ST Segment Elevation Myocardial Infarction (STEMI) is the name cardiologists currently use to describe a classic heart attack. âMyocardial infarction,â or heart attack, refers to the death of a portion of the heart muscle (myocardium) caused by blood flow interruption. âST segment elevationâ refers to a particular pattern seen on the electrocardiogram (ECG), often seen when a substantial part of the heart muscle is dying.
More than a million Americans have heart attacks each year. A heart attack, or myocardial infarction (MI), is permanent damage to the heart muscle. Myo means muscle, cardial refers to the heart, and infarction means death of tissue due to lack of blood supply.
