[Late cardiac events of coronary bypass surgery].
The cardiac events of 598 patients undergoing coronary bypass surgery were analyzed. The hospital and late death was 4.9% and 3.8%, respectively. The late death were caused by cardiac events in 7 patients and non-cardiac events in 16 patients. Of 7 cardiac death, 5 patients were died of acute myocardial infarction (AMI), and 2 patients were died of congestive heart failure. 5-year survival rate, 5-year event free ratio, and 5-year non-cardiac event free ratio were 88%, 70% and 91%, respectively. Of 18 patients who suffered from AMI after operation, 5 patients died. The causes of AMI were grafts occlusion in 9 patients, progression of coronary lesions in 5 patients and unknown in 4 patients. PTCR, PTCA and rebypass surgery were performed in 4, 9 and 8 patients, respectively.
