BACKGROUNDLeft bundle branch block (LBBB) is a common ECG finding. Common causes of LBBB are coronary artery disease (CAD), dilated cardiomyopathy (DCM) and hypertension. The objective of this study was to correlate left ventricular function and aetiology in LBBB patients coming to our rural hospital.
MATERIALS AND METHODSThis is a descriptive study. All patients with complete LBBB who attended Rajarajeshwari Medical College and Hospital (Cardiology Unit) from January 5, 2015 to January 20, 2017 were included. The detail history was taken and examination was done. Echocardiography was done in all patients.
RESULTS188 patients with LBBB were studied. Mean age was 63 yrs. 99 were male (52.65%) and 89 were female (47.34%). 76 patients presented with dyspnoea (40.40%) and 60 with chest pain (31.91%); 36 patients were asymptomatic (19.14%); 94 were hypertensive (50%) and 18 were diabetic (9.5%). Left ventricular hypertrophy (LVH) was present in 64 patients (34%) with 47 having diastolic and 12 systolic dysfunction; 47 patients had DCM (25%) and 16 patients had evidence of myocardial infarction (8.5%); 28 patients had normal echocardiography (14.89%); 81 patients had systolic dysfunction (43%).
CONCLUSIONHypertension was a major risk factor for LBBB. Commonest presentation in patients with LBBB was dyspnoea followed by chest pain. LVH was the commonest echocardiographic finding followed by global hyperkinesias and regional wall motion abnormality. More than 50% patients had left ventricular systolic dysfunction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
