Abstract

INTRODUCTION: The aim of coronary artery bypass graft surgery is to relieve angina, protect from late myocardial infarction and possibly prolong survivail1,2,3,4) In Pakistan, this operation is still. in its evolutionary stage. It has been thought that Asian patients have smaller caliber and more diffusely diseased coronary arteries which may produce less satisfactory results after surgery than in the western patients. The purpose of this paper is to analyze the early and medium term results of myocardial revascularization at AFIC Rawalpindi. PATIENTS AND METHODS: Between December 1981 and May 1985, 106 patients underwent coronary artery bypass graft surgery at AFIC Rawalpindi. There were 104 males and 2 females ranging in age between 33 and 65 years (mean 49 years). The age distribution is shown in Table-I. The majority were between 41 and 60 years of age. DISCUSSION: It is widely accepted that the aims of corona ry artery bypass graft surgery include relief of angina, protection from late myocardial infarction and possibly improved surviva12’3’4 However, preoperative myocardial infarction may Occur in 5 20% of the cases5’6’ late myocardial infarction may occur in• up to 10% of cases, and complete or partial relief of symptoms may be obtained in up to 90% of patients at 5 years.
