Caption: COVID-19 vaccination activates the immune system to build protection against SARS-CoV-2. Researchers are studying why rare inflammatory reactions occur in a small subset of vaccinated individuals.
What Is Myocarditis?
nbsp;
Myocarditis is inflammation of the myocardium, the muscular tissue that makes up the heart.
The condition can interfere with the heart’s normal function because inflammation may affect the heart muscle’s ability to contract or disrupt its electrical activity. In severe cases, myocarditis can lead to abnormal heart rhythms or impaired heart function.
However, myocarditis is not exclusively associated with COVID-19 vaccination.
A wide variety of infections and medical conditions can cause inflammation of the heart. Viral infections are among the most recognized causes, and COVID-19 itself can affect the cardiovascular system.
This distinction is extremely important when evaluating reports of myocarditis following vaccination.
