A majority of people affected by heart conditions such as myocarditis after receiving COVID-19 shots were still suffering from the symptoms six months after the illnesses were diagnosed, according to a recent Australian study.
The peer-reviewed study, published in the journal Vaccine on Dec. 27, looked at two adverse events of special interest (AESI) post COVID-19 vaccination: myocarditis and myopericarditis. Myocarditis refers to the inflammation of a heart muscle called the myocardium, while myopericarditis is a condition in which the myocardium and the pericardium—the heart’s protective sac—are inflamed.
