Type 1: Plaque rupture event with coronary occlusion (common cause of STEMI)
Type 2: Supply demand mismatch, where physiologic stress (e.g. sepsis, tachycardia, anemia, hypoxemia, etc) causes increased myocardial O2 demand that can't be met; can be superimposed on pre-existing CAD
Type 3: Sudden cardiac death related to MI
Type 4: MI during percutaneous procedure
Type 5: MI during by-pass surgery
