Values are expressed as % or mean ± SD.

 BMS = bare-metal stent(s); CABG = coronary artery bypass graft; DES = drug-eluting stent(s); LAD = left anterior descending artery; LCX = left circumflex artery; LM = left main; MI = myocardial infarction; PCI = percutaneous coronary intervention; RCA = right coronary artery; SA = stable angina; UA = unstable angina.
