Evaluation of Brain Natriuretic Peptide in Children with Dilated Cardiomyopathy / 实用儿科临床杂志

ABSTRACT

Objective To determine the correlation of plasma brain natriuretic peptide(BNP) with severe degree of dilated cardiomyopathy in children.Methods Thirty children with dilated cardiomyopathy and 30 healthy subjects were selected in this degree of study, plasma BNP concentration was measured and compared among groups by using t test.Correlation of BNP levels with left ventricular ejection fraction and heart function was investigated using linear regression analysis.Results Children with dilated cardiomyopathy had significantly higher mean BNP levels compared with healthy children [(429.4?270.2) ng/L vs (67.0?10.2) ng/L].Significantly positive correlations were found between BNP and heart classification(r=0.950 P
