GENERAL PRINCIPLES

Definition

• Acute coronary syndrome (ACS) refers to any constellation of clinical symptoms that are compatible with acute myocardial ischemia. For simplicity, ACS can be divided into STEMI, NSTEMI, and UA.
• STEMI results from complete and prolonged occlusion of an epicardial coronary blood vessel and is defined based on ECG criteria (ST-segment elevation greater than 0.1 mV in at least two contiguous leads or a new LBBB).
