New therapeutic strategies aimed to tackle the rising socio-economic burden of heart failure (HF) have become an impelling priority. The new pharmacological class of angiotensin (Ang) receptor-neprilysin inhibitors (ARNI) prompted a real conceptual change in the treatment of HF moving from only the inhibition of the renin-Ang-aldosterone system and sympathetic nervous system to a strategy based on the concomitant pharmacological enhancement of endogenous natriuretic peptides. Sacubitril/valsartan, a first-in-class ARNI, has reduced the primary composite endpoint of cardiovascular death or HF hospitalisation, sudden cardiac death, disease progression and improved quality of life, compared with enalapril, in patients on evidence-based contemporary medical therapy. Our review underlines the increasing body of evidence supporting the efficacy of sacubitril/valsartan, which may be considered a new disease-modifying therapy and, after about 30 years of research, a real step forward in HF pharmacological therapy.
