Popis: The micro/macrovascular complications of diabetes cause considerable morbidity and premature mortality. The SGLT2 inhibitors are the first diabetes medications with significant benefits on microvascular disease (nephropathy) and macrovascular cardiovascular disease. In this review, we evaluate one of the potential mechanisms for these cardiorenal benefits—the production of ketones, their benefits, and risks. In recent cardiovascular outcome trials (CVOTs), the SGLT2 inhibitors demonstrated significant cardiorenal benefits and they are now approved to reduce CV events/death, heart failure hospitalization, and progression to end-stage renal disease. Glucosuria induced by the SGLT2 inhibitors leads to increased ketone production. Ketones are an efficient fuel source and can improve myocardial and renal function. Further, the ketone body beta-hydroxybutyrate exhibits anti-inflammatory/anti-oxidative actions, which favorably impact myocardial and renal remodeling/fibrosis. Uncontrolled ketogenesis leads to ketoacidosis, especially during conditions of acute illness and excessive insulin dose reductions. The SGLT2 inhibitors have demonstrated significant cardiorenal benefits in large CVOTs. Studies are in progress to elucidate whether SGLT2 inhibitor–induced low-grade hyperketonemia contributes to these benefits.
