About The Study: The findings of this cohort study underscore a gap between evidence and practice. Two-thirds of patients with newly identified heart failure with reduced ejection fraction did not undergo left ventricular ejection fraction reassessment, limiting opportunities to confirm persistence, evaluate reverse remodeling, and identify candidates for treatment. Receipt of guideline-directed medical therapy was modest across groups, even among patients with persistent heart failure with reduced ejection fraction, who derive the greatest benefit.
