Predictors of death and other cardiac events within 2 years after coronary artery bypass grafting.
RESULTS
In 1,841 patients who underwent coronary artery bypass grafting (CABG) we evaluated risk indicators for death and other cardiac events during 2 years of follow-up. Independent predictors of death were: a history of congestive heart failure, diabetes mellitus and renal dysfunction prior to CABG. Independent predictors of death, acute myocardial infarction (AMI), CABG or percutaneous transluminal coronary angioplasty (PTCA) were: a small body surface area, a history of congestive heart failure, diabetes mellitus and smoking prior to CABG. Independent predictors of death, AMI, CABG, PTCA or rehospitalization for a cardiac reason were: angina functional class, previous AMI, a history of congestive heart failure and renal dysfunction prior to CABG.


CONCLUSIONS
When using various definitions of a cardiac event after CABG, various risk indicators for death or such an event can be found. Our data suggest that anamnestic information prior to CABG indicating a depressed myocardial function or severe myocardial ischemia are more important predictors of outcome than the information gained from cardioangiography.
