OBJECTIVE To analyze the relationship between N-terminal pro-brain natriuretic peptide (NT-proBNP) and renal function, and compare the ability and cut-off thresholds of NT-proBNP to detect chronic heart failure (CHF) and predict mortality in elderly Chinese coronary artery disease (CAD) patients with and without chronic kidney disease (CKD). METHODS The study included 999 CAD patients older t...

OBJECTIVE N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a marker of cardiac dysfunction and has been linked to various indices of large vessel disease. However, it remains unclear whether NT-proBNP also relates to microvascular damage. In a community-dwelling population, we studied the association between NT-proBNP and retinal microvascular damage. APPROACH AND RESULTS From the pop...

BACKGROUND B-type natriuretic peptide (BNP) is produced as a biologically inactive prohormone (proBNP(1-108)), processed, and released as an inactive amino acid N-terminal fragment (proBNP(1-76)) and a biologically active carboxyl-terminal fragment (proBNP(77-108) or BNP32). We hypothesized that simultaneous assessment of proBNP(1-108) and active BNP32, as an index of natriuretic peptide proces...

INTRODUCTION The performance of N-terminal pro-brain natriuretic peptide (NT-proBNP) and C-reactive protein (CRP) to predict clinical outcomes in ICU patients is unimpressive. We aimed to assess the prognostic value of NT-proBNP, CRP or the combination of both in unselected medical ICU patients. METHODS A total of 576 consecutive patients were screened for eligibility and followed up during t...

Background Pro-B-Type Natriuretic Peptide (ProBNP), from which biologically active BNP and inactive amino-terminal BNP (NT-proBNP) are processed, has recently been reported to be elevated in patients with heart failure (HF). It remains to be shown in a large cohort study whether ProBNP circulates in normals, what factors influence ProBNP, and whether or not it is a sensitive biomarker for left ...

We have recently identified a novel amino-terminal fragment of pro-brain natriuretic peptide (NT-proBNP) in the circulation of humans, the concentration of which increases progressively as the left ventricle fails. To clarify the origins of NT-proBNP in experimental animals, we have developed an RIA for NT-proBNP based on residues 52-71 of ovine proBNP-(1-103) and used it to study cardiac proce...

N-terminal pro B-type natriuretic peptide (NT-proBNP) is a product of cleavage of the cardiac prohormone pro B-type natriuretic peptide into its active form. It has proven to be a useful biomarker in left heart failure. However, studies examining the utility of serial measurements of NT-proBNP in pulmonary arterial hypertension (PAH) patients have shown mixed results. We compared three methods ...

Cardiovascular diseases such as acute myocardial infarction and heart failure accounted for the death of 17.5 million people (31% of all global deaths) in 2015. Monitoring the level of circulating N-terminal proBNP (NT-proBNP) is crucial for the detection of people at risk of heart failure. In this article, we describe a novel ultra-sensitive NT-proBNP test (us-NT-proBNP) that allows the quanti...

PURPOSE NT-proBNP has emerged as a powerful diagnostic and prognostic biomarker in heart disease. Studies showed that NT-proBNP is a sensitive biomarker for identifying patients with heart failure caused by hepatitis C virus (HCV) related myocarditis. The purpose of this study was to evaluate the correlation between the serum concentration of NT-proBNP and hepatitis virus infection/liver diseas...

BACKGROUND Cross-sectional studies have shown that B-type natriuretic peptide (BNP) and its N-terminal fragment (NT-proBNP) are predictive of cardiovascular death in haemodialysis (HD) patients. In the present study, we tested the hypothesis that monitoring NT-proBNP measurements adds further prognostic information, i.e. predicts congestive heart failure (CHF) events. METHODS In a prospective...
