BACKGROUND A recent landmark report has demonstrated that plasma B-type natriuretic peptide (BNP) measured in acute coronary syndromes independently predicts mortality, heart failure, and new myocardial infarction. After acute cardiac injury, left ventricular ejection fraction (LVEF) is also of prognostic significance and plays a major role in determining the therapeutic response. METHODS AND...

The present study was aimed to investigate the regulatory mechanisms of BNP release. Effects of acute and chronic perturbations in body fluid balance, changes in BP, and regulatory roles of NO and endothelin systems on BNP release were examined in rats. Although acute extracellular volume expansion did not have significant effects on plasma BNP, prolonged high-salt intake increased plasma BNP l...

Although brain natriuretic peptide (BNP) of myocardial origin is important in cardiovascular and renal function and as a marker of cardiac dysfunction, the expression of BNP in atrial and ventricular myocardium remains controversial both under normal conditions and in heart failure. We therefore determined left atrial and left ventricular (LV) gene expression and tissue concentration as well as...

BACKGROUND Hemodynamic and neurohumoral function can affect the efficacy of diuretic therapy in congestive heart failure. Arginine vasopressin increases water reabsorption through the V(2) receptor in the collecting duct, whereas B-type natriuretic peptide (BNP) decreases sodium reabsorption in the collecting duct. We hypothesized that combining BNP to the V(2)-receptor antagonist tolvaptan (TL...

background respiratory distress syndrome (rds) is considered as one of the most popular prematurity-related respiratory problems and among the most prominent reasons of deaths in preterm infants. objectives brain natriuretic peptide (bnp) is the secret of the volume and pressure overload response of the vessels and decreases due to resistance as well as rises in systemic vessels and also in dec...

BACKGROUND Recombinant human B-type natriuretic peptide (rhBNP) has been indicated for the treatment of acute decompensated heart failure (ADHF). However, the therapeutic efficacy of intravenous rhBNP is not always satisfactory in patients with extremely high blood BNP levels. In this study, we evaluated the effects of rhBNP on patients with different BNP levels. METHODS One hundred and five ...

  Background   In respect to abnormalities in thalassemia patients and the effects of TNF_α, IL_6, and NT-pro-BNP on echocardiography findings the study aimed to investigate TNF_α, NT-pro-BNP and IL_6 correlations wit...

OBJECTIVES We wished to examine the effects of age and gender on plasma brain natriuretic peptide (BNP) concentration in a population-based study. BACKGROUND Measurement of BNP concentration is approved for use in the diagnosis of heart failure and may aid in the detection of left ventricular dysfunction. Although BNP is approved for clinical use, there are few data regarding the range of BNP...

B-type natriuretic peptide (BNP) plasma concentrations are raised in patients with heart failure. In several experimental models of cardiac overload, however, BNP mRNA and plasma BNP peptide levels are normal, despite the persistent increase in blood pressure and ventricular hypertrophy. In this study, the role of transcriptional mechanisms in the regulation of BNP gene expression were studied ...

To the Editor:—We read with great interest the research article by Fox et al. on genetic variation within defined regions of the NPPA/NPPB and NPR3 natriuretic peptide system genes as predictors for ventricular dysfunction after coronary artery bypass graft surgery. What concerns us as clinicians is the relation between those biomarkers and postoperative outcome, which can facilitate the preope...
