And, although the organization's purpose is to support the interests of the United States, the Green Berets exist in the haze that floats between the country and other nations, groups and peoples -- they're the nimble fingertips of the United States military and the quiet professionals of the U.S. government.
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.
The more severe type of heart attack is called an ST-segment-elevation myocardial infarction, or STEMI. In a STEMI, the coronary artery is completely blocked by a blood clot, so all of the heart muscle that usually receives blood from the affected artery will begin to die.
