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) ...

This Journal feature begins with a case vignette highlighting a common clinical problem. Evidence supporting various strategies is then presented, followed by a review of formal guidelines, when they ...

May 6, 2011 (San Francisco, California) — Ablation of ventricular tachycardia (VT) in patients with verylow ejection fractions (EFs) results in high rates of early recurrence compared with individuals ...

Beta-blocker therapy after myocardial infarction (MI) failed to lower the rate of all-cause death, MI, or heart failure in patients with a left ventricular ejection fraction (LVEF) of at least 50%, ...

Heart failure with preserved ejection fraction (HFpEF) is a condition in which the heart does not fill with blood properly. In HFpEF, the heart can pump normally, but the heart is stiff and cannot ...

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 ...
