Abstract

Background and objective: The goal of this study was to determine the association of complete left bundle branch block (LBBB), site , severity & risk factors of coronary artery disease (CAD). Complete Left bundle branch block increases the risk of cardiac mortality, and prognosis is primarily determined by the underlying CAD. Because the presence of complete LBBB makes the noninvasive identification of CAD less informative, patients with complete LBBB often are referred for coronary angiography to assess the presence and severity of CAD. Methods: A total of 150 consecutive patients with complete LBBB admitted to the coronary care unit were enrolled from the age of 27 to 81 years with the mean age of 59.32 ± 10.5. Male 84 (56%), Female (44%). History, basal investigations echocardiography and virology screen were performed. Coronary angiography has been done for all patients for different reasons of presentation. Results: Critical CAD 70 (46.7%), Left ventricular systolic dysfunction (LVSD) 50 (33.3%). Hypertension found in 83 (55.3%), diabetes mellitus (DM) in 44 (30%), DM& left ventricular systolic dysfunction(LVSD) were more associated with critical CAD. Conclusion: In our study complete LBBB was more common among hypertensive patients. In DM patients was associated with severe CAD. With Left anterior descending artery being the most common artery involved.
