Abstract:
Objective To explore the changes and significance of plasma cardiotrophin-1 (CT-1) in children with heart failure.Methods Forty children with heart failure (NYHA Ⅱ,n =14;NYHA Ⅲ,n =16;NYHA Ⅳ,n =10)were chosen as observation group,and 20 healthy children without heart failure were taken as healthy control group.Plasma CT-1 was measured by a double antibody sandwich enzyme-linked immunosorbent assay (ELISA).N terminal probrain natriuretic peptide(NT-pro BNP) concentration was tested by Pu Rui fluorescent dry quantitative analyzer.Left ventricular ejection fraction(LVEF) was evaluated by GE Vivid 7 doppler echocardiography and cardiac function assessed by modified ROSS score.Plasma CT-1 level,NT-pro BNP and LVEF were compared between the 2 groups.The correlation of plasma CT-1 level with NT-pro BNP and LVEF were analyzed in patients with different degrees of heart failure.Results Plasma levels of CT-1 and NT-pro BNP were significantly higher in children with heart failure than those in healthy control group (P ＜ 0.01),and with progression of heart failure,the levels of CT-1 and NT-pro B NP progressively increased in heart failure children.Plasma CT-1 level in different NYHA had statistical significance (F =55.5,P ＜0.01).Plasma CT-1 level was positive correlated with NT-pro BNP and modified ROSS score(r =0.787,0.848,all P ＜ 0.01),and negative associated with LVEF (r =-0.66,P ＜ 0.01),respectively,in heart failure children.Conclusions Plasma CT-1 level is significantly elevated in heart failure children.There are good correlation among CT-1,NT-pro BNP and LVEF.Plasma CT-1 is a reliable marker of reflecting the severity of heart failure,combined with NT-pro BNP detection helps to improve the diagnostic accuracy of heart failure in children.
