Surprises in cardiology: efficacy of gliflozines in heart failure even in the absence of diabetes.

It is now well-established that the therapy of type II diabetes mellitus has undergone a radical change in the past 15 years: countless innovative drugs, such as SGLT2I, able to guarantee an optimization of glycaemic control without causing hypoglycaemia, today represent real therapeutic cornerstones not only for the intrinsic ability of these molecules to ensure better glycaemic control but also for the effects they exert on the cardiovascular system. Several pioneering clinical trials, such as EMPA-REG, CANVAS, and DECLARE-TIMI-58, have demonstrated clear benefits of empagliflozin, canagliflozin, and dapagliflozin, respectively, in reducing cardiovascular risk and diabetes-associated macrovascular complications in the diabetic population. The promising results that emerged from these trials represent the spark that triggered a series of studies aimed at evaluating the efficacy of gliflozines in the treatment of patients with heart failure even in the absence of diabetes. Preliminary results confirm the efficacy of SGLT2I in the treatment of this population, representing a real therapeutic revolution.
