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"), ...

The tools may help address underdiagnosis in this area, though there is still room for improvement in screening performance.

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 ...

Objective: To provide an overview of heart failure with preserved ejection fraction (HFPEF), as well as its pathophysiology, diagnosis, and clinical evidence regarding its pharmacologic management.

Panel A shows a cross-section of a normal heart (top) and an endomyocardial biopsy sample from a normal heart (bottom; with hematoxylin and eosin staining) that shows normal histologic characteristics ...

Medically reviewed by Jeffrey S. Lander, MD Key Takeaways Heart failure happens when the heart can’t pump enough blood throughout the body.Chronic heart failure often happens because of other medical ...

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 ...

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 ...
