Dödligt virus från Kina orsakar panik (SARS-CoV-2, COVID-19)

We performed CMR imaging in 26 competitive college athletes (mean [SD] age, 19.5 [1.5] years; 15 male [57.7%]) from the following sports: football, soccer, lacrosse, basketball, and track. No athletes required hospitalization or received COVID-19–specific antiviral therapy. Twelve athletes (26.9%; including 7 female individuals) reported mild symptoms during the short-term infection (sore throat, shortness of breath, myalgias, fever), while others were asymptomatic. There were no diagnostic ST/T wave changes on electrocardiogram, and ventricular volumes and function were within the normal range in all athletes by transthoracic echocardiogram and CMR imaging. No athlete had elevated serum levels of troponin I. Four athletes (15%; all male individuals) had CMR findings consistent with myocarditis based on the presence of 2 main features of the updated Lake Louise Criteria: myocardial edema by elevated T2 signal and myocardial injury by presence of nonischemic LGE (Figure).4 Pericardial effusion was present in 2 athletes with CMR evidence of myocarditis. Two of these 4 athletes with evidence of myocardial inflammation had mild symptoms (shortness of breath), while the other 2 were asymptomatic. Twelve athletes (46%) had LGE (mean of 2 American Heart Association segments), of whom 8 (30.8%) had LGE without concomitant T2 elevation (Table). Mean (SD) T2 in those with suspected myocarditis was 59 (3) milliseconds compared with 51 (2) milliseconds in those without CMR evidence of myocarditis.
