Myocardial infarction, commonly known as a heart attack, occurs when the coronary arteries become blocked, cutting off the blood supply to parts of the heart muscle. This lack of oxygenated blood causes tissues in the myocardial muscles of the heart to die. A myocardial infarction is also referred to as a heart attack and results from prolonged lack of oxygen to the heart muscle cells.
