Aims: This study compares the cardiovascular benefits between SGLT2 inhibitors and other glucose-lowering drugs (oGLDs) based on electronic medical record data from a large integrated delivery health system in South Louisiana.

Materials and Methods: Demographic, anthropometric, laboratory and medication prescription information for patients with type 2 diabetes who were new users of SGLT2 inhibitors either as initial treatments or as add-on treatments were obtained from electronic health records. Mediation analysis was performed in demonstrating the association of use of SGLT2 inhibitors and changes of metabolic risk factors with the risk of incident coronary heart disease.

Results: A total of 5,338 new users of SGLT2 inhibitors were matched with 13,821 patients using oGLDs. During a mean follow up of 3.26 years, 2,303 incident cases of coronary heart disease were defined. After adjusting for multiple confounding factors, patients using SGLT2 inhibitors had a lower risk of incident coronary heart disease compared to patients using oGLDs (hazard ratio [HR] 0.63; 95% confidence interval [CI] 0.55-0.72). Patients using SGLT2 inhibitors also had a lower risk of incident coronary heart disease within 6 months (HR 0.32; 95% CI 0.23-0.43), 12 months (HR 0.38; 95% CI0.31-0.48), 24 months (HR 0.49; 95% CI 0.41-0.59) and 36 months (HR 0.59; 95% CI 0.51-0.69), respectively. Reductions in systolic blood pressure attributed the lower risk of coronary heart disease among patients using SGLT2 inhibitors.

Conclusions: Evidence from real world data indicated the contribution of SGLT2 inhibitors to reducing risk of coronary heart disease, as well as the benefits beyond glucose-lowering.
