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...

OBJECTIVE To determine the potential role of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in screening for and predicting prognosis in heart failure by examining diagnosis and survival of patients with a raised NT-proBNP at screening. DESIGN Survival analysis. SETTING Prospective substudy of the Echocardiographic Heart of England Screening study (ECHOES) to investigate 10-year surv...

BACKGROUND The variability of NT-proBNP levels has been studied in heart failure, yet no data exist on these changes over time in hypertensive patients. Furthermore, studies on the relationship between natriuretic peptides and inflammatory status are limited. METHODOLOGY/PRINCIPAL FINDINGS 220 clinically and functionally asymptomatic stable patients (age 59 ± 13, 120 male) out of 252 patients...

a new biological active hexapeptide of c-terminal of nocistatin, contains glu-gln-lys-gln-leu-gln sequence was synthesized according to solid phase peptide synthesis on the surface of 2-chloro tritylchloride resin and using fmoc-protected amino acids in the presence of tbtu (o-(benzotriazol-1-yl)-n,n,n',n'-tetramethyl uranium tetrafluoroborate) as a coupling reagent. then, amidation o...

BACKGROUND Objective methods to assess the adequacy of medication therapy for patients with advanced heart failure are lacking. Serial measurements of biomarkers might be beneficial. Therapy guided by N-terminal pro-B-type natriuretic peptide (NT-proBNP) might be helpful because NT-proBNP should be lowered by therapies that decrease endogenous BNP secretion. METHODS NT-proBNP and BNP were mea...

BACKGROUND Measurement of B-type natriuretic peptide (BNP) concentration or its precursor (N-terminal fragment [NT-proBNP]) is recommended in patients with symptoms of left ventricular dysfunction and in other settings, but the relevance of these peptides to cardiovascular disease (CVD) in general populations or in patients with stable vascular disease is uncertain. METHODS AND RESULTS Data w...

OBJECTIVES The aim of the study was to evaluate the occurence of death and major adverse cardiac events (MACE) in patients with normal (group A) and elevated (group B) plasma bilirubin levels. PATIENTS AND METHODS We evaluated 124 patients (83% males, mean age 50.1 +/- 7.7 yrs) in New York Heart Association class II and III with hypertension-related chronic heart failure. We assessed the occu...

INTRODUCTION Early identification of septic patients at high risk of dying remains a challenge. The prognostic role of brain natriuretic peptide (BNP) or N-terminal pro-B-type natriuretic peptide (NT-proBNP) in septic patients remains controversial. The purpose of this systematic review and meta-analysis was to investigate the value of elevated BNP or NT-proBNP in predicting mortality in septic...

Reducing readmissions after hospitalisation for acute heart failure is the new challenge of these diseases, approaching 30% within 60 to 90 days of discharge. Congestion related to high ventricular filling pressures, reflected by the high levels of natriuretic peptides, is the main reason for heart failure readmission. Natriuretic peptide levels are a patent prognostic marker of cardiovascular ...

BACKGROUND While the N-terminal pro-brain-type natriuretic peptide (NT-proBNP) at rest is known to be associated with prognosis in pulmonary arterial hypertension (PAH), it is unclear if the NT-proBNP response to exercise (ΔNT-proBNP) can contribute to a better assessment of disease severity. METHODS We investigated the association of NT-proBNP values at rest and during peak exercise with hem...
