Practicing the meditative, rhythmic flow of tai chi works just as well as aerobic exercise and strength training for achieving some health benefits such as reducing waist size and improving cholesterol, new findings suggest.

Results of a randomized controlled trial published online May 31 in Annals of Internal Medicine show that people who have a tough time with some kinds of aerobic exercise may gain similar benefits from tai chi.

The study is “very impressive,” said Bavani Nadeswaran, MD, of the University of California Irvine’s Susan Samueli Integrative Health Institute, who was not involved in the study.

Many people have arthritis or back pain, “and aerobic exercise can be hard on them,” she said. “The good thing about exercises like tai chi and yoga is that they are low-impact.” That means that people who can’t run or get access to a pool for swimming have a viable alternative.

The study included nearly 550 adults ages 50 and up in Hong Kong who were randomly assigned to engage in tai chi, aerobic exercise with strength training, or no exercise program for 12 weeks. All had waistlines greater than 35.4 inches for men and 31.5 inches for women.

The tai chi program involved three 1-hour weekly sessions of the practice, led by an instructor. Those who took part in the aerobic exercise group engaged three times each week in an exercise program of brisk tai chi and strength training, also led by an instructor.

The researchers measured changes in waistline size, cholesterol levels, and weight for about 9 months. Those who didn’t exercise had little change in their average waistline. Compared to the group that didn’t exercise, the average waistline of people in the two exercise groups declined more: by 0.7 inches more with tai chi, and 0.5 inches more with brisk walking and strength training.

Both exercise groups also had greater drops in body weight and triglyceride (a type of fat found in the blood) levels, and larger increases in high-density lipoprotein cholesterol, the “good” cholesterol, compared to the no-exercise group. All of these improvements lasted about 9 months with tai chi. But improvements in cholesterol levels did not last as long in those in the brisk-walking program.

The researchers also looked at the effects on blood pressure and blood sugar, but they found no differences between the groups.

The findings don’t necessarily mean that people with larger waistlines should dispense with their current exercise programs and turn to tai chi, said study author Parco Siu, PhD, head of the Division of Kinesiology at the University of Hong Kong’s School of Public Health. They show that tai chi is a good option if a person prefers it.

“This is good news for middle-aged and older adults who may be averse to conventional exercise,” he said in an email. But “certainly it is no problem for people to keep regularly participating in conventional exercise.”

Tai chi may also be a good choice for people without larger waistlines because practicing this form of exercise is a way to follow advice from the World Health Organization on physical activity, said Dr. Siu, though the study did not address this question.

Dr. Siu and the other researchers noted several limits to the study, including that all the people who took part were in China, so how the practice would affect people in different regions is not clear. Also, almost a third of those who began the study dropped out before it ended, and they tended to have a higher body weight than those who remained to the end. The authors said this high dropout rate could mean that some people had negative experiences during their exercise programs.

Next steps, said Dr. Siu, include further assessing how tai chi affects things such as blood sugar and blood pressure. Other, early-stage studies also show tai chi having some positive effects on mood and cognition, he said, pointing to a need for more research.

UC Irvine’s Dr. Nadeswaran agreed. The work opens the door, she said, to taking a long-term look at how practicing tai chi might affect a person’s risk of dying from heart disease or another cause. Her team’s work involves evaluating tai chi’s effects on several conditions, including metabolic syndrome and even the aftermath of COVID-19.

While researchers pursue these questions, tai chi is accessible in many ways. Dr. Siu noted the availability of classes in this “meditation in motion” practice at community centers and fitness clubs. For people who can’t yet rejoin activities in the real world, Dr. Nadeswaran said virtual tai chi classes also are available.

With the COVID-19 pandemic, already high rates of suicide, depression, and burnout among physicians became even more acute. Yet, 3 years after the Federation of State Medical Boards issued recommendations on what questions about mental health status license applications should – or mostly should not – include, only North Carolina fully complies with all four recommendations, and most states comply with two or fewer, a study of state medical board applications has found (JAMA. 2021 May 18;325[19];2017-8).

Questions about mental health history or “its hypothetical effect on competency,” violate the Americans with Disabilities Act, the study authors stated. In a research letter to JAMA, the authors also reported that five state boards do not comply with any of the FSMB recommendations. Twenty-four states comply with three of the four recommendations.

Overall, the mean consistency score was 2.1, which means state medical licensing applications typically run afoul of the Americans With Disabilities Act when it comes to mental health history of applicants.

“No one should ever wonder, ‘Will I lose my job, or should I get help?’ ” said co–senior author Jessica A. Gold, MD, MS, a psychiatrist at Washington University in St. Louis. “This should absolutely never be a question on someone’s mind. And the fact that it is, in medicine, is a problem that needs to be solved. I hope that people are beginning to see that, and we can make a change to get people the help they need before it is too late.”
 

High rates of depression, suicide

She noted that before COVID-19, physicians already had higher rates of depression, burnout, and suicide than the general population. “Over COVID-19, it has become clear that the mental health of physicians has become additionally compounded,” Dr. Gold said.

One study found that physicians had a 44% higher rate of suicide (PLoS One. 2019 Dec;14[12]:e0226361), but they’re notoriously reluctant to seek out mental health care. A 2017 study reported that 40% of physicians would be reluctant to seek mental health care because of concerns about their licensure (Mayo Clin Proc. 2017;92[10]:1486-93).

As the pandemic went on, Dr. Gold and her colleagues decided to study whether state boards had improved their compliance with the FSMB recommendations issued in 2018. Those recommendations include these four limitations regarding questions about mental health conditions on license applications:

• Include only when they result in impairment.
• Include only when the mental health conditions are current – that is, when they’ve occurred within the past 2 years.
• Provide safe haven nonreporting – that is, allow physicians to not report previously diagnosed and treated mental health conditions if they’re being monitored and are in good standing with a physician health program.
• Include supportive or nonjudgmental language about seeking mental health care.

The study considered board applications that had questions about mental health status as consistent with the first three recommendations. Seventeen states complied.

Thirty-nine state boards complied with the first recommendation regarding impairment; 41 with the second recommendation about near-term history; 25 with safe-haven nonreporting. Only eight states were consistent with the recommendation on supportive language.

The ADA limits inquiries about an applicant’s impairment to only current conditions. In a 2017 study, only 21 state boards had limited questions to current impairment. “This is a significant improvement, but this still means the rest of the states are violating an actual law,” Dr. Gold said. “Another plus is that 17 states asked no questions at all that could require mental health disclosure. This, too is significant because it highlights change in thinking.”

But still, the fact that five states didn’t comply with any recommendation and only one followed all of them is “utterly unacceptable,” Dr. Gold said. “Instead, we should have universal adoption of FSMB recommendations.”
 

Time to remove stigma

Michael F. Myers, MD, a clinical psychiatrist at the State University of New York, Brooklyn, said removing the stigma of seeking help for mental health conditions is especially important for physicians. He’s written several books about physician mental health, including his latest, “Becoming a Doctor’s Doctor: A Memoir.”

“I would say at least 15% of the families that I interviewed who lost a physician loved one to suicide have said the doctor was petrified of going for professional help because of fears of what this could do to their medical license,” he said. “It is extremely important that those licensing questions will be either brought up to speed, or ­– the ones that are clearly violating the ADA – that they be removed.”

Applications for hospital privileges can also run afoul of the same ADA standard, Dr. Myers added. “Physicians have told me that when they go to get medical privileges at a medical center, they get asked all kinds of questions that are outdated, that are intrusive, that violate the ADA,” he said.

Credentialing is another area that Dr. Gold and her colleagues are interested in studying, she said. “Sometimes the licensing applications can be fine, but then the hospital someone is applying to work at can ask the same illegal questions anyway,” she said. “So it doesn’t matter that the state fixed the problem because the hospital asked them anyway. You feel your job is at risk in the same way, so you still don’t get help.”

Dr. Gold and Dr. Myers have no relevant financial relationships to disclose.

Hemoglobin A1c above 5% but below the prediabetes cutoff of 5.5% is an additional potential biomarker of subclinical atherosclerosis in people with low cardiovascular disease risk, according to an analysis of data on almost 4,000 middle-aged individuals.

Mount Sinai Heart/CCA 3.0

“If one looks at the incidence of generalized subclinical atherosclerosis, we are not talking small numbers,” senior study author Valentin Fuster, MD, PhD, said in an interview. “We are talking about between 45% and 82% of this middle-age population that already has atherosclerotic disease subclinically.

“Actually,” he added, “the disease was extensive in 5%-30% of these individuals of middle age.”

The study included 3,973 participants from the Progression of Early Subclinical Atherosclerosis study who did not have diabetes. A1c showed an association with the prevalence and multiterritorial extent of subclinical atherosclerosis as measured by two-dimensional ultrasound and coronary artery calcium score (CACS; P < .001). For example, those with A1c above 6.1% (133 participants) had a 33.1% rate of generalized subclinical atherosclerosis, compared with 4.9% for those with A1c below 4.8% (243), the lowest-score group in the study.

Patients in the subprediabetes band, between 5.0% and 5.5%, had significantly higher rates of generalized subclinical atherosclerosis than did the lowest-score group: 8% in the 4.9%-5.0% group (375 participants); 9.9% in the 5.1%-5.2% range (687); 10.3% in the 5.3%-5.4% group (928); and 11.5% in the 5.5%-5.6% group (842).

Those in the 5.1%-5.2% and 5/3%-5.4% A1c groups had a 27% greater chance of having subclinical atherosclerosis, while those in the 5.5%-5.6% group had a 36% greater risk, according to an odds ratio analysis adjusted for established cardiovascular risk factors. The risks were even higher for patients with prediabetes, the researchers reported in the Journal of the American College of Cardiology.
 

A call for earlier intervention

Notably, the study found that fasting plasma glucose testing did not yield a similar association between A1c and atherosclerosis.

“The message is that we all talk about people when they are close to the development of cardiovascular events, and here we are talking about people who we should pay attention to much earlier,” said Dr. Fuster, physician-in-chief at Icahn School of Medicine at Mount Sinai in New York and director of the National Center for Cardiovascular Investigation in Madrid, where the observational study originated said. “People should be sensitized to HbA1c much more than they would’ve been in the past, and I think this study actually validates that.”

Christie Ballantyne, MD, noted in an interview that these findings support the utility of A1c for predicting CVD risk.

“I think more and more we should be ordering a HbA1c” during routine physical exams, Dr. Ballantyne said. “You don’t have to be obese to get it; there are lots of people, maybe they’re slightly overweight. It’s a reasonable test to be getting when you get to middle age and older to get an idea for assessing for both developing diabetes and also the presence of atherosclerosis and the risk for having cardiovascular events.”

Dr. Ballantyne, chief of cardiology at Baylor College of Medicine and director of cardiovascular disease prevention at Methodist DeBakey Heart Center in Houston, coauthored an editorial comment on the study.

Clinicians typically start to manage CVD and diabetes risk “late in the process,” Dr. Ballantyne said. This study suggested that earlier use of antidiabetes therapies, namely peptide-1 agonists and semisynthetic glucagon-like peptide-2 inhibitors, may be warranted in patients with intermediate risk of CVD.

“It’s just more data for the rationale that, perhaps we could end up doing trials to show we can take high-risk people and prevent them from getting both heart disease and diabetes,” Dr. Ballantyne added. “Could we start a little earlier with better precision?”

These finding don’t yet call for a change in how cardiologists and endocrinologists manage patients on the cusp of prediabetes, said Paul S. Jellinger, MD, of Hollywood, Fla., and a professor at the University of Miami. “The endpoint of subclinical atherosclerosis does not necessarily translate into the harder endpoint of CVD events, although there is certainly reason to believe it does,” he said in an interview, noting that he’s often used CACS to stratify atherosclerotic CVD risk in patients.

Hemoglobin A1c above 5% but below the prediabetes cutoff of 5.5% is an additional potential biomarker of subclinical atherosclerosis in people with low cardiovascular disease risk, according to an analysis of data on almost 4,000 middle-aged individuals.

A1c showed an association with the prevalence and multiterritorial extent of subclinical atherosclerosis as measured by two-dimensional ultrasound and coronary artery calcium score (CACS; P < .001). For example, those with A1c above 6.1% (133 participants) had a 33.1% rate of generalized subclinical atherosclerosis, compared with 4.9% for those with A1c below 4.8% (243), the lowest-score group in the study.

Patients in the subprediabetes band, between 5.0% and 5.5%, had significantly higher rates of generalized subclinical atherosclerosis than did the lowest-score group: 8% in the 4.9%-5.0% group (375 participants); 9.9% in the 5.1%-5.2% range (687); 10.3% in the 5.3%-5.4% group (928); and 11.5% in the 5.5%-5.6% group (842).

Those in the 5.1%-5.2% and 5/3%-5.4% A1c groups had a 27% greater chance of having subclinical atherosclerosis, while those in the 5.5%-5.6% group had a 36% greater risk, according to an odds ratio analysis adjusted for established cardiovascular risk factors. The risks were even higher for patients with prediabetes, the researchers reported in the Journal of the American College of Cardiology.
 

A call for earlier intervention

Notably, the study found that fasting plasma glucose testing did not yield a similar association between A1c and atherosclerosis.

“The message is that we all talk about people when they are close to the development of cardiovascular events, and here we are talking about people who we should pay attention to much earlier,” said Dr. Fuster, physician-in-chief at Icahn School of Medicine at Mount Sinai in New York and director of the National Center for Cardiovascular Investigation in Madrid, where the observational study originated said. “People should be sensitized to HbA1c much more than they would’ve been in the past, and I think this study actually validates that.”

Christie Ballantyne, MD, noted in an interview that these findings support the utility of A1c for predicting CVD risk.

“I think more and more we should be ordering a HbA1c” during routine physical exams, Dr. Ballantyne said. “You don’t have to be obese to get it; there are lots of people, maybe they’re slightly overweight. It’s a reasonable test to be getting when you get to middle age and older to get an idea for assessing for both developing diabetes and also the presence of atherosclerosis and the risk for having cardiovascular events.”

Dr. Ballantyne, chief of cardiology at Baylor College of Medicine and director of cardiovascular disease prevention at Methodist DeBakey Heart Center in Houston, coauthored an editorial comment on the study.

Clinicians typically start to manage CVD and diabetes risk “late in the process,” Dr. Ballantyne said. This study suggested that earlier use of antidiabetes therapies, namely peptide-1 agonists and semisynthetic glucagon-like peptide-2 inhibitors, may be warranted in patients with intermediate risk of CVD.

“It’s just more data for the rationale that, perhaps we could end up doing trials to show we can take high-risk people and prevent them from getting both heart disease and diabetes,” Dr. Ballantyne added. “Could we start a little earlier with better precision?”

These finding don’t yet call for a change in how cardiologists and endocrinologists manage patients on the cusp of prediabetes, said Paul S. Jellinger, MD, of Hollywood, Fla., and a professor at the University of Miami. “The endpoint of subclinical atherosclerosis does not necessarily translate into the harder endpoint of CVD events, although there is certainly reason to believe it does,” he said in an interview, noting that he’s often used CACS to stratify atherosclerotic CVD risk in patients.

Hemoglobin A1c above 5% but below the prediabetes cutoff of 5.5% is an additional potential biomarker of subclinical atherosclerosis in people with low cardiovascular disease risk, according to an analysis of data on almost 4,000 middle-aged individuals.

“If one looks at the incidence of generalized subclinical atherosclerosis, we are not talking small numbers,” senior study author Valentin Fuster, MD, PhD, said in an interview. “We are talking about between 45% and 82% of this middle-age population that already has atherosclerotic disease subclinically.

Taking more steps each day, in short spurts or longer bouts, was associated with a longer life in women older than 60 years, according to data from more than 16,000 participants in the ongoing Women’s Health Study.

The American Heart Association recommends at least 150 minutes per week of moderate physical activity, 75 minutes of vigorous physical activity, or a combination of both as fitness guidelines for adults. Walking is a safe and easy way for many adults to follow these guidelines, according to Christopher C. Moore, MS, a PhD candidate at the University of North Carolina at Chapel Hill.

The popularity of step counts reflect that they are simple and objective, and “focusing on steps can help promote an active lifestyle,” he said. Data on the impact of sporadic steps accumulated outside of longer bouts of activity on health outcomes are limited; however, technology advances in the form of fitness apps and wearable devices make it possible for researchers to track and measure the benefits of short periods of activity as well as longer periods.

In a study presented at the Epidemiology and Prevention/Lifestyle and Cardiometabolic Health meeting, sponsored by the AHA, Mr. Moore and colleagues assessed data from women older than 60 years who used wearable step-counting devices to measure their daily steps and walking patterns.

The study population included 16,732 women enrolled in the Women’s Health Study, a longstanding study of heart disease, cancer, and disease prevention among women in the United States. The participants wore waist step counters 4-7 days a week during 2011-2015. The average of the women was 72 years; 96% were non-Hispanic White, and the average BMI was 26 kg/m².

The researchers divided the total number of steps for each study participant into two groups: “bouted” steps, defined as 10 minutes or longer bouts of walking with few interruptions; and “sporadic” steps, defined as short spurts of walking during regular daily activities such as housework, taking the stairs, or walking to or from a car.

A total of 804 deaths occurred during an average of 6 years of follow-up. Each initial increase of 1,000 steps including sporadic or bouted steps was associated with a 28% decrease in death, compared with no daily steps (hazard ratio, 0.72).

Each increasing quartile of sporadic steps was linked with higher total steps per day, Mr. Moore said. “Initial increase in sporadic steps corresponded to the greatest reductions in mortality,” with a HR of 0.69 per additional sporadic steps below 3,200 per day, and the impact on reduced mortality plateaued at about 4,500 sporadic steps per day.

In further analysis, the researchers also found a roughly 32% decrease in death in participants who took more than 2,000 steps daily in uninterrupted bouts (HR, 0.69).

The study findings were limited by several factors, including the relatively short follow-up period and number of events, the assessment of steps at a single time point, and the mostly homogeneous population, Mr. Moore noted. Additional research is needed to assess whether the results are generalizable to men, younger women, and diverse racial and ethnic groups.

However, the results may have implications for public health messaging, he emphasized. The message is that, to impact longevity, the total volume of steps is more important than the type of activity through which they are accumulated.

“You can accumulate your steps through longer bouts of purposeful activity or through everyday behaviors such as walking to your car, taking the stairs, and doing housework,” Mr. Moore concluded.

Find a friend, both of you benefit

On the basis of this study and other available evidence, more steps daily are recommended for everyone, Nieca Goldberg, MD, a cardiologist at New York University Langone Health, said in an interview.

“You can increase minutes of walking and frequency of walking,” she said.

Dr. Goldberg emphasized that you don’t need a fancy app or wearable device to up your steps. She offered some tips to help overcome barriers to putting one foot in front of the other. “Take the steps instead of the elevator. Park your car farther from your destination so you can walk.” Also, you can help yourself and help a friend to better health. “Get a walking buddy so you can encourage each other to walk,” Dr. Goldberg added.

Mr. Moore and Dr. Goldberg had no financial conflicts to disclose. The Women’s Health Study is funded by Brigham and Women’s Hospital; the National Heart, Lung, and Blood Institute; and the National Cancer Institute. Mr. Moore was funded by a grant from the NHLBI but had no other financial conflicts to disclose.

Anti–apolipoprotein A-I (apo A-I) antibodies are common in nonalcoholic fatty liver disease and may not only drive its development but also underlie the link between NAFLD and cardiovascular disease, suggests a novel analysis.

Conducting a clinical analysis and a series of experiments, Sabrina Pagano, PhD, diagnostic department, Geneva University Hospital, and colleagues looked for anti–apo A-I antibodies in patients with NAFLD and then examined their impact on hepatic cells and inflammatory markers.

They found that nearly half of 137 patients with NAFLD were seropositive, and that the antibodies were associated with increased lipid accumulation in the liver, altered triglyceride metabolism, and proinflammatory effects on liver cells.

“We hypothesize that anti–apo A-I IgG may be a potential driver in the development of NAFLD, and further studies are needed to support anti–apo A-I IgG as a possible link between NAFLD and cardiovascular disease,” Dr. Pagano said.

The research was presented at the European Atherosclerosis Society 2021 Virtual Congress.

Asked whether anti–apo A-I antibodies could represent a potential treatment target for NAFLD, Dr. Pagano said in an interview that they have “already developed a peptide that is recognized by the antibodies in order to try to reverse the anti–apo A-I deleterious effect.”

While this was successful in vitro, “unfortunately we didn’t observe ... the peptide reverse of these anti–apo A-I effects in mice, so ... for the moment it’s a little early,” to say whether it represents a promising target.

Approached for comment, Maciej Banach, MD, PhD, full professor of cardiology, Polish Mother’s Memorial Hospital Research Institute, Lodz, said that the results are “very interesting and encouraging.”

He said that his own global burden of disease analysis, which is set to be published soon, showed that the worldwide prevalence of NAFLD is 11%, “representing almost 900 million cases,” and a more than 33% increase in prevalence in the past 30 years.

Consequently, any “attempt to have effective, especially early, diagnosis and treatment,” is highly anticipated.

Dr. Banach said the findings from the experimental analyses are “very interesting and promising,” especially regarding the proinflammatory effects of anti–apo A-I antibodies.

However, he underlined that the clinical part, looking at antibody seropositivity in patients with NAFLD, was limited by the lack of a control group, and there was no indication as to what treatment the patients received, despite it being clear that many were obese.

Dr. Banach also believes that, taking into account the patient characteristics, it is likely that most of the patients had the more severe nonalcoholic steatohepatitis, and “it would be additionally useful to see the autoantibodies levels both in NASH and NAFLD.”

Nevertheless, the clinical utility of measuring anti–apo A-I antibodies is limited at this stage.

He said that the lack of “good, easy, and cheap diagnostic methods based on both laboratory and imaging data” for NAFLD means it would be difficult to determine whether assessing antibody seropositivity “might be indeed an added value.”
 

Independent predictors

Dr. Pagano explained that anti–apo A-I antibodies, which target the major protein fraction of HDL cholesterol, are independent predictors of cardiovascular events in high-risk populations.

They are also independently associated with cardiovascular disease in the general population, as well as atherosclerotic plaque vulnerability in both mice and humans.

She said that apo A-I antibodies have a metabolic role in vivo, and have been shown in vitro to disrupt cholesterol metabolism, promoting foam cell formation.

Studies have also indicated they play a role in hepatic fibrosis, predicting the development of cirrhosis in individuals with chronic hepatitis C infection.

The team therefore set out to determine the presence of anti–apo A-I antibodies in individuals with NAFLD, defined here as fatty acid levels greater than 5% of liver weight, as well as their effect on hepatic cells.

Working with colleagues at Magna Græcia University of Catanzaro (Italy), they obtained serum samples from 137 patients with NAFLD confirmed on ultrasound.

The patients had an average age of 49 years, and 48.9% were male. The median body mass index was 31.8 kg/m². Cholesterol levels were typically in the intermediate range.

They found that 46% of the participants had anti–apo A-I IgG antibodies, “which is quite high when compared with the 15%-20% positivity that we retrieved from the general population,” Dr. Pagano said.

To explore the link between high anti–apo A-I antibodies and NAFLD, the team studied hepatic cells, treating them with anti–apo A-I IgG antibodies or control IgG antibodies, or leaving them untreated, for 24 hours.

This revealed that anti–apo A-I IgG antibodies were associated with a significant increase in liquid droplet content in hepatic cells, compared with both cells treated with control IgG (P = .0008), and untreated cells (P = .0002).

Next, the team immunized apo E knockout mice with anti–apo A-I or control IgG antibodies. After 16 weeks, they found there was a significant increase in liver lipid content in mice given anti–apo A-I antibodies versus those treated with controls (P = .03).

They then asked whether anti–apo A-I antibodies could affect triglyceride metabolism. They examined the expression of the transcription factor sterol regulatory element binding protein (SREBP) and regulation of the triglyceride and cholesterol pathways.

Treating hepatic cells again for 24 hours with anti–apo A-I IgG antibodies or control IgG antibodies, or leaving them untreated, showed that anti–apo A-I antibodies were associated with “dramatic” increases in the active form of SREBP.

They also found that expression of two key enzymes in the triglyceride pathway, fatty acid synthetase and glycerol phosphate acyltransferase, was substantially decreased in the presence anti–apo A-I antibodies.

In both experiments, the untreated hepatic cells and those exposed to control IgG antibodies showed no significant changes.

“These results suggest that negative feedback ... turns off these enzymes, probably due to the lipid overload that is found in the cells after 24 hours of anti–apo A-I treatment,” Dr. Pagano said.

Finally, the researchers observed that anti–apo A-I, but not control antibodies, were associated with increases in inflammatory markers in liver cells.

Specifically, exposure to the antibodies was linked to an approximately 10-fold increase in interleukin-6 levels, as well as an approximate 25-fold increase in IL-8, and around a 7-fold increase in tumor necrosis factor–alpha.

Dr. Pagano suggested that the inflammatory effects are “probably mediated by binding anti–apo A-I antibodies to toll-like receptor 2, which has been previously described in macrophages.”

No funding was declared. The study authors disclosed no relevant financial relationships.

Specifically, exposure to the antibodies was linked to an approximately 10-fold increase in interleukin-6 levels, as well as an approximate 25-fold increase in IL-8, and around a 7-fold increase in tumor necrosis factor–alpha.

Dr. Pagano suggested that the inflammatory effects are “probably mediated by binding anti–apo A-I antibodies to toll-like receptor 2, which has been previously described in macrophages.”

Anti–apolipoprotein A-I (apo A-I) antibodies are common in nonalcoholic fatty liver disease and may not only drive its development but also underlie the link between NAFLD and cardiovascular disease, suggests a novel analysis.

Conducting a clinical analysis and a series of experiments, Sabrina Pagano, PhD, diagnostic department, Geneva University Hospital, and colleagues looked for anti–apo A-I antibodies in patients with NAFLD and then examined their impact on hepatic cells and inflammatory markers.

They found that nearly half of 137 patients with NAFLD were seropositive, and that the antibodies were associated with increased lipid accumulation in the liver, altered triglyceride metabolism, and proinflammatory effects on liver cells.

“We hypothesize that anti–apo A-I IgG may be a potential driver in the development of NAFLD, and further studies are needed to support anti–apo A-I IgG as a possible link between NAFLD and cardiovascular disease,” Dr. Pagano said.

The research was presented at the European Atherosclerosis Society 2021 Virtual Congress.

Asked whether anti–apo A-I antibodies could represent a potential treatment target for NAFLD, Dr. Pagano said in an interview that they have “already developed a peptide that is recognized by the antibodies in order to try to reverse the anti–apo A-I deleterious effect.”

While this was successful in vitro, “unfortunately we didn’t observe ... the peptide reverse of these anti–apo A-I effects in mice, so ... for the moment it’s a little early,” to say whether it represents a promising target.

Approached for comment, Maciej Banach, MD, PhD, full professor of cardiology, Polish Mother’s Memorial Hospital Research Institute, Lodz, said that the results are “very interesting and encouraging.”

He said that his own global burden of disease analysis, which is set to be published soon, showed that the worldwide prevalence of NAFLD is 11%, “representing almost 900 million cases,” and a more than 33% increase in prevalence in the past 30 years.

Consequently, any “attempt to have effective, especially early, diagnosis and treatment,” is highly anticipated.

Dr. Banach said the findings from the experimental analyses are “very interesting and promising,” especially regarding the proinflammatory effects of anti–apo A-I antibodies.

However, he underlined that the clinical part, looking at antibody seropositivity in patients with NAFLD, was limited by the lack of a control group, and there was no indication as to what treatment the patients received, despite it being clear that many were obese.

Dr. Banach also believes that, taking into account the patient characteristics, it is likely that most of the patients had the more severe nonalcoholic steatohepatitis, and “it would be additionally useful to see the autoantibodies levels both in NASH and NAFLD.”

Nevertheless, the clinical utility of measuring anti–apo A-I antibodies is limited at this stage.

He said that the lack of “good, easy, and cheap diagnostic methods based on both laboratory and imaging data” for NAFLD means it would be difficult to determine whether assessing antibody seropositivity “might be indeed an added value.”
 

Independent predictors

Dr. Pagano explained that anti–apo A-I antibodies, which target the major protein fraction of HDL cholesterol, are independent predictors of cardiovascular events in high-risk populations.

They are also independently associated with cardiovascular disease in the general population, as well as atherosclerotic plaque vulnerability in both mice and humans.

She said that apo A-I antibodies have a metabolic role in vivo, and have been shown in vitro to disrupt cholesterol metabolism, promoting foam cell formation.

Studies have also indicated they play a role in hepatic fibrosis, predicting the development of cirrhosis in individuals with chronic hepatitis C infection.

The team therefore set out to determine the presence of anti–apo A-I antibodies in individuals with NAFLD, defined here as fatty acid levels greater than 5% of liver weight, as well as their effect on hepatic cells.

Working with colleagues at Magna Græcia University of Catanzaro (Italy), they obtained serum samples from 137 patients with NAFLD confirmed on ultrasound.

The patients had an average age of 49 years, and 48.9% were male. The median body mass index was 31.8 kg/m². Cholesterol levels were typically in the intermediate range.

They found that 46% of the participants had anti–apo A-I IgG antibodies, “which is quite high when compared with the 15%-20% positivity that we retrieved from the general population,” Dr. Pagano said.

To explore the link between high anti–apo A-I antibodies and NAFLD, the team studied hepatic cells, treating them with anti–apo A-I IgG antibodies or control IgG antibodies, or leaving them untreated, for 24 hours.

This revealed that anti–apo A-I IgG antibodies were associated with a significant increase in liquid droplet content in hepatic cells, compared with both cells treated with control IgG (P = .0008), and untreated cells (P = .0002).

Next, the team immunized apo E knockout mice with anti–apo A-I or control IgG antibodies. After 16 weeks, they found there was a significant increase in liver lipid content in mice given anti–apo A-I antibodies versus those treated with controls (P = .03).

They then asked whether anti–apo A-I antibodies could affect triglyceride metabolism. They examined the expression of the transcription factor sterol regulatory element binding protein (SREBP) and regulation of the triglyceride and cholesterol pathways.

Treating hepatic cells again for 24 hours with anti–apo A-I IgG antibodies or control IgG antibodies, or leaving them untreated, showed that anti–apo A-I antibodies were associated with “dramatic” increases in the active form of SREBP.

They also found that expression of two key enzymes in the triglyceride pathway, fatty acid synthetase and glycerol phosphate acyltransferase, was substantially decreased in the presence anti–apo A-I antibodies.

In both experiments, the untreated hepatic cells and those exposed to control IgG antibodies showed no significant changes.

“These results suggest that negative feedback ... turns off these enzymes, probably due to the lipid overload that is found in the cells after 24 hours of anti–apo A-I treatment,” Dr. Pagano said.

Finally, the researchers observed that anti–apo A-I, but not control antibodies, were associated with increases in inflammatory markers in liver cells.

Specifically, exposure to the antibodies was linked to an approximately 10-fold increase in interleukin-6 levels, as well as an approximate 25-fold increase in IL-8, and around a 7-fold increase in tumor necrosis factor–alpha.

Although recent trial results have established the sodium glucose cotransporter 2 inhibitors dapagliflozin and empagliflozin as a key new part of the recommended multidrug treatment regimen for patients with heart failure with reduced ejection fraction, the current U.S. cost for dapagliflozin means it has merely “intermediate” value when it comes to cost-effectiveness.

A typical regimen with dapagliflozin to treat patients with heart failure with reduced ejection fraction (HFrEF) costs about $474/month or roughly $5,700/year based on Medicare pricing. After factoring in the incremental clinical benefits producing by dapagliflozin seen in the DAPA-HF pivotal trial that helped establish its role, this price produces a cost per quality-adjusted life-year (QALY) gain of about $84,000, which puts dapagliflozin squarely in the intermediate range for value set in 2014 by a task force of the American College of Cardiology and the American Heart Association.

This cost-effectiveness value depends largely on the proven efficacy of dapagliflozin (Farxiga) for decreasing the incidence of cardiovascular death among treated patients with HFrEF, and puts the drug’s value roughly on par with another agent recently approved to treat such patients, sacubitril/valsartan (Entresto), which carries a cost-effectiveness value of about $45,000/QALY.

The U.S. cost per QALY for dapagliflozin treatment of patients with HFrEF dwarfed the value numbers calculated for several other countries that were generally one-tenth this size. This disparity stemmed from both the relatively high price for dapagliflozin in the U.S. compared with other countries – nearly tenfold higher – and relatively higher costs for all types of U.S. medical care, Justin T. Parizo, MD, and coauthors said in a recent report. But the cost, and hence the cost per QALY, of dapagliflozin may soon drop because certain patents on the drug expired in October 2020, added Dr. Parizo, a cardiologist at Stanford (Calif.) University, and associates. Despite the expired patents, as of June 2021 no generic form of dapagliflozin appeared available for U.S. sale.
 

Medicare patients pay about $1,630/year out-of-pocket

“A key caveat” to this finding for dapagliflozin is that being cost-effective “is not by itself a mandate for routine clinical use,” Derek S. Chew, MD, and Daniel B. Mark, MD, said in an editorial that accompanied the report.

A major stumbling block for widespread U.S. prescribing of dapagliflozin to patients with HFrEF is its overall price tag for U.S. patients, estimated at $12 billion/year, as well as an out-of-pocket annual cost for individual Medicare patients of roughly $1,630/year. Adding this out-of-pocket cost to the copay for sacubitril/valsartan and two other much less expensive drug classes that together form the current mainstay, quadruple-drug regimen for HFrEF treatment means a potential annual cost paid by each Medicare patient of about $3,000, wrote Dr. Chew, a cardiologist, and Dr. Mark, a cardiologist and professor, both at Duke University, Durham, N.C.

They cited the precedent of the “unexpectedly slow” and “anemic” uptake of sacubitril/valsartan since its U.S. approval in 2015, a cost-effective agent with “comparable clinical effectiveness” to dapagliflozin. “Even with full inclusion [of sacubitril/valsartan] on formularies and elimination of preapproval requirements, use remains very low, and patient-borne out-of-pocket costs may be a key factor,” wrote Dr. Chew and Dr. Mark. They cited a results from a study that showed abandonment of new prescriptions at retail U.S. pharmacies spiked to a 60% rate when out-of-pocket cost exceeded $500.
 

More than what patients ‘can afford or are willing to spend’

The estimated $3,000-plus total out-of-pocket cost currently borne by some Medicare beneficiaries with HFrEF who have to shell out for both sacubitril/valsartan and dapagliflozin “appears to substantially exceed what many patients with heart failure can afford or are willing to spend,” wrote Dr. Chew and Dr. Mark.

Dr. Parizo and coauthors developed their cost-effectiveness model for dapagliflozin in treating HFrEF using primarily data collected in the DAPA-HF trial, which proved the efficacy of the drug for reducing cardiovascular deaths or acute heart failure events that led to hospitalization or intravenous outpatient treatment in more than 4,700 randomized patients with HFrEF. The trial enrolled roughly similar numbers of patients with or without type 2 diabetes.

The model showed an overall incremental cost-effectiveness ratio of $83,650/QALY, which was about the same regardless of whether patients also had type 2 diabetes. On a more granular level, the cost-effectiveness value estimate was $78,483/QALY in patients with mild health-status impairment due to their heart failure, and $97,608/QALY in patients with moderate impairment, a finding that underscores the importance of starting dapagliflozin treatment early in the course of HFrEF when disease effects are less severe. The analysis could not address value in patients with more advanced heart failure and in New York Heart Association functional class IV because fewer than 1% of patients in DAPA-HF were in this category.

Drug cost was a major determinant of cost-effectiveness. A 50% drop in cost from the Medicare benchmark of $473.64/month resulted in an incremental cost-effectiveness ratio of about $45,000/QALY (putting it into the high-value category based on the 2014 ACC/AHA formula), while a 50% rise in price yielded a value of nearly $123,000/QALY (still in the intermediate range, which spans from $50,000/QALY to $150,000/QALY). No other cost parameters had a meaningful effect on the cost-effectiveness calculation. The analyses also showed that using the basic cost assumptions, treatment with dapagliflozin needs to persist and remain effective for at least 44 months to produce a cost per QALY that’s less than $150,000. The authors stressed that their analysis considered heart failure effects and did not account for added benefit from treatment with dapagliflozin on preservation of renal function.

While it’s indisputable that treatment with dapagliflozin decreases health care costs by, for example, reducing hospitalizations for heart failure, each hospitalization costs just over $12,000, according to the assumptions made by Dr. Parizo and coauthors. But given dapagliflozin’s impact on this outcome, this cost saving translates into about $500/patient during 18 months on treatment (the median duration of treatment in DAPA-HF), which means the savings barely counterbalances the current cost of dapagliflozin treatment for 1 month, noted Dr. Chew and Dr. Mark.

The DAPA-HF trial was sponsored by AstraZeneca, the company that markets dapagliflozin (Farxiga). Dr. Parizo had no disclosures and none of his coauthors had a relationship with AstraZeneca. Dr. Chew had no disclosures. Dr. Mark has received research grants from HeartFlow, Mayo Clinic, and Merck.

People with prediabetes, defined by having a hemoglobin A1c of 5.7%-6.4%, had a significantly increased rate of atherosclerotic cardiovascular disease events and incident chronic kidney disease in a study of nearly 337,000 people included in the UK Biobank database.

The findings suggest that people with prediabetes have “heightened risk even without progression to type 2 diabetes,” Michael C. Honigberg, MD, said at the annual scientific sessions of the American College of Cardiology.

“Hemoglobin A1c may be better considered as a continuous measure of risk rather than dichotomized” as either less than 6.5%, or 6.5% or higher, the usual threshold defining people with type 2 diabetes, said Dr. Honigberg, a cardiologist at Massachusetts General Hospital in Boston.
 

‘Prediabetes is not a benign entity’

“Our findings reinforce the notion that A1c represents a continuum of risk, with elevated risks observed, especially for atherosclerotic cardiovascular disease [ASCVD], at levels where some clinicians wouldn’t think twice about them. Prediabetes is not a benign entity in the middle-aged population we studied,” Dr. Honigberg said in an interview. “Risks are higher in individuals with type 2 diabetes,” he stressed, “however, prediabetes is so much more common that it appears to confer similar cardio, renal, and metabolic risks at a population level.”

Results from prior observational studies also showed elevated incidence rate of cardiovascular disease events in people with prediabetes, including a 2010 report based on data from about 11,000 U.S. residents, and in a more recent meta-analysis of 129 studies involving more than 10 million people. The new report by Dr. Honigberg “is the first to comprehensively evaluate diverse cardio-renal-metabolic outcomes across a range of A1c levels using a very large, contemporary database,” he noted. In addition, most prior reports did not include chronic kidney disease as an examined outcome.

The primary endpoint examined in the new analysis was the combined incidence during a median follow-up of just over 11 years of ASCVD events (coronary artery disease, ischemic stroke, or peripheral artery disease), CKD, or heart failure among 336,709 adults in the UK Biobank who at baseline had none of these conditions nor type 1 diabetes.

The vast majority, 82%, were normoglycemic at baseline, based on having an A1c of less than 5.7%; 14% had prediabetes, with an A1c of 5.7%-6.4%; and 4% had type 2 diabetes based on an A1c of at least 6.5% or on insulin treatment. Patients averaged about 57 years of age, slightly more than half were women, and average body mass index was in the overweight category except for those with type 2 diabetes.

The primary endpoint, the combined incidence of ASCVD, CKD, and heart failure, was 24% among those with type 2 diabetes, 14% in those with prediabetes, and 8% in those who were normoglycemic at entry. Concurrently with the report, the results appeared online. Most of these events involved ASCVD, which occurred in 11% of those in the prediabetes subgroup (roughly four-fifths of the events in this subgroup), and in 17% of those with type 2 diabetes (nearly three-quarters of the events in this subgroup).

In an analysis that adjusted for more than a dozen demographic and clinical factors, the presence of prediabetes linked with significant increases in the incidence rate of all three outcomes compared with people who were normoglycemic at baseline. The analysis also identified an A1c level of 5.0% as linked with the lowest incidence of each of the three adverse outcomes. And a very granular analysis suggested that a significantly elevated risk for ASCVD first appeared when A1c levels were in the range of 5.4%-5.7%; a significantly increased incidence of CKD became apparent once A1c was in the range of 6.2%-6.5%; and a significantly increased incidence of heart failure began to manifest once A1c levels reached at least 7.0%.

Need for comprehensive cardiometabolic risk management

The findings “highlight the importance of identifying and comprehensively managing cardiometabolic risk in people with prediabetes, including dietary modification, exercise, weight loss and obesity management, smoking cessation, and attention to hypertension and hypercholesterolemia,” Dr. Honigberg said. While these data cannot address the appropriateness of using novel drug interventions in people with prediabetes, they suggest that people with prediabetes should be the focus of future prevention trials testing agents such as sodium-glucose cotransporter 2 inhibitors.

“These data help us discuss risk with patients [with prediabetes], and reemphasize the importance of guideline-directed preventive care,” said Vijay Nambi, MD, PhD, a preventive cardiologist and lipid specialist at Baylor College of Medicine and the Michael E.

An additional analysis reported by Dr. Honigberg examined the risk among people with prediabetes who also were current or former smokers and in the top tertile of the prediabetes study population for systolic blood pressure, high non-HDL cholesterol, and C-reactive protein (a marker of inflammation). This very high-risk subgroup of people with prediabetes had incidence rates for ASCVD events and for heart failure that tracked identically to those with type 2 diabetes. However. the incidence rate for CKD in these high-risk people with prediabetes remained below that of patients with type 2 diabetes.

People with prediabetes, defined by having a hemoglobin A1c of 5.7%-6.4%, had a significantly increased rate of atherosclerotic cardiovascular disease events and incident chronic kidney disease in a study of nearly 337,000 people included in the UK Biobank database.

The findings suggest that people with prediabetes have “heightened risk even without progression to type 2 diabetes,” Michael C. Honigberg, MD, said at the annual scientific sessions of the American College of Cardiology.

“Hemoglobin A1c may be better considered as a continuous measure of risk rather than dichotomized” as either less than 6.5%, or 6.5% or higher, the usual threshold defining people with type 2 diabetes, said Dr. Honigberg, a cardiologist at Massachusetts General Hospital in Boston.
 

‘Prediabetes is not a benign entity’

“Our findings reinforce the notion that A1c represents a continuum of risk, with elevated risks observed, especially for atherosclerotic cardiovascular disease [ASCVD], at levels where some clinicians wouldn’t think twice about them. Prediabetes is not a benign entity in the middle-aged population we studied,” Dr. Honigberg said in an interview. “Risks are higher in individuals with type 2 diabetes,” he stressed, “however, prediabetes is so much more common that it appears to confer similar cardio, renal, and metabolic risks at a population level.”

Results from prior observational studies also showed elevated incidence rate of cardiovascular disease events in people with prediabetes, including a 2010 report based on data from about 11,000 U.S. residents, and in a more recent meta-analysis of 129 studies involving more than 10 million people. The new report by Dr. Honigberg “is the first to comprehensively evaluate diverse cardio-renal-metabolic outcomes across a range of A1c levels using a very large, contemporary database,” he noted. In addition, most prior reports did not include chronic kidney disease as an examined outcome.

The primary endpoint examined in the new analysis was the combined incidence during a median follow-up of just over 11 years of ASCVD events (coronary artery disease, ischemic stroke, or peripheral artery disease), CKD, or heart failure among 336,709 adults in the UK Biobank who at baseline had none of these conditions nor type 1 diabetes.

The vast majority, 82%, were normoglycemic at baseline, based on having an A1c of less than 5.7%; 14% had prediabetes, with an A1c of 5.7%-6.4%; and 4% had type 2 diabetes based on an A1c of at least 6.5% or on insulin treatment. Patients averaged about 57 years of age, slightly more than half were women, and average body mass index was in the overweight category except for those with type 2 diabetes.

The primary endpoint, the combined incidence of ASCVD, CKD, and heart failure, was 24% among those with type 2 diabetes, 14% in those with prediabetes, and 8% in those who were normoglycemic at entry. Concurrently with the report, the results appeared online. Most of these events involved ASCVD, which occurred in 11% of those in the prediabetes subgroup (roughly four-fifths of the events in this subgroup), and in 17% of those with type 2 diabetes (nearly three-quarters of the events in this subgroup).

In an analysis that adjusted for more than a dozen demographic and clinical factors, the presence of prediabetes linked with significant increases in the incidence rate of all three outcomes compared with people who were normoglycemic at baseline. The analysis also identified an A1c level of 5.0% as linked with the lowest incidence of each of the three adverse outcomes. And a very granular analysis suggested that a significantly elevated risk for ASCVD first appeared when A1c levels were in the range of 5.4%-5.7%; a significantly increased incidence of CKD became apparent once A1c was in the range of 6.2%-6.5%; and a significantly increased incidence of heart failure began to manifest once A1c levels reached at least 7.0%.

Need for comprehensive cardiometabolic risk management

The findings “highlight the importance of identifying and comprehensively managing cardiometabolic risk in people with prediabetes, including dietary modification, exercise, weight loss and obesity management, smoking cessation, and attention to hypertension and hypercholesterolemia,” Dr. Honigberg said. While these data cannot address the appropriateness of using novel drug interventions in people with prediabetes, they suggest that people with prediabetes should be the focus of future prevention trials testing agents such as sodium-glucose cotransporter 2 inhibitors.

“These data help us discuss risk with patients [with prediabetes], and reemphasize the importance of guideline-directed preventive care,” said Vijay Nambi, MD, PhD, a preventive cardiologist and lipid specialist at Baylor College of Medicine and the Michael E. DeBakey VA Medical Center in Houston, who was not involved with the study.

Myocarditis is present in a small percentage of competitive athletes after COVID-19 infection, even in those without symptoms, new research suggests.

In a cohort study of 1,597 competitive collegiate athletes undergoing comprehensive cardiovascular testing in the United States, the prevalence of clinical myocarditis based on a symptom-based screening strategy was only 0.31%.

But screening with cardiac MRI increased the prevalence of clinical and subclinical myocarditis by a factor of 7.4, to 2.3%, the authors reported.

The findings are published online May 27, 2021, in JAMA Cardiology.

“It was the largest study to evaluate college athletes who have had COVID with extensive cardiac testing, including MRI, and this gave us a very objective look at the cardiac findings, as they were not purely based upon a subjective evaluation of symptoms,” lead investigator Curt J. Daniels, MD, professor at Ohio State University Wexner Medical Center, Columbus, said in an interview.

“Unfortunately, our study showed that athletes can be asymptomatic, or at least not report symptoms. This is a very subjective feature, and we don’t know if they don’t report symptoms because they didn’t want to get tested. That is why we took a very objective approach,” Dr. Daniels said.

The finding that more than half of the asymptomatic athletes had myocarditis, or as the investigators called it, “subclinical myocarditis,” was a surprise, he acknowledged.

“More than half of the athletes found to have myocarditis reported no symptoms, and yes, that was a surprise, because prior to this study, the protocols that had been published stated that you had to have symptoms to even enter into the protocol for cardiac MRI. But, as our ... paper shows, if we had followed that protocol, we only would have found about 5 cases of myocarditis, as opposed to the total of 37 we found with cardiac MRI,” Dr. Daniels said.

In October 2020, the American College of Cardiology’s Sports and Exercise Council recommended that cardiac MRI be limited to athletes who exhibited symptoms as part of their guide to ensuring a safe return to play.

As reported by this news organization the council recommended a tiered approach to screening based on the presence of symptoms, followed by electrocardiography, injury biomarkers, and echocardiography. Any abnormalities detected were to be further characterized by the selective use of cardiac MRI.

At the time, there were relatively few data to support the recommendations, and all stakeholders called for larger datasets to better drive informed recommendations in the future.

In the current study, Dr. Daniels and associates conducted comprehensive cardiac screening – including ECG, troponin testing, echocardiography, and cardiac MRI – of 1,597 college athlete survivors of COVID-19.

The athletes were part of the Big Ten athletic conference, which consists of 13 major American universities.

Cardiac MRI revealed that 37 (2.3%) of these athletes demonstrated diagnostic criteria for COVID-19 myocarditis; of these, 20 had no cardiovascular symptoms and had normal ECGs, echocardiography, and troponin test results.

“These patients would not have been identified without CMR imaging. If we were going according to the older protocol, we would not have made this discovery. Cardiac MRI is the most sensitive and specific test for myocardial inflammation, there is no argument about that,” Dr. Daniels said.

The catch is, cardiac MRI is expensive and often difficult to access, especially in remote, rural, or other underserviced areas.

“You can’t get an MRI for every person who has had COVID, it’s just not feasible,” Dr. Daniels said. “We are not advocating that everybody get an MRI. But we do hope that our study creates awareness among clinicians and athletes themselves that if you’ve had COVID, even if you’re asymptomatic, there may be some heart changes. So be aware when you start to exercise again, if you have any symptoms, pause and seek medical care.”
 

Kudos to the sports cardiology community

In an accompanying editorial, James E. Udelson, MD, Ethan J. Rowin, MD, and Barry J. Maron, MD, from the CardioVascular Center at Tufts Medical Center, Boston, applauded the sports cardiology community for its diligence in acquiring and publishing data about the post–COVID-19 prevalence of cardiac abnormalities in competitive athletes.

“It is a real tribute to the sports cardiology community. There has been an amazing growth of information, and they not only gathered this information, they analyzed and published it, starting out with a study of 29 or 30 athletes, and now thousands,” Dr. Udelson said in an interview.

At the start of the pandemic, it appeared that 15%-20% of athletes had myocarditis, and athletic conferences were discussing canceling sports events.

However, with greater numbers comes a more accurate picture of the extent of the problem.

“Once you get thousands of subjects in these studies, you can hone in on what the real number is, so now we understand that if you screen everybody with a cardiac MRI, 1%, 2%, or 3% will have some evidence of what looks like myocarditis,” he said.

Dr. Udelson agreed that doing cardiac imaging in everyone is not feasible.

“This study looked at a very large number of people who all had an MRI, but that doesn’t mean everyone should have them. If you just do an echo, an EKG, and a troponin test, and if everything is normal, which is kind of what current recommendations are, this paper tells us that we are going to miss one or two people out of a hundred, and that might be okay,” he said. “So, if you are at a huge university that has a large medical center and you want to screen all your athletes with MRI, great. But if you’re at a high school in a remote area, you know that the alternative, not having an MRI, isn’t so bad, either.”

Pericardial fat is associated with a heightened risk for heart failure, particularly in women, new research suggests.

In a prospective cohort study of nearly 7,000 individuals, excess pericardial fat was linked to a higher risk for heart failure, even after adjustment for established risk factors for heart failure.

Women with high pericardial fat volume (PFV), defined as more than 70 cm³ or 2.4 fluid ounces, had double the risk of developing heart failure. For men, high PFV, defined as more than 120 cm³ or 4.0 fluid ounces, was associated with a 50% increase in the risk for heart failure.

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

“People will ask why should they measure fat around the heart. Why can’t they just take the waist circumference or body mass index as a measure for increased risk?” lead author Satish Kenchaiah, MD, MPH, Icahn School of Medicine at Mount Sinai, New York, said in an interview.

“Yet, when we adjusted for waist circumference, hip circumference, waist to hip ratio, and other known variables, pericardial fat was still associated with an increased risk of heart failure. This tells me that it is not just overall fat in the body but something about its location around the heart that is playing a role,” Dr. Kenchaiah said.

“Now that we have found an association between any amount of fat around the pericardium and heart failure, it gives us an impetus to build future research on identifying how exactly these fat deposits influence the development of cardiomyopathy,” he said.

Dr. Kenchaiah and colleagues investigated the association of pericardial fat with incident heart failure by examining chest CT scans from 6,785 participants (3,584 women and 3,201 men aged 45-84 years) in the Multi-Ethnic Study of Atherosclerosis.

The participants were from four different ethnic groups: 38% were White; 28% were Black, 22% were Hispanic, and 12% were Chinese American. They were recruited between July 17, 2000, and Aug. 31, 2002, from six communities in the United States: Baltimore and Baltimore County; Chicago; Forsyth County, N.C.; Los Angeles County northern Manhattan and the Bronx, New York; and St. Paul, Minn.

All participants were free of cardiovascular disease at baseline.

The researchers followed participants for more than 17 years. During this time, 385 (5.7%; 164 women and 221 men) developed newly diagnosed heart failure.

In women, the hazard ratio for every 42 cm³ increase in PFV was 1.44 (95% confidence interval, 1.21-1.71; P < .001). In men, the HR was 1.13 (95% CI, 1.01-1.27; P = .03).

High PVF conferred a twofold greater risk for heart failure in women (HR, 2.06; 95% CI, 1.48-2.87; P < .001) and a 53% higher risk in men (HR, 1.53; 95% CI, 1.13-2.07; P = .006).

These associations remained significant after further adjustment for circulating markers of systemic inflammation (that is, C-reactive protein and interleukin-6), and abdominal subcutaneous or visceral fat.

They also found that the heightened risk persisted, even after adjustment for established risk factors for heart failure, such as age, cigarette smoking, alcohol consumption, sedentary lifestyle, high blood pressure, high blood sugar, high cholesterol, and myocardial infarction.

Results were similar among all of the ethnic groups studied.
 

A surprise finding

“The most surprising part of this study was that the risk for heart failure with increased pericardial fat does not seem to be explained by obesity and systemic inflammation alone,” Andreas P. Kalogeropoulos, MD, MPH, PhD, Stony Brook (N.Y.) University, said in an interview.

“If pericardial fat was merely a proxy for increased visceral fat, one would expect the association of pericardial fat with heart failure risk to go away after factoring in abdominal CT findings, which was not the case here. Also, accounting for inflammatory markers did not change things dramatically. However, we need to be careful here, as abdominal CT scans have not been done simultaneously with the pericardial fat scans in the study,” said Dr. Kalogeropoulos, who coauthored an accompanying editorial with Michael E. Hall, MD, University of Mississippi Medical Center, Jackson.

The other striking finding, although not entirely surprising, was the stronger association of pericardial fat with heart failure risk in women, he noted.

“Although several clues have been reported pointing to women being more sensitive to the adverse cardiac effects of pericardial fat, this is the first large prospective study to connect the dots and show much higher risk in women in a convincing way. For the record, this is the first prospective study to show the connection between pericardial fat and heart failure risk altogether,” Dr. Kalogeropoulos said.

“Obviously, we need to do more work to see how we can use the important findings of Kenchaiah and colleagues to reduce risk for heart failure among patients with increased pericardial fat, especially women. For starters, we would need a way to identify these patients,” he said. “In this aspect, it is encouraging that pericardial fat can be measured in low-radiation CT scans, similar to those used for coronary calcium, and that automation technology to speed up pericardial fat measurements is already in the pipeline.

“The next step would be to see what kind of interventions would reduce risk for heart failure in these patients,” he added. “Weight loss would be an obvious thing, but novel agents with favorable cardiometabolic effects, like newer antidiabetic medications, are intriguing options, too.”

The study was supported by the National Heart, Lung, and Blood Institute and the National Institutes of Health. Dr. Kenchaiah and Dr. Kalogeropoulos reported no relevant financial relationships.

Pericardial fat is associated with a heightened risk for heart failure, particularly in women, new research suggests.

In a prospective cohort study of nearly 7,000 individuals, excess pericardial fat was linked to a higher risk for heart failure, even after adjustment for established risk factors for heart failure.

Women with high pericardial fat volume (PFV), defined as more than 70 cm³ or 2.4 fluid ounces, had double the risk of developing heart failure. For men, high PFV, defined as more than 120 cm³ or 4.0 fluid ounces, was associated with a 50% increase in the risk for heart failure.

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

“People will ask why should they measure fat around the heart. Why can’t they just take the waist circumference or body mass index as a measure for increased risk?” lead author Satish Kenchaiah, MD, MPH, Icahn School of Medicine at Mount Sinai, New York, said in an interview.

“Yet, when we adjusted for waist circumference, hip circumference, waist to hip ratio, and other known variables, pericardial fat was still associated with an increased risk of heart failure. This tells me that it is not just overall fat in the body but something about its location around the heart that is playing a role,” Dr. Kenchaiah said.

“Now that we have found an association between any amount of fat around the pericardium and heart failure, it gives us an impetus to build future research on identifying how exactly these fat deposits influence the development of cardiomyopathy,” he said.

Dr. Kenchaiah and colleagues investigated the association of pericardial fat with incident heart failure by examining chest CT scans from 6,785 participants (3,584 women and 3,201 men aged 45-84 years) in the Multi-Ethnic Study of Atherosclerosis.

The participants were from four different ethnic groups: 38% were White; 28% were Black, 22% were Hispanic, and 12% were Chinese American. They were recruited between July 17, 2000, and Aug. 31, 2002, from six communities in the United States: Baltimore and Baltimore County; Chicago; Forsyth County, N.C.; Los Angeles County northern Manhattan and the Bronx, New York; and St. Paul, Minn.

All participants were free of cardiovascular disease at baseline.

The researchers followed participants for more than 17 years. During this time, 385 (5.7%; 164 women and 221 men) developed newly diagnosed heart failure.

In women, the hazard ratio for every 42 cm³ increase in PFV was 1.44 (95% confidence interval, 1.21-1.71; P < .001). In men, the HR was 1.13 (95% CI, 1.01-1.27; P = .03).

High PVF conferred a twofold greater risk for heart failure in women (HR, 2.06; 95% CI, 1.48-2.87; P < .001) and a 53% higher risk in men (HR, 1.53; 95% CI, 1.13-2.07; P = .006).

These associations remained significant after further adjustment for circulating markers of systemic inflammation (that is, C-reactive protein and interleukin-6), and abdominal subcutaneous or visceral fat.

They also found that the heightened risk persisted, even after adjustment for established risk factors for heart failure, such as age, cigarette smoking, alcohol consumption, sedentary lifestyle, high blood pressure, high blood sugar, high cholesterol, and myocardial infarction.

Results were similar among all of the ethnic groups studied.
 

A surprise finding

“The most surprising part of this study was that the risk for heart failure with increased pericardial fat does not seem to be explained by obesity and systemic inflammation alone,” Andreas P. Kalogeropoulos, MD, MPH, PhD, Stony Brook (N.Y.) University, said in an interview.

“If pericardial fat was merely a proxy for increased visceral fat, one would expect the association of pericardial fat with heart failure risk to go away after factoring in abdominal CT findings, which was not the case here. Also, accounting for inflammatory markers did not change things dramatically. However, we need to be careful here, as abdominal CT scans have not been done simultaneously with the pericardial fat scans in the study,” said Dr. Kalogeropoulos, who coauthored an accompanying editorial with Michael E. Hall, MD, University of Mississippi Medical Center, Jackson.

The other striking finding, although not entirely surprising, was the stronger association of pericardial fat with heart failure risk in women, he noted.

“Although several clues have been reported pointing to women being more sensitive to the adverse cardiac effects of pericardial fat, this is the first large prospective study to connect the dots and show much higher risk in women in a convincing way. For the record, this is the first prospective study to show the connection between pericardial fat and heart failure risk altogether,” Dr. Kalogeropoulos said.

“Obviously, we need to do more work to see how we can use the important findings of Kenchaiah and colleagues to reduce risk for heart failure among patients with increased pericardial fat, especially women. For starters, we would need a way to identify these patients,” he said. “In this aspect, it is encouraging that pericardial fat can be measured in low-radiation CT scans, similar to those used for coronary calcium, and that automation technology to speed up pericardial fat measurements is already in the pipeline.

The U.S. Department of Justice (DOJ) on May 26 announced charges against 14 defendants across the country who allegedly engaged in health care fraud schemes that exploited the COVID-19 pandemic and resulted in over $143 million in false billings to Medicare.

Among the defendants, a DOJ news release said, were a telemedicine company executive, a physician, marketers, and medical business owners.

In addition, the Centers for Medicare and Medicaid Services separately announced that it had taken “adverse administrative actions” against more than 50 providers for their involvement in fraud schemes related to COVID-19 or the abuse of CMS programs that were designed to encourage access to medical care during the pandemic.

Several of the defendants allegedly offered COVID-19 tests to Medicare beneficiaries in senior living facilities, drive-through COVID-19 testing sites, and medical offices to induce the beneficiaries to provide their personal identifying information and a saliva or a blood sample.

The DOJ charges claim the defendants then misused the information and the samples to submit claims to Medicare for unrelated, medically unnecessary, and far more expensive lab tests, including cancer genetic testing, allergy testing, and respiratory pathogen panel tests.

In some cases, it’s alleged, the lab results were not provided to the individuals in a timely fashion or were not reliable.

Other defendants are charged with exploiting temporary changes in CMS telehealth regulations that were designed to increase access to health care during the pandemic. In these cases, which the DOJ said were the first charges related to the expansion of telehealth under the COVID-19 emergency declaration, the defendants allegedly submitted false and fraudulent claims to Medicare for sham telemedicine encounters that did not occur.

“As part of these cases, medical professionals are alleged to have [been] offered and paid bribes in exchange for the medical professionals’ referral of unnecessary testing,” the DOJ news release said. However, no physicians were identified by the department.

Commenting on this aspect of the law enforcement action, FBI Director Christopher Wray said in the release: “Medical providers have been the unsung heroes for the American public throughout the pandemic. It’s disheartening that some have abused their authorities and committed COVID-19–related fraud against trusting citizens. The FBI, along with our federal law enforcement and private sector partners, are committed to continuing to combat health care fraud and protect the American people.”

The law enforcement action includes the third set of criminal charges related to the misuse of Provider Relief Fund monies, according to the release.

More than 340 individuals were charged in September 2020 with submitting $6 billion in fraudulent claims to federal health care programs and private insurers for telehealth consultations and substance abuse treatment. About $4.5 billion of that was related to telehealth, as reported by this news organization.

The new criminal charges were brought in federal district courts in Arkansas, California, Louisiana, Florida, New Jersey, and New York.
 

Case summaries

The DOJ provided several case summaries. One defendant, lab owner Billy Joe Taylor of Lavaca, Ark., was charged with participating in a scheme to defraud the government of over $42 million by filing false claims that were billed in combination with COVID-19 testing claims. He also allegedly billed for tests that were not performed.

Petros Hannesyan of Burbank, Calif., the owner of a home health agency, was charged with obtaining over $229,000 from COVID-19 relief programs under false pretenses. His firm allegedly misappropriated funds from the CARES Act Provider Relief Fund and submitted false loan applications and a false loan agreement to the Economic Injury Disaster Loan Program.

Michael Stein and Leonel Palatnik of Palm Beach County, Fla., were charged in a connection with an alleged $73 million conspiracy to defraud the government and to pay and receive health care kickbacks during the pandemic.

Mr. Stein, who owned a “purported” consulting company, and Mr. Palatnik, who owned testing labs in Texas, allegedly exploited Medicare’s waiver of telehealth restrictions “by offering telehealth providers access to Medicare beneficiaries for whom they could bill consultations. In exchange, these providers agreed to refer beneficiaries to [Mr. Palatnik’s] laboratories for expensive and medically unnecessary cancer and cardiovascular genetic testing.”
