Efficacy of Continuing SGLT2 Inhibitors on Outcomes in Patients with Acute Decompensated Heart Failure

Sodium-glucose cotransporter 2 inhibitor (SGLT2i) reduces mortality and morbidity in patients with chronic heart failure (HF). However, the clinical implication of SGLT2i therapy in patients with acute decompensated HF remains uncertain. We prospectively studied 86 type 2 diabetic mellitus (T2DM) patients (71.8 +/- 12.1 years, 55 men) who were hospitalized for acute decompensated HF and received SGLT2i during the index hospitalization. Among the patients, 56 continued SGLT2i at discharge and 30 did not. The continued group experienced fewer HF re-hospitalizations than the discontinued group (24% versus 39%, P = 0.008) with a hazard ratio of 0.29 (95% confidence interval 0.10-0.85) adjusted for other significant potential confounders. In conclusion, long-term SGLT2i therapy might prevent unplanned HF re-hospitalization in patients with T2DM and acute decompensated HF.
