Association of Left and Right Branch Blocks with Clinical Outcomes in Patients with Heart Failure with Preserved Ejection Fraction.

ABSTRACT: The associations of left bundle branch block (LBBB) and right bundle branch block (RBBB) with cardiovascular (CV) outcomes compared with normal QRS in heart failure patients with preserved ejection fraction (HFpEF) are unclear. We sought to determine CV morbidity, mortality, and total costs associated with LBBB and RBBB in acute HFpEF compared with those without BBB. A cross-sectional study using the 2019 NIS database analyzed adult HFpEF hospitalizations for acute heart failure, categorizing patients by LBBB, RBBB, or normal QRS. Clinical outcomes included atrial fibrillation (AF), ventricular fibrillation (VF), complete heart block (CHB), sick sinus syndrome (SSS), cardiac arrest (CA), hospitalization costs, and in-hospital mortality. Associations between BBB types and outcomes were asse
