Implication
May aid risk stratification for CABG in unstable angina; leaves open whether modifying predictors improves outcomes.

Population
6,539 patients undergoing surgical revascularization for unstable angina, mean age 58.9 years, male:female ratio 3.6:1.

Intervention
Surgical revascularization (coronary bypass)
O
Outcome
Operative mortalityhard clinical
Urgent surgery, depressed left ventricular function, and preoperative myocardial infarction are major independent predictors of operative mortality in patients undergoing coronary bypass for unstable angina.
