Post–COVID-19 cardiac involvement in college athletes much rarer than thought
In a multicenter study conducted during September-December 2020, only 0.7% of 3,018 collegiate athletes who tested positive for SARS-CoV-2 infection were found to have definite, probable, or possible infection-related cardiac involvement.
None experienced an adverse cardiac event and only five (0.2%) required hospitalization for noncardiac complications of COVID-19.
“The take-home message is that cardiac involvement does not happen as much as we had initially feared. It’s in the range of 0.5% to 3%, depending on how you define cardiac involvement, which is not nothing, but it’s not the 30% or 50% that some early studies hinted at,” said Kimberly G. Harmon, MD, of the University of Washington, Seattle.
Dr. Harmon, along with Jeffrey A. Drezner, MD, also from UW, and Aaron L. Baggish, MD, of Massachusetts General Hospital, Boston, were co–primary investigators of the Outcomes Registry for Cardiac Conditions in Athletes (ORCCA) study. The group’s findings were published April 17 in Circulation.
Nearly 20,000 athletes tested
The researchers prospectively tested 19,378 athletes for SARS-CoV-2 infection from 42 U.S. colleges and universities during the study period. A total of 3,018 (16%; mean age, 20 years; 32% female) tested positive and underwent cardiac evaluation.
“We didn’t prescribe what the schools had to do in terms of cardiac evaluation, but most of these colleges are well resourced, and about 74% of athletes were evaluated using the triad testing strategy of 12-lead electrocardiography, cardiac troponin, and transthoracic echocardiography [TEE], with cardiac magnetic resonance [CMR ]when indicated,” explained Dr. Harmon. Only 198 athletes underwent primary screening with CMR.
Athletes were often tested multiple times for SARS-CoV-2 infection by participating institutions and were included in this study if they had any positive test and underwent postinfection cardiac screening.
The cohort includes athletes representing 26 distinct sporting disciplines, including American-style football (36%), basketball (9%), and cross country/track and field (8%). Most were asymptomatic or had only mild COVID-19 symptoms (33% and 29%, respectively).
‘Exercise appears to be protective’
Abnormal findings suggestive of SARS-CoV-2 cardiac involvement were detected by ECG in 0.7% of athletes (21 of 2,999), cardiac troponin elevation in 0.9% (24/2,719), and abnormal TTE findings in 0.9% (24/2,556).
The odds of having cardiac involvement was 3.1 times higher in athletes with cardiopulmonary symptoms.
“One thing we’ve seen in the literature and in this cohort, is that exercise appears to be protective to some extent from COVID-19. We had a lot of cases, but in the whole cohort, only five athletes were hospitalized with COVID and those were for noncardiac reasons,” said Dr. Harmon.
During a median clinical surveillance of 113 days, there was one (0.03%) adverse cardiac event likely unrelated to SARS-CoV-2 infection.
The diagnostic yield for probable or definite cardiac involvement was 6.7 times higher for a CMR obtained for clinical reasons (10.1%) versus a primary screening CMR (1.5%).
“This is data we desperately needed. Small, single-center studies early in the pandemic had indicated a higher prevalence of cardiac involvement, which led us to be very conservative about return-to-play in the early days,” said Jeffrey Lander, MD, who was not involved in the study.
The study is complementary, he noted, to one published in March that looked at professional athletes post–COVID-19 and also found cardiac pathology in fewer than 1%. The mean age in that study was 25 years.
“They saw a similarly low rate of cardiac involvement in professional athletes, and together with this study, it gives us new information that is also reassuring,” added Dr. Lander, codirector of sports cardiology at Saint Barnabas Medical Center in Livingston, N.J., an RWJBarnabas Health facility, and team cardiologist for Seton Hall University in South Orange, N.J.
Limit CMR to symptomatic athletes
“I think this data can be extended beyond the college athlete. And it’s fair to say to high school athletes and young recreational athletes who have had asymptomatic or mild infection, you probably don’t need further workup if you’re feeling fine,” suggested Dr. Harmon.
“For those with moderate or severe illness, then the triple screen protocol is a good idea, particularly if they are having any symptoms,” she added.
Dr. Lander agrees that athletes should be screened by appropriate providers before returning to sports, but that CMR should not be used routinely for return-to-play screening.
“We’ve never taken a group of, say, 1,000 college athletes who just recovered from the flu and done cardiac MRIs on them, so it’s a bit like opening Pandora’s box when it’s used too liberally. It’s difficult to assess if the findings are secondary to COVID infection or from something entirely unrelated,” he noted.

AHA statement on obesity emphasizes abdominal fat, AFib
An updated American Heart Association scientific statement on the role of obesity in cardiovascular disease provides the first new guidance in 15 years, drawing on evidence that’s emerged in that time to clarify the potential of newer drug therapies and interventions like bariatric surgery and lifestyle modifications to curtail cardiovascular disease risks.
“The timing of this information is important because the obesity epidemic contributes significantly to the global burden of cardiovascular disease and numerous chronic health conditions that also impact heart disease,” said Tiffany Powell-Wiley, MD, MPH, chair of the volunteer statement writing group.
“One of the big takeaways that I hope people get from the statement is really making it clear that obesity is a complex disease, and that it is multifactorial,” Dr. Powell-Wiley said in an interview. “There are not just biological reasons why individuals have obesity, but there are environmental, psychosocial, and really multilevel factors that contribute to the development and course of obesity.”
Most significantly, Dr. Powell-Wiley said, “we want to emphasize that we really want to have cardiologists think about and focus on abdominal obesity in particular.”
A metric for cardiovascular risk that seems to gain credibility in the statement is the relationship of waist circumference to height regardless of overall weight. “That is a very important finding that we can now really think of waist circumference as an important measure in our clinical practice,” said Dr. Powell-Wiley, chief of the Social Determinants of Obesity and Cardiovascular Risk Laboratory in the division of intramural research at the National Heart, Lung, and Blood Institute. “We want to get across to providers that this is something that should be measured and should be followed over time, based on data from the last 15 years that waist circumference and abdominal obesity are associated with higher cardiovascular risk regardless of body mass index.”
The statement provides potentially groundbreaking advice on atrial fibrillation as a consequence of weight, noted Dr. Powell-Wiley. “Up until recently, we haven’t really thought about weight management as a part of managing Afib [atrial fibrillation],” she said. “This statement highlights the need to think about weight management in addition to anticoagulation as part of the pieces for managing Afib.”
Evidence on interventions
The statement, published in Circulation, also dives into the evidence surrounding the varied interventions for managing weight.
“The biggest area where there’s much more data is bariatric surgery,” said Dr. Powell-Wiley. “There’s clear evidence that bariatric surgery lowers cardio mortality and all-cause mortality for patients, but we’ve also seen data around lifestyle interventions, with the Look AHEAD trial, which showed that while there were improvements in CV [cardiovascular] risk factors, we didn’t see the reduction in CV mortality that we wanted to see.”
The statement noted that the Look AHEAD trial (for Action for Health in Diabetes) of people with type 2 diabetes failed to show a significant reduction in major adverse cardiac events or CV mortality after almost 10 years of an intensive weight-loss intervention. Dr. Powell-Wiley added that the result seemed to be related more to the lack of weight loss with lifestyle interventions when compared with bariatric surgery.
The statement also addressed the effectiveness of drug treatments for weight control in managing CV risk, and while the evidence supporting pharmacotherapy specifically for weight loss has been mixed, emerging treatments have shown promise, Dr. Powell-Wiley said. “I think we now have some bright spots with new therapies that have been developed for diabetes and heart failure, such as the SGLT2 inhibitors as well as the GLP-1 agonists, and how they can also appear to improve weight and likely will improve CV mortality in patients with obesity.”
The “obesity paradox,” which Dr. Powell-Wiley noted is “definitely a controversial topic,” is also addressed in the statement. “We try to explain what it is and what we know about it right now,” she said. “We know for instance that patients with obesity, particularly those who have class 1 obesity or patients who are overweight, seem to do better in the short term in relation to coronary artery disease and heart failure, but the reasons for that are not necessarily clear.”
The statement also provides evidence-based insights on the use of diagnostic tools, including stress echocardiography and cardiac MRI as well as coronary angiography, and the clinical significance of specific echocardiographic changes in obese patients.
The writing committee also identified areas that need future research. “It’s really important to emphasize what we learned about the complexity of obesity over this time period,” Dr. Powell-Wiley said. “But again, we don’t have all the answers; there’s a lot more work to be done to understand what type of lifestyle intervention might be most beneficial, especially with addressing abdominal obesity, and how these new therapeutics around heart failure and diabetes may be useful in patients with obesity.
Obesity in adolescents is another area that needs further research, Dr. Powell-Wiley said. “How do we prevent obesity in those populations when we know they’re at risk for so much as they get older? Once you have obesity it’s hard to change that trajectory.”
The scientific statement was prepared by the volunteer writing group on behalf of the AHA’s Council on Lifestyle and Cardiometabolic Health, the Council on Cardiovascular and Stroke Nursing, the Council on Clinical Cardiology, the Council on Epidemiology and Prevention, and the Stroke Council. Committee vice chair Paul Poirier, MD, PhD, reported financial relationships with Abbott, Amgen, AstraZeneca, Bausch Health, Bayer, Boehringer Ingelheim, Eli Lilly, Janssen, Novartis, Novo Nordisk, Sanofi, Servier, and HLS Therapeutics. One committee member disclosed a financial relationship with AstraZeneca. Dr. Powell-Wiley and the other committee members have no relationships to disclose.

Severe obesity persists, takes high cardiovascular toll
In a U.K. cohort of more than 260,000 mostly middle-aged adults in primary care with overweight or obesity, body mass index remained relatively stable over a decade.
However, compared to overweight individuals, those with severe (class 3) obesity were more socioeconomically disadvantaged and had triple the risk for incident heart failure or all-cause or cardiovascular disease (CVD)–related mortality in a study published online April 15 in BMC Public Health.
“This is the first study to evaluate the long-term impact of overweight and obese individuals’ BMI trajectory on cardiovascular endpoints, heart failure, and mortality outcomes,” wrote Barbara Iyen, PhD, University of Nottingham, England, and colleagues.
The findings emphasize “the high cardiovascular toll exacted by continuing failure to tackle obesity, particularly among more socioeconomically deprived populations,” they warned.
“We have found that despite widespread efforts to prevent and manage obesity, the majority of adults who are overweight or obese in the general population continue to remain so in the long term,” Dr. Iyen said in a statement from her university.
“More effective policies and weight-management interventions are needed urgently to address this increasing burden and associated adverse health outcomes,” she stressed.
Invited to comment, Sadiya S. Khan, MD, Northwestern University, Chicago, said in an interview: “This research adds to the growing body of evidence [that] earlier and more intensive interventions for weight loss are necessary to promote cardiovascular health and reduce morbidity and mortality.
“Adjunctive pharmacotherapy and bariatric surgery are both options that should be considered in addition to intensive lifestyle interventions in overweight and obesity groups,” she added.
“I would always advocate for earlier prevention efforts focused on weight loss, because years lived with obesity are associated with future CVD, so every year counts,” Dr. Khan said.
Does BMI remain elevated, predict worse heart health?
Although obesity is a well-recognized risk factor for CVD, long-term changes in BMI and the impact of BMI on the risk for heart failure, CVD, and mortality have not been quantified among adults with overweight and obesity, Dr. Iyen and colleagues explained.
The researchers examined data from the UK Clinical Practice Research Datalink and secondary care and mortality records to determine BMI trajectories among adults with overweight or obesity and to quantify the risk for heart failure, CVD (defined as coronary heart disease, stroke, transient ischemic attack, or peripheral vascular disease, CVD-related mortality, and all-cause mortality.
They identified 264,230 adults with overweight or obesity who were seen in 790 primary care practices in the United Kingdom from 1999 to 2018 and who did not initially have heart failure or CVD and for whom baseline BMI measurements and at least one other BMI measurement 2, 5, 8, and 10 years later was available.
The researchers divided the cohort into four groups on the basis of initial BMI: overweight (36% of patients; mean BMI, 28.7 kg/m2); class 1 obesity (40%; mean BMI, 33.7 kg/m2); class 2 obesity (19%; mean BMI, 39.9 kg/m2), and class 3 obesity (5%; mean BMI, 49.1 kg/m2).
The mean age of the individuals was 50 years, and 64% were White. Race/ethnicity data were unavailable for 31%. Asian Indian, Asian, and Black patients comprised 5% of the cohort.
“Strong significant gradient in heart failure risk”
Compared to the overweight (reference) group, the severe-obesity group comprised a higher percentage of women (74% vs. 70%), and the prevalence of comorbidities and socioeconomic deprivation was higher.
BMI remained relatively stable in each BMI group. The mean BMI increase was 1.06 kg/m2 during a median follow-up of 10.9 years.
There were 30,400 incident cases of CVD, 7,662 incident cases of heart failure, and 24,022 deaths, of which 2,827 (11.8%) were from CVD.
The risk for heart failure and CVD-related or all-cause mortality increased with increasing obesity severity.
Compared with overweight individuals, those with class 3 obesity were at significantly increased risk for heart failure (hazard ratio [HR], 3.26), all-cause mortality (HR, 2.72), and CVD-related mortality (HR, 3.31) after adjustment for age, sex, and comorbidities (hypertension, type 2 diabetes, atrial fibrillation, and chronic kidney disease).
The risk for stroke/TIA or coronary heart disease was similar among those with severe obesity and the other individuals. The risk for PVD was significantly lower (HR, 0.73).
The reduced risk for PVD in the most severely obese group is similar to findings in the Framingham heart study, the authors noted, and may be due to underdiagnosis or differences in the underlying mechanism.
Compelling evidence of poor health outcomes associated with obesity
Study limitations include the fact that the findings may not be generalizable to other race/ethnicity groups, the lack of information on diet and exercise, and the fact that BMI was used as a surrogate of adiposity. As such, it does not account for an age-related decrease in heavier-than-fat muscle mass and differences between sexes and ethnic groups.
The finding of stable obesity over time accords with two smaller studies that included Canadian and American adults.
The current study did not uncover an obesity paradox, unlike some studies that included patients with preexisting CVD or a history of acute coronary events. Those studies reported better clinical outcomes among patients with overweight or obesity.
The current study included individuals who did not initially have CVD. Those with more severe obesity were younger than individuals with overweight at the time of the occurrence of incident CVD (age 64 vs. 66) and at the age of death (age 67 vs. age 75), which “provides compelling evidence of poor health outcomes associated with obesity,” the authors emphasized.
“Further research is ... needed to explore whether interventions to change BMI trajectories would have an impact on future CVD outcomes,” they concluded.

In a U.K. cohort of more than 260,000 mostly middle-aged adults in primary care with overweight or obesity, body mass index remained relatively stable over a decade.
However, compared to overweight individuals, those with severe (class 3) obesity were more socioeconomically disadvantaged and had triple the risk for incident heart failure or all-cause or cardiovascular disease (CVD)–related mortality in a study published online April 15 in BMC Public Health.
“This is the first study to evaluate the long-term impact of overweight and obese individuals’ BMI trajectory on cardiovascular endpoints, heart failure, and mortality outcomes,” wrote Barbara Iyen, PhD, University of Nottingham, England, and colleagues.
The findings emphasize “the high cardiovascular toll exacted by continuing failure to tackle obesity, particularly among more socioeconomically deprived populations,” they warned.
“We have found that despite widespread efforts to prevent and manage obesity, the majority of adults who are overweight or obese in the general population continue to remain so in the long term,” Dr. Iyen said in a statement from her university.
“More effective policies and weight-management interventions are needed urgently to address this increasing burden and associated adverse health outcomes,” she stressed.
Invited to comment, Sadiya S. Khan, MD, Northwestern University, Chicago, said in an interview: “This research adds to the growing body of evidence [that] earlier and more intensive interventions for weight loss are necessary to promote cardiovascular health and reduce morbidity and mortality.
“Adjunctive pharmacotherapy and bariatric surgery are both options that should be considered in addition to intensive lifestyle interventions in overweight and obesity groups,” she added.
“I would always advocate for earlier prevention efforts focused on weight loss, because years lived with obesity are associated with future CVD, so every year counts,” Dr. Khan said.
Does BMI remain elevated, predict worse heart health?
Although obesity is a well-recognized risk factor for CVD, long-term changes in BMI and the impact of BMI on the risk for heart failure, CVD, and mortality have not been quantified among adults with overweight and obesity, Dr. Iyen and colleagues explained.
The researchers examined data from the UK Clinical Practice Research Datalink and secondary care and mortality records to determine BMI trajectories among adults with overweight or obesity and to quantify the risk for heart failure, CVD (defined as coronary heart disease, stroke, transient ischemic attack, or peripheral vascular disease, CVD-related mortality, and all-cause mortality.
They identified 264,230 adults with overweight or obesity who were seen in 790 primary care practices in the United Kingdom from 1999 to 2018 and who did not initially have heart failure or CVD and for whom baseline BMI measurements and at least one other BMI measurement 2, 5, 8, and 10 years later was available.
The researchers divided the cohort into four groups on the basis of initial BMI: overweight (36% of patients; mean BMI, 28.7 kg/m2); class 1 obesity (40%; mean BMI, 33.7 kg/m2); class 2 obesity (19%; mean BMI, 39.9 kg/m2), and class 3 obesity (5%; mean BMI, 49.1 kg/m2).
The mean age of the individuals was 50 years, and 64% were White. Race/ethnicity data were unavailable for 31%. Asian Indian, Asian, and Black patients comprised 5% of the cohort.

Pneumonia risk soars in heart failure patients, especially HFpEF
Patients with heart failure get pneumonia at a rate almost three times greater than expected and, once they do get pneumonia, have about a fourfold greater risk of death, investigators for a retrospective analysis of 13,000 patients from two landmark randomized HF trials have found.
The investigators also found that HF patients with preserved ejection fraction (HFpEF) are at the highest risk of developing pneumonia. The findings underscore the importance of patients with HF getting a pneumonia vaccination, they found.
The analysis showed that 6.3% of patients in the PARADIGM-HF trial and 10.6% of those in the PARAGON-HF trial developed pneumonia, reported the study authors, led by John J.V. McMurray, MD, of the British Heart Foundation Cardiovascular Research Center at the University of Glasgow in Scotland (J Am Coll Cardiol. 2021;77:1961-73).
“The main reason for doing this study was the fact that many heart failure patients are not vaccinated, as they should be, against pneumonia – both pneumococcus and influenza vaccination,” Dr. McMurray said in an interview. “We wanted to document the frequency and consequences of pneumonia in patients with heart failure to help highlight this deficiency in care.”
Dr. McMurray said he believes this is the first study to document the incidence of pneumonia and pneumonia-related outcomes according to the two major ejection fraction phenotypes.
PARADIGM-HF and PARAGON-HF
The post hoc analysis consisted of 8,399 patients with HF with reduced ejection fraction (HFrEF) in PARADIGM-HF (Eur J Heart Fail. 2013 Sep;15[9]:1062-73) and 4,796 patients with HFpEF in PARAGON-HF (N Engl J Med. 2014 Sep 11;371[11]:993-1004). The analysis focused on the 528 and 510 patients in each study, respectively, who developed pneumonia. Those rates translated to an incidence rate of 29 per 1,000 patient-years (95% confidence interval, 27-31) in PARADIGM-HF and 39 per 1,000 patient-years (95% CI, 36-42) in PARAGON-HF.
After pneumonia, the risk of death in patients increased substantially. In PARADIGM-HF, the adjusted hazard ratio for the risk of death from any cause after pneumonia was 4.34 (95% CI, 3.73-5.05). In PARAGON-HF, it was 3.76 (95% CI, 3.09-4.58). HF patients who contracted pneumonia also tended to have HF longer than their counterparts who didn’t develop pneumonia, but the frequency of previous hospitalization for HF didn’t vary between the pneumonia and no-pneumonia groups.
Patients who developed pneumonia tended to be older (average age of 66.9 years vs. 64.6 years, P < .001) and male (83.9% vs. 77.8%, P < .001). The mean age of patients in PARADIGM-HF was almost a decade younger than those in PARAGON-HF, 64 vs. 73 years.
Pneumonia patients also had worse Kansas City Cardiomyopathy Questionnaire scores (76 vs. 80 on average), but no difference in New York Heart Association functional class. “In general, patients who developed pneumonia had more symptoms and signs and HF than those who did not develop pneumonia,” Dr. McMurray and colleagues wrote.
Pneumonia patients also had higher rates of chronic obstructive pulmonary disease (26% vs. 12%), diabetes (43% vs. 34%), and atrial fibrillation (46% vs. 36%).
Another reason for conducting the study, Dr. McMurray said, “was the prior findings in patients with coronary disease and acute myocardial infarction that the risk associated with an episode of pneumonia [e.g., in subsequent vascular events and deaths] persisted long after the acute event. We wanted to see if this was also the case for heart failure, and indeed it was.”
For example, the adjusted HR for cardiovascular death or hospitalization in the first month following an episode of pneumonia was 9.48 (range of 6.85-13.12, P < .001), leveling off to 1.59 after 3 months or more.
Vaccination crucial in HF patients
Dr. McMurray noted that this study emphasizes the importance of pneumonia vaccination for patients with HF. “Given that we have so few treatments to offer patients with HFpEF, this makes the potential value of vaccination in these patients all the greater,” he said.
The COVID-19 pandemic, Dr. McMurray said, is a “good reminder of the dangers of a respiratory infection and the importance of vaccination in these patients. COVID-19 has interesting parallels in being a systemic disease and one with postacute, persisting effects.”
The persistent risk for adverse cardiovascular events 3 months and later after pneumonia is a novel finding of the study, wrote Donna Mancini, MD, and Gregory Gibson, MD, in an invited commentary (J Am Coll Cardiol. 2021;77:1974-6). Both are with the Icahn School of Medicine at Mt. Sinai in New York. The post hoc study also “serves as an important reminder” of pneumonia risk in patients with HF, especially during the pandemic, they wrote.
“Although vaccination alone appears unlikely to be a panacea, it is a readily accessible tool for mitigating disease severity and improving outcomes,” Dr. Mancini and Dr. Gibson wrote. “After all, an ounce of prevention is worth a pound of cure.”
Novartis provided funding for the PARADIGM-HF and PARAGON-HF trials, and Dr. McMurray and coauthors disclosed financial relationships with Novartis. Dr. Mancini and Dr. Gibson have no relevant financial relationships to disclose.

Medtronic recall of almost 240,000 ICDs is class I, FDA says
The Food and Drug Administration has declared Medtronic’s recall of seven models of defibrillating cardiac rhythm devices, caused by a risk for premature battery depletion, as class I, which implies a potential risk for serious injury or death. A total of 444 complaints, but no deaths, have been reported in association with the 239,171 affected devices, the agency said in a statement on April 12, 2021.
Physicians were notified of the company’s recall in early February. It covered implantable cardioverter defibrillator (ICD) and cardiac resynchronization therapy–defibrillator (CRT-D) models Evera, Viva, Brava, Claria, Amplia, Compia, and Visia distributed from Aug. 31, 2012 to May 9, 2018.
The devices could be subject to “an unexpected and rapid decrease in battery life” because of a possible short circuit that could lead to a device-replacement alert “earlier than expected.” Some devices may experience full battery depletion “within as little as 1 day” after such an alert.
“If the user does not respond to the first warning, the device may stop functioning. The likelihood that this issue will occur is constant after approximately 3 years after device use,” the announcement said.
Medtronic recommends device replacement no more than 1 week after such an early warning for patients who are not pacing dependent or who have them for primary prevention, but right away for pacing-dependent patients.

Physicians were notified of the company’s recall in early February. It covered implantable cardioverter defibrillator (ICD) and cardiac resynchronization therapy–defibrillator (CRT-D) models Evera, Viva, Brava, Claria, Amplia, Compia, and Visia distributed from Aug. 31, 2012 to May 9, 2018.
The devices could be subject to “an unexpected and rapid decrease in battery life” because of a possible short circuit that could lead to a device-replacement alert “earlier than expected.” Some devices may experience full battery depletion “within as little as 1 day” after such an alert.
“If the user does not respond to the first warning, the device may stop functioning. The likelihood that this issue will occur is constant after approximately 3 years after device use,” the announcement said.
Medtronic recommends device replacement no more than 1 week after such an early warning for patients who are not pacing dependent or who have them for primary prevention, but right away for pacing-dependent patients.

Remote cardio visits expand access for underserved during COVID
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.
“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.
“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.

OCS heart system earns hard-won backing of FDA panel
After more than 10 hours of intense debate, a Food and Drug Administration advisory panel gave its support to a premarket approval application (PMA) for the TransMedics Organ Care System (OCS) Heart system.
The OCS Heart is a portable extracorporeal perfusion and monitoring system designed to keep a donor heart in a normothermic, beating state. The “heart in a box” technology allows donor hearts to be transported across longer distances than is possible with standard cold storage, which can safely preserve donor hearts for about 4 hours.
The Circulatory System Devices Panel of the Medical Devices Advisory Committee voted 12 to 5, with 1 abstention, that the benefits of the OCS Heart System outweigh its risks.
The panel voted in favor of the OCS Heart being effective (10 yes, 6 no, and 2 abstaining) and safe (9 yes, 7 no, 2 abstaining) but not without mixed feelings.
James Blankenship, MD, a cardiologist at the University of New Mexico, Albuquerque, voted yes to all three questions but said: “If it had been compared to standard of care, I would have voted no to all three. But if it’s compared to getting an [left ventricular assist device] LVAD or not getting a heart at all, I would say the benefits outweigh the risks.”
Marc R. Katz, MD, chief of cardiothoracic surgery, Medical University of South Carolina, Charleston, also gave universal support, noting that the rate of heart transplantations has been flat for years. “This is a big step forward toward being able to expand that number. Now all that said, it obviously was a less-than-perfect study and I do think there needs to be some constraints put on the utilization.”
The panel reviewed data from the single-arm OCS Heart EXPAND trial and associated EXPAND Continued Access Protocol (CAP), as well the sponsor’s first OCS Heart trial, PROCEED II.
EXPAND met its effectiveness endpoint, with 88% of donor hearts successfully transplanted, an 8% incidence of severe primary graft dysfunction (PGD) 24 hours after transplantation, and 94.6% survival at 30 days.
Data from 41 patients with 30-day follow-up in the ongoing EXPAND CAP show 91% of donor hearts were utilized, a 2.4% incidence of severe PGD, and 100% 30-day survival.
The sponsor and the FDA clashed over changes made to the trial after the PMA was submitted, the appropriateness of the effectiveness outcome, and claims by the FDA that there was substantial overlap in demographic characteristics between the extended criteria donor hearts in the EXPAND trials and the standard criteria donor hearts in PROCEED II.
TransMedics previously submitted a PMA based on PROCEED II but it noted in submitted documents that it was withdrawn because of “fundamental disagreements with FDA” on the interpretation of a post hoc analysis with United Network for Organ Sharing registry data that identified increased all-cause mortality risk but comparable cardiac-related mortality in patients with OCS hearts.
During the marathon hearing, FDA officials presented several post hoc analyses, including one stratified by donor inclusion criteria, in which 30-day survival estimates were worse in recipients of single-criterion organs than for those receiving donor organs with multiple inclusion criteria (85% vs. 91.4%). In a second analysis, 2-year point estimates of survival also trended lower with donor organs having only one extended criterion.
Reported EXPAND CAP 6- and 12-month survival estimates were 100% and 93%, respectively, which was higher than EXPAND (93% and 84%), but there was substantial censoring (>50%) at 6 months and beyond, FDA officials said.
When EXPAND and CAP data were pooled, modeled survival curves shifted upward but there was a substantial site effect, with a single site contributing 46% of data, which may affect generalizability of the results, they noted.
“I voted yes for safety, no for efficacy, and no for approval and I’d just like to say I found this to be the most difficult vote in my experience on this panel,” John Hirshfeld, MD, University of Pennsylvania, Philadelphia, said. “I was very concerned that the PROCEED data suggests a possible harm, and in the absence of an interpretable comparator for the EXPAND trial, it’s really not possible to decide if there’s efficacy.”
Keith B. Allen, MD, director of surgical research at Saint Luke’s Hospital of Kansas City (Mo.), said, “I voted no on safety; I’m not going to give the company a pass. I think their animal data was sorely lacking and a lot of issues over the last 10 years could have been addressed with some key animal studies.
“For efficacy and risk/benefit, I voted yes for both,” he said. “Had this been standard of care and only PROCEED II, I would have voted no, but I do think there are a lot of hearts that go in the bucket and this is a challenging population.”
More than a dozen physicians and patients spoke at the open public hearing about the potential for the device to expand donor heart utilization, including a recipient whose own father died while waiting on the transplant list. Only about 3 out of every 10 donated hearts are used for transplant. To ensure fair access, particularly for patients in rural areas, federal changes in 2020 mandate that organs be allocated to the sickest patients first.
Data showed that the OCS Heart System was associated with shorter waiting list times, compared with U.S. averages but longer preservation times than cold static preservation.
In all, 13% of accepted donor organs were subsequently turned down after OCS heart preservation. Lactate levels were cited as the principal reason for turn-down but, FDA officials said, the validity of using lactate as a marker for transplantability is unclear.
Pathologic analysis of OCS Heart turned-down donor hearts with stable antemortem hemodynamics, normal or near-normal anatomy and normal ventricular function by echocardiography, and autopsy findings of acute diffuse or multifocal myocardial damage “suggest that in an important proportion of cases the OCS Heart system did not provide effective organ preservation or its use caused severe myocardial damage to what might have been an acceptable graft for transplant,” said Andrew Farb, MD, chief medical officer of the FDA’s Office of Cardiovascular Devices.
Proposed indication
In the present PMA, the OCS Heart System is indicated for donor hearts with one or more of the following characteristics: an expected cross-clamp or ischemic time of at least 4 hours because of donor or recipient characteristics; or an expected total cross-clamp time of at least 2 hours plus one of the following risk factors: donor age 55 or older, history of cardiac arrest and downtime of at least 20 minutes, history of alcoholism, history of diabetes, donor ejection fraction of 40%-50%,history of left ventricular hypertrophy, and donor angiogram with luminal irregularities but no significant coronary artery disease
Several members voiced concern about “indication creep” should the device be approved by the FDA, and highlighted the 2-hour cross-clamp time plus wide-ranging risk factors.
“I’m a surgeon and I voted no on all three counts,” said Murray H. Kwon, MD, Ronald Reagan University of California, Los Angeles Medical Center. “As far as risk/benefit, if it was just limited to one group – the 4-hour plus – I would say yes, but if you’re going to tell me that there’s a risk/benefit for the 2-hour with the alcoholic, I don’t know how that was proved in anything.”
Dr. Kwon was also troubled by lack of proper controls and by the one quarter of patients who ended up on mechanical circulatory support in the first 30 days after transplant. “I find that highly aberrant.”
Joaquin E. Cigarroa, MD, head of cardiovascular medicine, Oregon Health & Science University, Portland, said the unmet need for patients with refractory, end-stage heart failure is challenging and quite emotional, but also voted no across the board, citing concerns about a lack of comparator in the EXPAND trials and overall out-of-body ischemic time.
“As it relates to risk/benefit, I thought long and hard about voting yes despite all the unknowns because of this emotion, but ultimately I voted no because of the secondary 2-hours plus alcoholism, diabetes, or minor coronary disease, in which the ischemic burden and ongoing lactate production concern me,” he said.
Although the panel decision is nonbinding, there was strong support from the committee members for a randomized, postapproval trial and more complete animal studies.

Pathologic analysis of OCS Heart turned-down donor hearts with stable antemortem hemodynamics, normal or near-normal anatomy and normal ventricular function by echocardiography, and autopsy findings of acute diffuse or multifocal myocardial damage “suggest that in an important proportion of cases the OCS Heart system did not provide effective organ preservation or its use caused severe myocardial damage to what might have been an acceptable graft for transplant,” said Andrew Farb, MD, chief medical officer of the FDA’s Office of Cardiovascular Devices.
Proposed indication
In the present PMA, the OCS Heart System is indicated for donor hearts with one or more of the following characteristics: an expected cross-clamp or ischemic time of at least 4 hours because of donor or recipient characteristics; or an expected total cross-clamp time of at least 2 hours plus one of the following risk factors: donor age 55 or older, history of cardiac arrest and downtime of at least 20 minutes, history of alcoholism, history of diabetes, donor ejection fraction of 40%-50%,history of left ventricular hypertrophy, and donor angiogram with luminal irregularities but no significant coronary artery disease
Several members voiced concern about “indication creep” should the device be approved by the FDA, and highlighted the 2-hour cross-clamp time plus wide-ranging risk factors.
“I’m a surgeon and I voted no on all three counts,” said Murray H. Kwon, MD, Ronald Reagan University of California, Los Angeles Medical Center. “As far as risk/benefit, if it was just limited to one group – the 4-hour plus – I would say yes, but if you’re going to tell me that there’s a risk/benefit for the 2-hour with the alcoholic, I don’t know how that was proved in anything.”
Dr. Kwon was also troubled by lack of proper controls and by the one quarter of patients who ended up on mechanical circulatory support in the first 30 days after transplant. “I find that highly aberrant.”
Joaquin E. Cigarroa, MD, head of cardiovascular medicine, Oregon Health & Science University, Portland, said the unmet need for patients with refractory, end-stage heart failure is challenging and quite emotional, but also voted no across the board, citing concerns about a lack of comparator in the EXPAND trials and overall out-of-body ischemic time.
“As it relates to risk/benefit, I thought long and hard about voting yes despite all the unknowns because of this emotion, but ultimately I voted no because of the secondary 2-hours plus alcoholism, diabetes, or minor coronary disease, in which the ischemic burden and ongoing lactate production concern me,” he said.
Although the panel decision is nonbinding, there was strong support from the committee members for a randomized, postapproval trial and more complete animal studies.

After more than 10 hours of intense debate, a Food and Drug Administration advisory panel gave its support to a premarket approval application (PMA) for the TransMedics Organ Care System (OCS) Heart system.
The OCS Heart is a portable extracorporeal perfusion and monitoring system designed to keep a donor heart in a normothermic, beating state. The “heart in a box” technology allows donor hearts to be transported across longer distances than is possible with standard cold storage, which can safely preserve donor hearts for about 4 hours.
The Circulatory System Devices Panel of the Medical Devices Advisory Committee voted 12 to 5, with 1 abstention, that the benefits of the OCS Heart System outweigh its risks.
The panel voted in favor of the OCS Heart being effective (10 yes, 6 no, and 2 abstaining) and safe (9 yes, 7 no, 2 abstaining) but not without mixed feelings.
James Blankenship, MD, a cardiologist at the University of New Mexico, Albuquerque, voted yes to all three questions but said: “If it had been compared to standard of care, I would have voted no to all three. But if it’s compared to getting an [left ventricular assist device] LVAD or not getting a heart at all, I would say the benefits outweigh the risks.”
Marc R. Katz, MD, chief of cardiothoracic surgery, Medical University of South Carolina, Charleston, also gave universal support, noting that the rate of heart transplantations has been flat for years. “This is a big step forward toward being able to expand that number. Now all that said, it obviously was a less-than-perfect study and I do think there needs to be some constraints put on the utilization.”
The panel reviewed data from the single-arm OCS Heart EXPAND trial and associated EXPAND Continued Access Protocol (CAP), as well the sponsor’s first OCS Heart trial, PROCEED II.
EXPAND met its effectiveness endpoint, with 88% of donor hearts successfully transplanted, an 8% incidence of severe primary graft dysfunction (PGD) 24 hours after transplantation, and 94.6% survival at 30 days.
Data from 41 patients with 30-day follow-up in the ongoing EXPAND CAP show 91% of donor hearts were utilized, a 2.4% incidence of severe PGD, and 100% 30-day survival.
The sponsor and the FDA clashed over changes made to the trial after the PMA was submitted, the appropriateness of the effectiveness outcome, and claims by the FDA that there was substantial overlap in demographic characteristics between the extended criteria donor hearts in the EXPAND trials and the standard criteria donor hearts in PROCEED II.
TransMedics previously submitted a PMA based on PROCEED II but it noted in submitted documents that it was withdrawn because of “fundamental disagreements with FDA” on the interpretation of a post hoc analysis with United Network for Organ Sharing registry data that identified increased all-cause mortality risk but comparable cardiac-related mortality in patients with OCS hearts.
During the marathon hearing, FDA officials presented several post hoc analyses, including one stratified by donor inclusion criteria, in which 30-day survival estimates were worse in recipients of single-criterion organs than for those receiving donor organs with multiple inclusion criteria (85% vs. 91.4%). In a second analysis, 2-year point estimates of survival also trended lower with donor organs having only one extended criterion.
Reported EXPAND CAP 6- and 12-month survival estimates were 100% and 93%, respectively, which was higher than EXPAND (93% and 84%), but there was substantial censoring (>50%) at 6 months and beyond, FDA officials said.
When EXPAND and CAP data were pooled, modeled survival curves shifted upward but there was a substantial site effect, with a single site contributing 46% of data, which may affect generalizability of the results, they noted.
“I voted yes for safety, no for efficacy, and no for approval and I’d just like to say I found this to be the most difficult vote in my experience on this panel,” John Hirshfeld, MD, University of Pennsylvania, Philadelphia, said. “I was very concerned that the PROCEED data suggests a possible harm, and in the absence of an interpretable comparator for the EXPAND trial, it’s really not possible to decide if there’s efficacy.”
Keith B. Allen, MD, director of surgical research at Saint Luke’s Hospital of Kansas City (Mo.), said, “I voted no on safety; I’m not going to give the company a pass. I think their animal data was sorely lacking and a lot of issues over the last 10 years could have been addressed with some key animal studies.
“For efficacy and risk/benefit, I voted yes for both,” he said. “Had this been standard of care and only PROCEED II, I would have voted no, but I do think there are a lot of hearts that go in the bucket and this is a challenging population.”
More than a dozen physicians and patients spoke at the open public hearing about the potential for the device to expand donor heart utilization, including a recipient whose own father died while waiting on the transplant list. Only about 3 out of every 10 donated hearts are used for transplant. To ensure fair access, particularly for patients in rural areas, federal changes in 2020 mandate that organs be allocated to the sickest patients first.
Data showed that the OCS Heart System was associated with shorter waiting list times, compared with U.S. averages but longer preservation times than cold static preservation.
In all, 13% of accepted donor organs were subsequently turned down after OCS heart preservation. Lactate levels were cited as the principal reason for turn-down but, FDA officials said, the validity of using lactate as a marker for transplantability is unclear.

Eating fish tied to fewer CVD events in high-risk people
People with cardiovascular disease who regularly ate fish had significantly fewer major CVD events and there were fewer total deaths, compared with similar individuals who didn’t eat fish, but there was no beneficial link from eating fish among the general population in prospective data collected from more than 191,000 people from 58 countries.
Despite the neutral finding among people without CVD, the finding that eating fish was associated with significant benefit for those with CVD or who were at high risk for CVD confirms the public health importance of regular fish or fish oil consumption, said one expert.
A little over a quarter of those included in the new study had a history of CVD or were at high risk for CVD. In this subgroup of more than 51,000 people, those who consumed on average at least two servings of fish weekly (at least 175 g, or about 6.2 ounces per week) had a significant 16% lower rate of major CVD events during a median follow-up of about 7.5 years.
The rate of all-cause death was a significant 18% lower among people who ate two or more fish portions weekly, compared with those who didn’t, Deepa Mohan, PhD, and associates wrote in their report in JAMA Internal Medicine.
The researchers saw no additional benefit when people regularly ate greater amounts of fish.
“There is a significant protective benefit of fish consumption in people with cardiovascular disease,” said Andrew Mente, PhD, a senior investigator on the study and an epidemiologist at McMaster University, Hamilton, Ont..
“This study has important implications for guidelines on fish intake globally. It indicates that increasing fish consumption and particularly oily fish in vascular patients may produce a modest cardiovascular benefit,” he said in a statement released by McMaster.
‘A large body of evidence’ for CVD benefit
The neutral finding of no significant benefit (as well as no harm) regarding either CVD events or total mortality among people without CVD “does not alter the large body of prior observational evidence supporting the cardiac benefits of fish intake in general populations,” noted Dariush Mozaffarian, MD, DrPH, in a commentary that accompanies the report by Dr. Mohan and colleagues.
Although the new analysis failed to show a significant association between regular fish consumption and fewer CVD events for people without established CVD or CVD risk, “based on the cumulative evidence from prospective observational studies, randomized clinical trials, and mechanistic and experimental studies, modest fish consumption appears to have some cardiac benefits,” he added.
“Adults should aim to consume about two servings of fish per week, and larger benefits may accrue from nonfried oily (dark meat) fish,” wrote Dr. Mozaffarian, a professor of medicine and nutrition at Tufts University, Boston.
Oily, dark fishes include salmon, tuna steak, mackerel, herring, and sardines. Species such as these contain the highest levels of long-chain omega-3 fatty acids, eicosapentaenoic acid, and docosapentaenoic acid; these nutrients likely underlie the CVD benefits from fish, Dr. Mozaffarian said in an interview with JAMA Internal Medicine that accompanied his commentary. (Dr. Mente also participated.)
“Fish oil lowers heart rate, blood pressure, and triglycerides (at high dosages), increases adiponectin, improves endothelial function, and in some studies improves oxygen consumption in myocardium. If there is benefit from fish it’s from the omega 3s, and all in all the evidence supports this,” but because the evidence is primarily observational, it can only show linkage and cannot prove causation, he explained.
Given the potential benefit and limited risk, “I think everyone should aim to eat two servings of fish each week, preferentially oily fish. That’s very solid,” said Dr. Mozaffarian, who is also a cardiologist and dean of the Tufts Friedman School of Nutrition Science.
The investigators did not have adequate data to compare the associations between outcomes and a diet with oily fish versus less oily fish.
OTC fish oil capsules are ‘very reasonable’
For people who either can’t consume two fish meals a week or want to ensure their omega 3 intake is adequate, “it’s very reasonable for the average person to take one OTC [over-the-counter] fish oil capsule a day,” Dr. Mozaffarian added.
He acknowledged that several studies of fish oil supplements failed to show benefit, but several others have. “It’s a confusing field, but the evidence supports benefit from omega 3s,” he concluded.
He discounted the new finding that only people with established CVD or who are at high-risk benefit. “I’m not sure we should make too much of this, because many prior studies showed a lower CVD risk in fish-eating people without prevalent CVD,” he said. The new study “provides important information given its worldwide breadth.”
The new report used data regarding 191,558 people enrolled prospectively in any of four studies. The average age of the participants was 54 years, and 52% were women.
During follow-up, death from any cause occurred in 6% of those without CVD or CVD risk and in 13% of those with these factors. Major CVD events occurred in 5% and 17% of these two subgroups, respectively. To calculate the relative risks between those who ate fish and those who did not, the investigators used standard multivariate adjustment for potential confounders and adjusted for several dietary variables, Dr. Mente said.
Dr. Mohan and Dr. Mente disclosed no relevant financial relationships. Dr. Mozaffarian has received personal fees from Acasti Pharma, Amarin, America’s Test Kitchen, Barilla, Danone, GEOD, and Motif Food Works, and he has been an adviser to numerous companies.

Inpatient sodium imbalances linked to adverse COVID-19 outcomes
Both high and low serum sodium levels are associated with adverse outcomes for hospitalized patients with COVID-19, new research suggests.
In the retrospective study of 488 patients hospitalized with COVID-19 at one of two London hospitals between February and May 2020, hypernatremia (defined as serum sodium level >145 mmol/L) at any time point during hospital stay was associated with a threefold increase in inpatient mortality.
Hyponatremia (serum sodium level <135 mmol/L) was associated with twice the likelihood of requiring advanced ventilatory support. In-hospital mortality was also increased among patients with hypovolemic hyponatremia.
“Serum sodium values could be used in clinical practice to identify patients with COVID-19 at high risk of poor outcomes who would benefit from more intensive monitoring and judicious rehydration,” Ploutarchos Tzoulis, MD, PhD, and colleagues wrote in their article, which was published online on Feb. 24, 2021, in the Journal of Clinical Endocrinology and Metabolism.
The findings will be presented at the upcoming news conference held by the Endocrine Society
Should sodium be included in a risk calculator for COVID-19?
Dr. Tzoulis, professor of endocrinology at the University College London Medical School, said in an interview that “sodium could be incorporated in risk calculators across other routine biomarkers, such as white cell count, lymphocytes, and CRP [C-reactive protein], in order to provide a tool for dynamic risk stratification throughout the clinical course of COVID-19 and assist clinical decision-making.”
Moreover, he said, “we should follow less conservative strategies in the rate and amount of fluid resuscitation in order to prevent hypernatremia, which is induced by negative fluid balance and can often be iatrogenic.”
Asked to comment, Steven Q. Simpson, MD, professor of medicine in the division of pulmonary, critical care, and sleep medicine at the University of Kansas, Kansas City, said that the article is missing key results that would assist in interpreting of the findings.
“Data regarding diuretic use and sparing of fluid administration are not in the paper. ... It is simply not possible to tell whether serum sodium is a ‘predictor’ ... or if it is a side effect of other issues or actions taken by physicians in patients who are progressing poorly.
“To say that sodium needs to be included in a risk calculator is to subtly suggest that there is some causal association with mortality, and that has quite clearly not been established,” stressed Dr. Simpson, who is president of the American College of Chest Physicians but was not speaking for the organization.
He added: “The data are interesting, but not actionable. It is common practice in critical care medicine to adjust water and salt intake to maintain serum sodium within the normal range, so the paper really doesn’t change any behavior.”
Dr. Tzoulis said in an interview that, despite not having electronic medical record data on diuretic use or fluid input and output, “our acute physicians and intensivists at both study sites have been adamant that they’ve not routinely used diuretics in COVID-19 patients. Diuretics have been sparingly used in our cohort, and also the frequency of pulmonary edema was reported as below 5%.”
Regarding volume of fluid intake, Dr. Tzoulis noted, “At our hospital sites, the strategy has been that of cautious fluid resuscitation. In fact, the amount of fluid given has been reported by our physicians and intensivists as ‘on purpose much more conservative than the usual one adopted in patients with community-acquired pneumonia at risk of respiratory failure.’ ”
Hyper- and hyponatremia linked to adverse COVID-19 outcomes
In the study, 5.3% of the 488 patients had hypernatremia at hospital presentation, and 24.6% had hyponatremia. Of note, only 19% of those with hyponatremia underwent laboratory workup to determine the etiology. Of those, three quarters had hypovolemic hyponatremia, determined on the basis of a urinary sodium cutoff of 30 mmol/L.
The total in-hospital mortality rate was 31.1%. There was a strong, although nonsignificant, trend toward higher mortality in association with sodium status at admission. Death rates were 28.4%, 30.8%, and 46.1% for those who were normonatremic, hyponatremic, and hypernatremic, respectively (P = .07). Baseline serum sodium levels didn’t differ between survivors (137 mmol/L) and nonsurvivors (138 mmol/L).
In multivariable analysis, the occurrence of hypernatremia at any point during the first 5 days in the hospital was among three independent risk factors for higher in-hospital mortality (adjusted hazard ratio, 2.74; P = .02). The other risk factors were older age and higher CRP level.
Overall, hyponatremia was not associated with death (P = .41).
During hospitalization, 37.9% of patients remained normonatremic; 36.9% experienced hyponatremia; 10.9% had hypernatremia; and 14.3% had both conditions at some point during their stay.
In-hospital mortality was 21% among those with normonatremia, compared with 56.6% for those with hypernatremia (odds ratio, 3.05; P = .0038) and 45.7% for those with both (OR, 2.25; P < .0001).
The 28.3% mortality rate in the overall group that experienced hyponatremia didn’t differ significantly from the 21.1% in the normonatremic group (OR, 1.34; P = .16). However, the death rate was 40.9% among the subgroup that developed hypovolemic hyponatremia, significantly higher than the normonatremic group (OR, 2.59, P = .0017).
The incidence of hyponatremia decreased from 24.6% at admission to 14.1% 5 days later, whereas the frequency of hypernatremia rose from 5.3% to 13.8%.
Key finding: Link between hospital-acquired hypernatremia and death
“The key novel finding of our study was that hospital-acquired hypernatremia, rather than hypernatremia at admission, was a predictor for in-hospital mortality, with the worst prognosis being reported in patients with the largest increase in serum sodium in the first 5 days of hospitalization,” noted Dr. Tzoulis and colleagues.
Hypernatremia was present in 29.6% of nonsurvivors, compared with 5.2% in survivors.
Among 120 patients with hyponatremia at admission, 31.7% received advanced respiratory support, compared with 17.5% and 7.7% of those with normonatremia or hypernatremia, respectively (OR, 2.18; P = .0011).
In contrast, there was no difference in the proportions needing ventilatory support between those with hypernatremia and those with normonatremia (16.7% vs. 12.4%; OR, 1.44; P = .39).
Acute kidney injury occurred in 181 patients (37.1%). It was not related to serum sodium concentration at any time point.
Dr. Tzoulis and Dr. Simpson disclosed no relevant financial relationships.

In the retrospective study of 488 patients hospitalized with COVID-19 at one of two London hospitals between February and May 2020, hypernatremia (defined as serum sodium level >145 mmol/L) at any time point during hospital stay was associated with a threefold increase in inpatient mortality.
Hyponatremia (serum sodium level <135 mmol/L) was associated with twice the likelihood of requiring advanced ventilatory support. In-hospital mortality was also increased among patients with hypovolemic hyponatremia.
“Serum sodium values could be used in clinical practice to identify patients with COVID-19 at high risk of poor outcomes who would benefit from more intensive monitoring and judicious rehydration,” Ploutarchos Tzoulis, MD, PhD, and colleagues wrote in their article, which was published online on Feb. 24, 2021, in the Journal of Clinical Endocrinology and Metabolism.
The findings will be presented at the upcoming news conference held by the Endocrine Society
Should sodium be included in a risk calculator for COVID-19?
Dr. Tzoulis, professor of endocrinology at the University College London Medical School, said in an interview that “sodium could be incorporated in risk calculators across other routine biomarkers, such as white cell count, lymphocytes, and CRP [C-reactive protein], in order to provide a tool for dynamic risk stratification throughout the clinical course of COVID-19 and assist clinical decision-making.”
Moreover, he said, “we should follow less conservative strategies in the rate and amount of fluid resuscitation in order to prevent hypernatremia, which is induced by negative fluid balance and can often be iatrogenic.”
Asked to comment, Steven Q. Simpson, MD, professor of medicine in the division of pulmonary, critical care, and sleep medicine at the University of Kansas, Kansas City, said that the article is missing key results that would assist in interpreting of the findings.
“Data regarding diuretic use and sparing of fluid administration are not in the paper. ... It is simply not possible to tell whether serum sodium is a ‘predictor’ ... or if it is a side effect of other issues or actions taken by physicians in patients who are progressing poorly.
“To say that sodium needs to be included in a risk calculator is to subtly suggest that there is some causal association with mortality, and that has quite clearly not been established,” stressed Dr. Simpson, who is president of the American College of Chest Physicians but was not speaking for the organization.
He added: “The data are interesting, but not actionable. It is common practice in critical care medicine to adjust water and salt intake to maintain serum sodium within the normal range, so the paper really doesn’t change any behavior.”
Dr. Tzoulis said in an interview that, despite not having electronic medical record data on diuretic use or fluid input and output, “our acute physicians and intensivists at both study sites have been adamant that they’ve not routinely used diuretics in COVID-19 patients. Diuretics have been sparingly used in our cohort, and also the frequency of pulmonary edema was reported as below 5%.”
Regarding volume of fluid intake, Dr. Tzoulis noted, “At our hospital sites, the strategy has been that of cautious fluid resuscitation. In fact, the amount of fluid given has been reported by our physicians and intensivists as ‘on purpose much more conservative than the usual one adopted in patients with community-acquired pneumonia at risk of respiratory failure.’ ”
Hyper- and hyponatremia linked to adverse COVID-19 outcomes
In the study, 5.3% of the 488 patients had hypernatremia at hospital presentation, and 24.6% had hyponatremia. Of note, only 19% of those with hyponatremia underwent laboratory workup to determine the etiology. Of those, three quarters had hypovolemic hyponatremia, determined on the basis of a urinary sodium cutoff of 30 mmol/L.
The total in-hospital mortality rate was 31.1%. There was a strong, although nonsignificant, trend toward higher mortality in association with sodium status at admission. Death rates were 28.4%, 30.8%, and 46.1% for those who were normonatremic, hyponatremic, and hypernatremic, respectively (P = .07). Baseline serum sodium levels didn’t differ between survivors (137 mmol/L) and nonsurvivors (138 mmol/L).
In multivariable analysis, the occurrence of hypernatremia at any point during the first 5 days in the hospital was among three independent risk factors for higher in-hospital mortality (adjusted hazard ratio, 2.74; P = .02). The other risk factors were older age and higher CRP level.
Overall, hyponatremia was not associated with death (P = .41).
During hospitalization, 37.9% of patients remained normonatremic; 36.9% experienced hyponatremia; 10.9% had hypernatremia; and 14.3% had both conditions at some point during their stay.
In-hospital mortality was 21% among those with normonatremia, compared with 56.6% for those with hypernatremia (odds ratio, 3.05; P = .0038) and 45.7% for those with both (OR, 2.25; P < .0001).
The 28.3% mortality rate in the overall group that experienced hyponatremia didn’t differ significantly from the 21.1% in the normonatremic group (OR, 1.34; P = .16). However, the death rate was 40.9% among the subgroup that developed hypovolemic hyponatremia, significantly higher than the normonatremic group (OR, 2.59, P = .0017).
The incidence of hyponatremia decreased from 24.6% at admission to 14.1% 5 days later, whereas the frequency of hypernatremia rose from 5.3% to 13.8%.
Key finding: Link between hospital-acquired hypernatremia and death
“The key novel finding of our study was that hospital-acquired hypernatremia, rather than hypernatremia at admission, was a predictor for in-hospital mortality, with the worst prognosis being reported in patients with the largest increase in serum sodium in the first 5 days of hospitalization,” noted Dr. Tzoulis and colleagues.
Hypernatremia was present in 29.6% of nonsurvivors, compared with 5.2% in survivors.
Among 120 patients with hyponatremia at admission, 31.7% received advanced respiratory support, compared with 17.5% and 7.7% of those with normonatremia or hypernatremia, respectively (OR, 2.18; P = .0011).
In contrast, there was no difference in the proportions needing ventilatory support between those with hypernatremia and those with normonatremia (16.7% vs. 12.4%; OR, 1.44; P = .39).
Acute kidney injury occurred in 181 patients (37.1%). It was not related to serum sodium concentration at any time point.
Dr. Tzoulis and Dr. Simpson disclosed no relevant financial relationships.

Obesity: A ‘double hit’ in pregnant women with heart disease
Being obese and pregnant raises the risk for cardiac complications in women with preexisting heart disease, new research suggests, highlighting the need for earlier interventions in this high-risk population.
The analysis of 790 pregnancies revealed that 23% of women with obesity, defined as body mass index greater than 30 kg/m2, had a cardiac event during pregnancy versus 14% of women with normal body weight (P = .006).
The difference was driven largely by an increase in heart failure (8% vs. 3%; P = .02), although arrhythmias also trended higher in obese women (14% vs. 10%; P = .19).
Nearly half of the women with obesity and a cardiac event presented in the postpartum period (47%).
In multivariate analysis, both obesity and Canadian Cardiac Disease in Pregnancy Study (CARPREG) II risk score were independent predictors of cardiac events (odds ratios for both, 1.7), the investigators, led by Birgit Pfaller, MD, University of Toronto, reported in the Journal of the American College of Cardiology.
Although obesity has been linked to worse pregnancy outcomes and higher cardiovascular risk after delivery in the general population, the authors noted that this is the first study to examine its effect on outcomes in women with heart disease.
“We wanted to look at this high-risk group of women that had preexisting heart disease, but in addition had obesity, to try and find out if there was a kind of double hit for these women – and that, in the end, is what we found. It’s not just simply having heart disease, not simply having obesity, but the combination that’s problematic,” senior author and cardiologist Candice Silversides, MD, University of Toronto, said in an interview.
The findings are concerning given the rising prevalence of obesity worldwide. National data from 2018 show that slightly more than half of women who gave birth in the United States were significantly overweight or obese before becoming pregnant.
Similarly, in the present analysis of 600 women in the CARPREG study who gave birth from 2004 to 2014, nearly 1 in 5 pregnancies (19%) occurred in women with obesity and 25% were in overweight women.
Obese women were significantly more likely than those without obesity to have coronary artery disease (6% vs. 2%), cardiomyopathies (19% vs. 8%) and left ventricular dysfunction (19% vs. 12%) and to be hypertensive or have a hypertensive disorder of pregnancy (13% vs. 3%).
Preeclampsia developed in 32 women during the index pregnancy and 69% of these women were obese or overweight. Cardiac event rates were similar in women with or without preeclampsia but trended higher in women with preeclampsia with versus without obesity (36% vs. 14%; P = .20).
The ill effects of obesity were also reflected in fetal and neonatal events. Overall, 43% of women with obesity and 33% of normal-weight women had at least one fetal event (P = .02), with higher rates of preterm birth (19% vs. 10%; P = .005) and respiratory distress syndrome (8% vs. 3%; P = .02) in women with obesity. Congenital cardiac malformations were present in 6% of women in both groups.
Taken together, the composite of cardiac events, preeclampsia, or fetal events was significantly more common in women with obesity than in normal-weight women (56% vs. 41%; P = .002).
“We’ve spent the last number of years trying to research and understand what the drivers of these adverse outcomes are in this high-risk pregnant cohort, but on a bigger picture the real issue is how do we start intervening in a meaningful way,” Dr. Silversides said.
Like many in the burgeoning field of cardio-obstetrics, the team proposed a multidisciplinary approach that stresses preconception counseling, educating pregnant women with heart disease and obesity about their risks, ensuring that dietary advice, weight-gain recommendations, and comorbidities are addressed as part of routine care, and providing postpartum surveillance.
Preconception screening “has been the recommendation for a long, long time; it’s just that it doesn’t always happen in reality,” she said. “Many pregnancies aren’t planned and not all women are filtered into preconception counseling. So sometimes you’ll do it at the first antenatal visit and try to ensure women are educated but optimally you want to do it well in advance of pregnancy.”
Part of that preconception counseling “should also include giving them appropriate advice for contraception, if what they want to do is avoid pregnancy,” added Dr. Silversides.
Garima Sharma, MD, Ciccarone Center for the Prevention of Cardiovascular Disease, Johns Hopkins University, Baltimore, and colleagues wrote in an accompanying editorial that the adverse events observed in this high-risk cohort have “important implications for cardio-obstetricians and should be incorporated in routine prepregnancy and antenatal counseling, monitoring, and risk stratification for women with existing cardiovascular disease.”
They pointed to a paucity of data incorporating maternal prepregnancy obesity and gestational weight gain in risk prediction and called for larger population-based studies on the additive impact of obesity severity on predicting adverse cardiac events in women with existing cardiovascular disease.
Randomized trials are also urgently needed to evaluate the effect of nutritional and behavioral interventions in pregnancy on short- and long-term outcomes in mother and child.
“As the obesity epidemic continues to grow and public health interventions promoting lifestyle changes for obesity management remain a major challenge, maternal obesity may prove to be the ‘Achilles’ heel’ of sustainable national efforts to reduce maternal mortality and improve health equity. This is a call to action,” Dr. Sharma and colleagues concluded.
The investigators noted that the study was conducted at a single center and used self-reported pregnancy weight collected at the first antenatal visit, which may have underestimated obesity rates. Other limitations are that weight changes over the course of pregnancy were not studied and there was a limited number of women with a body mass index of 40 or higher.
The study was supported by a grant from the Allan E. Tiffin Trust, Toronto General and Western Hospital Foundation, and by a donation from Mrs. Josephine Rogers, Toronto General Hospital. Dr. Silversides is supported by the Miles Nadal Chair in Pregnancy and Heart Disease. Dr. Sharma and colleagues disclosed no relevant financial relationships.
