Aims The aim of this study was to assess diagnostic and prognostic value of mid-regional pro-atrial natriuretic peptide (MR-proANP) and adrenomedullin (MR-proADM) for the evaluation of patients presenting to the emergency department with acute dyspnoea. Methods and results A total of 560 patients from the pro-B type natriuretic peptide Investigation of Dyspnoea in the Emergency Department were evaluated; 180 had acutely decompensated heart failure (ADHF). Concentrations of amino-terminal pro-B type natriuretic peptide (NT-proBNP), MR-proADM, and MR-proANP were measured, and patients were followed to 4 years for survival. Logistic regression evaluated utility of MR-proANP in ADHF diagnosis. Area under the curve (AUC), multivariate Cox regression, net reclassification improvement, and Kaplan-Meier survival analyses were used for mortality analyses. Mid-regional pro-atrial natriuretic peptide was higher in patients with ADHF (median 329 vs. 58 pmol/L; P < 0.001), and remained an independent predictor of HF diagnosis even when NT-proBNP was included as a covariate (odds ratio = 4.34, 95% CI = 2.11-8.92; P < 0.001). In time-dependent analyses, MR-proADM had the highest AUC for death during the first year; after 1 year, MR-proANP and NT-proBNP had a higher AUC. Both mid-regional peptides were independently prognostic and reclassified risk at 1 year [MR-proANP, hazard ratio (HR) = 2.99, MR-proADM, HR = 2.70; both P < 0.001] and at 4 years (MR-proANP, HR = 3.12, P < 0.001; MR-proADM, HR = 1.51, P = 0.03) and in Kaplan-Meier curves both mid-regional peptides were associated with death out to 4 years, individually or in a multimarker strategy. Conclusion Among patients with acute dyspnoea, MR-proANP is accurate for diagnosis of ADHF, while both MR-proANP and MR-proADM are independently prognostic to 4 years of the follow-up.
