Background Pro-B-Type Natriuretic Peptide (ProBNP), from which biologically active BNP and inactive amino-terminal BNP (NT-proBNP) are processed, has recently been reported to be elevated in patients with heart failure (HF). It remains to be shown in a large cohort study whether ProBNP circulates in normals, what factors influence ProBNP, and whether or not it is a sensitive biomarker for left ...
OBJECTIVE Intensive medical treatment of heart failure (HF) patients with diabetes may reduce the endothelial dysfunction and the accelerated atherosclerotic process seen in these patients. To study this, we investigated the endothelial function and the presence of atherosclerosis as measured by flow-mediated vasodilatation (FMD) and intima-media thickness (IMT) in intensively treated patients ...
BACKGROUND Natriuretic peptides have been proposed as biomarkers of cardiovascular disease, especially heart failure. Brain natriuretic peptide (BNP) has also been shown to be upregulated at the transcriptional and translational levels by pro-inflammatory cytokines in cardiac myocytes. Although we often measure plasma BNP levels in cancer patients, it remains unknown whether cancer-related infl...
BACKGROUND The B-type natriuretic peptides (BNP and N-terminal pro-BNP) are secreted by the heart and, in the case of BNP, serve to maintain circulatory homeostasis through renal and vascular actions and oppose many effects of the renin-angiotensin system. Recent evidence suggests that in patients with severe heart failure, circulating immunoreactive BNP is made up mainly of metabolites that ma...
OBJECTIVES This study sought to compare the renal clearance mechanisms of B-type natriuretic peptide (BNP) and amino terminal pro-B-type natriuretic peptide (NT-proBNP). BACKGROUND The small molecular weight proteins (SMWPs) BNP and NT-proBNP both inversely correlate with glomerular filtration rate (GFR). Whether this association is causal or confounding is unknown and has been the basis of w...
The natriuretic peptide family consists of a number of structurally homologous but genetically distinct polypeptide mediators. The peptides are highly conserved across mammalian and invertebrate species and, in humans, are released from various tissues in response to physiological and pathological stimuli. All the peptides have at their core a 17-amino acid disulfide ring essential for receptor...
BACKGROUND Doppler echocardiographic studies of the left ventricle (LV) function in patients with β-Thalassemia Major (β-TM) had shown different patterns of systolic and diastolic dysfunctions associated with abnormal serum brain natriuretic peptide (BNP). AIM This cross-sectional study was designed to study the LV systolic and diastolic functions and correlate that with serum level of N-term...
A large number of experimental studies have suggested that hypoxia may be a potent stimulus for the myocardial synthesis and release of Atype natriuretic peptide (ANP) and B-type natriuretic peptide (BNP) [1]. However, these studieshaveevaluatedeither theeffectofhypoxiaonANP and/orBNPproduction in isolated cardiomyocytes [2,3], isolatedperfused hearts [4,5], or animals [5,6], or on the circulat...
Background: Dyspnoeic in the emergency department with multiple co-morbidities is a diagnostic challenge. Approximately 15-20% of acute dyspneic Emergency Department due to ADHF (acute decompensated heart failure) are misdiagnosed. B-type peptide (BNP) and its amino-terminal fragment (NT-proBNP) accurately identify HF dyspnoeic patients. In general population dyspnoea, plasma pro-BNP concentrat...
