Abstract:
From July 1994 to August 1995, 32 patients underwent coronary artery bypass surgery. There were 14 men and 18 women. The mean age was 59 years(range from 37 to 81 years). Preoperatively 26 patients had unstable angina pectoris and 6 patients had stable angina pectoris. Nine patients had previous myocardial infarction history. Five patients had preoperative left ventricular ejection fraction of 40% or less. The involved risk factors were as follows ; smoking 19 cases, hypertension 16 cases, hypercholesterolemia 14 cases, diabetes mellitus 6 cases, and obesity 3 cases. 21 patients had three-vessel disease, 7 patients had two-vessel disease, 2 patients had one-vessel disease and 2 patients had left main coronary artery disease. We performed 103 distal bypasses out of 32 cases, and the mean number of grafts per patients is 3.22. We used arterial grafts (left internal mammary artery ; 31, radial artery ; 2) in 32% of total grafts. Postoperative complications were low cardiac output, perioperative myocardial infarction, respiratory failure and atrial fibrillation, etc. Early mortality was 6.25% (2/32). The causes of deaths were low cardiac output (1), and perioperative myocardial infarction(1).
