Reverse Cardiac Remodeling and ARNI Therapy

Abstract

Purpose of Review To review reverse cardiac remodeling and guideline-directed medical and device therapy (GDMT) within the context of recent data on combined angiotensin receptor/neprilysin inhibitor (ARNI) therapy. Recent Findings Preliminary data suggested that ARNI therapy led to significant reversal of deleterious cardiac remodeling. More definitive data regarding impact of ARNI therapy on remodeling parameters are now available from two prospective trials, PROVE-HF (Prospective Study of Biomarkers, Symptom Improvement, and Ventricular Remodeling During Sacubitril/Valsartan Therapy for Heart Failure) and EVALUATE-HF (Study of Effects of Sacubitril/Valsartan vs. Enalapril on Aortic Stiffness in Patients With Mild to Moderate HF With Reduced Ejection Fraction). Both studies demonstrated marked improvements in biomarker and echocardiographic parameters of reverse cardiac remodeling in patients with heart failure with reduced ejection fraction (HFrEF). Summary Much of the observed clinical benefit of sacubitril/valsartan therapy in patients with HFrEF is likely related to significant reverse cardiac remodeling. Ongoing trials will assess the role for ARNI therapy in patients with heart failure with preserved ejection fraction (HFpEF) and in the post-myocardial infarction setting. Future studies should comprehensively assess predictors of response to ARNI therapy.
