RESUMO
OBJECTIVE: To evaluate the necessity of cardiac testing after a COVID-19 diagnosis as it relates to myocarditis in collegiate athletes. DESIGN: Cross-sectional retrospective case series. SETTING: National Collegiate Athletic Association Division I University. PATIENTS: One hundred sixty-five collegiate athletes diagnosed with COVID-19 by reverse transcriptase-polymerase chain reaction or immunoglobulin G antibody between August and December 2020 without exclusion. INTERVENTIONS: All participants underwent cardiac workup consisting of serum troponin, electrocardiogram, transthoracic echocardiogram, and cardiac magnetic resonance (CMR). All results were reviewed by team physicians and sports cardiologists. MAIN OUTCOME MEASURES: Prevalence of myocarditis and abnormality on cardiac testing after COVID-19 infection at a single institution. RESULTS: One (0.61% [95% CI, 0.02%-3.3%] asymptomatic athlete had CMR findings of an age-indeterminate myocardial injury with further cardiac testing being otherwise normal. No athlete had CMR abnormalities consistent with acute myocarditis by the modified Lake Louise Criteria. CONCLUSIONS: Occurrence of myocarditis was lower in this population compared with other studies. No student athlete was permanently disqualified from participation because of testing. A stratified, risk-based testing strategy with CMR may be more appropriate than a universal screening strategy.
