Abstract
Background: The efficacy of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in patients with acute chronic heart failure (HF) is increasingly being reported. However, it is not clear when SGLT2i should be initiated in patients with acute decompensated HF (ADHF) after hospitalization. We retrospectively analyzed ADHF patients with newly prescribed SGLT2i.Methods and Results: Among the 694 patients hospitalized due to HF between May 2019 and May 2022, data were extracted for 168 patients with newly prescribed SGLT2i during the index hospitalization. These patients were divided into 2 groups: and early group (92 patients who started SGLT2i within 2 days of admission) and a late group (76 patients who started SGLT2i after 3 days). Clinical characteristics were comparable between the 2 groups. The date of cardiac rehabilitation initiation was significantly earlier in the early than late group (2.5±1.2 vs. 3.8±2.2 days; P<0.001). Hospital stay was significantly shorter in the early group (16.4±6.5 vs. 24.2±16.0 days; P<0.001). Although there were significantly fewer HF readmissions within 3 months in the early group (2.1% vs. 10.5%; P=0.044), the association disappeared in a multivariate analysis including clinical confounders.Conclusions: Early initiation of SGLT2i may shorten hospital stays.
