Outcomes in patients with heart failure with preserved, borderline, and reduced ejection fraction in the Medicare population

Background Studies on outcomes among patients with heart failure (HF) with preserved left ventricular ejection fraction (HF p EF), borderline left ventricular ejection fraction (HF b EF), and reduced left ventricular ejection fraction (HF r EF) remain limited. We sought to characterize mortality and readmission in patients with HF in the contemporary era. Methods Get With The Guidelines–HF was linked to Medicare data for longitudinal follow-up. Patients were grouped into HF p EF (left ventricular ejection fraction [EF] ≥50%), HF b EF (40% ≤ EF < 50%), and HF r EF (EF
