Abstract: Background & Objective Left bundle branch (LBBB) is common ECG finding. Common causes of LBBB are coronary artery disease (CAD), dilated cardiomyopathy (DCM) and hypertension. The objectives of this study were to determine presenting symptoms, risk factors, echocardiography and angiographic findings in patients with Left bundle branch block (LBBB), who underwent coronary angiography in Rajarajeshwari Medical college and hospital (cardiology dept. ). Material and methods All patients with symptomatic complete LBBB who attended OPD/IPD from July 15, 2014 to January 20, 2017 were included. Demographic profile such as age and sex, presenting symptoms, risk factors, echocardiography and coronary angiographic findings were studied. The study included 85 patients, 46 patients (54.1 %) were males and 39 patients (45.9 %) were females with a mean age of 58 years. Male patients with LBBB have more incidences of both abnormal coronary angiography (70 %) and three vessels disease (72 %) than female patients. In our study 64 % of patients with LBBB had hypertension. Patients with 2 or more risk factors showed a higher percentage (46 %) of having abnormal angiography. Based on echocardiography findings, RWMA constitutes the major finding (27, 31.78 %). In the patients with CAD, there were normal ejection fraction (EF) in 8 patients (26 %) and depressed EF in 22 patients (74 %). In conclusion, hypertension was a major risk factor for LBBB. Left anterior descending artery (LAD) artery was the most common vessel disease. . Conclusion Patients with LBBB on ECG referred for coronary angiography represent a very small Minority of all cardiac catheterization patients. HTN was the commonest cardiovascular risk factor. Males show an overall higher degree of affection than females in regards with three vessels disease. Patients who had 2 or more risk factors had a higher percentage of having abnormal angiography. Left ventricular EF was lower in LBBB patients who had CAD.
