Predictive Value of Bundle Branch Blocks among Heart Failure Patients

Abstract

Introduction: The prognosis of left and right bundle branch blockages (LBBB and RBBB) in hospitalized heart failure (HF) patients remains unknown. There are debates over the type of bundle branch block (BBB) that is associated with an increased mortality risk in people with heart failure (HF). Aim: The purpose of this study was to investigate the predictive value of bundle branch blocks in heart failure patients. Methods: This prospective observational study included all inpatient admissions with heart failure from January 2023 to December 2023 in our institution. Age group of 18- 90 years is included in this study. Data on baseline characteristics included demographics, clinical and post procedure outcomes. Results: In the present study, the ages of the individuals participating were classified. The largest age group was 70-79 years (32%), followed by 60-69 years (27.3%) and 50-59 years (21.3%), with fewer participants younger than 50 years (12%) or older than 79 years (7.3%). The study participants were predominantly male (64%), and the remaining 36% were female. In this study, the presence of bundle branch block (BBB) among participants is shown. The majority of participants (78.7%) did not have BBB, while 21.3% had BBB. Among participants with BBB, the majority had left bundle branch block (LBBB) (75%), while 25% had right bundle branch block (RBBB). Conclusion: Heart failure patients with LBBB had a significant clinical severity of heart failure at presentation and were more likely to have mortality or hospitalisation for heart failure or cardiovascular events than those without BBB. On the contrary, RBBB did not significantly predict negative outcomes.
