Explanation: A heart attack occurs when blood flow to a part of your heart is blocked for a long enough time that part of the heart, muscle is damaged or dies. The medical term for this is myocardial infarction. Most heart attacks are caused by a blood clot that blocks one of the coronary arteries. The coronary arteries bring blood and oxygen to the heart.
