ABSTRACT
To see the frequency of coronary artery stenosis in the patients of stable angina having left bundle branch block, and to see the effects of gender and age on this correlation. Experimental case series. Bahawal Victoria Hospital, Bahawalpur. June 2006 to May 2008. One hundred and forty one [141] patients of Stable Angina presenting with atypical chest pain, both male and female of 30-70 years age, positive for LBBB and with normal Cardio-Thoracic Ratio, normal echocardiography and negative for conventional risk factors and family history of Coronary Artery Disease were taken. All patients were angiographied. A total of 141 patients were investigated through coronary angiogram to see the frequency of coronary artery stenosis in these patients. Ninety five [67.4%] patients proved to have coronary artery stenosis. The male patients showed higher frequency [87.4%] of harboring coronary vessel blockade as compared to that [35.2%] in females [P value <0.0005]. There was no relation between age and the frequency of coronary stenosis [P value > 0.05]. There is significant difference [P value < 0.0005] in coronary artery stenosis among men and women having LBBB
