: Studies have suggested roles for angiopoietin-2 (Ang-2) and soluble P-selectin (sP-selectin) as biomarkers of disease severity and treatment response in pulmonary arterial hypertension (PAH), but additional data are required for validation. We evaluated these biomarkers using data from FREEDOM-C2, in which patients with PAH receiving stable monotherapy or combination therapy were randomized to receive additional treatment with oral treprostinil (up-titrated from 0.25 mg twice daily) or placebo for 16 weeks...

BACKGROUND: Higher N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels have been linked to a more favorable glucometabolic profile. Little is known about the interaction of NT-proBNP and fasting glucose in non-ST-segment elevation acute coronary syndrome (NSTE ACS). METHODS: Fasting glucose and NT-proBNP were measured in 2240 patients enrolled in the EARLY ACS trial. Multivariable Cox models were used to assess associations between fasting glucose and NT-proBNP and a 96-hour composite of death, myocardial infarction (MI), recurrent ischemia, or thrombotic bailout; 30-day death or MI; and 1-year mortality...

OBJECTIVE: Vasoactive cardiovascular hormones such as the N-terminal prohormone of brain natriuretic peptide (NT-proBNP) are produced upon ventricular stretch and play a central role in neurohumoral pathways of the heart regulating cardiovascular remodeling and volume homeostasis. The impact of HIV infection on these neurohumoral pathways of the heart and its potential reversibility by combinations of antiretroviral therapies remain unclear. METHODS: We assessed serum levels of NT-proBNP in 219 antiretroviral therapy-naïve HIV-infected patients with a normal cardiac and renal status at treatment initiation and after attainment of viremic control...

Remodelling in the atria could appear as a result of hypertension, diabetes or ischaemic heart disease. Galectin-3 (Gal-3) is a mediator of profibrotic pathways and a potential biomarker of cardiac remodelling. We prospectively recruited consecutive patients undergoing elective cardiac surgery. Preoperative Gal-3 levels were determined from serum samples, and the presence of fibrosis was assessed from atrial appendage tissue samples obtained during cardiac surgery. We included 100 patients with aortic valve or ischaemic heart diseases and 15 controls with permanent AF...

BACKGROUND: Mid-regional pro-adrenomedullin (MR-proADM) is a surrogate marker for adrenomedullin; a hormone that attenuates myocardial remodeling. Accordingly, we hypothesized that MR-proADM could provide diagnostic and prognostic information in patients with acute dyspnea. METHODS AND RESULTS: We measured MR-proADM by a commercial ELISA on hospital admission in 311 patients with acute dyspnea and compared the utility of MR-proADM with N-terminal pro-B-type natriuretic peptide (NT-proBNP)...

BACKGROUND: Soluble CD146 (sCD146), is an endothelial marker with similar diagnostic power as natriuretic peptides in decompensated heart failure (HF). While natriuretic peptides are released by the failing heart, sCD146 may be released by veins in response to stretch induced by systemic congestion in HF. This study investigated the source, effects of vascular stress on release and prognostic properties of sCD146 in HF. METHODS: In a peripheral venous stress study, plasma concentrations of sCD146 and N-terminal probrain natriuretic-peptide (NT-proBNP) were measured in 44 HF patients at baseline and after 90 min of unilateral forearm venous congestion...

BACKGROUND: Currently, N-terminal pro-B-type natriuretic peptide (NT-proBNP) and its physiologically active counterpart, BNP, are most frequently used as biomarkers for diagnosis, prognosis, and disease monitoring of heart failure (HF). Commercial NT-proBNP and BNP immunoassays cross-react to varying degrees with unprocessed proBNP, which is also found in the circulation. ProBNP processing and immunoassay response are related to O-linked glycosylation of NT-proBNP and proBNP. There is a clear and urgent need to identify the glycosylation sites in the endogenously circulating peptides requested by the community to gain further insights into the different naturally occurring forms...

BACKGROUND: B-type natriuretic peptides (BNPs) are used clinically to diagnose and monitor heart failure and are present in the circulation as multiple proBNP-derived fragments. We investigated the specificity of BNP immunoassays with glycosylated and nonglycosylated BNP, N-terminal proBNP (NT-proBNP), and proBNP peptides to probe the cross-reactivity of each assay. METHODS: Nine B-type natriuretic peptides were studied,including synthetic and recombinant BNP (Shionogi, Scios, Mayo), human and synthetic glycosylated and nonglycosylated NT-proBNP (HyTest, Roche Diagnostics), and human glycosylated and nonglycosylated proBNP (HyTest, Scios)...

AIMS: C-type natriuretic peptide (CNP) is a paracrine growth factor expressed in the vascular endothelium. Although upregulated in atheromatous arteries, the predictive value of plasma CNP products for outcome in coronary disease is unknown. This study aimed to compare the prognostic value of plasma CNP products with those of other natriuretic peptides in individuals with coronary artery disease, and investigate their associations with cardiac and renal function. METHODS AND RESULTS: Plasma concentrations of CNP and amino-terminal proCNP (NT-proCNP) were measured at baseline in 2129 individuals after an index acute coronary syndrome admission and related to cardiac and renal function, other natriuretic peptides [atrial NP (ANP) and B-type NP (BNP)] and prognosis (primary end point, mortality; secondary end point, cardiac readmission)...

Yang Chen, John C Burnett
BACKGROUND: Neprilysin (NEP) is a membrane-bound neutral endopeptidase that degrades a variety of bioactive peptides. The substrates include natriuretic peptides (NPs), which are important regulating mediators for cardiovascular and renal biology. Inhibition of NEP activity and exogenous NP administration thus have emerged as potential therapeutic strategies for treating cardiorenal diseases. More recently, B-type natriuretic peptide (BNP) or N-terminal-proBNP (NT-proBNP), 3'-5' cyclic guanosine monophosphate (cGMP), and soluble NEP as biomarkers have also been investigated in heart failure (HF) trials and their predictive value are beginning to be recognized...
