The role of atrial natriuretic peptide and endothelin 1 on congenital heart failure of newborns / 中国综合临床

ABSTRACT

Objective To investigate the role of atrial natriuretic peptide(ANP) and endothelin 1 (ET-1) of newborns with congenital heart failure and its clinical significance.Methods One hundred newborns with congenital heart disease were selected as our subjects.They were divided into 3 groups according to cardiac function grading criteria and that were grade Ⅰ group(30 cases),grade Ⅱ group(40 cases) and grade Ⅲ-Ⅳ group(30 cases).Another 30 normal newborns were served as control group matched with age,gender.ET-1,ANP were detected.Results The levels of ET-1 and ANP in newborns of grade Ⅲ-Ⅳ were (132.35 ±5.26) ng/L and (9.25 ± 2.37) pmol/L,significant higher than that in control group((53.62 ± 3.81) ng/L and (1.15 ±0.09) pmol/L;P ＜0.01).As the severity of the disease in newborns with congenital heart failure,the level of ET-1,ANP were activated more.There was a positive correlation between ET-1 and grade of cardiac function (r =0.35,P ＜ 0.01).Meanwhile,it also showed a positive correlation between ANP and cardiac function (r =0.72,P ＜ 0.01).Conclusion ET-1,ANP in newborns with congenital heart disease are activated with characterized of chronic heart failure,and related to severity of the disease.
