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% ...

Nitrates are commonly prescribed to enhance activity tolerance in patients with heart failure and a preserved ejection fraction. We compared the effect of isosorbide mononitrate or placebo on daily ...

How does the ejection fraction (EF) calculated during the sestamibi imaging of a cardiac stress test correlate with an EF measured with a two-dimensional cardiogram? — Patricia Gable, FNP-BC, Cadillac ...

Ejection fraction is a measurement doctors can use to help diagnose heart failure. A normal range is between 52% and 72% for males and between 54% and 74% for females. An ejection fraction that’s ...

Observational studies suggest that conventional right ventricular apical pacing may have a deleterious effect on left ventricular function. In this study, we examined whether biventricular pacing is ...
