BackgroundGliflozins are effective drugs for the treatment of type 2 diabetes. They inhibit sodium glucose cotransporter 2 in the proximal renal tubule, leading to increased glucose excretion. On the basis of findings from relevant studies, gliflozins are also increasingly used in clinical practice to treat congestive heart failure and renal failure.MethodsThis review is based on pertinent publications retrieved from a selective literature search in PubMed and GoogleScholar.ResultsCardiovascular safety studies revealed early on that gliflozins can lower the hospitalization rate of patients suffering from congestive heart failure with a reduced leftventricular ejection fraction (HFrEF). They also showed favorable effects on multiple renal endpoints. In recent years, studies such as DAPA-HF and CREDENCE have further documented the benefit of gliflozins in the treatment of congestive heart failure and renal failure in patients with type 2 diabetes, and gliflozins have accordingly been incorporated into the pertinent guidelines. In the recently published EMPEROR-Reduced trial, empagliflozin was found to significantly lower the frequency of a combined cardiovascular endpoint in patients with HFrEF (19.4 % versus 24.7%; hazard ratio [HR] 0.75; 95% confidence interval [0.65; 0.86]; number needed to treat [NNT] 19, p <0.001). In the DAPA-CKD trial, which was also recently published, dapagliflozin was found to significantly lower the frequency of a combined renal endpoint (9.2% versus 14.5%; HR 0.61 [0.51; 0.72]; NNT 19; p <0.001).ConclusionOn the basis of findings from specific studies, gliflozins will henceforth be a major class of drug for the treatment of HFrEF and renal failure, independently of the presence of type 2 diabetes.
