Abstract
A demonstration of cardiovascular safety is mandatory for all newly developed glucose-lowering agents, including insulin analogues. The vascular benefit of insulin is evident from the Diabetes Control and Complication Trial (DCCT) and United Kingdom Prospective Diabetes Study (UKPDS), and the cardiovascular safety of insulin glargine has been demonstrated in individuals with newly diagnosed diabetes or prediabetes in the ORIGIN trial (Outcome Reduction with an Initial Glargine Intervention). The top-line results of DEVOTE (Trial Comparing Cardiovascular Safety of Insulin Degludec vs. Insulin Glargine in Patients with Type 2 Diabetes at High Risk of Cardiovascular Events) have proven the cardiovascular safety of insulin degludec in persons with type 2 diabetes. In this commentary I discuss the interrelationship of insulin and cardiovascular health, while comparing the results of DEVOTE and ORIGIN.
