SGLT-2 Inhibitors for Patients with Heart Failure: What Have We Learned Recently?

Purpose of Review: In this review, we discuss the mechanisms of action of sodium-glucose cotransporter-2 inhibitors (SGLT-2i) and the purported protective effects for mitigating heart failure (HF)-related outcomes. Recent Findings: Major randomized clinical trials have demonstrated the cardiovascular safety and efficacy of SGLT-2i among patients without known HF and those with established HF with reduced ejection fraction or preserved ejection fraction (HFrEF and HFpEF respectively). Recent HF guidelines have incorporated SGLT-2i in HF treatment algorithms. Summary: SGLT-2i have emerged as a novel treatment for both prevention of HF and reduction of cardiovascular morbidity and mortality among patients with existing HFrEF or HFpEF.
