is associated with longer hospital stays, worse long-term kidney function, and increased risk of MI and death.

The incidence varies depending on patient risk and definitions used, but it can affect up to 50% of high-risk ACS patients – older patients and/or those with heart failure, chronic kidney disease, or diabetes.

“We don’t really understand the mechanisms that cause CIN, but multiple proposed mechanisms exist, and we know from previous studies that a deficiency of nitric oxide is crucial to the development of CIN,” he explained. “We also know that [nitric oxide] is crucial for normal renal hemostasis. Therefore, a potential therapeutic target to prevent CIN would be to replace this lost nitric oxide.”

The inorganic nitrate evaluated in this trial is found in the diet, is produced endogenously, and is different from medicinally synthesized organic nitrates such as isosorbide mononitrate, he said.

“Isosorbide mononitrate/dinitrate tablets contain organic nitrates and while they are good for angina, we know that they do not have the same beneficial effects on the sustained generation of nitric oxide as inorganic nitrates,” Dr. Jones added.
 

NITRATE-CIN study

NITRATE-CIN was a double-blind, randomized, placebo-controlled trial conducted at Queen Mary University of London and St. Bartholomew’s Hospital in London, which tested the effectiveness of inorganic nitrate in preventing contrast-induced nephropathy in 640 patients with non-ST elevation ACS referred for invasive coronary angiography.

To be eligible for the trial, patients had to be at risk of contrast-induced nephropathy with an estimated glomerular filtration rate (eGFR) less than 60 mL/min per 1.73 m² or have two of the following significant risk factors: diabetes, liver failure, over 70 years of age, exposure to contrast within 7 days, heart failure, or on concomitant renally acting drugs.

Patients were randomly assigned to a formulation of potassium nitrate (12 mmol/744 mg nitrate) per day given as capsules for a 5-day course with the first dose administered prior to angiography or to a control group that received potassium chloride with a matched potassium concentration.

The patient population had a mean age of 71 years, 73% were male, 75% were White, 46% had diabetes, and 56% had chronic kidney disease. There was a 13% loss to follow-up, which was attributed to the COVID pandemic.

The amount of contrast administration was 180 mL in the placebo and 170 mL in the nitrate arm, with 50% of patients undergoing some sort of revascularization.

The primary endpoint was the incidence of CIN as defined by KDIGO criteria – a series of stages of acute kidney injury defined by changes in serum creatinine within 72 hours and up to 1 week.

Results showed that this primary CIN endpoint was reduced significantly from 30% in the placebo arm to 9.1% in the nitrate group, a 70% relative risk reduction (P < .0001). The majority (90%) of this CIN was stage 1, but 10% was stage 2.

Consistent results were seen when an alternative definition of CIN (Mehran) was used, although the rates in both arms were lower than when the KDIGO definition was used.

The benefit was seen across prespecified subgroups including diabetes status, troponin positivity, and Mehran risk. But the benefit seemed to be attenuated in patients on preexisting organic nitrate therapy, although the numbers in these groups were too small to draw definitive conclusions.

As would be expected, there were significant elevations in both systemic nitrate and nitrite levels both up to 72 hours after the procedure, which was consistent with the 5-day course. This was associated with reductions in systolic and diastolic blood pressure, but not associated with any adverse events, Dr. Jones reported.

Rates of procedural MI, a prespecified secondary endpoint, were reduced from 12.5% to 4.1% in those on inorganic nitrates (P = .003).

Looking at longer term outcomes, kidney function was improved at 3 months as measured by change in eGFR, which showed a 10% relative improvement of 5.2 mL/min per 1.73 m² (10%) in the nitrate group vs. the placebo group. Serum creatinine levels were also significantly increased in the nitrate group.

At 12 months, there was a significant 50% relative reduction in major adverse cardiovascular events – including all-cause mortality, recurrent MI, and recurrent revascularization – which were reduced from 18.1% in the placebo group to 9.1% in the nitrate group, with a reduction in all three of the constituent components of the composite endpoint including all-cause mortality.

Major adverse kidney events (all-cause mortality, renal replacement therapy, or persistent renal dysfunction) were also reduced at 12 months from 28.4% in the placebo group to 10.7% in the nitrate group (P < .0001), a 60% relative reduction. This was driven by lower rates of all-cause mortality and persistent renal dysfunction.

While Dr. Jones said these results on major cardiovascular and kidney outcomes should be viewed as hypothesis-generating at the present time, he said there were biological mechanisms that could explain these benefits.

“We saw a reduction in procedural MI, and we know there is a lot of similar biology in preventing procedural MI and subsequent cardiac events in the acute phase. This, in combination with the large reduction in acute kidney injury, could explain why there’s improved outcomes out to 12 months.”

In her comments, Dr. Mehran congratulated the investigators on having conducted the first study to have shown benefit in the prevention of contrast-associated acute kidney injury as well as major adverse cardiovascular and kidney events associated with the condition.

She used the term “contrast-associated acute kidney injury” rather than “contrast-induced nephropathy” because, she said, it has not been proven that the acute kidney injury seen after angiography is actually caused by the contrast and “so many other things are occurring during procedures when these patients are presenting with different syndromes.”

Dr. Mehran pointed out some weaknesses in the NITRATE-CIN study including the single-center design, the large volume of contrast administered, 13% of patients missing the primary endpoint blood draw, and an imbalance in relevant baseline characteristics despite randomization.

The NITRATE-CIN study was funded by Heart Research UK. Dr. Jones has disclosed no relevant financial relationships.

AMSTERDAM – A simple, low-cost 5-day course of dietary inorganic nitrate has shown apparent overwhelming benefit in preventing contrast-induced nephropathy (CIN) and reducing subsequent renal and cardiovascular outcomes.

In the NITRATE-CIN Study, non-ST segment elevation myocardial infarction acute coronary syndrome (ACS) patients at risk of renal injury from coronary angiography who received dietary inorganic nitrates had a 70% reduction in CIN compared with those given placebo.

The nitrate group also showed an impressive reduction in periprocedural myocardial infarction (MI) and improved renal function at 3 months, as well as a halving of major adverse cardiovascular events and major adverse kidney events at 1 year.

The trial was presented by Dan Jones, MD, Barts Health NHS Trust, London, at the annual congress of the European Society of Cardiology.

“Currently, aside from intravenous hydration, there is no proven treatment that reduces contrast-induced nephropathy. We feel that dietary inorganic nitrate shows huge promise in this study, and these findings could have important implications in reducing this serious complication of coronary angiography,” Dr. Jones concluded.

He explained that the product used was a formulation of dietary inorganic nitrates given as potassium nitrate capsules, which the study investigators produced specifically for this trial.

At this point, “the only way to get inorganic nitrate is in the diet – specifically by consuming beetroot juice or green leafy vegetables such as spinach and rocket. From a clinician perspective, while these results suggest this is an effective therapy and has great potential, it is not currently possible to prescribe the medication we used in our study, although we are working on producing a commercial product,” he said in an interview.

However, Dr. Jones noted that it is possible to buy beetroot shots, which contain 7 mmol of potassium nitrate in each shot, from health food shops and websites, and two such shots per day for 5 days would give a dose similar to that used in this study, starting the day before angiography.

“While we need a larger multicenter study to confirm these results, studies so far suggest no signal at all that there is any harm in this approach, and there could be a great deal of benefit in taking a couple of beetroot shots prior to and for a few days after an angiogram,” he said.
 

Dietary nitrates “make sense”

Designated discussant of the NITRATE-CIN trial at the ESC Hotline session, Roxanna Mehran, MD, Icahn School of Medicine at Mount Sinai, New York, said the study was well designed, and the “interesting and plausible” hypothesis to raise nitric oxide levels by dietary nitrates “makes sense.”

On the main findings of a major significant 50% reduction in acute kidney injury, Dr. Mehran said, “It is difficult to imagine such a reduction is possible.”

She pointed out that the large reduction in major adverse cardiac events and major adverse kidney events at 1 year also suggests that there is a sustained benefit in protecting the kidney.

“We’re all going to get on beet juice after this,” she quipped.

Still, Dr. Mehran questioned whether the results were “too good to be true,” adding that a larger trial actually powered for longer term outcome events is needed, as well as a better understanding of whether CIN has a causative role in mortality.
