SGLT-2 inhibitors as cardio-renal protective agents

Despite remarkable advances in diabetes care, patients with type 2 diabetes are still burdened by higher morbidity and mortality than non-diabetic individuals. Atherosclerotic cardiovascular disease, heart failure, and chronic kidney disease represent the most relevant causes of morbidity and mortality and sustain each other in a vicious circle. Cardiovascular diseases are the main cause of death in patients with chronic kidney disease, and, in turn, chronic kidney disease is a significant contributor to the risk of major cardiovascular events and hospitalization for heart failure. Cardiovascular outcome trials with SGLT-2 inhibitors in type 2 diabetes yielded unprecedented results on prevention of worsening heart failure and renal disease progression and mortality, further confirmed by randomized controlled trials in patients with baseline heart failure and chronic kidney disease, with or without diabetes, and observations from the real-world setting. However, the evidence regarding SGLT-2 inhibitors benefit on atherosclerotic cardiovascular events is conflicting. Hence, SGLT-2 inhibitors represent a remarkably valuable weapon in diabetes management, to be used in the context of a multi-targeted treatment strategy to address the many issues of this multifaceted disease.
