| ABSTRACT Fifty patients with electrocardiographic (ECG) evidence of left Bundle Branch Block (LBBB) and fifty control group with no significant electrocardiographic findings were studied over the period from October 2004 to July 2005 for evidence of Coronary Artery Disease (CAD) and Left Ventricular (LV) dysfunction. Both groups underwent cardiac catheterization and CAD considered present if there was 70% and more lumen diameter stenosis except for Left Main Coronary Artery (LMCA) was 50% and more. LV function was assessed visually and the function was considered normal or abnormal. The CAD was found in 37/50 (74%) of patients with LBBB, it was significantly (P<0.002) higher than in control group 14/50 (28%), the percentage of LAD artery disease was significantly (P<0.001) higher in patients with LBBB 36/50 (72%) than in control 5/50 (10%) and LV dysfunction was present in 30/ 50 (60%) of patients with LBBB it was significantly (P< 0.001) higher than in control 9/50 (18%) In conclusion: the study showed that the patients with LBBB had higher incidence of CAD and LV dysfunction | ||
