Ejection fraction refers to how much blood the heart pumps out during a contraction. An abnormal ejection fraction can be a sign of heart failure. Some people might need treatment to improve their ...

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 (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 ...

Heart failure is a heterogeneous syndrome. Approximately 30–50% of patients with heart failure have normal or near normal left ventricle function. Several epidemiological studies confirm that the ...

Heart failure in which left ventricular ejection fraction recovers into the normal range has many unknowns. Andrew Perry, MD, discusses key management strategies with Jane Wilcox, MD, of Northwestern ...

Heart failure with preserved ejection fraction (HFpEF) is a type of heart failure that affects the left side of the heart. It occurs when the lower left chamber of the heart, called the left ventricle ...
