Brain Natriuretic Peptide (BNP) and N-Terminal-proBNP in Cardio-Renal Anemia Syndrome?- Difference in Prognostic Ability.

ABSTRACT: Background: Cardio-renal anemia syndrome (CRAS) is a growing health problem, with a high mortality rate. Brain natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) are well-established diagnostic and prognostic biomarkers of heart failure (HF). The difference in the clinical significance of these biomarkers, however, has not yet been completely elucidated in HF. The aim of the present study was to compare the prognostic ability of BNP and NT-proBNP in HF patients with CRAS. Methods?and?Results: We measured BNP and NT-proBNP in 492 consecutive HF patients and in 17 control subjects. All patients were prospectively followed up during a median follow-up period of 1,034 days. NT-proBNP/BNP ratio was elevated in HF patients with CRAS compared with those without CRAS and the control subjects. There was no significant difference in the prognostic abilities of BNP and NT-proBNP in all HF patients. The C-index for NT-proBNP for predicting cardiovascular events and mortality, however, was significantly higher than that for BNP in HF patients with CRAS. On multivariate Cox proportional hazards-regression analysis, NT-proBNP, but not BNP, was an independent predictor for clinical outcome in HF with CRAS. Conclusions: The difference in the prognostic abilities of BNP and NT-proBNP was high in HF patients with CRAS. NT-proBNP had a superior prognostic ability to BNP in HF patients with CRAS.

Project description:BackgroundNT-proBNP (N-terminal pro-B-type natriuretic peptide) levels are variably elevated in heart failure with preserved ejection fraction (HFpEF), even in the presence of increased left ventricular filling pressures. NT-proBNP levels are prognostic in HFpEF and have been used as an inclusion criterion for several recent randomized clinical trials. However, the underlying biologic differences between HFpEF participants with high and low NT-proBNP levels remain to be fully understood.MethodsWe measured 4928 proteins using an aptamer-based proteomic assay (SOMAScan) in available plasma samples from 2 cohorts: (1) Participants with HFpEF enrolled in the PHFS (Penn Heart Failure Study; n=253); (2) TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist Trial) participants in the Americas (n=218). We assessed the relationship between SOMAScan-derived plasma NT-proBNP and levels of other proteins available in the SOMAScan assay version 4 using robust linear regression, with correction for multiple comparisons, followed by pathway analysis.ResultsNT-proBNP levels exhibited prominent proteome-wide associations in PHFS and TOPCAT cohorts. Proteins most strongly associated with NT-proBNP in both cohorts included SVEP1 (sushi, von Willebrand factor type-A, epidermal growth factor, and pentraxin domain containing 1; βTOPCAT=0.539; P<0.0001; βPHFS=0.516; P<0.0001) and ANGPT2 (angiopoietin 2; βTOPCAT=0.571; P<0.0001; βPHFS=0.459; P<0.0001). Canonical pathway analysis demonstrated consistent associations with multiple pathways related to fibrosis and inflammation. These included hepatic fibrosis and inhibition of matrix metalloproteases. Analyses using cut points corresponding to estimated quantitative concentrations of 360 pg/mL (and 480 pg/mL in atrial fibrillation) revealed similar proteomic associations.ConclusionsCirculating NT-proBNP levels exhibit prominent proteomic associations in HFpEF. Our findings suggest that higher NT-proBNP levels in HFpEF are a marker of fibrosis and inflammation. These findings will aid the interpretation of NT-proBNP levels in HFpEF and may guide the selection of participants in future HFpEF clinical trials.
