What term best describes heart failure with reduced ejection fraction?

Explanation:
Understanding how heart failure is classified by ejection fraction helps explain why this term fits best. Ejection fraction is the percentage of blood the left ventricle pumps out with each beat, with normal values around 55–70%. When the heart’s pumping is impaired and the EF is reduced, this pattern is described as heart failure with reduced ejection fraction. The usual threshold is EF <40%, indicating systolic dysfunction. The label used for this condition is heart failure with reduced ejection fraction (HFrEF). In contrast, heart failure with preserved ejection fraction describes a diastolic problem where the EF remains normal or near-normal. Right-sided heart failure refers to failure affecting the right side of the heart and its systemic congestion, and does not specify a reduced EF. Acute heart failure describes a time frame of symptom onset or worsening, not the EF status. Therefore, the best term for heart failure characterized by reduced ejection fraction is HFrEF.
