Role of SGLT2 inhibitors (gliflozins) in heart failure

Gliflozins (sodium-glucose cotransporter type 2 inhibitors or SGLT2is) reduced hospitalisations for heart failure in all large prospective cardiovascular outcome trials performed in patients with type 2 diabetes at risk of cardiovascular disease. This protective effect was confirmed in two dedicated trials that specifically targeted patients with heart failure and reduced left ventricular ejection fraction (DAPA-HF with dapagliflozin and EMPEROR-reduced with empagliflozin) and in two trials in patients with preserved left ventricular ejection fraction (EMPEROR-preserved with empagliflozin and DELIVER with dapagliflozin), independently of the presence of diabetes. These favourable results contribute to give a privileged position to SGLT2is in recent international guidelines produced by diabetologists and cardiologists.
