For patients with postural tachycardia syndrome (POTS), dietary sodium intake can be increased more confidently, suggests the first study to yield solid evidence to support this treatment strategy.

The results showed that high dietary sodium intake can lower plasma norepinephrine levels and ameliorate standing and orthostatic tachycardia for patients with POTS.

“These results suggest that increasing dietary salt is a good rationale for treatment of this condition, and this study gives reassurance we are doing the right thing for POTS patients by increasing their sodium intake,” senior author Satish R. Raj, MD, said in an interview.

The study, with lead author Emily M. Garland, PhD, was published online April 26, 2021, in the Journal of the American College of Cardiology.

Dr. Raj, who is professor of cardiac science at the University of Calgary (Alta.), explained that POTS includes a spectrum of disorders that affect the automatic nervous system, which regulates heart rate and blood pressure.

“It is a disorder of orthostatic intolerance – patients feel better when they lie down. It differs from orthostatic hypotension in that, when a POTS patient stands up, the blood pressure does not necessarily drop, but the heart rate increases excessively.”

Although it is normal for the heart rate to increase somewhat on standing, among patients with POTS, the heart rate increases excessively. The condition is defined as an orthostatic heart rate increase of at least 30 beats/min (or 40 beats/min among individuals aged 12-19 years ) in the absence of orthostatic hypotension.

The disorder is characterized by a range of symptoms, including lightheadedness, shortness of breath, palpitations, and exertional intolerance, that are worse when in an upright position. Patients also experience chronic fatigue and perceived cognitive impairment, Dr. Raj noted.

The typical demographic for POTS is young women; the condition often starts during the teenage years.

Patients often have low blood volume, so one approach to treatment is to increase the intake of salt and water so as to increase blood volume.

“This is one of the mainstays of treatment, but it has never really been properly studied,” Dr. Raj commented. Increasing salt intake “is an unusual message from a cardiologist, and there have been concerns that we are making recommendations against traditional advice, so we urgently need evidence to support this recommendation.”

The current crossover study enrolled 14 patients with POTS and 13 healthy control persons who, over a period of 6 days, underwent treatment with a low-sodium diet (10 mEq sodium per day) or a high-sodium diet (300 mEq sodium per day).

Supine and standing heart rate, blood pressure, serum aldosterone level, plasma renin activity, blood volume, and plasma norepinephrine and epinephrine levels were measured.

Results showed that, among the POTS patients, the high-sodium diet reduced upright heart rate and the change in heart rate on standing, compared with the low-sodium diet.

Heart rate increased by 46 beats/min with the high-sodium diet versus 60 beats/min with the low-sodium diet.

Total blood volume and plasma volume increased, and standing norepinephrine levels decreased with the high-sodium diet, compared with the low-sodium diet.

However, upright heart rate, change in heart rate, and upright norepinephrine levels remained higher among POTS patients than among control persons receiving the high-sodium diet.

There was a nonsignificant trend for a lower symptom burden score among the POTS patients who received the high-sodium diet in comparison with those taking the low-sodium diet. Scores for mental confusion, palpitations, lightheadedness, and headache trending downward on the high-sodium diet.

“We found that high levels of dietary salt did what we hoped, with increased blood volume and reduced norepinephrine levels on standing and reduced excessive increase in heart rate. While it didn’t completely normalize heart rate, this was reduced significantly,” Dr. Raj said.

Another observation from the study was that the increased salt intake seemed to be beneficial across the whole spectrum of patients.

“There are some patients who have very high levels of sympathetic activation, and there have been anecdotal reports that increasing salt may not work so well in this group,” he said. “In this study, we didn’t differentiate, but average norepinephrine levels were very high, and many patients would be considered to be hyperadrenergic. Our results suggest this treatment will help these patients too.”

He noted that sodium intake was increased in this study just through diet. “We had a special metabolic kitchen. In clinical practice, we advise patients to add regular table salt to their food, and we only use salt tablets when they cannot tolerate so much salt in their diet.”

Recognizing that there may be concerns about hypertension with long-term use of such a treatment, Dr. Raj said there were no signs of an increase in blood pressure in this study. “But this should be considered a short-term therapy for the time being, and patients need to be reassessed every few years as their physiology changes.”

The authors estimated that POTS affects up to 1% of the population. Because there is no diagnostic code for the condition at present, all incidence data are estimates.

Dr. Raj pointed out that potentially a lot of people are affected, but there is little recognition of the condition among patients and physicians.

“Many family doctors are unaware of POTS,” he noted. “Patients often have to research their symptoms themselves and inform their doctor of the condition. Many patients wait years and often see many different doctors before getting a correct diagnosis.”

He explained that patients with POTS are often diagnosed as having a psychiatric illness. “They are mainly young women with palpitations, heart pounding, shakiness, which is often labeled as anxiety.”

Dr. Raj urged clinicians to consider POTS if patients have symptoms that are worse when standing up. The diagnosis is confirmed if their blood pressure doesn’t fall when standing up but their heart rate increases by at least 30 beats/min.

He noted that not enough specialists treat this condition, so family doctors need to be able to diagnose and initiate treatment. If more aggressive treatment is required, patients can be referred to a specialist.

“One of the problems is that this condition pans across different medical specialties. No one field owns it, so it tends to get ignored. But there are clinicians who are interested in POTS, and the key is finding one of these,” he said.

“We have finally established that this high-sodium diet works as treatment for POTS,” he concluded. “We have been using it for some time, but now we have evidence for its use across the whole spectrum of patients.”

In an accompanying editorial (J Am Coll Cardiol. 2021 May 4;77[17]:2185-2186), Blair P. Grubb, MD, University of Toledo (Ohio) Medical Center, wrote that this “superb study by Garland et al. helps better establish our understanding of the pathophysiologic process taking place in POTS while at the same time providing good evidence for the augmentation of dietary sodium as one of the cornerstones of treatment.”

He added that the field needs more such studies “in our quest to better understand POTS and to elaborate therapeutic modalities to help those suffering from this debilitating illness.”

The study was supported in part by the National Heart, Lung, and Blood Institute; the National Center for Advancing Translational Sciences; and the Vanderbilt Hormone and Analytical Services Core. Dr. Raj has served as a consultant for Lundbeck NA and Theravance; has served as chair of the data safety and monitoring board for Arena Pharmaceuticals and as Cardiac Arrhythmia Network of Canada network investigator; and has served on the medical advisory board of Dysautonomia International and PoTS UK, both without financial compensation.

AHA issues new advice on managing stage 1 hypertension

Article Type

Wed, 05/05/2021 - 10:37

 

Clinicians should consider the use of medication for adults with untreated stage 1 hypertension (130-139/80-89 mm Hg) whose 10-year risk for atherosclerotic cardiovascular disease is <10% and who fail to meet the blood pressure goal of <130/80 mm Hg after 6 months of guideline-based lifestyle therapy, the American Heart Association (AHA) advises in new scientific statement.

The statement was published online April 29 in Hypertension.

The recommendation complements the 2017 American College of Cardiology/American Heart Association Blood Pressure Management Guidelines, which do not fully address how to manage untreated stage 1 hypertension, the AHA says.

“There are no treatment recommendations in current guidelines for patients who are at relatively low short-term risk of heart disease when blood pressure does not drop below 130 mm Hg after six months of recommended lifestyle changes. This statement fills that gap,” Daniel W. Jones, MD, chair of the statement writing group and a past president of the AHA, said in a news release.

If after 6 months with lifestyle changes, blood pressure does not improve, lifestyle therapy should be continued and “clinicians should consider adding medications to control blood pressure,” said Dr. Jones, professor and dean emeritus, University of Mississippi, Jackson.

Healthy lifestyle changes to lower blood pressure include achieving ideal body weight, exercising (30 min of moderate to vigorous physical activity on most days, if possible), limiting dietary sodium, enhancing potassium intake, and following the Dietary Approaches to Stop Hypertension (DASH) diet, which is plentiful in fruits and vegetables with low-fat dairy products and reduced saturated fat and total fat. In addition, patients should be advised to limit alcohol intake and to not smoke.

The writing group acknowledges that these goals can be hard to achieve and maintain over time.

“It is very hard in America and most industrialized countries to limit sodium sufficiently to lower blood pressure, and it is difficult for all of us to maintain a healthy weight in what I refer to as a toxic food environment,” Dr. Jones said.

“We want clinicians to advise patients to take healthy lifestyle changes seriously and do their best. We certainly prefer to achieve blood pressure goals without adding medication; however, successfully treating high blood pressure does extend both years and quality of life,” said Dr. Jones.

The AHA statement also addresses cases in which adults were found to have hypertension during adolescence or childhood and were prescribed antihypertensive drug therapy.

In this patient population, clinicians should consider the original indications for starting antihypertensive drug treatment and the need to continue the medication and lifestyle therapy as young adults, the AHA advises.

“In young adults with stage 1 hypertension who are not controlled with lifestyle therapy, special consideration should be given to use of antihypertensive medication in individuals with a family history of premature CVD, a history of hypertension during pregnancy, or a personal history of premature birth,” the AHA states.

The scientific statement was prepared by the volunteer writing group on behalf of the AHA Council on Hypertension; the Council on the Kidney in Cardiovascular Disease; the Council on Arteriosclerosis, Thrombosis and Vascular Biology; the Council on Cardiovascular Radiology and Intervention; the Council on Lifelong Congenital Heart Disease and Heart Health in the Young; and the Stroke Council.

The authors have disclosed no relevant financial relationships.

USPSTF reaffirms advice to screen all adults for hypertension

Article Type

Mon, 05/03/2021 - 08:54

The U.S. Preventive Services Task Force continues to recommend that clinicians screen all adults aged 18 years and older for high blood pressure and that they confirm a diagnosis of hypertension with blood pressure measurements taken outside the office before starting treatment.

This grade A recommendation is consistent with the 2015 recommendation from the task force.

Hypertension affects approximately 45% of adults in the United States and is a major contributing risk factor for heart failure, myocardial infarction, stroke, and chronic kidney disease.

Using a reaffirmation deliberation process, the USPSTF concluded with high certainty that there was “substantial net benefit” from screening adults for hypertension in clinical office settings.

The reaffirmation recommendation clarifies that initial screening should be performed with office-based blood pressure measurement.

The task force found “convincing” evidence that screening for and treatment of hypertension detected in clinical office settings substantially reduces cardiovascular events and have few major harms.

To confirm a diagnosis of hypertension outside the office before starting treatment, ambulatory blood pressure monitoring or home blood pressure monitoring is recommended. Blood pressure measurements should be taken at the brachial artery with a validated and accurate device in a seated position after 5 minutes of rest.

Although evidence regarding optimal screening intervals is limited, the task force says “reasonable” options include screening for hypertension every year for adults aged 40 years or older and for adults who are at increased risk for hypertension, such as Black persons, persons with high-normal blood pressure, or those who are overweight or obese.

Screening less frequently (every 3-5 years) is appropriate for adults aged 18-39 years who are not at increased risk for hypertension and who have received a prior blood pressure reading that was in the normal range, said the task force, led by Alex Krist, MD, MPH, Virginia Commonwealth University, Richmond.

The recommendation and supporting evidence report were published online April 27, 2021, in JAMA.
 

‘Screening is just the first step’

In a JAMA editorial, Marwah Abdalla, MD, MPH, Columbia University Irving Medical Center, New York, and coauthors said the COVID-19 pandemic has demonstrated that “rapid and significant innovation in science, health care, and society is possible. Implementing the latest USPSTF recommendations will require widespread changes to how the health care system and other entities screen for hypertension.

“Yet screening is just the first step in a long road to controlling hypertension. Medicine and society need to implement a variety of interventions proven to be effective in controlling blood pressure at scale,” the editorialists said.

“Additionally, these efforts need to consider how to achieve success for all people. This will require working to address the roots of structural racism and reduce the racial disparities that increase hypertension-related morbidity and mortality for vulnerable populations,” they added.

“These changes will take innovation in how care delivery is provided at both the individual and population levels – lessons the health care system and society learned are achievable through the response to the COVID-19 pandemic,” Dr. Abdalla and colleagues concluded.

The USPSTF and Dr. Abdalla reported no relevant financial relationships. One editorialist reported receiving personal fees from Livongo and Cerner and grants from Bristol-Myers Squibb.

The U.S. Preventive Services Task Force continues to recommend that clinicians screen all adults aged 18 years and older for high blood pressure and that they confirm a diagnosis of hypertension with blood pressure measurements taken outside the office before starting treatment.

This grade A recommendation is consistent with the 2015 recommendation from the task force.

Hypertension affects approximately 45% of adults in the United States and is a major contributing risk factor for heart failure, myocardial infarction, stroke, and chronic kidney disease.

Using a reaffirmation deliberation process, the USPSTF concluded with high certainty that there was “substantial net benefit” from screening adults for hypertension in clinical office settings.

The reaffirmation recommendation clarifies that initial screening should be performed with office-based blood pressure measurement.

The task force found “convincing” evidence that screening for and treatment of hypertension detected in clinical office settings substantially reduces cardiovascular events and have few major harms.

To confirm a diagnosis of hypertension outside the office before starting treatment, ambulatory blood pressure monitoring or home blood pressure monitoring is recommended. Blood pressure measurements should be taken at the brachial artery with a validated and accurate device in a seated position after 5 minutes of rest.

Although evidence regarding optimal screening intervals is limited, the task force says “reasonable” options include screening for hypertension every year for adults aged 40 years or older and for adults who are at increased risk for hypertension, such as Black persons, persons with high-normal blood pressure, or those who are overweight or obese.

Screening less frequently (every 3-5 years) is appropriate for adults aged 18-39 years who are not at increased risk for hypertension and who have received a prior blood pressure reading that was in the normal range, said the task force, led by Alex Krist, MD, MPH, Virginia Commonwealth University, Richmond.

The recommendation and supporting evidence report were published online April 27, 2021, in JAMA.

Transgender hormone therapy linked to blood pressure changes

Article Type

Thu, 04/22/2021 - 14:10

 

Transgender people treated with gender-affirming hormone therapy show distinctive changes in blood pressure that begin soon after treatment initiation and do not subside over years of treatment, according to the largest and longest observational study to date to look at the issue.

“Many physicians may not be aware of the changes to blood pressure in trans patients who start hormone therapy,” senior author Michael S. Irwig, MD, director of transgender medicine at Beth Israel Deaconess Medical Center in Boston, told this news organization.

“The take-away message for physicians is to monitor blood pressure both before and after starting hormone therapy in transgender patients, as over a third of transgender individuals had stage 1 hypertension before starting hormone therapy, and many had their blood pressure increase after starting hormone therapy.”

Mean blood pressure increases in transgender males, decreases in females

In the study, published in Hypertension, Katherine Banks, MD, George Washington University, Washington, and colleagues, followed 470 transgender adult patients for up to 5 years.

The mean systolic blood pressure levels in transgender female patients (male at birth) significantly decreased compared with baseline within a few months of them starting gender-affirming hormone treatment.

Conversely, the systolic blood pressure levels in transgender males (females at birth) who were treated with testosterone increased over the same period.

There were no significant changes in the groups in terms of diastolic blood pressure, consistent with other studies.

“Our study is the first to describe the time course of the blood pressure effects of gender-affirming hormone therapy and to compare the rates of elevated blood pressure and stage 1 and stage 2 hypertension using blood pressure readings from gender-diverse individuals pre- and post–gender-affirming hormone therapy,” the authors note.

Gender-affirming hormone therapy – which has been prescribed to transgender patients for more than 25 years – typically involves a combination of estrogen and an anti-androgen for males transitioning to female, while the therapy for those transitioning to male generally only involves testosterone.

The therapy has previously been linked to various cardiac effects, with evidence showing transgender men have as much as a 5-times greater risk of heart attack versus cisgender women, the authors note.

Although the American Heart Association issued a 2020 Scientific Statement addressing the cardiovascular disease risk, evidence on the effects specifically on blood pressure in transgender patients has been inconsistent.

For the new study, Dr. Banks and colleagues enrolled 247 transgender females and 223 transgender males who were treated between 2007 and 2015 at two medical centers in Washington, D.C. Of the individuals, who had a mean age of 27.8, about 27% were non-White and 16% were Latinx.

They had blood pressure measurements taken at baseline and at follow-up clinical visits for up to 57 months following the initiation of gender-affirming hormone therapy.

Over the follow-up period, the transgender females had decreases in mean systolic blood pressure of 4.0 mm Hg within 2 to 4 months of starting hormone therapy (P < .0001) and mean declines of 6.0 mm Hg were further observed at 11 to 21 months compared with baseline.

In transgender males, the mean systolic blood pressure increased by 2.6 mm Hg at 2 to 4 months (P = .02), and by 2.9 mm Hg at 11 to 21 months after starting therapy.

Furthermore, “although the average increase in systolic blood pressure was 2.6 mm Hg in transgender men within 2 to 4 months, some patients had much higher increases,” Dr. Irwig noted.

As many as 40% of transgender men had stage 1 hypertension after 11 to 21 months of hormone therapy.

The blood pressure changes in transgender males and females were observed across all three racial ethnic groups of Whites, Blacks, and Latinx, and the changes remained consistent throughout the entire follow-up period of approximately 5 years while hormone therapy was continued.

In addition to the changes after therapy initiation, the researchers note that more than one-third of individuals in both groups had stage 1 hypertension even before starting hormone therapy.

The findings are a concern in light of “clear evidence linking hypertension and higher blood pressure with cardiovascular events such as stroke and heart attacks,” Dr. Irwig said.

 

 

Protective effects for transgender females?

Transgender females showed as much as a 47% decrease in the prevalence of stage 2 hypertension, from 19% to 10%, within 2 to 4 months of treatment with gender-affirming hormone therapy (P = .001), and the rate declined further to 8% at 11 to 21 months, suggesting a protective effect of the treatment.

“The rate of stage 2 hypertension did drop in transgender feminine individuals, which could be protective and lower their risk for cardiovascular events,” Dr. Irwig said.

“This was not a surprise, as lowering testosterone and the use of spironolactone can lower blood pressure,” he noted.

Exceptions in both groups

Of note, a sizable proportion of patients had blood pressure changes that were in fact the opposite of the patterns seen in the majority of their gender group.

Specifically, while 42% to 53% of the transgender females had systolic blood pressure readings of at least 5 mm Hg lower than their baseline readings, up to 32% had increases of at least 5 mm Hg compared to baseline readings.

Likewise, whereas 41% to 59% of transgender males had increases of at least 5 mm Hg compared with baseline, up to 35% had levels that were at least 5 mm Hg lower than baseline.

“It was a surprise that over a quarter of individuals had changes opposite to the mean changes,” Dr. Irwig said.

The differing blood pressure changes underscore that “more research is needed to determine which formulations of estrogen, testosterone, and antiandrogens are optimal regarding blood pressure and cardiovascular health, especially in older individuals,” the authors note.

Gender-affirming hormone therapy formulations differ

Various formulations for gender-affirming hormone regimens are available, including oral, transdermal, sublingual, and intramuscular preparations.

In the study, 77% to 91% of transgender males were on intramuscular testosterone injections, with the rest on transdermal formulations, and 92% of transgender female patients were started on oral estradiol, with mean doses generally increasing over time.  

The study’s results are consistent with evidence from other studies, with 7 of 8 involving transgender males showing mean increases in systolic blood pressure ranging from 1 to 14 mm Hg.

Previous research supports cardiovascular risk

As reported by this news organization, other emerging research on cardiovascular risks to transgender people include a recent study showing more than 10% of transgender males were found to have hematocrit levels that could put them at risk for blood clots.

And further research on transgender youth also shows concerning elevations in lipids and other cardiovascular risks.

The authors have disclosed no relevant financial relationships.

Remote cardio visits expand access for underserved during COVID

Article Type
Changed
Thu, 08/26/2021 - 15:48

Remote cardiology clinic visits during COVID-19 were used more often by certain traditionally underserved patient groups, but were also associated with less frequent testing and prescribing, new research shows.

Dr. Neal Yuan

“The COVID-19 pandemic has led to an unprecedented shift in ambulatory cardiovascular care from in-person to remote visits,” lead author Neal Yuan, MD, a cardiology fellow at the Smidt Heart Institute, Cedars-Sinai Medical Center, Los Angeles, said in an interview.

Their findings were published online April 5 in JAMA Network Open.

“We wanted to explore whether the transition to remote visits was associated with disparities in how patients accessed care, and also how this transition affected diagnostic test ordering and medication prescribing,” Dr. Yuan said.

The researchers used electronic health records data for all ambulatory cardiology visits at an urban, multisite health system in Los Angeles County during two periods: April 1 to Dec. 31, 2019, the pre-COVID era; and April 1 to Dec. 31, 2020, the COVID era.

The investigators compared patient characteristics and frequencies of medication ordering and cardiology-specific testing across four visit types: pre-COVID in person, used as reference; COVID-era in person; COVID-era video; and COVID-era telephone.

The study looked at 176,781 ambulatory cardiology visits. Of these visits, 87,182 were conducted in person in the pre-COVID period; 74,498 were conducted in person in the COVID era; 4,720 were COVID-era video visits; and 10,381 were COVID-era telephone visits.

In the study cohort, 79,572 patients (45.0%) were female, 127,080 patients (71.9%) were non-Hispanic White, and the mean age was 68.1 years (standard deviation, 17.0).

Patients accessing COVID-era remote visits were more likely to be Asian, Black, or Hispanic, to have private insurance, and to have cardiovascular comorbidities, such as hypertension and heart failure.

Also, patients whose visits were conducted by video were significantly younger than patients whose visits were conducted in person or by telephone (P < .001).

In addition, the study found that clinicians ordered fewer diagnostic tests, such as electrocardiograms and echocardiograms, and were less likely to order any medication, in the pre-COVID era than during the COVID era.

“If you don’t have a patient in front of you, it’s much more difficult to get a physical exam or obtain reliable vital signs,” said Dr. Yuan. Communication can sometimes be difficult, often because of technical issues, like a bad connection. “You might be more reticent to get testing or to prescribe medications if you don’t feel confident knowing what the patient’s vital signs are.”

In addition, he added, “a lot of medications used in the cardiology setting require monitoring patients’ kidney function and electrolytes, and if you can’t do that reliably, you might be more cautious about prescribing those types of medications.”
 

An eye-opening study

Cardiologist Nieca Goldberg, MD, medical director of the New York University Langone womens’ heart program and spokesperson for the American Heart Association, recounted her experience with telemedicine at the height of the pandemic in New York, when everything, including medical outpatient offices, had to close.

Dr. Nieca Goldberg

“We were experienced with telemedicine because we had started a virtual urgent care program well ahead of the pandemic,” she said. “We started using that to screen people with potential COVID symptoms so that they wouldn’t have to come into the hospital, the medical center, or to the offices and expose people. We learned that it was great to have the telemedicine option from the infectious disease standpoint, and I did visits like that for my own patient population.”

An equally if not more important finding from the study is the fact that telemedicine increased access to care among traditionally underserved demographics, she said.

“This is eye-opening, that you can actually improve access to care by doing telemedicine visits. It was really important to see that telemedicine has added benefit to the way we can see people in the health care system.”

Telemedicine visits had a positive impact at a time when people were isolated at home, Dr. Goldberg said.

“It was a way for them to connect with their doctor and in some ways it was more personal,” she added. “I actually got to meet some of my patients’ family members. It was like making a remote house call.”

Stable cardiology patients can take their blood pressure at home, weigh themselves, and take their own pulse to give an excellent set of vital signs that will indicate how they are doing, said Dr. Goldberg.

“During a remote visit, we can talk to the patient and notice whether or not they are short of breath or coughing, but we can’t listen to their heart or do an EKG or any of the traditional cardiac testing. Still, for someone who is not having symptoms and is able to reliably monitor their blood pressure and weight, a remote visit is sufficient to give you a good sense of how that patient is doing,” she said. “We can talk to them about their medications, any potential side effects, and we can use their blood pressure information to adjust their medications.”

Many patients are becoming more savvy about using tech gadgets and devices to monitor their health.

“Some of my patients were using Apple watches and the Kardia app to address their heart rate. Many had purchased inexpensive pulse oximeters to check their oxygen during the pandemic, and that also reads the pulse,” Dr. Goldberg said.

In-person visits were reserved for symptomatic cardiac patients, she explained.

“Initially during the pandemic, we did mostly telemedicine visits and we organized the office so that each cardiologist would come in 1 day a week to take care of symptomatic cardiac patients. In that way, we were able to socially distance – they provided us with [personal protective equipment]; at NYU there was no problem with that – and nobody waited in the waiting room. To this day, office issues are more efficient and people are not waiting in the waiting room,” she added. “Telemedicine improves access to health care in populations where such access is limited.”

Dr. Yuan’s research is supported by a grant from the National Institutes of Health. Dr. Goldberg reported no relevant financial relationships.

Dr. Neal Yuan

“The COVID-19 pandemic has led to an unprecedented shift in ambulatory cardiovascular care from in-person to remote visits,” lead author Neal Yuan, MD, a cardiology fellow at the Smidt Heart Institute, Cedars-Sinai Medical Center, Los Angeles, said in an interview.

Their findings were published online April 5 in JAMA Network Open.

“We wanted to explore whether the transition to remote visits was associated with disparities in how patients accessed care, and also how this transition affected diagnostic test ordering and medication prescribing,” Dr. Yuan said.

The researchers used electronic health records data for all ambulatory cardiology visits at an urban, multisite health system in Los Angeles County during two periods: April 1 to Dec. 31, 2019, the pre-COVID era; and April 1 to Dec. 31, 2020, the COVID era.

The investigators compared patient characteristics and frequencies of medication ordering and cardiology-specific testing across four visit types: pre-COVID in person, used as reference; COVID-era in person; COVID-era video; and COVID-era telephone.

The study looked at 176,781 ambulatory cardiology visits. Of these visits, 87,182 were conducted in person in the pre-COVID period; 74,498 were conducted in person in the COVID era; 4,720 were COVID-era video visits; and 10,381 were COVID-era telephone visits.

In the study cohort, 79,572 patients (45.0%) were female, 127,080 patients (71.9%) were non-Hispanic White, and the mean age was 68.1 years (standard deviation, 17.0).

Patients accessing COVID-era remote visits were more likely to be Asian, Black, or Hispanic, to have private insurance, and to have cardiovascular comorbidities, such as hypertension and heart failure.

Also, patients whose visits were conducted by video were significantly younger than patients whose visits were conducted in person or by telephone (P < .001).

In addition, the study found that clinicians ordered fewer diagnostic tests, such as electrocardiograms and echocardiograms, and were less likely to order any medication, in the pre-COVID era than during the COVID era.

“If you don’t have a patient in front of you, it’s much more difficult to get a physical exam or obtain reliable vital signs,” said Dr. Yuan. Communication can sometimes be difficult, often because of technical issues, like a bad connection. “You might be more reticent to get testing or to prescribe medications if you don’t feel confident knowing what the patient’s vital signs are.”

In addition, he added, “a lot of medications used in the cardiology setting require monitoring patients’ kidney function and electrolytes, and if you can’t do that reliably, you might be more cautious about prescribing those types of medications.”
 

An eye-opening study

Cardiologist Nieca Goldberg, MD, medical director of the New York University Langone womens’ heart program and spokesperson for the American Heart Association, recounted her experience with telemedicine at the height of the pandemic in New York, when everything, including medical outpatient offices, had to close.

Dr. Nieca Goldberg

“We were experienced with telemedicine because we had started a virtual urgent care program well ahead of the pandemic,” she said. “We started using that to screen people with potential COVID symptoms so that they wouldn’t have to come into the hospital, the medical center, or to the offices and expose people. We learned that it was great to have the telemedicine option from the infectious disease standpoint, and I did visits like that for my own patient population.”

An equally if not more important finding from the study is the fact that telemedicine increased access to care among traditionally underserved demographics, she said.

“This is eye-opening, that you can actually improve access to care by doing telemedicine visits. It was really important to see that telemedicine has added benefit to the way we can see people in the health care system.”

Telemedicine visits had a positive impact at a time when people were isolated at home, Dr. Goldberg said.

“It was a way for them to connect with their doctor and in some ways it was more personal,” she added. “I actually got to meet some of my patients’ family members. It was like making a remote house call.”

Stable cardiology patients can take their blood pressure at home, weigh themselves, and take their own pulse to give an excellent set of vital signs that will indicate how they are doing, said Dr. Goldberg.

“During a remote visit, we can talk to the patient and notice whether or not they are short of breath or coughing, but we can’t listen to their heart or do an EKG or any of the traditional cardiac testing. Still, for someone who is not having symptoms and is able to reliably monitor their blood pressure and weight, a remote visit is sufficient to give you a good sense of how that patient is doing,” she said. “We can talk to them about their medications, any potential side effects, and we can use their blood pressure information to adjust their medications.”

Many patients are becoming more savvy about using tech gadgets and devices to monitor their health.

“Some of my patients were using Apple watches and the Kardia app to address their heart rate. Many had purchased inexpensive pulse oximeters to check their oxygen during the pandemic, and that also reads the pulse,” Dr. Goldberg said.

In-person visits were reserved for symptomatic cardiac patients, she explained.

“Initially during the pandemic, we did mostly telemedicine visits and we organized the office so that each cardiologist would come in 1 day a week to take care of symptomatic cardiac patients. In that way, we were able to socially distance – they provided us with [personal protective equipment]; at NYU there was no problem with that – and nobody waited in the waiting room. To this day, office issues are more efficient and people are not waiting in the waiting room,” she added. “Telemedicine improves access to health care in populations where such access is limited.”

Dr. Yuan’s research is supported by a grant from the National Institutes of Health. Dr. Goldberg reported no relevant financial relationships.

Six pregnancy complications flag later heart disease risk

Article Type
Changed
Tue, 05/03/2022 - 15:06

Six pregnancy-related complications increase a woman’s risk of developing risk factors for cardiovascular disease (CVD) and subsequently developing CVD, the American Heart Association says in a new scientific statement.

They are hypertensive disorders of pregnancy, preterm delivery, gestational diabetes, small-for-gestational-age (SGA) delivery, placental abruption (abruptio placentae), and pregnancy loss.

A history of any of these adverse pregnancy outcomes should prompt “more vigorous primordial prevention of CVD risk factors and primary prevention of CVD,” the writing group says.

“Adverse pregnancy outcomes are linked to women having hypertension, diabetes, abnormal cholesterol, and cardiovascular disease events, including heart attack and stroke, long after their pregnancies,” Nisha I. Parikh, MD, MPH, chair of the writing group, said in a news release.

Adverse pregnancy outcomes can be a “powerful window” into CVD prevention “if women and their health care professionals harness the knowledge and use it for health improvement,” said Dr. Parikh, associate professor of medicine in the cardiovascular division at the University of California, San Francisco.

The statement was published online March 29 in Circulation.

For the scientific statement, the writing group reviewed the latest scientific literature on adverse pregnancy outcomes and CVD risk. 

The evidence in the literature linking adverse pregnancy outcomes to later CVD is “consistent over many years and confirmed in nearly every study we examined,” Dr. Parikh said. Among their key findings:

  • Gestational hypertension is associated with an increased risk of CVD later in life by 67% and the odds of stroke by 83%. Moderate and severe  is associated with a more than twofold increase in the risk for CVD.
  • Gestational diabetes is associated with an increase in the risk for CVD by 68% and the risk of developing  after pregnancy by 10-fold.
  • Preterm delivery (before 37 weeks) is associated with double the risk of developing CVD and is strongly associated with later heart disease, stroke, and CVD.
  • Placental abruption is associated with an 82% increased risk for CVD.
  • Stillbirth is associated with about double the risk for CVD.

“This statement should inform future prevention guidelines in terms of the important factors to consider for determining women’s risk for heart diseases and stroke,” Dr. Parikh added.

The statement emphasizes the importance of recognizing these adverse pregnancy outcomes when evaluating CVD risk in women but notes that their value in reclassifying CVD risk may not be established.

It highlights the importance of adopting a heart-healthy diet and increasing physical activity among women with any of these pregnancy-related complications, starting right after childbirth and continuing across the life span to decrease CVD risk.

Lactation and breastfeeding may lower a woman’s later cardiometabolic risk, the writing group notes.
 

‘Golden year of opportunity’

The statement highlights several opportunities to improve transition of care for women with adverse pregnancy outcomes and to implement strategies to reduce their long-term CVD risk.

One strategy is longer postpartum follow-up care, sometimes referred to as the “fourth trimester,” to screen for CVD risk factors and provide CVD prevention counseling.

Another strategy involves improving the transfer of health information between ob/gyns and primary care physicians to eliminate inconsistencies in electronic health record documentation, which should improve patient care.

A third strategy is obtaining a short and targeted health history for each woman to confirm if she has any of the six pregnancy-related complications.

“If a woman has had any of these adverse pregnancy outcomes, consider close blood pressure monitoring, type 2 diabetes and lipid screening, and more aggressive risk factor modification and CVD prevention recommendations,” Dr. Parikh advised.

“Our data [lend] support to the prior AHA recommendation that these important adverse pregnancy outcomes should be ‘risk enhancers’ to guide consideration for statin therapy aimed at CVD prevention in women,” Dr. Parikh added.

In a commentary in Circulation, Eliza C. Miller, MD, assistant professor of neurology at Columbia University, New York, notes that pregnancy and the postpartum period are a critical time window in a woman’s life to identify CVD risk and improve a woman’s health trajectory.

“The so-called ‘Golden Hour’ for conditions such as sepsis and acute stroke refers to a critical time window for early recognition and treatment, when we can change a patient’s clinical trajectory and prevent severe morbidity and mortality,” writes Dr. Miller.

“Pregnancy and the postpartum period can be considered a ‘Golden Year’ in a woman’s life, offering a rare opportunity for clinicians to identify young women at risk and work with them to improve their cardiovascular health trajectories,” she notes.

This scientific statement was prepared by the volunteer writing group on behalf of the AHA Council on Epidemiology and Prevention; the Council on Arteriosclerosis, Thrombosis and Vascular Biology; the Council on Cardiovascular and Stroke Nursing; and the Stroke Council.

The authors of the scientific statement have disclosed no relevant financial relationships. Dr. Miller received personal compensation from Finch McCranie and Argionis & Associates for expert testimony regarding maternal stroke; and personal compensation from Elsevier for editorial work on Handbook of Clinical Neurology, Vol. 171 and 172 (Neurology of Pregnancy).

The best exercises for BP control? European statement sorts it out

Article Type
Changed
Tue, 03/30/2021 - 14:09

Recommendations for prescribing exercise to control high blood pressure have been put forward by various medical organizations and expert panels, but finding the bandwidth to craft personalized exercise training for their patients poses a challenge for clinicians.

Dr. Matthew W. Martinez

Now, European cardiology societies have issued a consensus statement that offers an algorithm of sorts for developing personalized exercise programs as part of overall management approach for patients with or at risk of high BP.

The statement, published in the European Journal of Preventive Cardiology and issued by the European Association of Preventive Cardiology and the European Society of Cardiology Council on Hypertension, claims to be the first document to focus on personalized exercise for BP.

The statement draws on a systematic review, including meta-analyses, to produce guidance on how to lower BP in three specific types of patients: Those with hypertension (>140/90 mm Hg), high-normal blood pressure (130-139/85-89 mm Hg), and normal blood pressure (<130/84 mm Hg).

By making recommendations for these three specific groups, along with providing guidance for combined exercise – that is, blending aerobic exercise with resistance training (RT) – the consensus statement goes one step further than recommendations other organizations have issued, Matthew W. Martinez, MD, said in an interview.

“What it adds is an algorithmic approach, if you will,” said Dr. Martinez, a sports medicine cardiologist at Morristown (N.J.) Medical Center. “There are some recommendations to help the clinicians to decide what they’re going to offer individuals, but what’s a challenge for us when seeing patients is finding the time to deliver the message and explain how valuable nutrition and exercise are.”

Guidelines, updates, and statements that include the role of exercise in BP control have been issued by the European Society of Cardiology, American Heart Association, and American College of Sports Medicine (Med Sci Sports Exercise. 2019;51:1314-23).

The European consensus statement includes the expected range of BP lowering for each activity. For example, aerobic exercise for patients with hypertension should lead to a reduction from –4.9 to –12 mm Hg systolic and –3.4 to –5.8 mm Hg diastolic.

The consensus statement recommends the following exercise priorities based on a patient’s blood pressure:

  • Hypertension: Aerobic training (AT) as a first-line exercise therapy; and low- to moderate-intensity RT – equally using dynamic and isometric RT – as second-line therapy. In non-White patients, dynamic RT should be considered as a first-line therapy. RT can be combined with aerobic exercise on an individual basis if the clinician determines either form of RT would provide a metabolic benefit.
  • High-to-normal BP: Dynamic RT as a first-line exercise, which the systematic review determined led to greater BP reduction than that of aerobic training. “Isometric RT is likely to elicit similar if not superior BP-lowering effects as [dynamic RT], but the level of evidence is low and the available data are scarce,” wrote first author Henner Hanssen, MD, of the University of Basel, Switzerland, and coauthors. Combining dynamic resistance training with aerobic training “may be preferable” to dynamic RT alone in patients with a combination of cardiovascular risk factors.
  • Normal BP: Isometric RT may be indicated as a first-line intervention in individuals with a family or gestational history or obese or overweight people currently with normal BP. This advice includes a caveat: “The number of studies is limited and the 95% confidence intervals are large,” Dr. Hanssen and coauthors noted. AT is also an option in these patients, with more high-quality meta-analyses than the recommendation for isometric RT. “Hence, the BP-lowering effects of [isometric RT] as compared to AT may be overestimated and both exercise modalities may have similar BP-lowering effects in individuals with normotension,” wrote the consensus statement authors.

They note that more research is needed to validate the BP-lowering effects of combined exercise.

The statement acknowledges the difficulty clinicians face in managing patients with high blood pressure. “From a socioeconomic health perspective, it is a major challenge to develop, promote, and implement individually tailored exercise programs for patients with hypertension under consideration of sustainable costs,” wrote Dr. Hanssen and coauthors.

Dr. Martinez noted that one strength of the consensus statement is that it addresses the impact exercise can have on vascular health and metabolic function. And, it points out existing knowledge gaps.

“Are we going to see greater applicability of this as we use IT health technology?” he asked. “Are wearables and telehealth going to help deliver this message more easily, more frequently? Is there work to be done in terms of differences in gender? Do men and women respond differently, and is there a different exercise prescription based on that as well as ethnicity? We well know there’s a different treatment for African Americans compared to other ethnic groups.”

The statement also raises the stakes for using exercise as part of a multifaceted, integrated approach to hypertension management, he said.

“It’s not enough to talk just about exercise or nutrition, or to just give an antihypertension medicine,” Dr. Martinez said. “Perhaps the sweet spot is in integrating an approach that includes all three.”

Consensus statement coauthor Antonio Coca, MD, reported financial relationships with Abbott, Berlin-Chemie, Biolab, Boehringer-Ingelheim, Ferrer, Menarini, Merck, Novartis and Sanofi-Aventis. Coauthor Maria Simonenko, MD, reported financial relationships with Novartis and Sanofi-Aventis. Linda Pescatello, PhD, is lead author of the American College of Sports Medicine 2019 statement. Dr. Hanssen and all other authors have no disclosures. Dr. Martinez has no relevant relationships to disclose.

By making recommendations for these three specific groups, along with providing guidance for combined exercise – that is, blending aerobic exercise with resistance training (RT) – the consensus statement goes one step further than recommendations other organizations have issued, Matthew W. Martinez, MD, said in an interview.

“What it adds is an algorithmic approach, if you will,” said Dr. Martinez, a sports medicine cardiologist at Morristown (N.J.) Medical Center. “There are some recommendations to help the clinicians to decide what they’re going to offer individuals, but what’s a challenge for us when seeing patients is finding the time to deliver the message and explain how valuable nutrition and exercise are.”

Guidelines, updates, and statements that include the role of exercise in BP control have been issued by the European Society of Cardiology, American Heart Association, and American College of Sports Medicine (Med Sci Sports Exercise. 2019;51:1314-23).

The European consensus statement includes the expected range of BP lowering for each activity. For example, aerobic exercise for patients with hypertension should lead to a reduction from –4.9 to –12 mm Hg systolic and –3.4 to –5.8 mm Hg diastolic.

The consensus statement recommends the following exercise priorities based on a patient’s blood pressure:

  • Hypertension: Aerobic training (AT) as a first-line exercise therapy; and low- to moderate-intensity RT – equally using dynamic and isometric RT – as second-line therapy. In non-White patients, dynamic RT should be considered as a first-line therapy. RT can be combined with aerobic exercise on an individual basis if the clinician determines either form of RT would provide a metabolic benefit.
  • High-to-normal BP: Dynamic RT as a first-line exercise, which the systematic review determined led to greater BP reduction than that of aerobic training. “Isometric RT is likely to elicit similar if not superior BP-lowering effects as [dynamic RT], but the level of evidence is low and the available data are scarce,” wrote first author Henner Hanssen, MD, of the University of Basel, Switzerland, and coauthors. Combining dynamic resistance training with aerobic training “may be preferable” to dynamic RT alone in patients with a combination of cardiovascular risk factors.
  • Normal BP: Isometric RT may be indicated as a first-line intervention in individuals with a family or gestational history or obese or overweight people currently with normal BP. This advice includes a caveat: “The number of studies is limited and the 95% confidence intervals are large,” Dr. Hanssen and coauthors noted. AT is also an option in these patients, with more high-quality meta-analyses than the recommendation for isometric RT. “Hence, the BP-lowering effects of [isometric RT] as compared to AT may be overestimated and both exercise modalities may have similar BP-lowering effects in individuals with normotension,” wrote the consensus statement authors.

They note that more research is needed to validate the BP-lowering effects of combined exercise.

The statement acknowledges the difficulty clinicians face in managing patients with high blood pressure. “From a socioeconomic health perspective, it is a major challenge to develop, promote, and implement individually tailored exercise programs for patients with hypertension under consideration of sustainable costs,” wrote Dr. Hanssen and coauthors.

Dr. Martinez noted that one strength of the consensus statement is that it addresses the impact exercise can have on vascular health and metabolic function. And, it points out existing knowledge gaps.

“Are we going to see greater applicability of this as we use IT health technology?” he asked. “Are wearables and telehealth going to help deliver this message more easily, more frequently? Is there work to be done in terms of differences in gender? Do men and women respond differently, and is there a different exercise prescription based on that as well as ethnicity? We well know there’s a different treatment for African Americans compared to other ethnic groups.”

The statement also raises the stakes for using exercise as part of a multifaceted, integrated approach to hypertension management, he said.

“It’s not enough to talk just about exercise or nutrition, or to just give an antihypertension medicine,” Dr. Martinez said. “Perhaps the sweet spot is in integrating an approach that includes all three.”

Consensus statement coauthor Antonio Coca, MD, reported financial relationships with Abbott, Berlin-Chemie, Biolab, Boehringer-Ingelheim, Ferrer, Menarini, Merck, Novartis and Sanofi-Aventis.

Recommendations for prescribing exercise to control high blood pressure have been put forward by various medical organizations and expert panels, but finding the bandwidth to craft personalized exercise training for their patients poses a challenge for clinicians.

Now, European cardiology societies have issued a consensus statement that offers an algorithm of sorts for developing personalized exercise programs as part of overall management approach for patients with or at risk of high BP.

Long-haul COVID-19 brings welcome attention to POTS

Article Type
Changed
Thu, 08/26/2021 - 15:49

Before COVID-19, postural orthostatic tachycardia syndrome (POTS) was one of those diseases that many people, including physicians, dismissed.

Dr. Pam R. Taub

“They thought it was just anxious, crazy young women,” said Pam R. Taub, MD, who runs the cardiac rehabilitation program at the University of California, San Diego.

The cryptic autonomic condition was estimated to affect 1-3 million Americans before the pandemic hit. Now case reports confirm that it is a manifestation of postacute sequelae of SARS-CoV-2 infection (PASC), or so-called long-haul COVID-19.

“I’m excited that this condition that has been so often the ugly stepchild of both cardiology and neurology is getting some attention,” said Dr. Taub. She said she is hopeful that the National Institutes of Health’s commitment to PASC research will benefit patients affected by the cardiovascular dysautonomia characterized by orthostatic intolerance in the absence of orthostatic hypotension.

Postinfection POTS is not exclusive to SARS-CoV-2. It has been reported after Lyme disease and Epstein-Barr virus infections, for example. One theory is that some of the antibodies generated against the virus cross react and damage the autonomic nervous system, which regulates heart rate and blood pressure, Dr. Taub explained.

It is not known whether COVID-19 is more likely to trigger POTS than are other infections or whether the rise in cases merely reflects the fact that more than 115 million people worldwide have been infected with the novel coronavirus.

Low blood volume, dysregulation of the autonomic nervous system, and autoimmunity may all play a role in POTS, perhaps leading to distinct subtypes, according to a State of the Science document from the NIH; the National Heart, Lung, and Blood Institute; and the National Institute of Neurological Disorders and Stroke.

In Dr. Taub’s experience, “The truth is that patients actually have a mix of the subtypes.”

Kamal Shouman, MD, an autonomic neurologist at Mayo Clinic, Rochester, Minn., said in an interview that he has seen patients present with post–COVID-19 POTS in “all flavors,” including “neuropathic POTS, which is thought of as the classic postinfectious phenomenon.”

Why does it mostly affect athletic women?

The condition, which can be the result of dehydration or prolonged bed rest, leading to deconditioning, affects women disproportionately.

According to Manesh Patel, MD, if a patient with POTS who is not a young woman is presented on medical rounds, the response is, “Tell me again why you think this patient has POTS.”

Dr. Patel, chief of the division of cardiology at Duke University, Durham, N.C., has a theory for why many of the women who have POTS are athletes or are highly active: They likely have an underlying predisposition, compounded by a smaller body volume, leaving less margin for error. “If they decondition and lose 500 cc’s, it makes a bigger difference to them than, say, a 300-pound offensive lineman,” Dr. Patel explained.

That hypothesis makes sense to Dr. Taub, who added, “There are just some people metabolically that are more hyperadrenergic,” and it may be that “all their activity really helps tone down that sympathetic output,” but the infection affects these regulatory processes, and deconditioning disrupts things further.

Women also have more autoimmune disorders than do men. The driving force of the dysregulation of the autonomic nervous system is thought to be “immune mediated; we think it’s triggered by a response to a virus,” she said.

Dr. Shouman said the underlying susceptibility may predispose toward orthostatic intolerance. For example, patients will tell him, “Well, many years ago, I was prone to fainting.” He emphasized that POTS is not exclusive to women – he sees men with POTS, and one of the three recent case reports of post–COVID-19 POTS involved a 37-year-old man. So far, the male POTS patients that Dr. Patel has encountered have been deconditioned athletes.
 

 

 

Poor (wo)man’s tilt test and treatment options

POTS is typically diagnosed with a tilt test and transcranial Doppler. Dr. Taub described her “poor man’s tilt test” of asking the patient to lie down for 5-10 minutes and then having the patient stand up.

She likes the fact that transcranial Doppler helps validate the brain fog that patients report, which can be dismissed as “just your excuse for not wanting to work.” If blood perfusion to the brain is cut by 40%-50%, “how are you going to think clearly?” she said.

Dr. Shouman noted that overall volume expansion with salt water, compression garments, and a graduated exercise program play a major role in the rehabilitation of all POTS patients.

He likes to tailor treatments to the most likely underlying cause. But patients should first undergo a medical assessment by their internists to make sure there isn’t a primary lung or heart problem.

“Once the decision is made for them to be evaluated in the autonomic practice and [a] POTS diagnosis is made, I think it is very useful to determine what type of POTS,” he said.

With hyperadrenergic POTS, “you are looking at a standing norepinephrine level of over 600 pg/mL or so.” For these patients, drugs such as ivabradine or beta-blockers can help, he noted.

Dr. Taub recently conducted a small study that showed a benefit with the selective If channel blocker ivabradine for patients with hyperadrenergic POTS unrelated to COVID-19. She tends to favor ivabradine over beta-blockers because it lowers heart rate but not blood pressure. In addition, beta-blockers can exacerbate fatigue and brain fog.

small crossover study will compare propranolol and ivabradine in POTS. For someone who is very hypovolemic, “you might try a salt tablet or a prescription drug like fludrocortisone,” Dr. Taub explained.

Another problem that patients with POTS experience is an inability to exercise because of orthostatic intolerance. Recumbent exercise targets deconditioning and can tamp down the hyperadrenergic effect. Dr. Shouman’s approach is to start gradually with swimming or the use of a recumbent bike or a rowing machine.

Dr. Taub recommends wearables to patients because POTS is “a very dynamic condition” that is easy to overmedicate or undermedicate. If it’s a good day, the patients are well hydrated, and the standing heart rate is only 80 bpm, she tells them they could titrate down their second dose of ivabradine, for example. The feedback from wearables also helps patients manage their exercise response.

For Dr. Shouman, wearables are not always as accurate as he would like. He tells his patients that it’s okay to use one as long as it doesn’t become a source of anxiety such that they’re constantly checking it.
 

POTS hope: A COVID-19 silver lining?

With increasing attention being paid to long-haul COVID-19, are there any concerns that POTS will get lost among the myriad symptoms connected to PASC?

Dr. Shouman cautioned, “Not all long COVID is POTS,” and said that clinicians at long-haul clinics should be able to recognize the different conditions “when POTS is suspected. I think it is useful for those providers to make the appropriate referral for POTS clinic autonomic assessment.”

He and his colleagues at Mayo have seen quite a few patients who have post–COVID-19 autonomic dysfunction, such as vasodepressor syncope, not just POTS. They plan to write about this soon.

“Of all the things I treat in cardiology, this is the most complex, because there’s so many different systems involved,” said Dr. Taub, who has seen patients recover fully from POTS. “There’s a spectrum, and there’s people that are definitely on one end of the spectrum where they have very severe diseases.”

For her, the important message is, “No matter where you are on the spectrum, there are things we can do to make your symptoms better.” And with grant funding for PASC research, “hopefully we will address the mechanisms of disease, and we’ll be able to cure this,” she said.

Dr. Patel has served as a consultant for Bayer, Janssen, AstraZeneca, and Heartflow and has received research grants from Bayer, Janssen, AstraZeneca, and the National Heart, Lung, and Blood Institute. Dr. Shouman reports no relevant financial relationships. Dr. Taub has served as a consultant for Amgen, Bayer, Esperion, Boehringer Ingelheim, Novo Nordisk, and Sanofi; is a shareholder in Epirium Bio; and has received research grants from the National Institutes of Health, the American Heart Association, and the Department of Homeland Security/FEMA.

If it’s a good day, the patients are well hydrated, and the standing heart rate is only 80 bpm, she tells them they could titrate down their second dose of ivabradine, for example. The feedback from wearables also helps patients manage their exercise response.

For Dr. Shouman, wearables are not always as accurate as he would like. He tells his patients that it’s okay to use one as long as it doesn’t become a source of anxiety such that they’re constantly checking it.
 

POTS hope: A COVID-19 silver lining?

With increasing attention being paid to long-haul COVID-19, are there any concerns that POTS will get lost among the myriad symptoms connected to PASC?

Dr. Shouman cautioned, “Not all long COVID is POTS,” and said that clinicians at long-haul clinics should be able to recognize the different conditions “when POTS is suspected. I think it is useful for those providers to make the appropriate referral for POTS clinic autonomic assessment.”

He and his colleagues at Mayo have seen quite a few patients who have post–COVID-19 autonomic dysfunction, such as vasodepressor syncope, not just POTS. They plan to write about this soon.

“Of all the things I treat in cardiology, this is the most complex, because there’s so many different systems involved,” said Dr. Taub, who has seen patients recover fully from POTS. “There’s a spectrum, and there’s people that are definitely on one end of the spectrum where they have very severe diseases.”

For her, the important message is, “No matter where you are on the spectrum, there are things we can do to make your symptoms better.” And with grant funding for PASC research, “hopefully we will address the mechanisms of disease, and we’ll be able to cure this,” she said.

Dr. Patel has served as a consultant for Bayer, Janssen, AstraZeneca, and Heartflow and has received research grants from Bayer, Janssen, AstraZeneca, and the National Heart, Lung, and Blood Institute. Dr. Shouman reports no relevant financial relationships. Dr. Taub has served as a consultant for Amgen, Bayer, Esperion, Boehringer Ingelheim, Novo Nordisk, and Sanofi; is a shareholder in Epirium Bio; and has received research grants from the National Institutes of Health, the American Heart Association, and the Department of Homeland Security/FEMA.

Blood pressure meds tied to increased schizophrenia risk

Article Type

Wed, 03/24/2021 - 11:47

ACE inhibitors may be associated with an increased risk for schizophrenia and may affect psychiatric symptoms, new research suggests.

Dr. Sonia Shah

Investigators found individuals who carry a genetic variant associated with lower levels of the ACE gene and protein have increased liability to schizophrenia, suggesting that drugs that lower ACE levels or activity may do the same.

“Our findings warrant further investigation into the role of ACE in schizophrenia and closer monitoring by clinicians of individuals, especially those with schizophrenia, who may be on medication that lower ACE activity, such as ACE inhibitors,” Sonia Shah, PhD, Institute for Biomedical Sciences, University of Queensland, Brisbane, Australia, said in an interview.

The study was published online March 10, 2021, in JAMA Psychiatry.
 

Antihypertensives and mental illness

Hypertension is common in patients with psychiatric disorders and observational studies have reported associations between antihypertensive medication and these disorders, although the findings have been mixed.

Dr. Shah and colleagues estimated the potential of different antihypertensive drug classes on schizophrenia, bipolar disorder, and major depressive disorder.

In a two-sample Mendelian randomization study, they evaluated ties between a single-nucleotide variant and drug-target gene expression derived from expression quantitative trait loci data in blood (sample 1) and the SNV disease association from published case-control, genomewide association studies (sample 2).

The analyses included 40,675 patients with schizophrenia and 64,643 controls; 20,352 with bipolar disorder and 31,358 controls; and 135,458 with major depressive disorder and 344,901 controls.

The major finding was that a one standard deviation–lower expression of the ACE gene in blood was associated with lower systolic blood pressure of 4.0 mm Hg (95% confidence interval, 2.7-5.3), but also an increased risk of schizophrenia (odds ratio, 1.75; 95% CI, 1.28-2.38).
 

Could ACE inhibitors worsen symptoms or trigger episodes?

In their article, the researchers noted that, in most patients, onset of schizophrenia occurs in late adolescence or early adult life, ruling out ACE inhibitor treatment as a potential causal factor for most cases.

“However, if lower ACE levels play a causal role for schizophrenia risk, it would be reasonable to hypothesize that further lowering of ACE activity in existing patients could worsen symptoms or trigger a new episode,” they wrote.

Dr. Shah emphasized that evidence from genetic analyses alone is “not sufficient to justify changes in prescription guidelines.”

“Patients should not stop taking these medications if they are effective at controlling their blood pressure and they don’t suffer any adverse effects. But it would be reasonable to encourage greater pharmacovigilance,” she said in an interview.

“One way in which we are hoping to follow up these findings,” said Dr. Shah, “is to access electronic health record data for millions of individuals to investigate if there is evidence of increased rates of psychotic episodes in individuals who use ACE inhibitors, compared to other classes of blood pressure–lowering medication.”
 

Caution warranted

Reached for comment, Timothy Sullivan, MD, chair of psychiatry and behavioral sciences at Staten Island University Hospital in New York, noted that this is an “extremely complicated” study and urged caution in interpreting the results.

“Since most people develop schizophrenia earlier in life, before they usually develop problems with blood pressure, it’s not so much that these drugs might cause schizophrenia,” Dr. Sullivan said.

“But because of their effects on this particular gene, there’s a possibility that they might worsen symptoms or in somebody with borderline risk might cause them to develop symptoms later in life. This may apply to a relatively small number of people who develop symptoms of schizophrenia in their 40s and beyond,” he added.

That’s where “pharmacovigilance” comes into play, Dr. Sullivan said. “In other words, we should be looking at people we’re treating with these drugs to see – might we be tipping some of them into illness states that they otherwise wouldn’t experience?”

Support for the study was provided by the National Health and Medical Research Council (Australia) and U.S. National Institute for Mental Health. Dr. Shah and Dr. Sullivan disclosed no relevant financial relationships.

Imaging alternative to AVS could boost detection of primary aldosteronism

Article Type
Changed
Sun, 03/21/2021 - 13:30

 

A noninvasive imaging method for identifying whether the source of a patient’s primary aldosteronism is from unilateral or bilateral adrenal adenomas worked as well as the standard method, invasive adrenal vein sampling, in a head-to-head comparison with 143 patients.

Dr. David D'Allesio
The findings establish that the imaging technique, which radioactively tags aldosterone-producing tissue with the marker 11C-metomidate followed by PET-CT imaging, “is just as good” as adrenal vein sampling (AVS), declared Xilin Wu, MBBS, during a presentation at the annual meeting of the Endocrine Society.

This noninvasive alternative, which also does not require the substantial technical expertise that AVS demands, should make assessment of adenoma laterality in patients with primary aldosteronism (PA) much more widely available and accessible, predicted Dr. Wu, a researcher at Queen Mary University of London.

“It will allow more places to do this, and I think it will definitely allow more patients to be diagnosed” with PA from a unilateral source. AVS “is a real bottleneck,” she said. “We hope metomidate, or molecular imaging using other selective radiotracers, will enable many more patients to be diagnosed and appropriately managed.” Creating new diagnostic options for patients with PA and potentially increasing the number of these patients who are surgical candidates “is the aim of this study.”

Patients with PA develop a curable form of hypertension if their excess aldosterone can be neutralized with a mineralocorticoid receptor antagonist (MRA), or even more definitively by surgical removal of the adrenal aldosteronoma generating the hormonal excess as long as the adenoma is unilateral. Conventional imaging of the adrenals with CT or MRI has proven unreliable for identifying adrenal nodules noninvasively, which has made the invasive and technically challenging standard option of AVS the only game in town.

But some endocrinologists caution that the results from this one study do not suffice to make 11C-metomidate-based PET-CT imaging a widely used alternative.
 

‘This is a first step.’

“This study is a first step. It will take lots more data for endocrinologists to buy into a scan over AVS,” commented David A. D’Alessio, MD, professor and chief of the division of endocrinology and metabolism at Duke University in Durham, N.C.

But Dr. D’Alessio also acknowledged the clear benefits from a safe and effective alternative to AVS.

“A reliable, less invasive, and less technical means of lateralizing excess aldosterone production would increase the number of people [with a unilateral PA source] going to surgery. The reality is that, if you are not a patient at the Mayo Clinic . . .or the National Institutes of Health, then AVS is a bit of crap shoot” that is very operator and institution dependent for its accuracy, Dr. D’Alessio said in an interview.

Metomidate specifically binds to key enzymes of the adrenal corticosteroid biosynthetic pathway, making it a precise targeting agent for a radioactive tag as documented almost a decade ago. One limitation is that this radiotracer labeling of metomidate has a 20-minute half life, which means it must be produced on site, thereby making the technology out of reach for locations that can’t set up this capability.

 

 

MATCHing imaging against AVS

To test the clinical utility of metomidate-based PET-CT directly against AVS, Dr. Wu and her associates enrolled 143 adults with confirmed PA and hypertension at two centers in London and one in Cambridge, England. The MATCH study cohort averaged 53 years of age; two-thirds were men, 58% were White, and 30% were Black. Their median blood pressure was 147/91 mm Hg, and they were maintained on a median of two antihypertensive drugs.

The researchers assessed every patient with both the imaging method and AVS, performed in random order and blindly scored. They then began each patient on a 1-month regimen with an MRA (usually spironolactone but eplerenone [Inspra] was also an option) to test the responsiveness of each patient’s hypertension to this drug class and to gauge their likely response to adrenalectomy. After the MRA test, the researchers assessed the lateralization tests and determined that 78 patients were appropriate candidates for unilateral adrenalectomy while the remaining 65 patients were not and continued on the MRA regimen. They recommended surgery if patients were clear positives by AVS, by PET-CT imaging, or both.

The study had four primary outcomes to assess the ability of the two diagnostic methods to predict the success of surgery based on four increasingly stringent postsurgical criteria calculated in hierarchical sequence: Partial or complete biochemical success, complete biochemical success, partial or complete clinical success (partial meaning any significant reduction in blood pressure), or complete clinical success (systolic pressure reduced to less than 135 mm Hg). Only one of the 78 patients treated with surgery failed to achieve at least a partial biochemical response.

For each of the four metrics, 11C-metomidate PET-CT produced point estimates of diagnostic accuracy that consistently edged out AVS. While these advantages were not large enough to meet the prespecified threshold for proving superiority, they comfortably showed the noninferiority of this imaging method compared with AVS.

For example, the PET-CT method had 43.6% accuracy for predicting a clinical cure, compared with 39.7% accuracy for AVS. For complete biochemical cure, imaging had 68.8% accuracy, compared with 62.3% for AVS, Dr. Wu reported.

Another notable finding from the study was how strongly a robust blood pressure response to spironolactone predicted the clinical outcome from surgery. Patients whose systolic blood pressure fell below 135 mm Hg on MRA treatment had a nearly 18-fold higher rate of achieving a complete clinical cure following surgery compared with patients who did not have as dramatic a blood pressure response to MRA treatment.

Woefully low rates of PA assessment

But regardless of the success that PET-CT imaging has for identifying surgical candidates, the first step is to identify patients with PA, a diagnosis that’s woefully underperformed worldwide. One example: A separate report at ENDO 2021 retrospectively reviewed nearly 12,000 patients with hypertension and an indication of PA, such as treatment-resistant hypertension or early-onset hypertension, and managed at either of two university outpatient clinics in Michigan during 2010-2019. The report documented that 3% underwent PA assessment.

Diagnosis of patients with PA “is a major problem,” noted Dr. D’Alessio. “I think of PA as an underdiagnosed and undertreated condition, with a huge impact on morbidity and mortality. Any advance in this area is likely to be useful.” But, he added, “I’m dubious whether this [new imaging approach] will increase diagnosis of PA.” What’s needed is “getting more primary care physicians to do more screening” for PA among their patients with hypertension and a suggestion of a PA cause.

“Surgical cures are glamorous, but medical management is also very effective, and we have good, inexpensive drugs to do this,” the MRAs, Dr. D’Alessio said.

The study received no commercial funding. Dr. Wu and her coauthors had no disclosures. Dr. D’Alessio has been a speaker on behalf of Novo Nordisk, a consultant to Intarcia and Lilly, and has received research funding from Lilly and Merck.

After the MRA test, the researchers assessed the lateralization tests and determined that 78 patients were appropriate candidates for unilateral adrenalectomy while the remaining 65 patients were not and continued on the MRA regimen. They recommended surgery if patients were clear positives by AVS, by PET-CT imaging, or both.

The study had four primary outcomes to assess the ability of the two diagnostic methods to predict the success of surgery based on four increasingly stringent postsurgical criteria calculated in hierarchical sequence: Partial or complete biochemical success, complete biochemical success, partial or complete clinical success (partial meaning any significant reduction in blood pressure), or complete clinical success (systolic pressure reduced to less than 135 mm Hg). Only one of the 78 patients treated with surgery failed to achieve at least a partial biochemical response.

For each of the four metrics, 11C-metomidate PET-CT produced point estimates of diagnostic accuracy that consistently edged out AVS. While these advantages were not large enough to meet the prespecified threshold for proving superiority, they comfortably showed the noninferiority of this imaging method compared with AVS.

For example, the PET-CT method had 43.6% accuracy for predicting a clinical cure, compared with 39.7% accuracy for AVS. For complete biochemical cure, imaging had 68.8% accuracy, compared with 62.3% for AVS, Dr. Wu reported.

Another notable finding from the study was how strongly a robust blood pressure response to spironolactone predicted the clinical outcome from surgery. Patients whose systolic blood pressure fell below 135 mm Hg on MRA treatment had a nearly 18-fold higher rate of achieving a complete clinical cure following surgery compared with patients who did not have as dramatic a blood pressure response to MRA treatment.

Woefully low rates of PA assessment

But regardless of the success that PET-CT imaging has for identifying surgical candidates, the first step is to identify patients with PA, a diagnosis that’s woefully underperformed worldwide. One example: A separate report at ENDO 2021 retrospectively reviewed nearly 12,000 patients with hypertension and an indication of PA, such as treatment-resistant hypertension or early-onset hypertension, and managed at either of two university outpatient clinics in Michigan during 2010-2019. The report documented that 3% underwent PA assessment.

Diagnosis of patients with PA “is a major problem,” noted Dr. D’Alessio. “I think of PA as an underdiagnosed and undertreated condition, with a huge impact on morbidity and mortality. Any advance in this area is likely to be useful.” But, he added, “I’m dubious whether this [new imaging approach] will increase diagnosis of PA.” What’s needed is “getting more primary care physicians to do more screening” for PA among their patients with hypertension and a suggestion of a PA cause.

“Surgical cures are glamorous, but medical management is also very effective, and we have good, inexpensive drugs to do this,” the MRAs, Dr. D’Alessio said.

The study received no commercial funding. Dr. Wu and her coauthors had no disclosures. Dr. D’Alessio has been a speaker on behalf of Novo Nordisk, a consultant to Intarcia and Lilly, and has received research funding from Lilly and Merck.
