SARS-CoV-2 cardiac involvement low in collegiate athletes

(HealthDay)—For U.S. collegiate athletes, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is associated with a low prevalence of cardiac involvement, according to a study published online April 17 in Circulation.

Nathaniel Moulson, M.D., from Massachusetts General Hospital in Boston, and colleagues conducted a prospective, multicenter, observational cohort study to examine the prevalence, clinical characteristics, and outcomes of SARS-CoV-2 cardiac involvement among U.S. collegiate athletes from Sept. 1 to Dec. 31, 2020.

The researchers found that 3,018 of the 19,378 athletes tested positive for SARS-CoV-2 and underwent cardiac evaluation. Overall, 2,820 athletes underwent at least one element of cardiac triad testing (12-lead electrocardiography [ECG], troponin, and/or transthoracic echocardiography [TTE]); if clinically indicated, this testing was followed by cardiac magnetic resonance (CMR). Primary screening CMR was conducted in 198 athletes. Abnormal findings indicative of SARS-CoV-2 cardiac involvement were identified by ECG, cardiac troponin, and TTE in 0.7, 0.9, and 0.9 percent, respectively. In 21 athletes (0.7 percent), definite, probable, or possible SARS-CoV-2 involvement was identified; of these athletes, 0.5 percent underwent clinically indicated CMR and 3.0 percent underwent primary screening CMR (15 and six, respectively). Compared with a primary screening CMR, the diagnostic yield of CMR for SARS-CoV-2 involvement was 4.2 times higher for a clinically indicated CMR (12.6 versus 3.0 percent).

"Most athletes with no symptoms or mild illness from SARS-CoV-2 can return to sports safely without additional cardiac testing as long as they feel good on return to exercise and don't have cardiopulmonary symptoms like chest pain," a coauthor said in a statement.
