It is a common perception that approximately 50% of heart failure (HF) patients present with a normal or near-normal left ventricular (LV) ejection fraction ("HF with preserved systolic function"), ...

Cardiac physiologic pacing, also known as cardiac resynchronization therapy, is indicated in patients with heart failure, reduced left ventricular ejection fraction (LVEF) of 50% or less, and either a ...

Cardiomyopathy is the leading cause of mortality in patients with DMD. Compared with their healthy counterparts, patients with DMD — including those with preserved left ventricular ejection fraction ...

This Journal feature begins with a case vignette highlighting a common clinical problem. Evidence supporting various strategies is then presented, followed by a review of formal guidelines, when they ...

LBBB is linked to electrical abnormalities, causing inefficient heart pumping, dilation, and systolic dysfunction. The study found LBBB associated with increased heart failure risk, surpassing other ...
