What does a high Ejection Fraction percentage typically indicate?

A high Ejection Fraction (EF) percentage is typically indicative of good ventricular contractility. Ejection Fraction is a measurement of the percentage of blood that is pumped out of the heart's ventricles with each contraction. A normal EF ranges from about 55% to 70%. A higher percentage suggests that the heart is effectively contracting and is able to deliver an adequate amount of blood to the body, which is a sign of good cardiac function.

This measurement is crucial for assessing heart health, as a higher EF often correlates with better overall heart performance and indicates that the heart muscle is functioning efficiently. In contrast, low EF values can be associated with heart failure or other cardiac conditions, where the heart's ability to pump effectively is compromised.

The options that involve poor cardiac function, low blood volume, or high blood pressure do not correlate with a high Ejection Fraction. High EF signifies good contractility rather than issues related to these conditions. Understanding Ejection Fraction can provide valuable insight into an individual's cardiovascular health and guide appropriate medical treatments.
