Coronary artery bypass surgery. A community hospital's experience

The initial phase (1982) of a comprehensive surgical audit at a large community hospital involved 325 consecutive patients undergoing coronary artery bypass surgery. The resulting data were compatible with the findings of the Coronary Artery Surgery Study. Mean patient age was 57.5 +/- 8.8 years. Revascularization was complete in 77% of patients. Perioperative infarction rate was 4.6%, and in-hospital mortality was 1.2%. Operative risk was highest in those with left main coronary artery stenosis greater than 70%. Age, sex, and ventricular function status did not adversely affect survival.
