We measured plasma concentrations of vWF: Ag in 89 patients with congenital heart defects (left to right shunting) by quantitative immunoelectrophoresis and assessed endothelial vWF: Ag directly by an immunoperoxidase stain applied io lung biopsy tissue in 10 patients. The patients with pulmonary hypertension had significanthigher vWF: Ag levels, the elevation was associated with the elevation of PVR (P<0.01). The vWF: Ag levels varied directly with PVR and PAR (r=0.89, 0.82, P<0.05).The regression equations of vWF: Ag-PVR. vWF: Ag-PAR we made cam help us to estimate PVR noninvasiverly. Our study will provide us a theoretical basis to choose an appropriate occasion for corrective suryery.展开更多

Methods The Streptavidin-peroxidase (SP) immunoassay was used to measure the expression of ET-1 in pulmonary arteriola, pulmonary veinlet, endocardium and endangium of vasa coronary of 20 cases VSD of CHD with PH, and contrast the expression level of these 20 cases VSD of CHD with PH. Results The expression of ET-1 PH patients in pulmonary arteriola, endocardium, and endangium of vasa coronary was much higher than that of the control group (P<0.05), but there was no significance variance in expression level of pulmonary veinlet between two groups (P>0.05). Conclusion If VSD of CHD was accompany with PH, the degree of PH has a positive correlation with the amount of ET-1 in pulmonary arteriola, ET-1 may be the cause of dynamic PH, and also the acceleration factor of the PH. However, the amount of ET-1 in endocardium and endangium of vasa coronary, may have significant connection with the myocardium hypertrophy in dynamic PH.展开更多
