Background: Cardiac dysfunction is one of the major causes of morbidity and mortality in thalassemia patients. This study aimed to compare the effect of Brain Natriuretic Peptides (BNP) and Calcitonin Gene-Related Peptide (CGRP) with echocardiographic findings in early diagnosis of cardiac disease in major thalassemia patients. Materials and Methods: This study was performed on 80 patients amo...

OBJECTIVES To determine the diagnostic accuracy of the measurement of plasma B-type natriuretic peptide (BNP) and N-terminal pro-BNP (NTproBNP) in patients referred by their general practitioners (GPs) with symptoms suggestive of heart failure. Additionally, to compare the diagnostic accuracy of the resting 12-lead electrocardiogram (ECG) with that of the peptides. DESIGN A diagnostic accurac...

BACKGROUND The concentrations of atrial and brain natriuretic peptides (ANP and BNP) are elevated in patients with atrial fibrillation (AF), but the usefulness of their measurement before and after AF ablation has not been reported. METHODS AND RESULTS The concentrations of the natriuretic peptides were evaluated in 54 patients undergoing catheter ablation for drug-resistant paroxysmal and pe...

background: brain type natriuretic peptide (bnp) is a cardiac hormone that is secreted mainly by the ventricles in response to volume expansion and pressure load. it can predict post-operative complications after heart surgery in adults. we sought to investigate the prognostic value of bnp in children after heart surgery. methods: we measured the bnp serum levels in 96 children with congenital ...

The levels and pathophysiological role of amino terminal C-type natriuretic peptide in heart failure are unknown. The potential of plasma amino-terminal C-type natriuretic peptide (N-CNP) as a marker of cardiac function was investigated in symptomatic patients. In 305 patients with recent-onset dyspnea and/or peripheral edema, presenting to primary care, assay of plasma amino-terminal C-type na...

BACKGROUND Newly discovered circulating peptides, N-terminal pro-brain natriuretic peptide (N-BNP) and adrenomedullin (ADM), were examined for prediction of cardiac function and prognosis and compared with previously reported markers in 121 patients with myocardial infarction. METHODS AND RESULTS The association between radionuclide left ventricular ejection fraction (LVEF) and N-BNP at 2 to ...

Brain natriuretic peptide (BNP) is secreted by cardiomyocytes in response to excessive stretching. BNP plasma levels are useful for diagnosis in patients with dyspnea [1] predicting heart failure better than clinical assessment alone [2]. Therefore, determination of BNP when heart failure is suspected has become standard of care [3]. However, for patients with established heart failure who unde...

Gene expression and secretion of the cardiac polypeptide hormones atrial natriuretic factor (ANF) and brain natriuretic peptide (BNP) are simultaneously upregulated in various cardiac disorders such as congestive heart failure, ischemic heart disease, and hypertensive heart disease, in which hemodynamic or neuroendocrine changes are key components in the progression of disease. However, during ...

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...

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...
