Heart failure is a complex clinical syndrome affecting around 70 million individuals globally. It has a prevalence of 2% in Europe and North America and approximately 1% in Asia and South America.

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"), ...

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.

Ejection fraction (EF) measures how well the heart pumps blood. A normal EF is 55% to 70%, meaning the heart pumps out at least half of the blood in its left ventricle with each beat. An EF below 50% ...

Ejection fraction is a measurement doctors can use to help diagnose heart failure. A normal range is between 52% and 72% for males and between 54% and 74% for females. An ejection fraction that’s ...

Introduction: Cardiac magnetic resonance (CMR) is the gold standard for assessing left ventricular ejection fraction (LVEF). Artificial intelligence (AI)-based echocardiographic analysis is ...

Ejection fraction (EF) measures the amount of blood pumped out of your heart's lower chambers, or ventricles. It's the percentage of blood that leaves your ventricle when your heart contracts. The ...

End-diastolic volume is the amount of blood that is in the ventricles before the heart contracts. Doctors use end-diastolic volume to estimate the heart’s preload volume and to calculate stroke volume ...
