Question: 1 / 20

An ejection fraction of 50% would be classified as?

Reduced

Preserved

An ejection fraction of 50% is classified as reduced. Ejection fraction (EF) measures the percentage of blood that is pumped out of the ventricles with each contraction of the heart. A normal ejection fraction typically ranges from 55% to 70%. Values below this range indicate a decrease in the heart's pumping efficiency. An EF of 50% suggests that the heart is not functioning optimally, as it is below the accepted normal threshold, aligning it more with reduced cardiac output. This classification is critical in diagnosing and managing heart conditions, as it indicates potential heart failure or other cardiac dysfunctions requiring further assessment and intervention.
