Is your heart functioning properly? There is a test which can measure this, which is often recommended by medical professionals. Ejection fraction (EF) is a measurement, expressed as a percentage, of ...

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) ...

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 benefit of beta-blockers after myocardial infarction in patients with a preserved left ventricular ejection fraction (LVEF) is unclear. We conducted a meta-analysis at the individual-patient level ...

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 ...

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 ...
