In patients with Type 2 Diabetes and Heart Failure with reduced ejection fraction (HFrEF), treatment with GLP-1 receptor agonists significantly reduces all-cause mortality and major cardiovascular events compared to DPP-4 inhibitors.

If you have Type 2 Diabetes and reduced heart function (HFrEF), GLP-1 medications (like semaglutide or dulaglutide) are associated with a significantly lower risk of death and heart-related hospitalizations compared to DPP-4 inhibitors. This benefit appears early and persists over 5 years, regardless of age or sex. Discuss these options with your cardiologist, as they may offer cardiovascular protection beyond blood sugar control.

ModerateSupportsMEDIUM confidence
The GLP-1 RA user group demonstrated a reduced hazard ratio (HR, 95 % confidence interval) over 5 years compared with the DPP4i user group for all-cause mortality (0.62, 0.59–0.66, P < 0.001)... and heart failure exacerbation (0.83, 0.81–0.86, P < 0.001).
