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.
