Cardiovascular Outcomes SGLT-2 Inhibitors Versus GLP-1 Receptor Agonists

Cardiovascular Outcomes of Type 2 Diabetic Patients Treated With SGLT-2 Inhibitors Versus GLP-1 Receptor Agonists in Real-life. An Observational Study Using Clinical-administrative Data

Patients with type 2 diabetes (T2D) suffer from an excess risk of adverse cardiovascular events. Recently, two classes of glucose lowering agents, namely SGLT-2 inhibitors (SGLT2i) and GLP-1 receptor agonists (GLP-1RA), have proved superior to placebo in protecting T2D patients from cardiovascular events in dedicated trials. Patient populations in such trials were mainly composed of T2D individuals with established cardiovascular disease (CVD) or at very high risk for CVD. In addition, no clinical trial has so far compared cardiovascular outcomes of T2D associated with SGLT2i versus GLP-1RA. In addition, whether different results would incur in patients at lower CVD risk is unclear. On this basis, we designed this retrospective real-world study to compare cardiovascular outcomes of patients newly treated with SGLT2i versus GLP-1RA in routine clinical practice
