Myocardial ischemia occurs when blood flow to your heart muscle is decreased by a partial or complete blockage of your heart's arteries (coronary arteries). The decrease in blood flow reduces your heart's oxygen supply. Myocardial ischemia, also called cardiac ischemia, can damage your heart muscle, reducing its ability to pump efficiently. A sudden, severe blockage of a coronary artery may lead to a heart attack. Myocardial ischemia may also cause serious abnormal heart rhythms.
