Benefits of SGLT2i for the Treatment of Heart Failure Irrespective of Diabetes Diagnosis: A State-of-the-Art Review

Morbidity and mortality associated with heart failure (HF) has remained high despite advances in therapy. Furthermore, HF-associated risk in patients with type 2 diabetes mellitus (T2D) is even higher than in patients without T2D owing to the strong reciprocal relationship between conditions. However, until recently, no therapy to treat patients with diabetes also reduced cardiovascular risks related to HF. Recent clinical studies (DAPA-HF, EMPEROR-Reduced and EMPEROR-Preserved, SOLOIST-WHF trial) and meta-analysis have demonstrated that sodium–glucose cotransporter-2 inhibitors (SGLT2i) are among the first antidiabetic drugs capable of reducing cardiovascular risks related to HF and improving the prognosis of patients with and without diabetes. Their pleiotropic mechanisms of action place them at the intersection of hemodynamic, metabolic, and neurohumoral pathways, with clear advantages for treating these patients independent of its glucose-lowering effect. Moreover, the benefits of SGLT2i were consistent across the cardiorenal continuum in different populations and clinical settings, which has led to different guidelines introducing SGLT2i as a first-line treatment for HF.
