Natriuretic peptides were discovered in 50-70s of the XX century. BNP was more diagnostically and prognostically significant, as it is secreted directly into the ventricles of the heart. The studies demonstrated a high predictive value of increasing the level of BNP in acute decompensation of heart failure and in patients with chronic heart failure in a study of Val-HeFT It was demonstrated tha...

AIMS The Cardiac Resynchronization-Heart Failure (CARE-HF) study demonstrated that cardiac resynchronization therapy (CRT) could reduce morbidity and mortality and improve cardiac function in patients with moderate or severe heart failure secondary to left ventricular systolic dysfunction and markers of cardiac dyssynchrony. The purpose of this analysis was to investigate the effect of CRT on p...

The plasma concentrations of natriuretic peptides, BNP and NTproBNP, have been shown to be markers for the diagnosis of congestive heart failure (CHF). In this study, plasma BNP and NTproBNP concentrations were evaluated and stratified according to renal function, body mass index (BMI), and New York Heart Association (NYHA) classification. Comparison studies between the 2 natriuretic peptide ma...

BACKGROUND Diagnosing heart failure and left ventricular systolic dysfunction is difficult on clinical grounds alone. We sought to determine the accuracy of a heart failure register in a single primary care practice, and to examine the usefulness of b-type (or brain) natriuretic peptide (BNP) assay for this purpose. METHODS A register validation audit in a single general practice in the UK wa...

Mild heart failure is characterized by increases in atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) in the absence of activation of the renin-angiotensin-aldosterone system (RAAS). Vasopeptidase (VP) inhibitors are novel molecules that coinhibit neutral endopeptidase 24.11, which degrades the natriuretic peptides (NPs) and ACE. In a well-characterized canine model of mild h...

BACKGROUND Brain natriuretic peptide (BNP) has been widely used for the diagnosis and prognostic evaluation of chronic heart failure (CHF). In the present study, we performed association study of single nucleotide polymorphisms (SNPs) surrounding the natriuretic peptide precursor B (NPPB) gene with plasma BNP levels in 2970 adult Japanese. METHODS AND RESULTS Association analysis between SNPs...

Using a specific radioimmunoassay for human brain natriuretic peptide (hBNP) with a monoclonal antibody, we have investigated its synthesis, secretion, and clearance in comparison with those of atrial natriuretic peptide (ANP) in normal subjects and patients with congestive heart failure (CHF). Mean BNP-like immunoreactivity (-LI) levels in normal atrium and ventricle were 250 and 18 pmol/g, re...

OBJECTIVE To determine the association between plasma brain natriuretic peptide (BNP) level in patients with heart failure (HF) and physical frailty as well as with each domain of physical frailty. METHODS Two hundred and six outpatients of cardiovascular medicine aged 60 years and older who had been hospitalized for HF or had been given a prescription medication for HF were included. Physica...

BACKGROUND Heterogeneity in B-type natriuretic peptide (BNP) levels, especially among individuals with acute heart failure with normal left ventricular ejection fraction (HFNEF), can cause confusion in interpreting results. We investigated the characteristics of cases of acute HFNEF with only modestly elevated BNP. METHODS One hundred forty-two patients with acute or acute exacerbation of chr...

Both atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) are involved in sodium and water homoeostasis in healthy humans. The plasma concentrations of the natriuretic peptides can be used to differentiate between dyspnoea of cardiac and pulmonary origin, and the degree of elevation of the peptide levels in the plasma in heart failure is a measure of the severity of the disease....
