Objectives We sought to explore the spectrum of cardiac abnormalities in student-athletes who returned to university campus in July 2020 with an uncomplicated Coronavirus disease 2019 (COVID-19). Background There is limited information regarding cardiovascular involvement in young individuals with mild or asymptomatic COVID-19. Methods Screening echocardiograms were performed in 54 consecutive student-athletes (mean age: 19 years, 85% males) who tested positive on reverse transcription–polymerase chain reaction nasal swab testing of the upper respiratory tract or IgG antibodies against SARS-CoV-2. A sequential cardiac magnetic resonance (CMR) imaging was performed in 48 (89%) subjects. Results A total of 16 (30%) athletes were asymptomatic while 36 (66%) and 2 (4%) reported mild and moderate COVID-19 related symptoms, respectively. For the 48 athletes completing both imaging studies, abnormal findings were identified in 27 (56.3%) individuals. This included 19 (39.5%) showing pericardial late enhancements with associated pericardial effusion. Of the individuals with pericardial enhancements, 6 (12.5%) had reduced global longitudinal strain (GLS) and/or an increased native T1. One patient showed myocardial enhancement and reduced left ventricular ejection fraction or reduced GLS with or without increased native T1 were also identified in additional 7 (14.6%) individuals. Native T2 were normal in all subjects and no specific imaging features of myocardial inflammation were identified. Hierarchical clustering of LV regional strain identified three unique myopericardial phenotypes that showed significant association with the CMR findings (P=0.03). Conclusion Over one in three previously healthy college-athletes recovering from COVID-19 infection showed imaging features of a resolving pericardial inflammation. Although subtle changes in myocardial structure and function were identified, no athlete showed specific imaging features to suggest an ongoing myocarditis. Further studies are needed to understand the clinical implications and long-term evolution of these abnormalities in uncomplicated COVID-19.
