Right ventricular ejection fraction, stroke volume index, 40 and right ventricular end-systolic volume index are informative measures for prognosis and risk stratification. 41 The ratio of stroke ...

For a typical, healthy adult the ejection fraction varies from about 50 to 70 percent. This means that one half or more of the volume of blood in the ventricle is pumped out with every contraction.

“In advanced stages of heart failure with reduced ejection fraction, where volume overload and reduced stroke volume play a key role, a significant regurgitant volume might further increase left ...

September 14, 2009 (Boston, Massachusetts) — Cardiac resynchronization therapy (CRT) can improve symptom status and shrink ventricular volumes in patients with LV ejection fractions higher than ...

In observational studies and clinical trials, the value used to define a “preserved” ejection fraction has ranged from 40 to 55%, but current guidelines recommend a partition value of 50%. 17 ...
