BACKGROUND Plasma B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) are promising markers for heart failure diagnosis, prognosis, and treatment. Insufficient data on the intraindividual biological variation (CV(i)) of BNP and NT-proBNP hamper interpretation of changes in concentration on disease progression or treatment optimization. We therefore investigated CV(i) values in st...
Circulating levels of B-type natriuretic peptide (BNP) and NH(2)-terminal-proBNP (NT-proBNP) increase in response to volume overload and help in the differential diagnosis of acute heart failure. Elevated plasma BNP levels are observed also in sepsis and do not always correspond to left ventricular dysfunction. Here, we investigated plasma NT-proBNP fluctuations in response to human bacterial e...
BACKGROUND Urine amino-terminal probrain natriuretic peptide (NT-proBNP) concentrations may exclude the presence of heart failure and provide insight into renal clearance mechanisms for human NT-proBNP. We characterized the molecular forms of urine NT-proBNP detected by immunoassay. METHODS Urine from patients with heart failure was subjected to HPLC and analyzed using immunoassays specific t...
OBJECTIVES The aim of this research was to describe N-terminal part of the pro-B-type natriuretic peptide (NT-proBNP) levels over time in non–ST-segment elevation acute coronary syndromes (NSTEACS), to elucidate factors associated with changes of NT-proBNP levels, and to examine association with long-term mortality. BACKGROUND The NT-proBNP levels are associated with mortality. Long-term tempor...
BACKGROUND In heart failure with mid-range ejection fraction (HFmrEF) and preserved ejection fraction (HFpEF), feasible surrogate end points are needed for phase II trials. The aim was to assess whether a reduction in N-terminal pro-B-type natriuretic peptide (NT-proBNP) is associated with improved mortality/morbidity in an unselected population of HFmrEF and HFpEF patients. METHODS AND RESUL...
BACKGROUND Higher body mass index (BMI) is associated with lower circulating levels of N-terminal-pro-b-type natriuretic peptide (NT-proBNP). The Interaction between BMI and NT-proBNP with respect to clinical outcomes is not well characterized in patients with acute heart failure. METHODS AND RESULTS A total of 686 patients from the biomarker substudy of the ASCEND-HF (Acute Study of Clinical...
AIMS To assess the role of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in the diagnosis of major structural heart disease (MSHD) in patients with atrial fibrillation (AF) compared with those with sinus rhythm (SR) using receiver operator characteristic (ROC) analysis. NT-proBNP is elevated in MSHD and heart failure (HF). AF, a common finding in HF and MSHD, is also associated with rai...
OBJECTIVE To determine the potential role of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in screening for and predicting prognosis in heart failure by examining diagnosis and survival of patients with a raised NT-proBNP at screening. DESIGN Survival analysis. SETTING Prospective substudy of the Echocardiographic Heart of England Screening study (ECHOES) to investigate 10-year surv...
BACKGROUND Amino-terminal pro-B type natriuretic peptide (NT-proBNP) is a well-established prognostic factor in heart failure (HF). However, numerous causes may lead to elevations in NT-proBNP, and thus, an increased NT-proBNP level alone is not sufficient to predict outcome. The aim of this study was to evaluate the utility of two acute response markers, high sensitivity C-reactive protein (hs...
OBJECTIVES The aim of this study was to evaluate whether chronic heart failure (HF) therapy guided by concentrations of amino-terminal pro-B-type natriuretic peptide (NT-proBNP) is superior to standard of care (SOC) management. BACKGROUND It is unclear whether standard HF treatment plus a goal of reducing NT-proBNP concentrations improves outcomes compared with standard management alone. ME...
