AbstractThe incidence of post-COVID-19 cardiac compromise is not well known. The eventual cardiac repercussions on a return to high-performance sport are unclear. A prospective observational study with evaluation by physical examination, electrocardiogram, Doppler echocardiogram and cardiac magnetic resonance imaging (CMR) was carried out in international level professional soccer players recovering from COVID-19 who had the disease asymptomatic or with mild symptoms. Four-month follow-up with participation in national and international competitions. Twenty-four soccer players were included, age 27.13 years (between 20 and 36). Nine (37.5%) had asymptomatic disease and 15 (62.5%) had mild symptoms. No athletes required hospitalization. Physical, electrocardiographic, and echocardiographic examinations did not reveal heart disease. CMRs showed ventricular thicknesses and volumes consistent with high-performance athletes. In T1, T2 and fat saturation signals, no fat infiltration or signs of edema were observed. No late enhancement after gadolinium injection. They began their training between 12 and 14 days after diagnosis. Eleven (45.8%) participated between 4 and 6 international matches of Libertadores de América International Cup. The remaining 13 completed high intensity training sessions and participated in local league competitions. At 4 months after diagnosis, none of the soccer players developed cardiac events and training and competitions were well tolerated. These findings suggest low cardiovascular impact of COVID 19 and excellent tolerance to early post-COVID high intensity exercise of young athletes recovering from the disease with no or mild symptoms.
