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"), ...

We describe the case of a previously healthy adolescent female who presented with chest discomfort and near-syncope, accompanied by trifascicular block and hypotension. Her clinical condition rapidly ...

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 Marathon running has numerous cardiovascular effects. Studies report transient physiological changes, while others ...

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 ...

Medically reviewed by Christopher Lee, MD Systolic congestive heart failure involves the left side of your heart losing its ability to pump effectively.Common symptoms include shortness of breath, ...

Left- and right-sided heart failure can both cause different symptoms. For instance, people with left-sided heart failure may experience trouble breathing, while people with right-sided heart failure ...

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 ...
