AIMS B-type natriuretic peptide (BNP) and C-reactive protein (CRP) predict atrial fibrillation (AF) risk. However, their risk stratification abilities in the broad community remain uncertain. We sought to improve risk stratification for AF using biomarker information. METHODS AND RESULTS We ascertained AF incidence in 18 556 Whites and African Americans from the Atherosclerosis Risk in Commun...
BACKGROUND Plasma brain natriuretic peptide (BNP) level increases in proportion to the degree of right ventricular dysfunction in pulmonary hypertension. We sought to assess the prognostic significance of plasma BNP in patients with primary pulmonary hypertension. METHODS AND RESULTS Plasma BNP was measured in 60 patients with primary pulmonary hypertension at diagnostic catheterization, toge...
Atrial natriuretic peptide (ANP) secretion increases after 30 min of paroxysmal supraventricular tachycardia (PSVT). Whether this phenomenon also applies to brain or C-type natriuretic peptides (BNP or CNP) remains unknown. Blood samples of 18 patients (41 ± 11 yr old; 4 men) with symptomatic PSVT and normal left ventricular systolic function (ejection fraction 65 ± 6%) were collected from the ...
There are many established and proposed bio-molecular markers for cardiovascular disease, including vasoactive substances, substances related to inflammation and oxidative stress, and substances involved in tissue structure and remodeling. Among these substances, we focused on natriuretic peptides and adrenomedullin (AM) as clinically useful bio-molecular markers in this review. Three natriuret...
BACKGROUND A recent study by Mishra and Hoon identified B-type natriuretic peptide (BNP) as an important peptide for itch transmission and proposed that BNP activates spinal natriuretic peptide receptor-A (NPRA) expressing neurons, which release gastrin releasing peptide (GRP) to activate GRP receptor (GRPR) expressing neurons to relay itch information from the periphery to the brain (Science 3...
OBJECTIVES The aim of this study was to determine the effect of transient myocardial ischemia on circulating natriuretic peptide levels. BACKGROUND Natriuretic peptides are released by the heart in response to wall stress. We hypothesized that transient myocardial ischemia would cause acute changes in circulating natriuretic peptide levels. METHODS B-type natriuretic peptide (BNP), N-termin...
Brain natriuretic peptide (BNP) is a cardiac hormone secreted predominantly from the ventricles. This hormone is produced as pre-prohormone BNP (pro BNP), than cleaved by corine to biologically active 32-aminoacid BNP and non-biologically active N-terminal-pro brain natriuretic peptide (NTproBNP). NTproBNP has been found to be a useful marker for the diagnosis of heart failure and left ventricu...
INTRODUCTION AND OBJECTIVES The aim of the present study was to document the evolution of the blood levels of brain natriuretic peptide (BNP) in patients with heart failure and their correlation with the clinical course after implantation of a biventricular pacemaker. PATIENTS AND METHOD Twenty-eight patients with heart failure associated to left bundle branch block and left ventricular systo...
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...
BACKGROUND Corin, a transmembrane serine protease expressed in cardiomyocytes, cleaves pro-atrial natriuretic peptide and pro-brain natriuretic peptide (BNP) into biologically active peptide hormones. The minor corin I555(P568) allele, defined by the T555I and Q568P mutations, is common in persons of African ancestry and associated with increased risk for hypertension and cardiac concentric hyp...
