Athletes with mild COVID-19 illness demonstrate subtle imaging abnormalities without exercise impairment or arrhythmias

Coronavirus disease-19 (COVID-19) has been associated with cardiac pathology raising the possibility of serious cardiac arrhythmias among athletes returning to competition post infection. Several studies have assessed cardiac function and structure in athletes post-COVID-19 infection but have been challenged by selection bias, lack of an appropriate control group and none have included comprehensive imaging, exercise testing, and clinical electrophysiology.
