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.

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 ...

How would you further evaluate and treat this patient? Heart failure with preserved ejection fraction is a heterogeneous syndrome. The diagnosis of the condition requires ruling out potential ...

Your heart has two phases for each heartbeat: A low ejection fraction lets a doctor know that the active pumping phase of the heart isn't working. It's usually tied to some, but not all ...

A low ejection fraction, which is defined as 40% or below, indicates that the heart cannot pump enough blood to meet the body’s requirements. Low ejection fraction symptoms include fatigue ...

An international team of researchers at the University of Manchester, Baylor College of Medicine and collaborating institutions has discovered a natural mechanism that protects the heart from ...

Another type is heart failure with reduced ejection fraction (HFrEF), in which the heart is unable to pump blood effectively. The function of the left ventricle is to pump oxygenated blood to the ...

[21] This was a smaller study that enrolled 74 patients 65 years and older with NYHA class II or III heart failure (defined by the Framingham criteria) and an ejection fraction ≥40%. Background ...

It became clear that ejection fraction distinguished both response to treatments and prognosis. After a stint as "diastolic heart failure," heart failure with preserved ejection fraction (HFpEF ...
