A Number: An ef is a measure of what fraction of the heart's blood is ejected out into the aorta with each beat. Normal is > 50% (range ~50-70%). Less than 35-40% puts one at increased risk of serious heart rhythm problems. Medications can improve the ejection fraction. This number, however has substantial limitations cardiologists could discuss at length and is not everything in heart failure.

Ejection fraction: The ejection fraction is an approximation of the percentage of the volume of blood moved each time the heart contracts. It is a measure of function or strength a normal heart moves approximately 60-65%. The lower the number is a approximation of the severity of disease. This is not entirely irreversible can be improved with medical therapy.
