Empagliflozin: Primus Inter Pares Among Sodium–Glucose Cotransporter-2 Inhibitors?

Abstract

Sodium/glucose cotransporter 2 (SGLT2) inhibitors are a novel class of anti-diabetic medications which have proved capable of providing breakthrough cardiovascular benefits in a variety of clinical scenarios, including patients with heart failure or obesity, irrespective of diabetic status. Several SGLT2 inhibitors are available, but the most prominent ones are canagliflozin, dapagliflozin, and empagliflozin. Several studies have focused on empagliflozin, and its effects on the risk of heart failure incidence and recurrences. Most recently, empagliflozin has been recently tested in patients with recent myocardial infarction in the EMPAgliflozin on Hospitalization for Heart Failure and Mortality in Patients With aCuTe Myocardial Infarction (EMPACT-MI) randomized trial, with apparently ambiguous findings. The present viewpoint succinctly illustrates the main features of SGLT2 inhibitors as a pharmacologic class, their ever expanding role as a cardiovascular medication, and the comparative effectiveness of different individual SGLT2 inhibitors, explicitly commenting on the recent data on empagliflozin in patients with acute myocardial infarction. The reader will find in this article a poignant perspective on this novel avenue for cardiovascular prevention and treatment, which greatly expands the management armamentarium of cardiovascular practitioners. Indeed, we make the case that SGLT2 inhibitors have a clearly favorable class effect, with differences between individual agents mainly suitable for personalization of care and minimization of side effects.
