The conditions described by the term ACS exist along a spectrum of severity and include ST elevation myocardial infarction (STEMI), non-ST elevation MI (NSTEMI), and unstable angina (UA). The most common etiology of ACS in the nonsurgical setting is atherosclerotic plaque rupture on the wall of a coronary artery, causing partial or complete obstruction of the artery.
