Study in JAMA finds post-vaccination myocarditis has fewer adverse cardiovascular events than conventional myocarditis.

A study published in JAMA found that post-vaccination myocarditis, or inflammation of the heart muscle, resulted in fewer adverse cardiovascular events than conventional myocarditis. Researchers analyzed 4,635 patients aged 12 to 49 hospitalized for myocarditis from December 2020 to June 2022. Participants were divided into three groups: those with vaccine-related myocarditis, infection-related myocarditis, or myocarditis for other reasons. The study suggests that the risk of myocarditis linked to mRNA vaccines is low and that COVID-19's impact on the heart is not limited to myocarditis.
