    摘要:

    目的:探讨介入封堵房间隔缺损(ASD)前后患者血浆内皮素1(ET-1)浓度的变化及其临床意义-方法:检测40例成功接受介入封堵治疗的ASD患者的术前-术后30 min和术后3天血浆ET-1浓度-结果:无论ASD患者的肺动脉压是否升高,其血浆ET-1的浓度均明显高于正常对照组;术前ASD患者血浆ET-1浓度与PASP-Qp/Qs和ASD最大伸展径呈正相关,r分别为0.868-0.746-0.670(P均 < 0.01);ASD患者术后30 min和术后3天的血浆ET-1浓度较术前明显下降,术后3天的血浆ET-1浓度较术后30 min进一步下降-结论:介入封堵ASD后,患者的肺血管内皮功能得到改善,血浆ET-1浓度的检测可以作为评价介入封堵ASD疗效的指标-

    Abstract:

    Objective:To study the alteration and clinical significance of plasma endothelin-1(ET-1) after transcatheter closure of atrial septal defect(ASD). Methods:Radioimmumoassay was used to measure plasma concentration of ET-1 in 40 ASD patients before,30 minutes after and three days after transcatheter closure of ASD. Results:The plasma level of ET-1 in ASD patients was remarkably higher than that of the control,no matter the ASD patients’ pulmonary arterial pressure was increased or not. In ASD patients,the plasma concentration of ET-1 correlated with the pulmonary arterial pressure,pulmonary to systemic flow ratio(Qp/Qs) and the size of ASD(r = 0.868, r = 0.746 and r = 0.670,respectively(P < 0.01). The plasma level of ET-1 in ASD patients after ASD closure decreased significantly compared with the level before ASD closure. And the plasma concentration of ET-1 in ASD patients three days after ASD closure was lower than that at 30 minutes after ASD closure. Conclusion:The endothelium function in patients with ASD can be improved after transcatheter closure of ASD. The plasma level of ET-1 may be used as a marker for evaluating the effect of transcatheter closure of ASD.
