Sodium-glucose cotransporter 2 inhibitors reduce the risk of incident type 2 diabetes in people with heart failure without diabetes: An analysis of real-world, cohort data
Abstract
AIM: Sodium-glucose cotransporter 2 inhibitors (SGLT2is), used as a glucose-lowering therapy in people with type 2 diabetes (T2D), have significant cardiorenal benefits, reducing hospitalization for heart failure (HF) and cardiovascular mortality in patients with and without T2D. Recent clinical trial evidence suggests their potential utility in preventing incident T2D among the high-risk HF populations. Therefore, we aimed to assess whether this finding was reproducible in a real-world setting.
METHODS: We performed a retrospective cohort analysis of 484 643 patients with HF, without baseline diabetes, prescribed either angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers with/without SGLT2is (treatment, n = 42 018; reference, n = 442 625) across 95 global health care organizations, using a large real-world ecosystem. Propensity score matching balanced arms 1:1 for confounders (n = 39 168 each arm). Subgroup analysis further evaluated the impact on patients with prediabetes and the efficacy of dapagliflozin/empagliflozin, specifically, on incident T2D and secondary outcomes, including all-cause mortality, acute pulmonary oedema and hospitalization.
RESULTS: Treatment with SGLT2is significantly reduced incident T2D {hazard ratio (HR) 0.71 [95% confidence interval (CI) 0.63, 0.75]} in patients with HF. The analysis of patients with prediabetes found that SGLT2is further reduced incident T2D [HR 0.62 (95% CI 0.45, 0.80)]. The magnitude of reduction in…
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: 484 participants or records.
