Encouraging news emerged from a COVID-19 cardiac study of professional athletes published in "JAMA Cardiology" on Thursday.

Of the 789 professional athletes from the NBA, WNBA, NFL, NHL, MLB and MLS who tested positive for coronavirus and underwent cardiac screening, just 30 were sent for additional testing and just five were diagnosed with inflammatory heart disease – three with myocarditis and two with pericarditis, according to the study.

As a precaution, the major North American pro sports leagues implemented cardiac screening as part of the return to play protocols for athletes who had the virus.
