OBJECTIVE To determine whether the plasma concentration of the putative new cardiac hormone relaxin is predictive of clinical outcome in patients with chronic heart failure (CHF). DESIGN Plasma relaxin and N-terminal pro B type natriuretic peptide (NT pro BNP) concentrations were measured in 87 patients admitted in an emergency with CHF caused by left ventricular systolic dysfunction. These w...

OBJECTIVE Chronic kidney disease is associated with decreased bone mineral density (BMD). In this study, the relationship between BMD and the fasting serum concentration of N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) was evaluated in peritoneal dialysis (PD) patients. MATERIAL AND METHODS Fasting blood samples were obtained from 52 PD patients. BMD was measured by dual energy X-ray...

pulmonary hypertension (ph) is an important cause of heart failure in chronic obstructive pulmonary disease (copd). the pro brain natriuretic peptide n-terminal (nt-probnp) has been suggested as a noninvasive marker to evaluate ventricular function. however, there is no evidence to support the use of nt-probnp in monitoring the benefits of vasodilators in copd induced ph. thus, we used nt-probn...

The polypeptide relaxin (RLX) has been suggested to play a role in cardiorenal integration and to be related to the natriuretic peptide system. We hence examined the effects of variations in thoracic blood volume and intravenous volume loading on plasma and urinary RLX levels and associated changes in natriuretic peptide levels in healthy men. Two groups of eight subjects were randomly tilted i...

BACKGROUND Plasma concentrations of natriuretic peptides are often elevated in chronic hemodialysis patients and difficult to interpret due to accumulation, high incidence of cardiac disease and changes in volume status. Mid-regional pro-ANP is a newly developed assay whereas BNP and its fragment NT-pro-BNP are available for a longer time. In this cross-sectional study, we compared the plasma c...

AIMS The purpose of this study was to evaluate whether yoga training in addition to standard medical therapy can improve cardiac function and reduce N terminal pro B-type natriuretic peptide (NT pro BNP) in heart failure (HF). METHODS 130 patients were recruited and randomized into two groups: Control Group (CG) (n = 65), Yoga Group (YG). In YG, 44 patients and in CG, 48 patients completed th...

the aim of the study was to evaluate the clinical usefulness of n-terminal pro-brain natriuretic peptide (nt-pro bnp) and nitric oxide (no) with echocardiography (gold standard test) in diagnosis of canine cardiomyopathy. out of 374 cases, 82 cases showing cardiovascular abnormalities including 16 cases of cardiomyopathy were further selected for standardization of biomarkers. significant (p

Recent studies support the speculation that different molecular forms of the cardiac hormone BNP with differential biological activity may circulate in heart failure and be detected by conventional assays. In the current study we determined the ability of 3 widely used conventional assays to detect these different forms thought to circulate in heart failure. We also evaluated the ability of pro...

To The Editor: I read the article published in your journal with great interest.1 However, I would like to offer some comments and seek some clarifications on this study. First, whether the study was prospective or retrospective in nature and what was the study duration. Secondly, N-terminal-pro-brain natriuretic peptide (NT-pro-BNP) assay was done before or after confirmation of thrombi by hel...

BACKGROUND Cardiac resynchronization therapy (CRT) improves left ventricular (LV) volumes, mitral regurgitation (MR) severity and symptoms of patients with heart failure (HF). However, >or= 30% of patients have no significant clinical or echocardiographic improvement following CRT. Reverse remodeling after CRT correlates with improved clinical outcomes. We hypothesized that in NT-pro BNP monito...
