Does long-term prognosis (all-cause mortality and HF hospitalization) differ among patients with reduced, mid-range, and preserved ejection fraction?
Patients with HFmrEF have a more favorable long-term prognosis regarding mortality and heart failure hospitalizations compared to those with HFrEF or HFpEF.
In summary, patients with HFmrEF had the lowest incidence of all-cause mortality and HF hospitalization, while the highest all-cause mortality and HF hospitalization rates were HFpEF and HFrEF patients, respectively.
Liang et al. (Sat,) studied this question.
