What is indicated by a left ventricle ejection fraction above 55%?

A left ventricle ejection fraction (LVEF) above 55% is indicative of normal ventricular function. The ejection fraction is a measurement of the percentage of blood that is pumped out of the ventricles with each contraction. Typically, a normal ejection fraction ranges from about 55% to 70%. When the ejection fraction is above this threshold, it suggests that the heart is functioning effectively, providing sufficient cardiac output to meet the body’s demands during various activities.

Maintaining a healthy ejection fraction is crucial for ensuring that the organs receive adequate blood supply, thereby improving overall cardiovascular health. Values below the normal range may suggest potential heart failure or other cardiac dysfunctions, but an ejection fraction above 55% generally implies that the heart's pumping ability is within the normal limits.
