Angiotensin receptor-neprilysin inhibitors: A new paradigm in heart failure with reduced ejection fraction

Abstract

Despite significant advances in the last 30 years in reducing morbidity and mortality from heart failure with reduced ejection fraction (HFrEF) with pharmacological and device-based therapies, patients remain at a high risk of adverse cardiovascular outcomes. Sacubitril/valsartan, a first-in-class angiotensin receptor-neprilysin inhibitors (ARNI), has been shown to reduce the risk of cardiovascular death or heart failure hospitalisation and improve symptoms in patients with chronic, ambulatory, symptomatic HFrEF in a large, phase 3, multicentre, international, randomised controlled trial, PARADIGM-HF, when compared to the gold-standard angiotensin converting enzyme inhibitor, enalapril. This article will review the development of sacubitril/valsartan, the evidence for its use and its current and future role in the management of HFrEF.
