BACKGROUND Coronary artery disease (CAD) is one of the leading causes of morbidity and mortality in haemodialysis (HD) patients. Although the plasma B-type natriuretic peptide (BNP) levels may be a strong marker of long-term mortality in HD patients, what plasma BNP levels reflect is not well known in this setting. Therefore, we examined the relationship between plasma BNP levels and the presen...

Recent studies have shown that not only plasma B-type natriuretic peptide (BNP)-32, but also plasma proBNP-108 is increased in heart failure (HF), and that the current BNP-32 assay kit crossreacts with proBNP-108. It also was shown that both BNP-32 and proBNP-108 were higher in HF than in normal. The proBNP-108/total BNP (BNP-32 + proBNP-108) ratio was widely distributed and patients with HF wi...

Brain-derived natriuretic peptide (BNP) is a cardioprotective peptide released, together with the inactive NH(2)-terminal part of its prohormone (NT-pro-BNP), in response to different kinds of myocardial stress. Hypoglycemia and hypoxemia are conditions that threaten cellular function and hence potentially stimulate BNP release. BNP interacts with the renin-angiotensin system (RAS). The aim of ...

B-type natriuretic peptide (BNP) has been known to be secreted from cardiac myocytes and activate its receptor, natriuretic peptide receptor-A (NPR-A), to reduce ventricular fibrosis. However, the function of BNP/NPR-A pathway in the somatic sensory system has been unknown. In the present study, we report a novel function of BNP in pain modulation. Using microarray and immunoblot analyses, we f...

AIMS This study investigated the prognostic value of B type natriuretic peptide (BNP) in acute myocardial infarction (AMI) patients and its relation with left ventricular function and post-myocardial infarction complications. METHODS In this cross-sectional study, plasma BNP level was measured for 42 consecutive patients (mean ± SD: 61.6 ± 10.85 years old) with acute ST elevation myocardial i...

Altered myocardial structure and function, secondary to chronically elevated blood pressure, are leading causes of heart failure and death. B-type natriuretic peptide (BNP), a guanylyl cyclase A agonist, is a cardiac hormone integral to cardiovascular regulation. Studies have demonstrated a causal relationship between reduced production or impaired BNP release and the development of human hyper...

This study was designed to explore whether it was possible to evaluate the severity of VSD, PDA, and ASD by measuring brain natriuretic peptide (BNP) levels. We also investigated normal BNP levels in children to provide a baseline for our study. We measured BNP levels in 253 normal children, including 11 normal neonates, and in 91 VSD patients, 29 PDA patients, and 34 ASD patients. BNP levels s...

BACKGROUND In heart failure (HF), ventricular myocardium expresses brain natriuretic peptide (BNP). Despite the association of elevated serum levels with poor prognosis, BNP release is considered beneficial because of its antihypertrophic, vasodilating, and diuretic properties. However, there is evidence that BNP-mediated signaling may adversely influence cardiac remodeling, with further impair...

BACKGROUND There are limited data on the prognostic implications of brain natriuretic peptide (BNP) assessment in patients with mildly symptomatic heart failure (HF) who receive cardiac resynchronization therapy with a defibrillator (CRT-D). METHODS AND RESULTS The effect of elevated baseline and 1-year BNP levels (dichotomized at the upper tertile BNP of 120 pg/mL) on the risk of HF or death...

BACKGROUND  Most patients with surgically corrected tetralogy of Fallot (TOF) are faced with multiple residua and sequelae such as pulmonary regurgitation (PR), resulting in reoperation for pulmonary valve replacement (PVR). Plasma brain natriuretic peptide (BNP) level and serum N-terminal pro-BNP (NT-pro-BNP) level are useful as diagnostic objective markers of chronic heart failure (CHF). The ...
