Abstract excerpt

BACKGROUND: Few therapies improve outcomes in patients with heart failure with preserved ejection fraction (HFpEF). If left bundle-branch block (LBBB) is associated with left ventricular dyssynchrony and impaired cardiac performance in HFpEF, cardiac resynchronization therapy could be a promising treatment. METHODS: We performed a cross-sectional analysis of selected patients with HFpEF (ejection fraction ≥50%)...
