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...
PURPOSE The aim of the study was to evaluate the utility of N-terminal pro-B-type natriuretic peptide (NT-pro BNP, pg/ml) assessment to predict infarct size and left ventricle function after ST-segment elevation myocardial infarction (STEMI) at long-term follow-up. METHODS In 45 patients with first STEMI less than 3 hours from symptom onset treated with mechanical reperfusion NT-pro BNP was a...
OBJECTIVES This study sought to characterize factors influencing amino-terminal pro-B-type natriuretic peptide (NT-proBNP) and to evaluate the ability of NT-proBNP to detect left ventricular (LV) dysfunction in a large community sample. BACKGROUND Secretion of BNP increases in cardiac disease, making BNP an attractive biomarker. Amino-terminal proBNP, a fragment of the BNP prohormone, is a ne...
BACKGROUND AND OBJECTIVES The plasma concentration of N-terminal pro-brain natriuretic peptide (NT-pro-BNP) is a st-rong prognostic indicator for patients with heart failure (HF) across all stages of the condition. Several clinical trials have de-monstrated convincingly that neurohormonal modulation on the renin angiotensin system (RAS) decreases plasma NT-pro-BNP level and results in favorable...
AIMS The Cardiac Resynchronization-Heart Failure (CARE-HF) study demonstrated that cardiac resynchronization therapy (CRT) could reduce morbidity and mortality and improve cardiac function in patients with moderate or severe heart failure secondary to left ventricular systolic dysfunction and markers of cardiac dyssynchrony. The purpose of this analysis was to investigate the effect of CRT on p...
BACKGROUND Altered thyroid function and increased rates of N-terminal pro-B-Type natriuretic peptide (NT-pro-BNP) are highly prevalent in coronary artery disease (CAD) patients with heart failure, and are associated with unfavorable prognosis. This study was undertaken to examine the relationship and prognostic impact of thyroid hormones, inflammatory biomarkers, and NT-pro-BNP on long-term out...
Acute myocardial infarction (MI) results in activation of neurohormonal systems and increased plasma concentrations of myocardial enzymes and structural proteins. We hypothesized that plasma levels of N-terminal pro-brain natriuretic peptide (NT-BNP) would respond more vigorously after MI than those of other natriuretic peptides. We also sought to compare this response with that of the establis...
B-type natriuretic peptide (BNP) is a member of a fournatriuretic peptide family that shares a common 17-peptide ring structure. The N-terminal fragment (NT-pro-BNP) is biologically inert, but both are secreted in the plasma in equimolar quantities and both have been evaluated for use in the management of congestive heart failure. BNP and NT-pro-BNP are frequently used in the diagnosis of conge...
AIM to evaluate whether pro BNP can be used for detection of diastolic dysfunction. METHODS thirty nine hypertensive patients with normal systolic function, consecutively referred for echocardiography examination between October and December 2004 were recruited in the study. Diastolic dysfunction was diagnosed when echocardiographic mitral flow pattern demonstrated impaired relaxation, pseudo...
Vascular diseases are the most prevalent diseases worldwide. This study intended to analyze peripheral blood miRNA levels and their correlation with NT-pro-BNP and cTN-I in patients with atherosclerosis or pre-atherosclerotic conditions to build a dynamic correlation between vascular diseases and their biomarkers. Serum NT-pro-BNP and cTN-I levels were measured by their respective ELISA kits. T...
