Empagliflozin and Dapagliflozin Outcomes in Heart Failure
Abstract
IMPORTANCE: Sodium-glucose cotransporter-2 inhibitors have emerged as important therapeutic options for heart failure (HF). However, their comparative clinical effectiveness remains uncertain.
OBJECTIVE: To compare the outcomes associated with dapagliflozin and empagliflozin use in patients diagnosed with HF.
DESIGN, SETTING, AND PARTICIPANTS: This cohort study used a clinical data warehouse platform shared by 8 medical centers affiliated with The Catholic University of Korea to screen all patients who were diagnosed with HF between January 2021 and November 2023 at these 8 medical centers. Patients were taking either dapagliflozin or empagliflozin and underwent transthoracic echocardiography. One-to-one propensity score matching was performed to ensure comparable baseline characteristics between groups. The propensity score-matched cohort was stratified by left ventricular ejection fraction (LVEF) into subgroups: HF with reduced ejection fraction group had an LVEF of 40% or lower, HF with mildly reduced ejection fraction group had an LVEF of 41% to 49%, and HF with preserved ejection fraction group had an LVEF of 50% or higher. Statistical analyses were performed from December 2023 to July 2025.
EXPOSURE: All patients received either dapagliflozin or empagliflozin.
MAIN OUTCOMES AND MEASURES: The primary outcome was a composite of cardiovascular death or hospitalization for heart failure. Secondary outcomes included the individual primary outcome components, all-cause…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 4,930 participants or records.
