SGLT2i vs DPP4i tied with reduced mortality and HF readmission risk in T2D patients with HF

Key clinical point: Sodium-glucose cotransporter-2 inhibitor (SGLT2i) vs dipeptidyl peptidase-4 inhibitor (DPP4i) use at discharge was associated with a lower risk for 1-year all-cause mortality and heart failure (HF) readmission in hospitalized patients with HF and type 2 diabetes (T2D) in a superaged society.

Major finding: Overall, 71.91% of patients were ≥75 years old. SGLT2i vs DPP4i significantly reduced the risk for 1-year all-cause mortality (adjusted hazard ratio [aHR] 0.70; 95% CI 0.56-0.89) and HF readmission (aHRk 0.52; 95% CI 0.45-0.61), with findings being similar among very elderly patients (age, ≥75 years).

Study details: Findings are from a retrospective study including patients hospitalized with the first episode of acute HF and T2D, of which 2101 patients with T2D receiving SGLT2i were propensity score-matched with 2101 of those receiving DPP4i.
