New return-to-play updated guidance for athletes after COVID 19 infection

USA: A group of sports cardiologists have released an updated guideline for athletes returning to play (RTP) after COVID-19 infection. The guideline, published in the journal JAMA Cardiology, recommends a risk stratification approach, with screening for cardiac injury only for athletes with severe disease or preexisting cardiovascular (CV) conditions. 

The prevalence of cardiac pathology in infected athletes is not fully understood, but publicized reports of athletes with suspected COVID-19–induced myocarditis and studies showing myocardial injury in individuals even with mild or asymptomatic infection have generated concern about how to safely manage COVID-19 in athletes.

In May, the American College of Cardiology issued RTP recommendations after data emerged showing cardiac injury in COVID-19–hospitalized patients, including myocardial inflammation and myocarditis. Those recommendations directed asymptomatic athletes to restrict activity for 2 weeks from the date of a positive test result, followed by slow resumption of activity and risk stratification testing—electrocardiogram, echocardiogram, troponin testing, cardiac magnetic resonance (CMR) imaging—only if symptoms of cardiac involvement occurred. Symptomatic athletes were advised to refrain from exercise for 2 weeks following symptom resolution, followed by CV evaluation using biomarkers and imaging, and cardiac magnetic resonance (CMR) imaging if indicated.
