Myocarditis is a form of heart disease that results from inflammation of the muscles that comprise the heart. This inflammation can weaken your heart making it harder to pump blood to the rest of your body. Myocarditis may result in feeling shortness of breath, faster or irregular heartbeat, and chest pain. An episode of myocarditis may resolve completely or may cause long-lasting harm. The most common cause of myocarditis is a viral infection, but other types of infection can cause myocarditis. Certain chemicals have also been known to cause myocarditis.
