Background: It remains uncertain whether the use of sodium-glucose cotransporter 2 inhibitors (SGLT2is) and incretin-based drugs is associated with a reduced risk of major adverse cardiovascular events (MACE) compared with that of thiazolidinediones (TZDs) in people with type 2 diabetes and stroke.

Objectives: To compare the effectiveness of SGLT2is, incretin-based drugs, and TZDs on MACE in people with type 2 diabetes and prior stroke.

Methods: We did a population-based cohort study involving 117,355 individuals who underwent health checkups under the Korean National Health Insurance Service from 2014 to June 2021 and followed up until December 2021. The primary outcome was MACE, defined as a composite of myocardial infarction, ischemic stroke, and all-cause death. We used propensity score weighting for balancing baseline covariates between treatment groups. Weighted cox proportional regression analyses were used to estimate the association of treatments with MACE after adjusting confounders.

Results: In a new-user cohort, the incidence rate of MACE was 547, 679, and 625 per 1,000 person-years in the SGLT2i, incretin-based drug, and TZD groups, respectively. Compared with the TZD group, the risk of MACE was significantly reduced in the SGLT2i group (adjusted hazard ratio [HR] 0.87; 95% CI 0.79-0.96) but increased in the incretin-based drug group (adjusted HR 1.11; 95% CI 1.03-1.19). No significant differences were observed in the risk of myocardial infarction and ischemic stroke between the groups. The risk of all-cause death was significantly increased in the incretin-based drug group (adjusted HR 1.14; 95% CI 1.03-1.25) compared with the TZD group.

Conclusion: In this population-based study of people with type 2 diabetes and stroke, SGLT2is were associated with a reduced risk of MACE compared with incretin-based drugs and TZDs. Incretin-based drugs were associated with an increased risk of MACE compared with TZDs.
