Association of Left Bundle Branch Block with Systolic Dysfunction of Left Ventricle

Abstract

Objective: The study was conducted to know the association of left bundle branch block with systolic dysfunction of left ventricle in our population because it carries poor prognosis.

Study Design: Descriptive study

Place and Duration of Study: This study was conducted at the Cardiology department of Bahawal Victoria Hospital, Bahawalpur from July 2016 to January 2017.

Materials and Methods: The study included 93 patients with both genders between ages 40-70 years. Those having the previous history of ischemic heart disease and cardiomyopathies were excluded. In all patients, severity of systolic dysfunction of left ventricle was assessed by echocardiography.

Results: Age of the patient’s ranges between 58.48 ± 8.58 years. Out of the 93 patients, males and females were72 (77.42%) and 21(22.58%) with ratio of 3.4:1. Range of BMI was 28.09 ± 4.59 kg/m2.Systolic dysfunction of left ventricle was found in 41 (44.09%) patients, whereas   52 (55.91%) patients were found to have normal function.

Conclusion: This study shows a strong association of systolic dysfunction of left ventricle with left bundle branch block.
