Abstract:
To study the cause of postoperative complications of coronary artery bypass grafting(CABG) and their preventive measures. 210 cases were reviewed and analyzed from 1993 to 2000, including 194 males and 16 females with a mean age of 58 7 years (range 32～78 years). 150 patients had three coronary vessels disease 101 patients had the history of myocardial infarction 33 patients were in heart function Ⅲ～Ⅳ(NYHA) CABG under cardiopulmonary bypass(CPB) were performed in 200 cases, and off-pump CABG in 10 cases The average number of grafts were 3 1. Cardiac valve replacement and plastic operation were done in 25 patients at the same time, and left ventricular aneurysms were resected in 8 cases The hospital mortality was 1 9%(4/210), and 13 patients had perioperative myocardial infarction. The recurrence rate of angina was 5 2%(11/210). The incidence of postoperative arrhythmia was 16 2%(34/210). A rise of creatine kinase level was observed in 145 cases after CABG. Incidence of painless myocardial infarction was very high(11/13) in perioperative myocardial infarction, therefore the level of myocardial enzymes should be assessed after the operation and the changes in electrocardiogram should be monitored in order to avoid misdiagnosis. The great majority of postoperative arrhythmias were atrial flutter,atrial fibrillation, and supraventricular tachycardia. Normal sinus rhythm was readily restored by conventional treatment.
