Abstract:
Objective To evaluate the appropriate timing of coronary artery bypass grafting(CABG) with acute myocardial in- farction(AMI) and to discuss the influence of postoperative mortality on 30 days.Methods 233 patients after CABG were divided into 2 groups,AM/group and unstable angina (UA) group.There were 176 males (75.4%) and 57 females (24.5%).The mean age was (65.6?9.2) years(range 34～86 years).The mean grafts were 3.46?0.89.The complex risk elements between the 2 groups were analyzed to evaluate the independent risk element of death.Results Internal mammary arteries were used in 137 patients (58.8%).The postoperative mortality rate was 4.3 % (10/233).The operative mortality rates(OMR) were closely related to the in- creasing time intervals between AMI and CABG,for less than 3 days was 14.6% (6/41 cases),for 4 to 10 days was 2.7 % (1/37) and for 11 to 30 days was 0.The OMR of AMI less than 3 days has significant difference (P=0.033) comparing with that of unstable an- gina pectoris [2.3% (3/130) ].Conclusion Proper timing of CABG should be done in 3 days after AMI.
