Journal Title: PARIPEX-Indian Journal of Research - Year 2019, Vol 8, Issue 6
Abstract
INTRODUCTION: Left main coronary artery (LMCA) stenosis carries high mortality and morbidity in the absence of revascularization. So, the anatomy and the site of stenosis in the left main coronary artery determine the management option. MATERIAL &METHODS: 2000 cases of symptomatic coronary artery disease, who underwent coronary angiography at Rajiv Gandhi government hospital and madras medical college, Chennai over a period of one year from march 2018- february 2019 were studied and their coronary angiograms were analysed with respect to the pattern of involvement. RESULTS: Of the 2000 cases of coronary artery disease, 90 patients have significant left main coronary artery disease. 6th decade is common age group of presentation. Male 72%, female 28%. Of them 57.6% are hypertensive, 64.5 % are diabetics, 36% are smokers.29% present as STEMI ,43% as NSTEMI/UA , 28% as CSA. Isolated LMCA involvement is seen in 3 cases, associated with single vessel disease in 8, double vessel disease in 28 and triple vessel diseases in 51. Ostio proximal involvement is seen in 15, mid shaft involvement in 7, distal bifurcation involvement in 51, distal shaft without ostium in 6, diffuse involvement in 11 cases. CONCLUSION: Significant LMCA involvement is seen in 4.5%. distal bifurcation is the commonest site involved. In majority of cases, it is associated with triple vessel disease
