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% ...
An international team of researchers has discovered a natural mechanism that protects the heart from heart failure with preserved ejection fraction (HFpEF), a serious condition in need of effective ...
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 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 ...
