Background & objective: Left bundle branch block (LBBB), resulting in an alteration of the normal sequence of activation in the left ventricle, commonly occurs in patients with underlying heart disease particularly coronary artery disease (CAD), but it may also be associated with progressive conducting system disease in an otherwise structurally normal heart. The aim of this study was to evaluate the clinical and angiographic profile of patients presenting with LBBB. Materials & Methods: This study was a cross-sectional observational study. A total of 542 patients of LBBB (as evident by ECG) who underwent coronary angiography from 1st September 2005 to 31st August 2016 were identified from the records of Cath Lab database of Ibrahim Cardiac Hospital & Research Institute and were selected for the study. LBBB was defined as a QRS complex duration ≥120 ms with a broad notched or slurred R wave in leads I, aVL, V5 and V6. Results: Majority (95.8%) of the patients was over 40 years of age with mean age being 59.7 ± 10.7 years (range: 25-95 years). Nearly 60% of the patients were male, 62.2% diabetic and 69.7% hypertensive. Over one-third (37.1%) of patients had moderate left ventricular (LV) systolic dysfunction (ejection fraction 30-44%) and 7% had severe LV systolic dysfunction. Over half (51.9%) had normal body mass index. Unstable angina (45.8%) was the most common indication for angiography. Other indications included non-ST segment elevation myocardial infarction (17.2%), ST segment elevation myocardial infarction (11.3%), stable coronary artery disease (SCAD) (9.8%), prior myocardial infarction (13.3%) and atypical chest pain (2.6%). Nearly 60% of the patients had obstructive coronary artery disease and the rest (40.6%) had normal epicardial coronaries on angiography. Among those with obstructive CAD, 4.1% had left main disease, 20.5% had triple vessel disease (TVD), 14.4% double vessel disease (DVD) and 9.5% single vessel disease (SVD). Conclusion: There is an optimum prevalence of CAD among LBBB patients, with TVD being predominant. LBBB cases with normal coronaries are no less. The latter cases suggest an alternative cause for LBBB. Thus, the usual diagnosis of CAD in patients with presumably new onset LBBB may be over-estimated in clinical practice.

Background: Coronary artery disease is the leading cause of death in the world. Advancing age is a well-recognized risk factor for acute myocardial infarction (AMI). Myocardial infarction is less common in young adults. Prevalence of acute coronary syndrome in young individuals is increasing progressively. These patients have different risk profile, presentation and prognosis. Early recognition and risk factor modification in this population sub-set is of key importance. Objectives: The purpose of the present study was to determine the differences in risk factors and coronary angiographic profile of young patients with ST-segment elevated myocardial infarction (STEMI) vs. those with non-ST-segment elevated myocardial infarction (NSTEMI). Methods: In this cross sectional analytical study total 135 patients (70 STEMI and 65 NSTEMI) aged ≤45 years were enrolled to see the differences of risk factors and angiographic profile. Results: The mean age of the study population was 39.39±5.12 years and the study showed male predominance (90.40 % was male and 9.60 % was female). Smoking/tobacco consumption was significantly higher in STEMI patients, whereas diabetes mellitus and hypertension were more prevalent in NSTEMI patients. The frequency of single vessel disease and involvement of left anterior descending artery was significantly higher in young STEMI patients. In case of young NSTEMI patients frequency of triple vessel disease, noncritical coronary artery disease and involvement of left circumflex coronary was significantly higher. The frequency of double vessel disease and involvement of left main coronary artery was also nonsignificantly higher in young NSTEMI patients. There was no significant difference regarding involvement of right coronary artery. Conclusion: There are significant differences between young STEMI and young NSTEMI patients in respect to risk factors and angiographic profile. Key words: Young patient, STEMI, NSTEMI, Risk factors, Coronary angiographic profile. Bangladesh Heart Journal 2021; 36(2): 124-132
