Because the ST segment on the ECG does not become elevated in this condition, it is called a non-ST-segment elevation myocardial infarction, or NSTEMI. When the blood clot that forms during ACS completely blocks the artery, all the heart muscle supplied by the artery begins to die.
NSTEMI refers to non-ST elevation myocardial infarction. That is, parts of the heart muscle is infarcting without any ST elevations on the 12 lead EKG. Usually evidence of a NSTEMI is determined based on serial troponins (a cardiac enzyme). If there is any measurable amount of troponin in the blood, then heart muscle damage, of some sort, has occurred. In the absence of some other cause (PE, for instance, can cause a troponin elevation), NSTEMI is diagnosed.
