Sodium-glucose cotransporter-2 inhibitors (SGLT-2i) improve the risk for heart and kidney failure. However, their effects on major atherosclerotic cardiovascular events (MACE) are less clear. Although outcomes trials of drugs for diabetes were not powered to prove superiority, the totality of trial data yields an estimate of ∼11% relative reduction for MACE (HR 0.89, 95%CI 0.82-0.96) and neutral on stroke (HR 0.92, 95%CI 0.79-1.08). In animal models, SGLT-2i favorably affects plaque size, composition, and inflammatory pathways; human data in this regard are lacking. Ongoing trials are evaluating SGLT-2i efficacy in heart failure, kidney disease, and postmyocardial infarction populations, independent of diabetes status.
