SARS-CoV-2 Cardiac Involvement in Young Competitive Athletes.

ABSTRACT: Background: Cardiac involvement among hospitalized patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is common and associated with adverse outcomes. The objective of this study was to determine the prevalence and clinical implications of SARS-CoV-2 cardiac involvement in young competitive athletes. Methods: In this prospective multicenter observational cohort study with data from 42 colleges/universities, we assessed the prevalence, clinical characteristics, and outcomes of SARS-CoV-2 cardiac involvement among collegiate athletes in the United States. Data were collected from September 1, 2020 to December 31, 2020. The primary outcome was the prevalence of definite, probable, or possible SARS-CoV-2 cardiac involvement based on imaging definitions adapted from the Updated Lake Louise Criteria. Secondary outcomes included the diagnostic yield of cardiac testing, predictors for cardiac involvement, and adverse cardiovascular events or hospitalizations. Results: Among 19,378 athletes tested for SARS-CoV-2 infection, 3018 (mean age 20 years [SD,1 year]; 32% female) tested positive and underwent cardiac evaluation. A total of 2820 athletes underwent at least one element of cardiac 'triad' testing [12-lead electrocardiography (ECG), troponin, and/or transthoracic echocardiography(TTE)] followed by cardiac magnetic resonance (CMR) if clinically indicated. In contrast, primary screening CMR was performed in 198 athletes. Abnormal findings suggestive of SARS-CoV-2 cardiac involvement were detected by ECG (21/2999,0.7%), cardiac troponin (24/2719,0.9%), and TTE (24/2556,0.9%). Definite, probable, or possible SARS-COV-2 cardiac involvement was identified in 21/3018 (0.7%) athletes, including 15/2820 (0.5%) who underwent clinically indicated CMR (n=119) and 6/198 (3.0%) who underwent primary screening CMR. Accordingly, the diagnostic yield of CMR for SARS-COV-2 cardiac involvement was 4.2 times higher for a clinically indicated CMR (15/119,12.6%) versus a primary screening CMR (6/198,3.0%). After adjustment for race and sex, predictors of SARS-CoV-2 cardiac involvement included cardiopulmonary symptoms (OR:3.1,95% CI:1.2,7.7) or at least one abnormal triad test (OR:37.4,95% CI:13.3,105.3). Five (0.2%) athletes required hospitalization for non-cardiac complications of SARS-CoV-2. During clinical surveillance (median follow-up 113 days [IQR=90,146]), there was one (0.03%) adverse cardiac event likely unrelated to SARS-CoV-2 infection. Conclusions: SARS-CoV-2 infection among young competitive athletes is associated with a low prevalence of cardiac involvement and a low risk of clinical events in short term follow-up.

Project description:ImportanceMyocarditis is a leading cause of sudden death in competitive athletes. Myocardial inflammation is known to occur with SARS-CoV-2. Different screening approaches for detection of myocarditis have been reported. The Big Ten Conference requires comprehensive cardiac testing including cardiac magnetic resonance (CMR) imaging for all athletes with COVID-19, allowing comparison of screening approaches.ObjectiveTo determine the prevalence of myocarditis in athletes with COVID-19 and compare screening strategies for safe return to play.Design, setting, and participantsBig Ten COVID-19 Cardiac Registry principal investigators were surveyed for aggregate observational data from March 1, 2020, through December 15, 2020, on athletes with COVID-19. For athletes with myocarditis, presence of cardiac symptoms and details of cardiac testing were recorded. Myocarditis was categorized as clinical or subclinical based on the presence of cardiac symptoms and CMR findings. Subclinical myocarditis classified as probable or possible myocarditis based on other testing abnormalities. Myocarditis prevalence across universities was determined. The utility of different screening strategies was evaluated.ExposuresSARS-CoV-2 by polymerase chain reaction testing.Main outcome and measureMyocarditis via cardiovascular diagnostic testing.ResultsRepresenting 13 universities, cardiovascular testing was performed in 1597 athletes (964 men [60.4%]). Thirty-seven (including 27 men) were diagnosed with COVID-19 myocarditis (overall 2.3%; range per program, 0%-7.6%); 9 had clinical myocarditis and 28 had subclinical myocarditis. If cardiac testing was based on cardiac symptoms alone, only 5 athletes would have been detected (detected prevalence, 0.31%). Cardiac magnetic resonance imaging for all athletes yielded a 7.4-fold increase in detection of myocarditis (clinical and subclinical). Follow-up CMR imaging performed in 27 (73.0%) demonstrated resolution of T2 elevation in all (100%) and late gadolinium enhancement in 11 (40.7%).Conclusions and relevanceIn this cohort study of 1597 US competitive athletes with CMR screening after COVID-19 infection, 37 athletes (2.3%) were diagnosed with clinical and subclinical myocarditis. Variability was observed in prevalence across universities, and testing protocols were closely tied to the detection of myocarditis. Variable ascertainment and unknown implications of CMR findings underscore the need for standardized timing and interpretation of cardiac testing. These unique CMR imaging data provide a more complete understanding of the prevalence of clinical and subclinical myocarditis in college athletes after COVID-19 infection. The role of CMR in routine screening for athletes safe return to play should be explored further.
