Missing cases: lesions ≥50% stenosis (n = 3); 1 or more 100% lesions (n = 3); percentage myocardium jeopardized (n = 4); lipid-lowering drug (n = 2); history of myocardial infarction (MI) (n = 18); history of congestive heart failure (CHF) (n = 10); vessel disease (n = 3); ejection fraction (n = 475).

BARI = Bypass Angioplasty Revascularization Investigation; CABG = coronary artery bypass graft surgery; PCI = percutaneous coronary intervention.

  • * Canadian Heart Classification, (CHC) 3, 4, or unstable angina.
