BACKGROUND Natriuretic peptides (NP) have prognostic value in heart failure (HF), although the clinical importance of changes in NP from baseline is unclear. OBJECTIVES The authors assessed whether a reduction in N-terminal pro-B-type NP (NT-proBNP) was associated with a decrease in HF hospitalization and cardiovascular mortality (primary endpoint) in patients with HF and reduced ejection fra...

BACKGROUND Whether body composition is associated with the N-terminal pro-B-type natriuretic peptide (NT-proBNP) level and its prognostic performance in acute coronary syndrome (ACS) remains unknown. We aimed to investigate the influence of body composition on the NT-proBNP level and its prognostic performance among ACS patients. METHODS In total, 1623 ACS patients with NT-proBNP data were en...

BACKGROUND N-terminal pro-brain-type natriuretic peptide (NT-proBNP) is currently used as a surrogate marker for disease severity in pulmonary hypertension (PH). However, NT-proBNP tends to have a high variability and may insufficiently correlate with hemodynamics and exercise capacity. METHODS To investigate the association of NT-proBNP with hemodynamics and cardio-pulmonary exercise testing...

BACKGROUND Bronchopulmonary dysplasia (BPD) is a serious complication of preterm birth. Plasma N-terminal pro-B type natriuretic peptide (NT-proBNP) has been suggested as a marker that may predict BPD within a few days after birth. OBJECTIVES To investigate the association between NT-proBNP day three and bronchopulmonary dysplasia (BPD) or death and further to assess the impact of patent duct...

OBJECTIVES The aim of this study was to assess the relationship between sex hormones and natriuretic peptide levels in community-based adults. BACKGROUND Women have higher circulating natriuretic peptide concentrations than men, but the mechanisms for these sex-related differences and the impact of hormone therapy are unclear. Experimental studies suggest that androgens may suppress natriuret...

The association between severity of heart disease and serum N-terminal prohormone B-type natriuretic peptide (NT-proBNP) was determined in dogs presented with respiratory distress. Four groups of dogs were divided into healthy control (n=11), heart failure (n=58), heart disease without heart failure (n=17) and respiratory disease (n=20). Serum NT-proBNP concentrations were measured with an ELIS...

BACKGROUND Persistent atrial fibrillation (AF) leads to electrical, structural and neurohormonal remodelling of the atria, including increased plasma B-type natriuretic peptide (BNP) level. AIM To assess the clinical value of plasma BNP or NT-proBNP concentrations in patients with persistent AF measured before and after sinus rhythm restoration following direct-current cardioversion. METHOD...

BACKGROUND Plasma levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP) provide useful prognostic predictors in patients after cardiac surgery. However, predictive accuracy of NT-proBNP levels has varied significantly according to renal dysfunction. The purpose of this study was to assess whether preoperative NT-proBNP levels could be used as predictors of early postoperative outcomes...

BACKGROUND Previous studies comparing children with cardiac disease with children with lung disease or healthy children indicated that natriuretic peptides are promising markers in pediatric patients. The aim of this study was to further clarify the diagnostic usefulness of N-terminal pro-B-type natriuretic peptide (NT-proBNP) measurements in a less preselected population of children younger th...

We aimed to evaluate levels of amino-terminal pro-brain natriuretic peptid (NT-proBNP) in prediction of left ventricular ejection fraction (LVEF) in heart failure patients. Prospective study on 60 consecutive patients with symptoms and signs of heart failure was performed. Blood samples for NT-proBNP analysis was taken from all test subjects and echocardiography was also done in all of them. Ac...
