Angina: Symptoms relieved by NG; MI not relieved by NG
stable: unruptured plaque, blocking blood flow. RBC squeeze through. Symptoms with exertion. May have ST depression during symptoms
unstable angina: ruptured plaque, clot, subendothelial (ST depression) ischemia (no markers)
prinzmetal: transmural (ST elevation) ischemia (no markers)
NSTEMI: subendothelial necrosis, clot not completely obstruct artery (not transmural yet)
STEMI: transmural necrosis, clot completely obstructs artery, transmural
