COVID-19 linked to heart damage in healthy people, small study suggests


People who recover from COVID-19 may have lingering heart damage and inflammation months after their initial infection, even if they were not hospitalized, a small new study suggests.

The study, published Monday (July 27) in the journal JAMA Cardiology, involved 100 adults ages 45 to 53 in Germany who had recently recovered from COVID-19. About one-third of participants required hospitalization while the other two thirds were able to recover at home. On MRI scans taken more than two months after their diagnosis, about three-quarters of these patients showed signs of heart abnormalities, including inflammation of the heart muscle, or myocarditis. Many patients also had detectable levels of a protein in their blood called troponin that can indicate heart injury, such as damage after a heart attack. (Troponin is a protein found in heart cells that is released into the blood when the heart muscle is damaged, according to the University of Rochester Medical Center.)
