LEFT MAIN DISEASE — PATIENT PROFILE

Abstract

Background: Left main coronary artery (LMCA) disease is a potentially lethal disease that can be effectively treated if it is recognized early. The aim of our study was to define the demography of patients with left main disease among those undergoing angiography at our center. Methods: The profile of 180 patients, who were found to have left main disease out of a total of 1111 consecutive patients undergoing coronary angiography, was studied retrospectively. Obstructive left main disease was defined as ≥ 50% diameter stenosis on angiogram. All patients having atheromations involvement of left main coronary artery from plaques to total occlusion were included. Results: The overall incidence of left main disease was 16.2%, however, if only obtrusive lesion lesions were considered it was 4.5%. Mean age was 58.9 years. 41.6% (75) were smokers and 50% were hypertensive Diabetes is prevelant in the majority of these patient, being 67.2%, but the incidence of obstructive disease is not increased. Obstructive left main disease is seen in 34.7% among male smokers against 21.6% in non smokers. Conclusion: Left main disease appear to be related to increasing age. Diabetes is the commonest prevalent risk factor in this patient population. Among male smokers obstructive left main disease prevalence is higher then non smokers.
