The aim of the present study was to assess the utility of amino-terminal pro-A-type natriuretic peptide (NT-proANP) measurements for the emergency diagnosis of acute destabilized heart failure (HF), using a novel sandwich immunoassay covering midregional epitopes (MR-proANP). ⋯ MR-proANP measurements may be useful as an aid in the diagnosis of acute destabilized HF in short-of-breath patients presenting to an emergency department. The diagnostic value of MR-proANP appears to be comparable to that of BNP and NT-proBNP.
