Abstract:
Objective To detect neuroendocrinal factor,and explore whether neurohormonal activation exists in children with conge-nital heart disease(CHD).Methods Concentrations of atrial natriuretic peptide(ANP),brain natriuretic peptide(BNP),angiotensionⅡ(AngⅡ),aldosterone(ALD),endothelin-1(ET-1),and norepinephrine(NE)were determined in 100 children with CHD and were assayed at 24 hours,1 month,3 months and 6 months after interventional therapy in 70 cases with CHD.Results Children with CHD heart disease had elevated levels of ANP(25.6?7.5) pmol/L,BNP(15.7?7.4) pmol/L,ET-1(1.12?0.31) pmol/L(all P=0.0001),(AngⅡ)(90.3?11.5) ng/L,NE(1.07?0.08) nmol/L and ALD(246.1?42.3) pmol/L(all P=0.001).There was a highly significant stepwise increase in ANP,BNP,ET-1,AngⅡ,ALD and NE according to New York Heart Association class,with even asymptomatic patients having evidence of significant neurohormonal activation.The neurohormonal function gradually returned to normal after interven-(tional) therapy.Conclusions Neurohormonal activation in children CHD bears the hallmarks of chronic heart failure,relating to symptom severity and ventricular dysfunction.
