There are three main types of heart inflammation: endocarditis, myocarditis, and pericarditis. Endocarditis is inflammation of the inner lining of the heart’s chambers and valves. Myocarditis is inflammation of the heart muscle. Pericarditis is inflammation of the tissue that forms a sac around the heart. Many things cause heart inflammation. Common causes include viral or bacterial infections and medical conditions that damage the heart and cause inflammation.
You may have different signs and symptoms depending on the type and severity of the heart inflammation that you have. The treatment your doctor recommends may depend on whether you are diagnosed with inflammation of the lining of your heart or valves, the heart muscle, or the tissue surrounding the heart. You may be treated with medicine, procedures, or possibly surgery to treat your condition and its complications. Complications may include an arrhythmia, or irregular heartbeat, and heart failure.
