  1. *Ischemic time: defined as the time difference between beginning of the chest pain and artery opening.
  2. Multivessel disease: defined as significant coronary artery disease (>50% diameter stenosis) in ≥ 2 major epicardial artery.
  3. Angiographic success: defined as <20% residual stenosis + TIMI 3 flow post-PCI.
  4. MR: Mitral Regurgitation; TIMI - Thrombolysis in myocardial infarction; CK-MB - Serum myocardial band of creatine kinase.
