A Practical Guide for Cardiologists to the Pharmacological Treatment of Patients with Type 2 Diabetes and Cardiovascular Disease

Patients with type 2 diabetes are at increased cardiovascular risk. Until recently, reductions in HbA and the use of specific glucose-lowering agents have not had a clear, reproducible benefit in reducing the incidence of cardiovascular disease. However, over the past 5 years, members of two categories of diabetes medications, sodium-glucose cotransporter 2 inhibitors and glucagon-like peptide-1 receptor agonists, have been associated with improved rates of major adverse cardiovascular events when used in high-risk type 2 diabetes patients. Importantly, these effects are not necessarily linked to these agents' effects on HbA . Sodium-glucose cotransporter 2 inhibitors have also been associated with reductions in heart failure hospitalization, a benefit that appears to extend to individuals without diabetes with established heart failure. Cardiovascular specialists should become familiar with these emerging data and be prepared to implement corresponding strategies in their practice to improve the cardiovascular outcomes of their patients. Recent clinical trial data and the changing landscape of corresponding professional guidelines are reviewed. Practical recommendations for safe prescribing of these anti-diabetes drugs are provided.
