background: n-terminal pro-brain natriuretic peptide (nt-probnp) is a sensitive biomarker for the detection of asymptomatic left ventricular (lv) dysfunction. since β-thalassemia major patients suffer from early diastolic dysfunction due to iron deposition of chronic blood transfusion, we tried to evaluate the correlation between the serum nt-probnp level and the severity of lv diastolic dysfun...

Objectives: To determine whether blood natriuretic peptide concentrations are helpful in identifying or excluding left ventricular systolic dysfunction in stable survivors of acute myocardial infarction. Design: Comparison of blood natriuretic peptide concentrations with echocardiographic assessment of left ventricular systolic function in a general practice population. Setting: Practices in We...

OBJECTIVE To assess prognosis of pulmonary thromboembolism using tissue Doppler echocardiography and brain natriuretic peptide. METHODS Patients aged over 18 years were evaluated within 24 hours of confirmed diagnosis (chest tomography/pulmonary scintigraphy) of pulmonary embolism using two-dimensional echocardiography and tissue Doppler for right ventricular systolic (s') velocities, strain,...

conclusions the results of the current study suggested that spinal anesthesia plus intravenous patient-controlled analgesia have the most favorable cardiac effects regarding postoperative levels of pro-bnp. results there was no difference between three groups for basic characteristics and variables and baseline pro-bnp levels; however, postoperative pro-bnp levels in groups a, b, and c were res...

Background: Dilated cardiomyopathy (DCM) is revealed with the left ventricular dilatation and systolic dysfunction. This study was performed to determine the level of Calcitonin Gene Related Peptide (CGRP) and Brain Natriuretic Peptide (BNP) in children with dilated cardiomyopathy and controls and comparison of these two biomarkers in patients. Materials and Methods: This case-control study was...

The present review will cover the mechanisms of release and the potential pathophysiological role of different natriuretic peptides in critically ill patients. By focusing on the cardiovascular system, possible implications of natriuretic peptides for diagnosis and treatment will be presented. In critical illness such as sepsis, trauma or major surgery, systemic hypotension and an intrinsic myo...

The prevalence of heart failure is increasing. Patients usually present to their general practitioner but a definitive diagnosis of left ventricular systolic dysfunction can only be achieved by cardiac imaging. Measuring plasma concentrations of brain natriuretic peptide has been advocated as a screening test that might reduce demands on cardiological services. We report the results of a commun...

sarily induce a large increase in left ventricular wall stress because of the obliterated left ventricular cavity in midto late systole as a result of hyperdynamic ejection. This reasoning was supported by micromanometer left ventricular and aortic pressure and flow measurements, but challenged by the outcome of myectomy surgery which resulted in significant improvement in symptoms and in radio...

AIMS Atrial and brain natriuretic peptide levels closely reflect impaired left ventricular function in patients with heart failure. In the present study we assessed the determinants and the clinical significance of atrial and brain natriuretic peptide plasma levels in hypertrophic cardiomyopathy. METHODS AND RESULTS In 44 patients with hypertrophic cardiomyopathy (40+/-15 years) we evaluated:...
