Brain-derived natriuretic peptide (BNP) is a cardioprotective peptide released, together with the inactive NH(2)-terminal part of its prohormone (NT-pro-BNP), in response to different kinds of myocardial stress. Hypoglycemia and hypoxemia are conditions that threaten cellular function and hence potentially stimulate BNP release. BNP interacts with the renin-angiotensin system (RAS). The aim of ...
مقدمه: امروزه یکی مهم ترین مشکلات بیماران تالاسمی ماژور، اضافه بار آهن و هموسیدروز می باشد، که پیامد آن رسوب آهن در بافت میوکارد و وقوع کاردیومیوپاتی ناشی از هرماکروماتیز است. هدف از انجام پژوهش حاضر، تعیین تأثیر هشت هفته تمرین مقاومتی - استقامتی هم زمان بر مقادیر سرمی nt-pro bnp و فریتین، بیماران بتا تالاسمی ماژور بود. روش کار: بدین منظور 18 نفر از بیماران بتاتالاسمی ماژور مرکز بیماری های خاص ...
background heart failure is a major cause of death in thalassemia. the study aimed to determine the diagnostic value of n terminal pro b type natriuretic peptide (nt-pro bnp), to early diagnose the cardiac involvement in beta- thalassemia major patients. materials and methods 80 thalassemia patients aged 7 to 18 years old (patients group), and 80 healthy age and gender matched controls were en...
BACKGROUND Brain-type natriuretic peptide (BNP) and the amino-terminal fragment of its prohormone (NT-proBNP) are known predictors of cardiovascular outcomes in patients with coronary heart disease; however, the relative prognostic value of these 2 biomarkers for secondary events remains unclear. METHODS AND RESULTS In 983 participants with stable coronary heart disease, we evaluated the asso...
BACKGROUND Most patients with surgically corrected tetralogy of Fallot (TOF) are faced with multiple residua and sequelae such as pulmonary regurgitation (PR), resulting in reoperation for pulmonary valve replacement (PVR). Plasma brain natriuretic peptide (BNP) level and serum N-terminal pro-BNP (NT-pro-BNP) level are useful as diagnostic objective markers of chronic heart failure (CHF). The ...
Correlation Between Levels of N-terminal Pro-B-Type Natriuretic Peptide and Degrees of Heart Failure
BACKGROUND The N-terminal fragment of pro Brain Natriuretic Peptide (NT-pro BNP) is a neuro-hormone synthesized in the cardiac ventricles in response to increased wall tension. The purpose of this study was to assess the correlation between the NT-pro BNP levels and the New York Heart Association function class (NYHA Fc) of dyspnea and echocardiographic findings for the patients who visited our...
BACKGROUND This study was undertaken to identify factors correlating with plasma levels of B-type natriuretic peptide (BNP) and its N-terminal portion (NTpro BNP) in the acute phase of Kawasaki disease (KD). METHODS This study included 91 patients with KD treated at a hospital affiliated to Hamamatsu University School of Medicine between October 2003 and June 2011. We quantified BNP and NT-pr...
BACKGROUND Plasma B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) are promising markers for heart failure diagnosis, prognosis, and treatment. Insufficient data on the intraindividual biological variation (CV(i)) of BNP and NT-proBNP hamper interpretation of changes in concentration on disease progression or treatment optimization. We therefore investigated CV(i) values in st...
BACKGROUND The data are inconsistent regarding whether extreme N-terminal fragment pro-B-type natriuretic peptide (NT pro-BNP) levels are associated with impaired renal function. Furthermore, the relationship between extreme NT pro-BNP levels and cardiac and renal function in elderly patients has not been reported. The aim of the present study was to examine a hypothesis that extreme NT pro-BNP...
B-type natriuretic peptide (BNP) is a 32 amino acid cardiacsynthesized hormone that reduces blood pressure and increases sodium excretion (1 ). Following proteolytic cleavage of proBNP, a 108-amino acid precursor, an Nterminal fragment (NT-proBNP) and BNP are released (2 ). Increased concentrations of BNP and NT-proBNP can be used clinically to monitor heart failure, but a lack of alignment bet...
