Preoperative anamnestic information indicating depressed myocardial function or severe ischemia were more important predictors of death and cardiac events at 2 years than cardioangiography.
Cohort (n=1,841)
Clinical history indicating depressed myocardial function or severe ischemia prior to CABG are important predictors of adverse outcomes within 2 years post-surgery.
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. CONCLUSION: 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.
Herlitz et al. (Thu,) conducted a cohort in Coronary artery bypass grafting (CABG) (n=1,841). Preoperative risk indicators (e.g., congestive heart failure, diabetes, renal dysfunction) was evaluated on Death and other cardiac events. Preoperative anamnestic information indicating depressed myocardial function or severe ischemia were more important predictors of death and cardiac events at 2 years than cardioangiography.
