More than half of patients taking the two highest doses of tirzepatide as a once-weekly injection lost at least 20% of their body weight in the first phase 3 trial to examine this agent in patients with obesity, but without diabetes, according to preliminary top-line results from the SURMOUNT-1 trial announced by Lilly.  

The full results will be reported at an upcoming medical conference and published at a later date, Lilly added.

There was much excitement in response to the news, but others have urged caution and noted that, even if tirzepatide is eventually approved for obesity, one of the major barriers to use in the United States will be insurance coverage.

“Wow (and a double Wow!) 52lb weight loss (22.5%) at highest dose of tirzepatide,” tweeted Sek Kathiresan, MD, a cardiologist who is cofounder of Verve Therapeutics and on leave from Harvard (@skathire).

“Thus far the challenge with GLP-1s [agonists] for management of obesity is that insurance usually isn’t covering them. This makes them unaffordable for most people,” replied James Marroquin, MD, of the University of Texas at Austin. (@Jamesmarroquin).

Yoni Freedhoff, MD, of the University of Ottawa (Ont.) who writes a column for this news organization on obesity, said if tirzepatide pans out, along with other similar agents already on the market for this indication, “the next few decades should see the pharmaceutical management of obesity rival its surgical management.”

Would compete with ‘game-changer’ semaglutide?

Tirzepatide has been dubbed a “twincretin” because it works not only as an agonist of the glucagonlike peptide-1 (GLP-1) receptor, but also of the glucose-dependent insulinotropic polypeptide (GIP) receptor. It has been much hyped based on the results of the series of SURPASS clinical trials, which have formed the basis of the application for type 2 diabetes approval, about which the U.S. Food and Drug Administration is expected to make a decision soon.

Several GLP-1 agonists are on the market for both type 2 diabetes and for obesity indications separately, including semaglutide (marketed as Wegovy for obesity, also a once-weekly injection) and liraglutide (Saxenda for obesity, a daily injection), both Novo Nordisk agents.

Wegovy was approved for weight loss in the United States last year, with doctors telling this news organization then that a third of patients who take the drug are likely to lose 20% or more of their starting weight, an outcome that approaches reductions seen with bariatric surgery.

Dr. Freedhoff said he’d like to see “reimbursement by insurers who will see these drugs serving as important ancillary treatments for the myriad of weight-responsive conditions they’re already covering.”

SURMOUNT-1 data: ‘Impressive body weight’ reductions

The new tirzepatide data come from the multicenter, randomized, double-blind, placebo-controlled SURMOUNT-1 trial, which included 2539 participants from the United States, Argentina, Brazil, China, India, Japan Mexico, Russia, and Taiwan. They had obesity or overweight plus at least one comorbidity but not diabetes. They were randomized to 5-mg, 10-mg, or 15-mg once-weekly tirzepatide or placebo injections for 18 months (72 weeks).

Efficacy was analyzed in two ways. Prior to factoring in drug discontinuation, participants taking tirzepatide experienced weight loss of 16.0% (35 lb/16 kg) with 5 mg, 21.4% (49 lb/22 kg) with 10 mg, and 22.5% (52 lb/24 kg) on 15 mg. In contrast, the placebo group lost just 2.4% of body weight (5 lb/2 kg).  

But treatment discontinuation rates because of adverse events were 4.3%, 7.1%, 6.2%, and 2.6%, for tirzepatide 5 mg, 10 mg, 15 mg, and placebo, respectively. Overall treatment discontinuation rates were 14.3%, 16.4%, 15.1%, and 26.4%, respectively.  

When efficacy was assessed regardless of treatment discontinuation, average body weight reductions were 15.0%, 19.5%, 20.9%, and 3.1% for tirzepatide 5 mg, 10 mg, 15 mg, and placebo, respectively.  

More than half of patients taking tirzepatide 10 mg and 15 mg (55% and 63%, respectively) lost at least 20% of their body weight, compared with just 1.3% taking placebo.

Overall safety and tolerability were similar to those of other GLP-1 agonists, with adverse events being gastrointestinal in nature and increasing with higher doses. Nausea affected 24.6%, 33.3%, and 31.0% of the tirzepatide 5-mg, 10-mg, and 15-mg dose groups, respectively, and vomiting was experienced by 8.3%, 10.7%, and 12.2% of patients, respectively. Diarrhea and constipation were also reported more often with the drug than placebo.

“Tirzepatide delivered impressive body weight reductions in SURMOUNT-1, which could represent an important step forward for helping the patient and physician partnership treat this complex disease,” said study investigator Louis J. Aronne, MD, director of the Comprehensive Weight Control Center and the Sanford I. Weill Professor of Metabolic Research at Weill Cornell Medicine, New York, in a press release.

Further studies are ongoing for tirzepatide as a potential treatment for obesity or overweight, according to the Lilly statement. SURMOUNT is a phase 3 global clinical development program for tirzepatide that began in late 2019 with over 5,000 people with obesity or overweight across six clinical trials. Results from SURMOUNT-2, SURMOUNT-3, and SURMOUNT-4 are expected in 2023.

Tirzepatide is also being studied as a potential treatment for nonalcoholic fatty liver disease and heart failure with preserved ejection fraction. Studies of tirzepatide in obstructive sleep apnea and of morbidity/mortality in obesity are also planned.

Dr. Aronne is cofounder, chief scientific advisor, and a member of the board of directors for Intellihealth. He is also a paid scientific advisory board member for Eli Lilly. Dr. Freedhoff has served or is serving as a director, officer, partner, employee, adviser, consultant, or trustee for the Bariatric Medical Institute and Constant Health and has received a research grant from Novo Nordisk.

Deaths from COVID-19 may have caught more attention lately, but heart disease remains the leading cause of death in the United States.

More than 300,000 Americans will die this year of sudden cardiac arrest (also called sudden cardiac death, or SCD), when the heart abruptly stops working.

These events happen suddenly and often without warning, making them nearly impossible to predict. But that may be changing, thanks to 3D imaging and artificial intelligence (AI) technology under study at Johns Hopkins University, Baltimore.

Svisio/Thinkstock

There, researchers are working to create more accurate and personalized models of the heart – and not just any heart, your heart, if you have heart disease.

“Right now, a clinician can only say whether a patient is at risk or not at risk for sudden death,” says Dan Popescu, PhD, a Johns Hopkins research scientist and first author of a new study on AI’s ability to predict sudden cardiac arrest. “With this new technology, you can have much more nuanced predictions of probability of an event over time.”

Put another way: With AI, clinicians may be able not only to predict if someone is at risk for sudden cardiac arrest, but also when it is most likely to happen. They can do this using a much clearer and more personalized look at the electrical “wiring” of your heart.
 

Your heart, the conductor

Your heart isn’t just a metronome responsible for keeping a steady stream of blood pumping to tissues with every beat. It’s also a conductor through which vital energy flows.

To make the heart beat, electrical impulses flow from the top to the bottom of the organ. Healthy heart cells relay this electricity seamlessly. But in a heart damaged by inflammation or a past heart attack, scar tissue will block the energy flow.

When an electrical impulse encounters a scarred area, the signal can become erratic, disrupting the set top-to-bottom path and causing irregular heartbeats (arrhythmias), which increase someone’s danger of sudden cardiac death.
 

Seeing the heart in 3D

Today’s tests offer some insights into the heart’s makeup. For example, MRI scans can reveal damaged areas. PET scans can show inflammation. And EKGs can record the heart’s electrical signals from beat to beat.

But all these technologies offer only a snapshot, showing heart health at a moment in time. They can’t predict the future. That’s why scientists at Johns Hopkins are going further to develop 3D digital replicas of a person’s heart, known as computational heart models.

Computational models are computer-simulated replicas that combine mathematics, physics, and computer science. These models have been around for a long time and are used in many fields, ranging from manufacturing to economics.

In heart medicine, these models are populated with digital “cells,” which imitate living cells and can be programmed with different electrical properties, depending on whether they are healthy or diseased.

“Currently available imaging and testing (MRIs, PETs, EKGs) give some representation of the scarring, but you cannot translate that to what is going to happen over time,” says Natalia Trayanova, PhD, of the Johns Hopkins department of biomedical engineering.

“With computational heart models, we create a dynamic digital image of the heart. We can then give the digital image an electrical stimulus and assess how the heart is able to respond. Then you can better predict what is going to happen.”

The computerized 3D models also mean better, more accurate treatment for heart conditions.

For example, a common treatment for a type of arrhythmia known as atrial fibrillation is ablation, or burning some heart tissue. Ablation stops the erratic electrical impulses causing the arrhythmia, but it can also damage otherwise healthy heart cells.

A personalized computational heart model could allow doctors to see more accurately what areas should and shouldn’t be treated for a specific patient.
 

Using deep learning AI to predict health outcomes

Dr. Trayanova’s colleague Dr. Popescu is applying deep learning and AI to do more with computerized heart models to predict the future.

In a recent paper in Nature Cardiovascular Research, the research team showed their algorithm assessed the health of 269 patients and was able to predict the chance of sudden cardiac arrest up to 10 years in advance.

“This is really the first time ever, as far as we know, where deep learning technology has been proven to analyze scarring of the heart in a successful way,” Dr. Popescu says.

Dr. Popescu and Dr. Trayanova say the AI algorithm gathers information from the 3D computational heart models with patient data like MRIs, ethnicity, age, lifestyle, and other clinical information. Analyzing all these data can produce accurate and consistent estimates about how long patients might live if they are at risk for sudden death.

“You can’t afford to be wrong. If you are wrong, you can actually impact a patient’s quality of life dramatically,” Dr. Popescu says. “Having clinicians use this technology in the decision-making process will provide confidence in a better diagnosis and prognosis.”

While the current study was specifically about patients with a particular type of heart disease, Dr. Popescu says his algorithm can also be trained to assess other health conditions.

So when might you see this being used outside of a research study? Dr. Trayanova predicts 3D imaging of heart models could be available in 2 years, but first the technique must be tested in more clinical trials – some of which are happening right now.

Adding AI to the heart models will require more studies and Food and Drug Administration approval, so the timeline is less clear. But perhaps the biggest hurdle is that after approval the technologies would need to be adopted and used by clinicians and caregivers.

“The much harder question to answer is, ‘When will doctors be perfectly comfortable with AI tools?’ And I don’t know the answer,” Dr. Popescu says. “How to use AI as an aid in the decision-making process is something that’s not currently taught.”

Using deep learning AI to predict health outcomes

Dr. Trayanova’s colleague Dr. Popescu is applying deep learning and AI to do more with computerized heart models to predict the future.

In a recent paper in Nature Cardiovascular Research, the research team showed their algorithm assessed the health of 269 patients and was able to predict the chance of sudden cardiac arrest up to 10 years in advance.

“This is really the first time ever, as far as we know, where deep learning technology has been proven to analyze scarring of the heart in a successful way,” Dr. Popescu says.

Dr. Popescu and Dr. Trayanova say the AI algorithm gathers information from the 3D computational heart models with patient data like MRIs, ethnicity, age, lifestyle, and other clinical information. Analyzing all these data can produce accurate and consistent estimates about how long patients might live if they are at risk for sudden death.

“You can’t afford to be wrong. If you are wrong, you can actually impact a patient’s quality of life dramatically,” Dr. Popescu says. “Having clinicians use this technology in the decision-making process will provide confidence in a better diagnosis and prognosis.”

While the current study was specifically about patients with a particular type of heart disease, Dr. Popescu says his algorithm can also be trained to assess other health conditions.

So when might you see this being used outside of a research study? Dr. Trayanova predicts 3D imaging of heart models could be available in 2 years, but first the technique must be tested in more clinical trials – some of which are happening right now.

Adding AI to the heart models will require more studies and Food and Drug Administration approval, so the timeline is less clear. But perhaps the biggest hurdle is that after approval the technologies would need to be adopted and used by clinicians and caregivers.

“The much harder question to answer is, ‘When will doctors be perfectly comfortable with AI tools?’ And I don’t know the answer,” Dr. Popescu says. “How to use AI as an aid in the decision-making process is something that’s not currently taught.”

Pfizer is voluntarily recalling five lots of Accupril (quinapril HCI) due to unacceptable levels of a nitrosamine, N-nitroso-quinapril, a potential carcinogen, the company announced.

The Accupril recall comes one month after Pfizer recalled six lots of Accuretic (Quinapril HCI/hydrochlorathiazide) tablets for the same problem.

Accupril is indicated for the treatment of hypertension and management of heart failure when added to conventional therapy, including diuretics and/or digitalis.

To date, Pfizer is not aware of any reports of adverse events related to the Accupril recall, and the company believes the benefit/risk profile remains positive based on currently available data.

“Although long-term ingestion of N-nitroso-quinapril may be associated with a potential increased cancer risk in humans, there is no immediate risk to patients taking this medication,” the company said April 22 in a news release.

Patients currently taking the recalled products are asked to consult with their doctor about alternative treatment options.

The recalled Accupril tablets were sold in 90-count bottles distributed nationwide to wholesalers and distributors in the United States and Puerto Rico from December 2019 to April 2022. 

National drug codes (NDC), lot numbers, and expiration dates are listed in the company announcement posted on the Food and Drug Administration’s website.

Patients who are taking this product should consult with their health care provider or pharmacy to determine if they have the affected product. Those with the affected tablets should contact claims management firm Sedgwick by phone at 888-345-0481 Monday through Friday from 8 AM to 5 PM ET for instructions on how to return the product and obtain reimbursement.

Healthcare providers with questions regarding the recall can contact Pfizer by telephone at 800-438-1985, option 3, Monday through Friday from 8 AM to 9 PM ET.

Adverse reactions or quality problems related to this recall should be reported to the FDA’s MedWatch program.

Using the 2021 Kidney Disease: Improving Global Outcomes (KDIGO) guideline target of systolic blood pressure (BP) < 120 mm Hg, 66% of adults with chronic kidney disease (CKD) would be eligible for BP lowering, according to a study from Korea.

This represents an added > 10% of patients compared with two earlier guidelines, and these patients have a high risk of cardiovascular disease (CVD), Hyeok-Hee Lee, MD, Yonsei University College of Medicine, Seoul, South Korea, and colleagues reported.

London_England/Thinkstock

The study was published online  in the Journal of the American College of Cardiology.

“New candidates for BP-lowering treatment per the 2021 KDIGO guideline account for a substantial proportion of the total CKD population and bear significantly high CVD risk,” the researchers concluded.

“Undoubtedly, a multipronged approach will be required to address the swelling number of people needing more intense treatment, especially against a background of falling rates of BP control in the general community,” Alexander G. Logan, MD, of Mount Sinai Hospital, Toronto, and the University of Toronto, wrote in an accompanying editorial.

“Let’s not forget hypertension is the number one killer today,” Valentin Fuster, MD, of Icahn School of Medicine at Mount Sinai, New York, who is editor-in-chief of the Journal of the American College of Cardiology, stressed in a podcast that accompanied the article.

“Only 50% of individuals know of their blood pressure, and from this, less than half are properly treated,” he said.

“Today the details of knowing blood pressure levels appear to dominate over the huge ignorance of not knowing about blood pressure at all. Let’s think more and more about this reality,” he urged.
 

Three guidelines, two study objectives

The researchers compared three guidelines:

• The 2021 KDIGO guidelines, with a target systolic BP of < 120 mm Hg (largely based on the SPRINT trial).
• The 2012 KDIGO guidelines, with a target BP of ≤ 130/80 mm Hg for patients with albuminuria and ≤ 140/90 mm Hg for patients without albuminuria.
• The 2017 American College of Cardiology/American Heart Association (ACC/AHA) BP guideline target of < 130/80 mm Hg.

The study had two objectives:

• To examine the proportions of concordance and discordance between the three guidelines among adults with CKD based on cross-sectional data from the Korea National Health and Nutrition Examination Survey (KNHANES).
• To evaluate the association of each concordance/discordance group with cardiovascular outcomes of patients in the Korean National Health Insurance Service (NHIS) database.

For the first objective, the researchers identified 1,939 adults with CKD from the 2011-2014 survey cycles of KNHANES. Patients were a median age of 59 and 51% were men.

Comparison of the KDIGO 2021 versus 2012 BP targets showed that 50% of patients had BP above both targets; 16% had BP above the KDIGO 2021 target only; 4% had BP above the KDIGO 2012 target only; and 30% had BP control within both targets.

Comparison of the KDIGO 2021 versus 2017 ACC/AHA BP targets showed that 55% of patients had BP above both targets; 11% had BP above the KDIGO 2021 target only; 5% had BP above the 2017 ACC/AHA target only; and 29% had BP control within both targets.

For the second objective, using the NHIS database, researchers identified 412,167 adults with CKD who had routine health examinations during 2009 and 2010. The patients were a median age of 65 and 44% were men.

During a median follow-up of 10 years, the patients had 37,912 incident CVD events, defined as the first hospitalization for myocardial infarction, stroke, or heart failure, or death from CVD.

The adjusted risk of a composite CVD event was higher in patients with BP above the 2021 KDIGO target only (HR, 1.28) or above both the 2012 and 2021 KDIGO targets (HR, 1.52), compared to patients who had BP within both targets.

The adjusted risk of a composite CVD event was also higher in patients with BP above the 2021 KDIGO target only (HR, 1.18) or above both the 2021 KDIGO target and the 2017 ACC/AHA target (HR, 1.41), compared with patients who had BP within both targets.
 

Editorialist highlights three study aspects

Dr. Fuster noted three main points made by Dr. Logan.

First, the KDIGO 2021 guideline is based on office blood pressure, measured according to the procedure used in the 2017 ACC/AHA guideline. However, the SPRINT ambulatory BP ancillary study found that daytime ambulatory systolic BP was 6.8 mm Hg higher in the < 120 mm Hg group than clinic systolic BP that was measured with an automated BP device, mostly without study personnel.

Second, Dr. Logan noted that “not surprisingly, the investigators showed that the weighted proportion of adults with CKD eligible for BP lowering was highest (66.1%) according to 2021 KDIGO guideline,” compared with the two earlier guidelines.

The findings by Dr. Lee and colleagues align with those of a study that used data from the 2015-2018 U.S. NHANES to estimate the proportion of U.S. adults with CKD eligible for BP lowering according to the 2021 KDIGO guidelines, Dr. Logan added. The study found that 69% of U.S. adults (roughly 24.5 million) should correct their BP.

Third, the study in Korea showed a small percentage of patients (3%-5% of the total) had elevated diastolic BP but controlled systolic BP (< 120 mm Hg) with no increased risk of CVD compared to a reference group of patients with well-controlled BP.

“There is a paucity of evidence examining the relationship between diastolic hypertension and outcomes independently from systolic BP level in CKD patients,” Dr. Logan wrote. Similarly, Dr. Lee and colleagues identified this as an area for further research.

One of the largest studies to date on myocarditis after COVID-19 vaccination confirms an increased risk with both the Pfizer and Moderna vaccines in young men and shows that the risk is higher with the Moderna than with the Pfizer vaccine.

The study also suggests for the first time that in young men 16 to 24 years of age, the risk for myocarditis after vaccination with either the Pfizer or Moderna vaccine is higher than the risk for myocarditis after COVID-19 infection.

The population-based study involved data on 23.1 million residents across four Scandinavian countries – Denmark, Finland, Norway, and Sweden – 74% of whom had received two vaccine doses and 7% of whom had received one dose.

By linking data from high-quality nationwide health registers on COVID-19 vaccination, infection rates, and myocarditis diagnoses, the researchers were able to evaluate the risk for myocarditis by vaccine product, vaccination dose number, sex, and age.

The study was published online in JAMA Cardiology.

The results confirm that the risk for myocarditis after COVID-19 mRNA vaccines is highest in young men 16 to 24 years of age after the second dose.

For men in this age group who received two doses of the same vaccine, data were compatible, with between four and seven excess myocarditis events in 28 days per 100,000 individuals after the second dose of the Pfizer vaccine, and between nine and 28 per 100,000 individuals after the second dose of the Moderna vaccine.

“This is one of the largest studies on this topic to date. The first population studies were in Israel, with 5 million individuals, and looked at just the Pfizer vaccine. We have data on 23 million people from Scandinavia that include both the Pfizer and Moderna vaccines,” senior author Rickard Ljung, MD, Swedish Medical Products Agency, told this news organization.

“We show a clearly higher risk of myocarditis after the Moderna vaccine than after the Pfizer vaccine. This has been suggested before, but our data confirm definitively that the Moderna vaccine has a higher risk of myocarditis than the Pfizer vaccine,” he added.

“In the group at highest risk of myocarditis after COVID vaccination – young men aged 16 to 24 – the Pfizer vaccine shows a five times higher risk of myocarditis versus the unvaccinated cohort, while the Moderna vaccine shows a 15 times higher risk,” Dr. Ljung noted.

After seeing these data, the Swedish regulatory authority is no longer recommending use of the Moderna vaccine for people younger than 30 years, Dr. Ljung said. Similar recommendations have been made in Norway and Finland.

The researchers report that their finding of a higher risk for myocarditis after the Moderna vaccine than after the Pfizer vaccine in young men is in line with data from the Canada, France, the United Kingdom, and the United States. But they point out that, compared with previous studies, the current study had the advantage of data analyzed according to a common protocol from four different countries and that showed similar directions of associations, despite considerable differences in previous COVID-19 infection levels and lockdown policies.

Risk higher with vaccination than infection?

For what is believed to be the first time, the Scandinavian data also suggest a higher risk for myocarditis after COVID-19 vaccination with both the Pfizer and Moderna vaccines than after COVID-19 infection in young men 16 to 24 years.

Although previous studies have shown that males in this age group have the highest risk for myocarditis after vaccination, it has always been suggested that the risk after vaccination is lower than the risk after infection. The Scandinavian data suggest otherwise for this age group.

Dr. Ljung explained that the myocarditis risk after COVID infection is very hard to study.

“It is highly dependent on the testing strategy,” he said. “For example, in the first half of 2020, the only people being tested were those admitted to hospital, so studies would have included the sickest patients and would therefore likely have found a higher rate of myocarditis. But this current Scandinavian dataset only included individuals with a positive COVID test after August 2020, reflecting a broader range of people.”

The researchers found an excess rate of myocarditis of 3.26 per 100,000 individuals within 28 days of a positive COVID-19 test among all males, and 1.37 per 100,000 individuals among males 16 to 24 years of age.

“We show that the risk of myocarditis after COVID infection is lower in younger people and higher in older people, but the opposite is true after COVID vaccination, where the risk of myocarditis is higher in younger people and lower in older people,” Dr. Ljung said.

The study was not able to look at severity of myocarditis but did record length of hospital stay, which was similar in patients who developed myocarditis after vaccination and those in the unvaccinated cohort (4 to 5 days). Deaths were rare, with no deaths in people younger than 40 years.

“I think we can say that in people aged over 40, the risk of myocarditis is greater with infection than with vaccination, but in those under 40, it is not so clear. And our data suggest that for young men aged 16 to 24 years, the risk of myocarditis after COVID vaccination with either the Pfizer or Moderna vaccine is higher than after COVID infection,” Dr. Ljung commented.

Although the Swedish regulatory agency has already stopped recommending use of Moderna vaccine in those younger than 30 years on the basis of these data, Dr. Ljung was reluctant to make any recommendations regarding the use of the Pfizer vaccine in young males, saying it was up to individual public-health agencies to makes these decisions. 

But he pointed out that the current study only looked at myocarditis, and COVID infection can result in many other complications that can lead to hospitalization and death, which needs to be taken into account when assessing the risk and benefit of vaccination.

Dr. Ljung noted that the current data only applied to the first two doses of the vaccines; data after booster injections have not been included, although the researchers are looking at that now.

What to advise patients?

In an accompanying Editor’s Note, Ann Marie Navar, MD, University of Texas Southwestern Medical Center, Dallas, who is editor of JAMA Cardiology, and Robert Bonow, MD, Northwestern University Feinberg School of Medicine, Chicago, who is deputy editor of JAMA Cardiology, try to explain how these data can inform the way health care professionals communicate with their patients about vaccination.

They point out the “good news,” that older adults who are at highest risk for COVID-19 complications appear to be at extremely low risk for vaccine-associated myocarditis.

They note that for both men and women older than 40 years, the excess number of cases of myocarditis after vaccination was fewer than two in 100,000 vaccinees across all vaccines studied, and the death toll from COVID-19 in the United States as of March was more than 200 per 100,000 population.

“Given the high rates of morbidity and mortality from COVID-19 infection in older adults and the efficacy of the vaccine in preventing severe infection and death, the benefits of immunization in those older than 40 years clearly outweigh the risks,” the editors say.

But given these data in young men, they suggest that health care professionals consider recommending the Pfizer vaccine over the Moderna vaccine for certain populations, including young men and other individuals for whom concerns about myocarditis present a barrier to immunization.

The editors also point out that although the risk for myocarditis after COVID-19 immunization is real, this low risk must be considered in the context of the overall benefit of the vaccine.

“At the individual level, immunization prevents not only COVID-19-related myocarditis but also severe disease, hospitalization, long-term complications after COVID-19 infection, and death. At the population level, immunization helps to decrease community spread, decrease the chances of new variants emerging, protect people who are immunocompromised, and ensure our health care system can continue to provide for our communities,” they conclude.

One of the largest studies to date on myocarditis after COVID-19 vaccination confirms an increased risk with both the Pfizer and Moderna vaccines in young men and shows that the risk is higher with the Moderna than with the Pfizer vaccine.

The study also suggests for the first time that in young men 16 to 24 years of age, the risk for myocarditis after vaccination with either the Pfizer or Moderna vaccine is higher than the risk for myocarditis after COVID-19 infection.

The population-based study involved data on 23.1 million residents across four Scandinavian countries – Denmark, Finland, Norway, and Sweden – 74% of whom had received two vaccine doses and 7% of whom had received one dose.

By linking data from high-quality nationwide health registers on COVID-19 vaccination, infection rates, and myocarditis diagnoses, the researchers were able to evaluate the risk for myocarditis by vaccine product, vaccination dose number, sex, and age.

The study was published online in JAMA Cardiology.

The results confirm that the risk for myocarditis after COVID-19 mRNA vaccines is highest in young men 16 to 24 years of age after the second dose.

For men in this age group who received two doses of the same vaccine, data were compatible, with between four and seven excess myocarditis events in 28 days per 100,000 individuals after the second dose of the Pfizer vaccine, and between nine and 28 per 100,000 individuals after the second dose of the Moderna vaccine.

“This is one of the largest studies on this topic to date. The first population studies were in Israel, with 5 million individuals, and looked at just the Pfizer vaccine. We have data on 23 million people from Scandinavia that include both the Pfizer and Moderna vaccines,” senior author Rickard Ljung, MD, Swedish Medical Products Agency, told this news organization.

“We show a clearly higher risk of myocarditis after the Moderna vaccine than after the Pfizer vaccine. This has been suggested before, but our data confirm definitively that the Moderna vaccine has a higher risk of myocarditis than the Pfizer vaccine,” he added.

“In the group at highest risk of myocarditis after COVID vaccination – young men aged 16 to 24 – the Pfizer vaccine shows a five times higher risk of myocarditis versus the unvaccinated cohort, while the Moderna vaccine shows a 15 times higher risk,” Dr. Ljung noted.

After seeing these data, the Swedish regulatory authority is no longer recommending use of the Moderna vaccine for people younger than 30 years, Dr. Ljung said. Similar recommendations have been made in Norway and Finland.

The researchers report that their finding of a higher risk for myocarditis after the Moderna vaccine than after the Pfizer vaccine in young men is in line with data from the Canada, France, the United Kingdom, and the United States. But they point out that, compared with previous studies, the current study had the advantage of data analyzed according to a common protocol from four different countries and that showed similar directions of associations, despite considerable differences in previous COVID-19 infection levels and lockdown policies.

Risk higher with vaccination than infection?

For what is believed to be the first time, the Scandinavian data also suggest a higher risk for myocarditis after COVID-19 vaccination with both the Pfizer and Moderna vaccines than after COVID-19 infection in young men 16 to 24 years.

Although previous studies have shown that males in this age group have the highest risk for myocarditis after vaccination, it has always been suggested that the risk after vaccination is lower than the risk after infection. The Scandinavian data suggest otherwise for this age group.

Dr. Ljung explained that the myocarditis risk after COVID infection is very hard to study.

“It is highly dependent on the testing strategy,” he said. “For example, in the first half of 2020, the only people being tested were those admitted to hospital, so studies would have included the sickest patients and would therefore likely have found a higher rate of myocarditis. But this current Scandinavian dataset only included individuals with a positive COVID test after August 2020, reflecting a broader range of people.”

The researchers found an excess rate of myocarditis of 3.26 per 100,000 individuals within 28 days of a positive COVID-19 test among all males, and 1.37 per 100,000 individuals among males 16 to 24 years of age.

“We show that the risk of myocarditis after COVID infection is lower in younger people and higher in older people, but the opposite is true after COVID vaccination, where the risk of myocarditis is higher in younger people and lower in older people,” Dr. Ljung said.

The study was not able to look at severity of myocarditis but did record length of hospital stay, which was similar in patients who developed myocarditis after vaccination and those in the unvaccinated cohort (4 to 5 days). Deaths were rare, with no deaths in people younger than 40 years.

“I think we can say that in people aged over 40, the risk of myocarditis is greater with infection than with vaccination, but in those under 40, it is not so clear. And our data suggest that for young men aged 16 to 24 years, the risk of myocarditis after COVID vaccination with either the Pfizer or Moderna vaccine is higher than after COVID infection,” Dr. Ljung commented.

Although the Swedish regulatory agency has already stopped recommending use of Moderna vaccine in those younger than 30 years on the basis of these data, Dr. Ljung was reluctant to make any recommendations regarding the use of the Pfizer vaccine in young males, saying it was up to individual public-health agencies to makes these decisions. 

But he pointed out that the current study only looked at myocarditis, and COVID infection can result in many other complications that can lead to hospitalization and death, which needs to be taken into account when assessing the risk and benefit of vaccination.

Dr. Ljung noted that the current data only applied to the first two doses of the vaccines; data after booster injections have not been included, although the researchers are looking at that now.

Bariatric surgery can reduce the risk of long-term cardiovascular outcomes in older Medicare beneficiaries with obesity, a large new observational study in which a third of the patients were over age 65 years suggests.

Overall, patients who underwent bariatric surgery had 37% lower all-cause mortality and were significantly less likely to have admissions for new-onset heart failure (64% risk reduction), myocardial infarction (37% risk reduction), and ischemic stroke (29% risk reduction), compared with similar patients who received more conservative treatment, after a median of 4 years of follow-up, report Amgad Mentias, MD, MS, a clinical cardiologist at the Cleveland Clinic Foundation, Ohio, and colleagues.

The results were published in the Journal of the American College of Cardiology.

Previous studies on bariatric surgery outcomes have primarily focused on individuals from select health care networks or medical facilities with restricted coverage in the United States or on patients with diabetes, noted Tiffany M. Powell-Wiley, MD, MPH, of the National Institutes of Health’s National Heart, Lung, and Blood Institute, Bethesda, Maryland, and colleagues in an accompanying editorial.

Contemporary cohort of patients

“A lot of the studies showed long-term outcomes outside of the U.S., specifically in Europe,” Dr. Mentias added.

The aim of this study was to evaluate the long-term association between bariatric surgery and risk of adverse cardiovascular outcomes in a contemporary large cohort from the United States.

Older patients (> 65 years) and those without diabetes were looked at as specific subgroups.

The researchers assessed 189,770 patients. There were 94,885 matched patients in each cohort. Mean age was 62.33 years. Female patients comprised 70% of the cohort. The study group had an average BMI of 44.7 kg/m2.

The study cohort was matched 1:1. Participants were either part of a control group with obesity or a group of Medicare beneficiaries who had bariatric surgery between 2013 and 2019. Sex, propensity score matching on 87 clinical variables, age, and BMI were used to match patients.

Myocardial infarction, new-onset heart failure, ischemic stroke, and all-cause mortality were all study outcomes. As a sensitivity analysis, the study team conducted an instrumental variable assessment.

More specifically, the findings showed that bariatric surgery was linked with the following after a median follow-up of 4.0 years:

• Myocardial infarction (hazard ratio, 0.63; 95% confidence interval, 0.59-0.68)
• Stroke (HR, 0.71; 95% CI, 0.65-0.79)
• New-onset heart failure (HR, 0.46; 95% CI, 0.44-0.49)
• Reduced risk of death (9.2 vs. 14.7 per 1000 person-years; HR, 0.63; 95% CI, 0.60-0.66)

Findings for those over the age of 65 were similar – lower risks of all-cause mortality (HR, 0.64), new-onset heart failure (HR, 0.52), myocardial infarction (HR, 0.70), and stroke (HR, 0.76; all P < .001). Similar findings were shown in subgroup analyses in men and women and in patients with and without diabetes.

The study cohort primarily consisted of Medicare patients, which limits the generalizability of the data. Lack of data on medications taken for cardiovascular and weight loss purposes and potential coding errors because the information was gathered from an administrative database were all limitations of the study, the researchers note.

An additional limitation was that residual unmeasured confounders, particularly patient-focused physical, social, and mental support factors, could play a role in whether a patient opted to have bariatric surgery, the study authors note.

“Additional studies are needed to compare cardiovascular outcomes after bariatric surgery with weight loss medications like glucagon-like peptide-1 (GLP-1) analogues,” the researchers add.

This study was partially funded by philanthropic contributions by the Khouri family, Bailey family, and Haslam family to the Cleveland Clinic for co-author Dr. Milind Y. Desai’s research. Dr. Mentias has disclosed no relevant financial relationships. Dr. Powell-Wiley disclosed relationships with the National Institute on Minority Health and Health Disparities and the Division of Intramural Research of the National, Heart, Lung, and Blood Institute of the National Institutes of Health.

WASHINGTON – Patients with type 2 diabetes and established atherosclerotic cardiovascular disease treated with both an sodium-glucose transporter 2 inhibitor and a glucagonlike peptide–1 receptor agonist had a significant 80% cut in their rate of all-cause death during 1-year follow-up, compared with matched patients treated with an agent from either class alone in an observational, retrospective study of more than 15,000 people in the U.S. Veterans Affairs health system.

For the study’s primary endpoint, the combined rate of all-cause death, nonfatal MI, or nonfatal stroke, combined treatment with both an agent from the sodium-glucose transporter 2 (SGLT2) inhibitor class and from the glucagonlike peptide–1 receptor agonist (GLP-1 RA) class linked with a significant, roughly 50% cut in events during 1-year follow-up, compared with patients treated with an agent from just one of these two classes, Persio D. Lopez, MD, reported at the annual scientific sessions of the American College of Cardiology.

This improvement in the combined endpoint outcome resulted entirely from reduced all-cause mortality. Dual treatment showed no significant association with the incidence of nonfatal MIs or strokes, compared with monotherapy, with rates that were nearly identical regardless of whether patients took one of the agents or both, said Dr. Lopez, a cardiologist at Mount Sinai Morningside and the James J. Peters VA Medical Center, both in New York.
 

Combining classes for hard-to-control diabetes

“We’re not sure what drives combined use” of agents from both drug classes in these types of patients, admitted Dr. Lopez during his talk. “Our hypothesis is that dual treatment is used in patients with harder-to-control diabetes.”

Salim S. Virani, MD, PhD, who practices in the VA system but was not involved with the study, agreed that this is the likely explanation for most instances of high-risk VA patients with diabetes who receive agents from both classes.

Mitchel L. Zoler/MDedge News

“I have a few patients” on both classes, usually “patients with higher starting A1c levels who need greater glycemic control,” said Dr. Virani, professor of medicine at Baylor College of Medicine and a cardiologist at the Michael E. DeBakey VA Medical Center, both in Houston.

U.S. use of either drug class, let alone both, in patients with type 2 diabetes is still struggling to gain traction in U.S. practice and remains limited to a minority of these patients, a prescribing pattern reflected in recent VA data. Analysis of more than half a million patients in the VA system with type 2 diabetes and atherosclerotic cardiovascular disease (ASCVD) who received treatment at any of 130 VA medical centers throughout 2020 showed that 11% had received an SGLT2 inhibitor, and 8% a GLP-1 RA.

The most frequently used antidiabetes drug classes in these patients were insulin in 36%, biguanides in 47%, and sulfonylureas in 22%.

These data also showed a striking level of variability among the 130 VA centers, with some of the sites prescribing either an SGLT2 inhibitor or a GLP-1 RA to as few as about 3% each of these patients, while other centers had a roughly 10-fold higher prescription rate for each of about 25%-30% of their patients with type 2 diabetes and ASCVD.

Despite the overall modest level of use of both classes in these types of patients as recently as 2020, no barriers exist at the VA to prescribing an agent from one or both classes “if you provide a good reason” for a patient to receive the drugs, Dr. Virani said in an interview. He also predicted that use of both classes in these patients, including combination treatment, will likely soon expand.
 

‘A lot of interest’ in combining an SGLT2 inhibitor and a GLP-1 RA

“There will be a lot of interest in combing the two classes. It makes intuitive sense [to treat with both classes] because most patients with diabetes need more than one drug” for glycemic control, he noted. “Why not use two classes that each reduce a patient’s risk” for adverse outcomes involving ASCVD, heart failure, and renal dysfunction, added Dr. Virani.

The study run by Dr. Lopez and his associates used data collected in the National VA Database and included 121,156 patients with both type 2 diabetes and established ASCVD. Using propensity-score matching the researchers compiled three subgroups that each included 5,277 matched patients. One subgroup had patients prescribed an SGLT2 inhibitor, a second subgroup included patients on a GLP-1 RA, and a third subgroup had patients on agents from both classes. Patient matching relied on age, sex, left ventricular ejection fraction, hemoglobin A1c level, systolic blood pressure, and the presence of coronary artery disease or peripheral artery disease.

Patients included in the analysis averaged about 67 years of age; 97% were men, their average body mass index was about 34 kg/m², their average A1c was about 7.9%, their average estimated glomerular filtration rate was about 55-66 mL/min per 1.73 m², and their average left ventricular ejection fraction was about 55%. The database provided a median follow-up of 902 days (about 2.5 years). The prespecified primary endpoint focused on events that occurred during the first year of follow-up, but the investigators also ran a 3-year follow-up analysis on a post hoc basis.

The most common SGLT2 inhibitor received by these patients was empagliflozin (Jardiance), used on virtually everyone who received an agent from this class. In contrast, the GLP-1 RA drugs that patients received split more widely. The most prescribed agent was liraglutide (Victoza), followed by semaglutide (Ozempic), and dulaglutide (Trulicity), with fewer than 5% receiving exenatide (Bydureon, Byetta).

Regarding other treatments, about 97% of all patients received a statin, about 94% were on a renin-angiotensin system inhibitor, about 90% were on metformin, and roughly 75% were on insulin, aspirin, and a beta-blocker, with smaller numbers on other types of agents.

For the study’s primary endpoint, the 1-year incidence of combined ASCVD events including all-cause death, patients on agents from both classes had a significant 46% reduced rate compared with those on an SGLT2 inhibitor only, and a significant 49% reduced rate, compared with those on a GLP-1 RA only. These between-group separations broadened slightly during 3-year follow-up. Dr. Lopez did not report results of a direct comparison between patients on just an SGLT2 inhibitor and those on just a GLP-1 RA.

For the endpoint of all-cause death, those on combined treatment had a 1-year rate that was 83% below the rate among patients on only an SGLT2 inhibitor, and 81% below the rate among patients who received a GLP-1 RA but not the other class.

Dr. Lopez cautioned that selection bias could have influenced the outcomes of patients who received both classes rather than one or the other, and he also highlighted that the analysis relied on administrative data rather than information gleaned from more detailed medical records or prospectively collected findings and was limited by only including a very small number of women.

“Our results need to be validated in prospective studies,” he declared.

Dr. Lopez and Dr. Virani had no commercial disclosures.

WASHINGTON – Patients with type 2 diabetes and established atherosclerotic cardiovascular disease treated with both an sodium-glucose transporter 2 inhibitor and a glucagonlike peptide–1 receptor agonist had a significant 80% cut in their rate of all-cause death during 1-year follow-up, compared with matched patients treated with an agent from either class alone in an observational, retrospective study of more than 15,000 people in the U.S. Veterans Affairs health system.

For the study’s primary endpoint, the combined rate of all-cause death, nonfatal MI, or nonfatal stroke, combined treatment with both an agent from the sodium-glucose transporter 2 (SGLT2) inhibitor class and from the glucagonlike peptide–1 receptor agonist (GLP-1 RA) class linked with a significant, roughly 50% cut in events during 1-year follow-up, compared with patients treated with an agent from just one of these two classes, Persio D. Lopez, MD, reported at the annual scientific sessions of the American College of Cardiology.

This improvement in the combined endpoint outcome resulted entirely from reduced all-cause mortality. Dual treatment showed no significant association with the incidence of nonfatal MIs or strokes, compared with monotherapy, with rates that were nearly identical regardless of whether patients took one of the agents or both, said Dr. Lopez, a cardiologist at Mount Sinai Morningside and the James J. Peters VA Medical Center, both in New York.
 

Combining classes for hard-to-control diabetes

“We’re not sure what drives combined use” of agents from both drug classes in these types of patients, admitted Dr. Lopez during his talk. “Our hypothesis is that dual treatment is used in patients with harder-to-control diabetes.”

Salim S. Virani, MD, PhD, who practices in the VA system but was not involved with the study, agreed that this is the likely explanation for most instances of high-risk VA patients with diabetes who receive agents from both classes.

“I have a few patients” on both classes, usually “patients with higher starting A1c levels who need greater glycemic control,” said Dr. Virani, professor of medicine at Baylor College of Medicine and a cardiologist at the Michael E. DeBakey VA Medical Center, both in Houston.

U.S. use of either drug class, let alone both, in patients with type 2 diabetes is still struggling to gain traction in U.S. practice and remains limited to a minority of these patients, a prescribing pattern reflected in recent VA data. Analysis of more than half a million patients in the VA system with type 2 diabetes and atherosclerotic cardiovascular disease (ASCVD) who received treatment at any of 130 VA medical centers throughout 2020 showed that 11% had received an SGLT2 inhibitor, and 8% a GLP-1 RA.

The most frequently used antidiabetes drug classes in these patients were insulin in 36%, biguanides in 47%, and sulfonylureas in 22%.

These data also showed a striking level of variability among the 130 VA centers, with some of the sites prescribing either an SGLT2 inhibitor or a GLP-1 RA to as few as about 3% each of these patients, while other centers had a roughly 10-fold higher prescription rate for each of about 25%-30% of their patients with type 2 diabetes and ASCVD.

Screening for heart rhythm disorders with a smartphone app and a wearable device had a high rate of correctly detecting atrial fibrillation (AFib) in a large new study.

The mAFA II study, conducted in a mass low-risk population in China, showed that more than 93% of possible AFib episodes detected by the smartphone app were confirmed to be AFib on further monitoring.

Over the course of 4 years of the study, 12,244 (0.4%) of users received a notification of suspected AFib. Among 5,227 people who chose to follow up with a clinician, AFib was confirmed in 93.8% of patients using standard AFib diagnostic tools, including clinical evaluation, an electrocardiogram, and 24-hour Holter monitoring.

In this study, a subset of the individuals screened for AFib were also screened for signs of sleep apnea using the same PPG technology to detect physiological changes in parameters including oxygenation and respiratory rates. The app is also able to determine whether the individual is awake or asleep. Dr. Guo noted that the PPG algorithm for obstructive sleep apnea risk has been validated, compared with polysomnography or home sleep apnea tests.

Using measurements of apnea (signalled by a reduced respiratory rate) and hypopnea (when oxygenation would decrease), the apnea–hypopnea index (AHI) is calculated to determine the severity of the sleep apnea.

Of the 961,931 participants screened for sleep apnea, about 18,000 were notified they may have the condition.  

Obstructive sleep apnea was the most reported common risk factor associated with increased AFib susceptibility, and those individuals with the highest risk sleep apnea (more than 80% monitoring measures with AHI greater than or equal to 30 during sleep) resulted in a 1.5-fold increase in prevalent AFib, Dr. Guo reported.

The mAFA II is the latest of several studies to show that AFib can be detected with various smartphone apps and wearable devices. Previous studies have included the Fitbit Heart Study and the Apple Heart Study.

Dr. Hurwitz told this news organization that the electrophysiologist community is enthusiastic about this new smart device technology.

“I sent my sister one so she could determine if she develops AFib: That’s a pretty good endorsement,” she commented, but added that there are still concerns about the rate of false-positive results.

Dr. Hurwitz said she suspected that there will probably be meaningful differences between the different apps and devices, but the algorithms are all proprietary, and the use of photoplethysmography seems to make a big difference.

She noted that the detection of sleep apnea in the current study was a novel approach. “This is important, as sleep apnea is felt to contribute to AFib, and treating it is felt to decrease the frequency of AFib. Perhaps if patients with sleep apnea were treated before they had documented AFib, the AFib burden could be reduced,” she said.

She added that further studies were needed to fine tune the algorithms and to try and identify other factors or heart rate variabilities that may predict future risk of AFib.

The study was funded by the National Natural Science Foundation of China. Dr. Guo reports no disclosures.

WASHINGTON – Treatment of patients acutely hospitalized for heart failure with the SGLT2 inhibitor empagliflozin led to a rapid incremental increase in patient well-being, compared with control patients who received placebo, that appeared after 2 weeks on treatment in a secondary analysis from 530 randomized patients in the EMPULSE trial.

To Mikhail N. Kosiborod, MD, a coinvestigator for EMPULSE who presented new analysis at the annual scientific sessions of the American College of Cardiology, the message from the quick response of acutely hospitalized patients to empagliflozin was clear: “Use these medications, SGLT2 [sodium-glucose cotransporter 2] inhibitors, as early as possible. We’ve seen with other medications that if they are not prescribed during hospitalization it’s unlikely to happen post discharge,” said Dr. Kosiborod, a cardiologist and codirector of the Haverty Cardiometabolic Center of Excellence at Saint Luke’s Mid America Heart Institute in Kansas City, Mo.

Mitchel L. Zoler/MDedge News

“To our knowledge, the very early improvement in the Kansas City Cardiomyopathy Questionnaire [KCCQ] score – a well-known predictor of cardiovascular death and heart failure readmissions – that we observed with empagliflozin at 15 days is the first such observation, and if corroborated by future studies would suggest that initiation of SGLT2 inhibitors during hospitalization for acute heart failure may be a tool for improving the quality of hospital-to-home transitions,” wrote Dr. Kosiborod and his associates in the published version of their report that appeared concurrently with his report at the meeting.

“These data really support initiation [of empagliflozin or another SGLT2 inhibitor] in hospital, presuming that the patient has no contraindications,” commented Deepak L. Bhatt, MD, professor of medicine at Harvard Medical School in Boston and designated discussant for the report.

“The fact that the benefit kicks in so early is really important, because there is a bit of a penalty to wait” to start treatment with an agent from the SGLT2-inhibitor class, added Dr. Bhatt, who is also executive director of interventional cardiovascular programs at Brigham and Women’s Health, in Boston.

In hospital creates a teachable moment

Starting treatment when a patient is hospitalized is also important as “a teachable moment,” added Dr. Bhatt in an interview. “A physician can say to a patient ‘take this drug, and it will prevent you from returning to the hospital,’ at a time when it’s more likely to be impactful, compared with when a patient is out of the hospital and feeling okay and adherence will likely be much lower.”

Mitchel L. Zoler/MDedge News

The results Dr. Kosiborod reported on quality-of-life parameters measured with the KCCQ expanded on what he and his coinvestigators first reported in 2021 with the primary results from EMPULSE, which enrolled 530 patients at 118 centers in 15 countries during June 2020–February 2021. The trial randomized patients hospitalized for acute heart failure after a brief period of stabilization regardless of their left ventricular ejection fraction or presence of diabetes to receive a single, daily dose of 10 mg of empagliflozin (Jardiance) or placebo starting a median of 3 days after admission. Enrolled patients averaged about 71 years of age, about two-thirds were men, 45% had diabetes, 32% had left ventricular ejection fraction greater than 40%, and about two-thirds had decompensated chronic heart failure, while a third had acute de novo heart failure.

The primary outcome for EMPULSE was a combined endpoint of “total clinical endpoints” that included all-cause mortality, heart failure events (heart failure hospitalizations, urgent heart failure visits, and unplanned outpatient heart failure visits) or at least a 5-point change from baseline in the KCCQ score. Using a “win ratio” method for analyzing the composite endpoint, the primary analysis showed that treatment with empagliflozin for 90 days boosted the win ratio by a significant 36% relative to placebo (Nature Med. 2022 Mar;28[3]: 568-74).
 

Benefit independent of baseline symptomatic impairment

Among the new secondary analyses that Dr. Kosiborod reported was a post-hoc calculation that divided the study cohort into tertiles of baseline KCCQ score. The results showed that the degree of improvement for the primary, 90-day outcome of “total clinical benefit” compared with placebo was consistent across all three KCCQ-score tertiles, showing that empagliflozin’s benefit was “independent of symptomatic impairment at baseline,” he said.

The degree of improvement was also similar across all the tested domains of the KCCQ, including the overall summary, clinical summary, the physical limitations, and quality-of-life scores. Average improvement in KCCQ total symptom score 15 days after treatment onset was 5.35 points, compared with control patients. On an individual-patient basis, a change in KCCQ score of 5 points or more was previously shown to represent a clinically meaningful change.

“Treatment of patients with heart failure is geared to making patients live longer and stay out of the hospital. Enabling patients to feel better is an equally important goal of management, but not all treatments for heart failure can do that. These data from EMPULSE show that, in addition to other clinical benefits, patients also feel better on an SGLT2 inhibitor after just 2 weeks,” Dr. Kosiborod said in an interview.

EMPULSE builds on SOLOIST-WHF

EMPULSE is the second trial to show that an SGLT2 inhibitor can safely and effectively treat patients hospitalized for acute heart failure. Previously, results from the SOLOIST-WHF pivotal trial, which enrolled 1,222 patients with type 2 diabetes recently hospitalized for worsening heart failure, showed that treatment with an investigational, combined SGLT2 and SGLT1 inhibitor, sotagliflozin, resulted in a significant, 33% relative reduction in the primary outcome compared with placebo after a median 9 months of treatment.

“It’s reassuring to see two different drugs and research groups get essentially the same result, showing that starting an SGLT2 inhibitor is safe and effective in selected patients with no contraindications,” said Dr. Bhatt, who was lead investigator for SOLOIST-WHF.

The accumulating evidence for the safety and value of starting an SGLT2 inhibitor when patients are hospitalized for acute heart failure is making this approach increasingly routine for patients who present with heart failure with reduced ejection fraction at Saint Luke’s-Mid America Heart Institute, said Dr. Kosiborod, who is also a professor of medicine at the University of Missouri, Kansas City.

“I think we’ll also gradually start using [an SGLT2 inhibitor] in patients hospitalized with heart failure with preserved ejection fraction [HFpEF],” he added, based on the findings from SOLOIST-WHF and EMPULSE, and also recent evidence showing safety and efficacy of empagliflozin in patients with chronic HFpEF in the EMPEROR-Preserved trial, and for dapagliflozin (Farxiga) in the PRESERVED-HF trial.

Empagliflozin recently received from the U.S. Food and Drug Administration an expanded label indication for treating patients with heart failure with no specification for a level of left ventricular ejection fraction. An outcome trial of dapagliflozin in more than 6,000 patients with HFpEF, DELIVER, is currently ongoing but is expected to report results soon.

“The evidence is already compelling that the benefits outweigh the risk. Results from both SOLOIST-WHF and EMPULSE show that there are no significant safety concerns” when these agents are used in patients with acute heart failure,” Dr. Kosiborod declared.

EMPULSE was sponsored by Boehringer Ingelheim and Eli Lilly, the companies that jointly market empagliflozin (Jardiance). SOLOIST-WHF was sponsored by Sanofi and Lexicon, the companies that have been developing sotagliflozin. Dr. Kosiborod has been a consultant to and received research funding from Boehringer Ingelheim and Eli Lilly, and he has been a consultant or adviser to or led trials on behalf of numerous other companies.

WASHINGTON – Treatment of patients acutely hospitalized for heart failure with the SGLT2 inhibitor empagliflozin led to a rapid incremental increase in patient well-being, compared with control patients who received placebo, that appeared after 2 weeks on treatment in a secondary analysis from 530 randomized patients in the EMPULSE trial.

To Mikhail N. Kosiborod, MD, a coinvestigator for EMPULSE who presented new analysis at the annual scientific sessions of the American College of Cardiology, the message from the quick response of acutely hospitalized patients to empagliflozin was clear: “Use these medications, SGLT2 [sodium-glucose cotransporter 2] inhibitors, as early as possible. We’ve seen with other medications that if they are not prescribed during hospitalization it’s unlikely to happen post discharge,” said Dr. Kosiborod, a cardiologist and codirector of the Haverty Cardiometabolic Center of Excellence at Saint Luke’s Mid America Heart Institute in Kansas City, Mo.

“To our knowledge, the very early improvement in the Kansas City Cardiomyopathy Questionnaire [KCCQ] score – a well-known predictor of cardiovascular death and heart failure readmissions – that we observed with empagliflozin at 15 days is the first such observation, and if corroborated by future studies would suggest that initiation of SGLT2 inhibitors during hospitalization for acute heart failure may be a tool for improving the quality of hospital-to-home transitions,” wrote Dr. Kosiborod and his associates in the published version of their report that appeared concurrently with his report at the meeting.

“These data really support initiation [of empagliflozin or another SGLT2 inhibitor] in hospital, presuming that the patient has no contraindications,” commented Deepak L. Bhatt, MD, professor of medicine at Harvard Medical School in Boston and designated discussant for the report.

“The fact that the benefit kicks in so early is really important, because there is a bit of a penalty to wait” to start treatment with an agent from the SGLT2-inhibitor class, added Dr. Bhatt, who is also executive director of interventional cardiovascular programs at Brigham and Women’s Health, in Boston.

In hospital creates a teachable moment

Starting treatment when a patient is hospitalized is also important as “a teachable moment,” added Dr. Bhatt in an interview. “A physician can say to a patient ‘take this drug, and it will prevent you from returning to the hospital,’ at a time when it’s more likely to be impactful, compared with when a patient is out of the hospital and feeling okay and adherence will likely be much lower.”

Mitchel L. Zoler/MDedge News

The results Dr. Kosiborod reported on quality-of-life parameters measured with the KCCQ expanded on what he and his coinvestigators first reported in 2021 with the primary results from EMPULSE, which enrolled 530 patients at 118 centers in 15 countries during June 2020–February 2021. The trial randomized patients hospitalized for acute heart failure after a brief period of stabilization regardless of their left ventricular ejection fraction or presence of diabetes to receive a single, daily dose of 10 mg of empagliflozin (Jardiance) or placebo starting a median of 3 days after admission. Enrolled patients averaged about 71 years of age, about two-thirds were men, 45% had diabetes, 32% had left ventricular ejection fraction greater than 40%, and about two-thirds had decompensated chronic heart failure, while a third had acute de novo heart failure.

The primary outcome for EMPULSE was a combined endpoint of “total clinical endpoints” that included all-cause mortality, heart failure events (heart failure hospitalizations, urgent heart failure visits, and unplanned outpatient heart failure visits) or at least a 5-point change from baseline in the KCCQ score. Using a “win ratio” method for analyzing the composite endpoint, the primary analysis showed that treatment with empagliflozin for 90 days boosted the win ratio by a significant 36% relative to placebo (Nature Med. 2022 Mar;28[3]: 568-74).
 

Benefit independent of baseline symptomatic impairment

Among the new secondary analyses that Dr. Kosiborod reported was a post-hoc calculation that divided the study cohort into tertiles of baseline KCCQ score. The results showed that the degree of improvement for the primary, 90-day outcome of “total clinical benefit” compared with placebo was consistent across all three KCCQ-score tertiles, showing that empagliflozin’s benefit was “independent of symptomatic impairment at baseline,” he said.

The degree of improvement was also similar across all the tested domains of the KCCQ, including the overall summary, clinical summary, the physical limitations, and quality-of-life scores. Average improvement in KCCQ total symptom score 15 days after treatment onset was 5.35 points, compared with control patients. On an individual-patient basis, a change in KCCQ score of 5 points or more was previously shown to represent a clinically meaningful change.

“Treatment of patients with heart failure is geared to making patients live longer and stay out of the hospital. Enabling patients to feel better is an equally important goal of management, but not all treatments for heart failure can do that. These data from EMPULSE show that, in addition to other clinical benefits, patients also feel better on an SGLT2 inhibitor after just 2 weeks,” Dr. Kosiborod said in an interview.

Structural aortic valve deterioration (SVD) at 5 years is lower following repair with a contemporary transcatheter implantation (TAVI) device than with surgery, according to a pooled analysis of major trials.

For healthier patients with a relatively long life expectancy, this is important information for deciding whether to undergo TAVI or surgical aortic valve repair (SAVR), Michael J. Reardon, MD, said at the annual scientific sessions of the American College of Cardiology.

“Every week I get this question about which repair is more durable,” said Dr. Reardon, whose study was not only designed to compare device deterioration but to evaluate the effect of SVD on major outcomes.

In this analysis, the rates of SVD were compared for the self-expanding supra-annular CoreValve Evolut device and SAVR. The SVD curves separated within the first year. At 5 years, the differences were highly significant favoring TAVI (2.57% vs. 4.38%; P = .0095).

As part of this analysis, the impact of SVD was also assessed independent of type of repair. At 5 years, those with SVD relative to those without had an approximately twofold increase in all-cause mortality, cardiovascular mortality, and hospitalization of aortic valve worsening. These risks were elevated regardless of type of valve repair.

The data presented by Dr. Reardon can be considered device specific. The earlier PARTNER 2A study comparing older- and newer-generation TAVI devices with SAVR produced a different result. When a second-generation balloon-expandable SAPIEN XT device and a third-generation SAPIEN 3 device were compared with surgery, neither device achieved lower SVD rates relative to SAVR.

In PARTNER 2A, the SVD rate for the older device was nearly three times greater than SAVR (1.61 vs. 0.58 per 100 patient-years). The numerically higher SVD rates for the newer device (0.68 vs. 0.58 per 100 patient-years) was not statistically different, but the TAVI device was not superior.

More than 4,000 patients evaluated at 5 years

In the analysis presented by Dr. Reardon, data were pooled from the randomized CoreValve U.S. High-Risk Pivotal Trial and the SURTAVI Intermediate Risk Trial. Together, these studies randomized 971 patients to surgery and 1,128 patients to TAVI. Data on an additional 2,663 patients treated with the Evolut valve in two registries were added to the randomized trial data, providing data on 4,762 total patients with 5-year follow-up.

SVD was defined by two criteria. The first was a mean gradient increase of at least 10 mm Hg plus a mean overall gradient of at least 20 mm Hg as measured with echocardiography and assessed, when possible, by an independent core laboratory. The second was new-onset or increased intraprosthetic aortic regurgitation of at least moderate severity.

When graphed over time, the SVD curves separated in favor of TAVI after about 6 months of follow-up. The shape of the curves also differed. Unlike the steady rise in SVD observed in the surgery group, the SVD rate in the TAVI group remained below 1% for almost 4 years before beginning to climb.

There was greater relative benefit for the TAVI device in patients with annular diameters of 23 mm or less. Unlike the rise in SVD rates that began about 6 months after SAVR, the SVD rates in the TAVI patients remained at 0% for more than 2 years. At 5 years, the differences remained significant favoring TAVI (1.39% vs. 5.86%; P = .049).

In those with larger annular diameters, there was still a consistently lower SVD rate over time for TAVI relative to SAVR, but the trend for an advantage at 5 years fell just short of significance (2.48% vs. 3.96%; P = .067).
 

SVD linked to doubling of mortality

SVD worsened outcomes. When all data surgery and TAVI data were pooled, the hazard ratios corresponded with about a doubling of risk for major adverse outcomes, including all-cause mortality (HR, 1.98; P < .001), cardiovascular mortality (HR, 1.82; P = .008), and hospitalization for aortic valve disease or worsening heart failure (HR, 2.11; P = .01). The relative risks were similar in the two treatment groups, including the risk of all-cause mortality (HR, 2.24; P < .001 for TAVI vs. HR, 2.45; P = .002 for SAVR).

The predictors for SVD on multivariate analysis included female sex, increased body surface area, prior percutaneous coronary intervention, and a prior diagnosis of atrial fibrillation.

Design improvements in TAVI devices are likely to explain these results, said Dr. Reardon, chair of cardiovascular research at Houston Methodist Hospital.

“The CoreValve/Evolut supra-annular, self-expanding bioprosthesis is the first and only transcatheter bioprosthesis to demonstrate lower rates of SVD, compared with surgery,” Dr. Reardon said.

This analysis validated the risks posed by the definition of SVD applied in this study, which appears to be a practical tool for tracking valve function and patient risk. Dr. Reardon also said that the study confirms the value of serial Doppler transthoracic echocardiography as a tool for monitoring SVD.

Several experts agreed that this is important new information.

“This is a remarkable series of findings,” said James McClurken, MD, who is a cardiovascular surgeon affiliated with Temple University, Philadelphia, and practices in Doylestown, Penn. By both demonstrating the prognostic importance of SVD and showing differences between the study device and SAVR, this trial will yield practical data to inform patients about relative risks and benefits.

Athena Poppas, MD, the new president of the ACC and a professor of medicine at Brown University, Providence, R.I., called this study “practice changing” for the same reasons. She also thinks it has valuable data for guiding choice of intervention.

Overall, the data are likely to change thinking about the role of TAVI and surgery in younger, fit patients, according to Megan Coylewright, MD, chief of cardiology at Erlanger Cardiology, Chattanooga, Tenn.

“There are patients [in need of aortic valve repair] with a long life expectancy who have been told you have to have a surgical repair because we know they last longer,” she said. Although she said that relative outcomes after longer follow-up remain unknown, “I think this does throw that comment into question.”

Dr. Reardon has financial relationships with Abbott, Boston Scientific, Medtronic, and Gore Medical. Dr. Poppas and McClurken reported no potential financial conflicts of interest. Dr. Coylewright reported financial relationships with Abbott, Alleviant, Boston Scientific, Cardiosmart, Edwards Lifesciences, Medtronic, and Occlutech. The study received financial support from Medtronic.

Data on an additional 2,663 patients treated with the Evolut valve in two registries were added to the randomized trial data, providing data on 4,762 total patients with 5-year follow-up.

SVD was defined by two criteria. The first was a mean gradient increase of at least 10 mm Hg plus a mean overall gradient of at least 20 mm Hg as measured with echocardiography and assessed, when possible, by an independent core laboratory. The second was new-onset or increased intraprosthetic aortic regurgitation of at least moderate severity.

When graphed over time, the SVD curves separated in favor of TAVI after about 6 months of follow-up. The shape of the curves also differed. Unlike the steady rise in SVD observed in the surgery group, the SVD rate in the TAVI group remained below 1% for almost 4 years before beginning to climb.

There was greater relative benefit for the TAVI device in patients with annular diameters of 23 mm or less. Unlike the rise in SVD rates that began about 6 months after SAVR, the SVD rates in the TAVI patients remained at 0% for more than 2 years. At 5 years, the differences remained significant favoring TAVI (1.39% vs. 5.86%; P = .049).

In those with larger annular diameters, there was still a consistently lower SVD rate over time for TAVI relative to SAVR, but the trend for an advantage at 5 years fell just short of significance (2.48% vs. 3.96%; P = .067).
 

SVD linked to doubling of mortality

SVD worsened outcomes. When all data surgery and TAVI data were pooled, the hazard ratios corresponded with about a doubling of risk for major adverse outcomes, including all-cause mortality (HR, 1.98; P < .001), cardiovascular mortality (HR, 1.82; P = .008), and hospitalization for aortic valve disease or worsening heart failure (HR, 2.11; P = .01). The relative risks were similar in the two treatment groups, including the risk of all-cause mortality (HR, 2.24; P < .001 for TAVI vs. HR, 2.45; P = .002 for SAVR).

The predictors for SVD on multivariate analysis included female sex, increased body surface area, prior percutaneous coronary intervention, and a prior diagnosis of atrial fibrillation.

Design improvements in TAVI devices are likely to explain these results, said Dr. Reardon, chair of cardiovascular research at Houston Methodist Hospital.

“The CoreValve/Evolut supra-annular, self-expanding bioprosthesis is the first and only transcatheter bioprosthesis to demonstrate lower rates of SVD, compared with surgery,” Dr. Reardon said.

This analysis validated the risks posed by the definition of SVD applied in this study, which appears to be a practical tool for tracking valve function and patient risk. Dr. Reardon also said that the study confirms the value of serial Doppler transthoracic echocardiography as a tool for monitoring SVD.

Several experts agreed that this is important new information.

“This is a remarkable series of findings,” said James McClurken, MD, who is a cardiovascular surgeon affiliated with Temple University, Philadelphia, and practices in Doylestown, Penn. By both demonstrating the prognostic importance of SVD and showing differences between the study device and SAVR, this trial will yield practical data to inform patients about relative risks and benefits.

Athena Poppas, MD, the new president of the ACC and a professor of medicine at Brown University, Providence, R.I., called this study “practice changing” for the same reasons. She also thinks it has valuable data for guiding choice of intervention.

Overall, the data are likely to change thinking about the role of TAVI and surgery in younger, fit patients, according to Megan Coylewright, MD, chief of cardiology at Erlanger Cardiology, Chattanooga, Tenn.

“There are patients [in need of aortic valve repair] with a long life expectancy who have been told you have to have a surgical repair because we know they last longer,” she said. Although she said that relative outcomes after longer follow-up remain unknown, “I think this does throw that comment into question.”

Dr. Reardon has financial relationships with Abbott, Boston Scientific, Medtronic, and Gore Medical. Dr. Poppas and McClurken reported no potential financial conflicts of interest. Dr. Coylewright reported financial relationships with Abbott, Alleviant, Boston Scientific, Cardiosmart, Edwards Lifesciences, Medtronic, and Occlutech. The study received financial support from Medtronic.
