Our previously study showed that serum Ang-(1-7) level was decreased in patients with PAH due to congenital heart disease(CHD). The present study aimed to investigate the changes of serum Ang-(1-7) before and after intervention closure. Methods fifty-nine patients with CHD were included. The patients were divided into non-PAH(group A), mild PAH(group B) and moderate PAH(group C). The serum Ang-(1-7) was detected by enzyme-linked immunosorbent assay(ELISA) at 1 day before operation and 2 days after operation. Results Before intervention closure, serum angiotensin-(1-7) level was significantly lower in group C than that in group A and group B. After intervention closure operation, serum Ang-(1-7) level was increased in group B and group C. Conclusion Serum Ang-(1-7) level is increased in PAH patients after interventional closure operation of CHD, which might be used as potential clinical biomarkers to evaluate the postoperative prognosis for these patients.[S Chin J Cardiol 2019;20(4):264-268]展开更多
