DIABETES: Metformin — a cardiovascular moderator of DPP4 inhibitors?
Three cardiovascular outcome trials failed to show superiority of DPP4 inhibitors compared with placebo in patients with type 2 diabetes mellitus and high cardiovascular risk, a rather disappointing finding. Now, a post hoc subgroup analysis suggests that patients treated with metformin at baseline might benefit from DPP4 inhibitors in contrast with metformin non-users.
