An accurate diagnosis is important because heart failure can be successfully managed with various medical treatments.Higher levels of BNP or NT-proBNP also may be associated with a worse outlook ( prognosis) for the patient.

It is, however, unknown whether BNP and NT-proBNP differ in their utility to risk-stratify patients with ADHF. Also, little is known regarding the earliest time point for reliable assessment of treatment efficacy and prognosis.BNP and NT-proBNP could not reliably predict heart failure readmission. Higher levels of BNP or NT-proBNP are often associated with a worse outlook ( prognosis) for the person.Roche Receives FDA Clearance for Elecsys proBNP Assay First Automated Blood Test to Aid in the Diagnosis of Congestive Heart Failure (2002).

B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) are promising markers for heart failure diagnosis, prognosis, and treatment.1,2 This systematic review addresses these four main questions Databases were searched from 1989 to February 2005 for primary studies that measured BNP or NT-proBNP for the purpose of diagnosis, prognosis and monitoring treatment.To determine the screening and diagnostic properties of BNP and NT-proBNP for heart failure in primary care. These studies are just a few to point to the exceptional value of NT- proBNP for the diagnosis, prognosis, and management of patients with HF.

Beyond their ability to diagnose HF when markedly elevated, both BNP and NT-proBNP are also useful to exclude the diagnosis when very low.Serial measurement in chronic HF patients also strongly predict prognosis. In the Valsartan Heart Failure Trial (Val-HeFT) study,14 a four-month When used in the evaluation of patients with acute symptoms, brain natriuretic peptide and N-terminal pro-brain natriuretic peptide ( BNP and NT-proBNP, respectively) testing is highly sensitive for the diagnosis or exclusion of acute or chronic decompensated heart failure (HF). B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) are promising markers for heart failure diagnosis, prognosis, and treatment. Heart Failure: Biomarkers of Diagnosis and Prognosis. OCTOBER 2010. Both NT-proBNP and BNP can be measured rapidly enough to provide clinically useful information in the ED setting. Even though BNP and NT-proBNP are secreted in equimolar quantities, the circulating concentration of these two markers is significantly different, particularly in patients with heart failure and compromised renal function.

Clin Chem Lab Med 39(7): 571-88. Background: Heart failure (HF) is one of the most frequent cardiovascular diseases in the Western countries. Its prevalence in Europe varies from 0.4 to 2. The aim of the study was to compare the performances of BNP (Biosite) and NT-proBNP(Roche) for diagnosing heart failure (HF) in a Prognosis. See also the separate Heart Failure Management, Cardiac Rehabilitation and Palliative Care of Heart Failure articles.If natriuretic peptide levels are normal (BNP level less than 100 pg/mL (29 pmol/L) or NT-proBNP less than 400 pg/mL (47 pmol/L)), a diagnosis of heart failure is unlikely. Heart failure (HF) biomarkers have dramatically impacted the way HF patients are evaluated and managed. B-type natriuretic peptide ( BNP) and N-terminal proBNP (NT-proBNP) are the gold standard biomarkers in determining the diagnosis and prognosis of HF, and studies on natriuretic In addition, the elevated plasma concentrations of BNP and NT-proBNP are a prognostic marker of morbidity, mortality and later development of heartThis review summarizes recently known facts about the role of BNP in the diagnosis, management and prognosis of congestive heart failure BNP and NT-proBNP levels can help doctors differentiate between heart failure and other problems, such as lung disease.Higher levels of BNP or NT-proBNP are often associated with a worse outlook ( prognosis) for the person.
