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 ejection fraction is between 55% to 70%. A low ejection fraction can be a sign of heart failure. Ejection fraction (EF) ...

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 ...

The therapeutic efficacy of the cardiac glycoside digitoxin in patients with heart failure and reduced ejection fraction is not established. In this international, double-blind, placebo-controlled ...

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 ...
