Left ventricular systolic dysfunction (LVSD) was common in patients receiving right ventricular pacing, and a history of ischaemic heart disease and a high ventricular pacing burden were identified as ...

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 ...

Background The Forrester classification remains a cornerstone for assessing haemodynamic status in heart failure, yet its ...

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 ...

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 ...

Refining transverse aortic constriction (TAC) models helps reduce variability and improve reproducibility in heart failure research.
