Myocarditis is an inflammation of the muscle of your heart (myocardium). The myocardium pumps blood through the heart and to other parts of the body. With myocarditis, the heart muscle can become damaged. This weakens the heart and makes it work harder. Over time, this may cause your heart to enlarge, lead to heart failure, and become life-threatening.
