Chronic Inhibition of Hypoxia-inducible Factor Prolyl 4-hydroxylase Improves Ventricular Performance, Remodeling, and Vascularity After Myocardial Infarction in the Rat

Abstract

Chronic post-myocardial infarction treatment with a selective HIF PHD inhibitor (GSK360A) exerts systemic and local effects by stabilizing HIF-1 alpha signaling and improves long-term ventricular function, remodeling, and vascularity in a model of established ventricular dysfunction. These results suggest that HIF-PHD inhibitors may be suitable for the treatment of post-MI remodeling and heart failure.
