Differential cardiovascular and renal benefits of SGLT2 inhibitors and GLP1 receptor agonists in patients with type 2 diabetes mellitus

Abstract

Background: The differential benefits of sodium-glucose cotransporter 2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP1RA) in cardiovascular or renal outcomes have not been fully investigated. Methods: Patients with diabetes prescribed SGLT2i or GLP1RA were retrospectively identified. Patients treated with antihyperglycemic medications other than SGLT2i or GLP1RA were used as a control group. Primary outcomes were composite ischemic events (acute coronary syndrome, coronary revascularization, and stroke) and a composite of heart failure and renal events (hospitalization for heart failure, renal death, initiation of renal replacement therapy, and renal admission). Results: During a median 38.7 months of follow-up, the incidence of composite ischemic events tended to be lower in the GLP1RA group (annualized rate 0.82% per person-year) than in the other groups (1.68% per person-year in the SGLT2i group and 1.36% per person-year in the control group). The risk of a composite of heart failure and renal outcomes was significantly lower in the SGLT2i group than in the GLP1RA and control groups (0.86% per person-year, 2.33% per person-year, and 1.48% per person-year, respectively). The SGLT2i group had a slower decline in renal function over time compared to that in other groups. Conclusions: SGLT2i showed more benefits in heart failure and renal outcomes, whereas GLP1RA tended to have more favorable ischemic outcomes.N
