Association of Prior Left Ventricular Ejection Fraction With Clinical Outcomes in Patients With Heart Failure With Midrange Ejection Fraction.

ABSTRACT:

Importance

Patients categorized as having heart failure (HF) with left ventricular ejection fraction (LVEF) in the midrange between 40% and 50% (HFmrEF) are known to be at increased risk of future events. Although patients can transition into the midrange through either improvement or deterioration in their LVEF, there is limited information available assessing the association of directional change in LVEF with future events. Understanding the association between change in LVEF and the clinical course of patients with HFmrEF would be of value in guiding management strategies.

Objective

To determine whether risk of clinical events experienced by patients with HFmrEF varies according to whether LVEF improved or deteriorated into the range of 40% to 50% from previous measuremen
