Early reports on the effects of COVID-19 found that between 14% and 60% of people who recovered from the virus suffered long-lasting myocarditis (heart muscle inflammation). A recent study found that those rates could be wrong—myocarditis might actually be fairly rare, happening in only 1.4% of cases in athletes and 7.2% of cases in older, sicker people. Study results were published in the journal Cardiovascular Pathology.
Said coauthor Dr. Marc Halushka, a professor of pathology at Johns Hopkins University School of Medicine, Baltimore, Maryland:
“What we have learned is that myocarditis is not nearly as frequent in COVID-19 as has been thought. This finding should be useful for our clinical colleagues to reconsider how to interpret blood tests and heart radiology studies.”
The researchers studied autopsies from 9 countries of 277 people who died of COVID-19. Their report included a checklist for use in autopsies so that results found in COVID-19 patients could be recorded consistently.
According to Dr. Richard Vander Heide, professor of medicine at Louisiana State University Health Sciences Center, New Orleans, even a myocarditis rate as low as 1.4% in means that myocarditis could affect hundreds of thousands of COVID sufferers worldwide, because so many people are getting the virus.
