Conversely, RASI//ARNI use was linked to a lower risk of cardiovascular death (hazard ratio = 0.82, 95% CI: 0.71-0.94) but not HHF (hazard ratio = 0.995, 95% CI: 0.924-1.07).Landmark analysis showed no significant difference in outcomes for follow-up durations exceeding two years.MRA had a neutral effect on cardiovascular death and HHF, while RASI/ARNI was associated with a lower risk of cardiovascular death. RASI/ARNI may be more beneficial than MRA for HFmrEF patients. Regular re-evaluation is essential to adjust heart failure treatment.
