LOS ANGELES - In a study published in September, researchers from Ohio State University found that out of more than two dozen athletes from the university who tested positive for COVID-19, 30% had cellular heart damage and 15% showed signs of heart inflammation caused by a condition known as myocarditis.After mapping the hearts of 26 Ohio State University athletes using a process known as cardiac magnetic resonance (CMR), researchers found that not only 15% of students exhibited the rare heart condition but 30% showed cellular damage. "Cardiac magnetic resonance imaging has the potential to identify a high-risk cohort for adverse outcomes and may, importantly, risk-stratify athletes for safe participation," study authors wrote.
