Prognostic Value and Kinetics of Soluble Neprilysin in Acute Heart Failure

Abstract Objectives This study sought to examine the prognostic value of the soluble form of neprilysin (sNEP) in acute heart failure (AHF) and sNEP kinetics during hospital admission. Background sNEP was recently identified in chronic heart failure (HF) and was associated with cardiovascular outcomes. Methods A total of 350 patients (53% women, mean 72.6 ± 10.7 years of age) were included in the study. Primary endpoints were composites of cardiovascular death or HF hospitalizations at short-term (2 months) and long-term (mean: 1.8 ± 1.2 years) follow-up. sNEP was measured using an ad hoc–modified enzyme-linked immunosorbent assay, and its prognostic value was assessed using Cox regression …
