BACKGROUND Circulating levels of B-type natriuretic peptide (BNP), a cardiac hormone, reflect the severity of cardiac dysfunction. Because the plasma BNP level changes dramatically during the period after the onset of acute myocardial infarction (AMI), identification of a suitable sampling time is problematic. There have been several reports indicating that the plasma BNP level obtained in the ...

BACKGROUND Plasma B-type natriuretic peptide (BNP) is a diagnostic and prognostic marker in heart failure (HF). Although renal function is reported as an important clinical determinant, precise evaluations of the relationships of renal function with hemodynamic factors in determining BNP have not been performed. Therefore, we evaluated the association of plasma BNP concentrations with LV end-di...

The natriuretic peptides are a family of related hormones that play a crucial role in cardiovascular and renal homeostasis. They have recently emerged as potentially important clinical biomarkers in heart failure. Natriuretic peptides, particularly brain natriuretic peptide (BNP) and the inactive N-terminal fragment of BNP, NT-proBNP, that has an even greater half-life than BNP, are elevated in...

1. The major cardiovascular and renal actions of alpha-atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) and the fact that the heart is strategically located to sense changes in intravascular volume indicate the importance of these peptides in the overall control of the extracellular fluid volume under normal and pathophysiological conditions.2. This review examines the clini...

BACKGROUND The aim of the present study was to prospectively study whether a combination of markers for myocardial cell injury and left ventricular overload at admission can reliably risk stratify patients hospitalized for chronic heart failure (CHF). METHODS AND RESULTS Serum concentrations of heart-type fatty acid binding protein (H-FABP) and plasma concentrations of brain natriuretic pepti...

Synthesis and release of B-type natriuretic peptide (BNP) are increased in heart failure, and plasma concentrations provide important therapeutic and prognostic information. Recent studies have shown that BNP concentrations are also increased with disease of the mitral and aortic valves. The extent of the increase is broadly related to the severity of the valve abnormality and the degree of con...

This study sought to determine plasma levels of B-natriuretic peptide (BNP) in patients with light-chain-associated amyloidosis and correlate them with the presence or absence of heart failure (HF) and the presence or absence of echocardiographic abnormalities. Patients with normal echocardiographic results had significantly lower BNP levels than those with echocardiographic features of cardiac...

BACKGROUND Conflict exists regarding the usefulness of measuring plasma B type natriuretic peptide (BNP) concentrations for identifying impaired left ventricular (LV) systolic function during mass screening. Various cardiac abnormalities, regardless of degree of LV dysfunction, are prone to carry a high risk of cardiovascular events. OBJECTIVE To examine the validity of plasma BNP measurement...

BACKGROUND The effect of impaired kidney function on B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) is vague. This study was performed to examine the effect of kidney dysfunction on the afore-mentioned markers and determine appropriate cutoffs for systolic heart failure (SHF). METHODS In this cross sectional study adults with estimated glomerular filtration rate (eGFR) <60...

Atrial natriuretic peptide (ANP) and brain (B-type) natriuretic peptide (BNP) are circulating hormones of cardiac origin that play an important role in the regulation of intravascular blood volume and vascular tone. The plasma concentrations of ANP and BNP are elevated in heart failure, and they are considered to compensate for heart failure because of their diuretic, natriuretic, and vasodilat...
