Abstract:
Objective Through detecting the levels of von willebrand factor (vWF) ,vWF-cleaving protease (vWF-cp)before and after percataneous coronary intervention (PCI) in patients with coronary atherosclerotic heart disease ,to evaluate the relationship between them .Methods According to the results of coronary angiography ,study objects were divided into control group (normal) and PCI group ( the diagnosis of coronary heart disease with PCI operation ) .Enzyme-linked immunosorbent assay (ELISA) was carrout to determin the levels of plasma vWF concentration and vWF-cp activity in plasma and statistical analysis .Results The pre-operative ,postoperative vWF levels in plasma in PCI group were significantly higher than that in the normal control group ;The plasma vWF levels after PCI were significantly higher than that in the group before PCI (P< 0 .05) ;vWF-cp level of the PCI group were lower than in the control group ,and postoperation is lower than preoperation ( P < 0 .05) .With the coronary artery lesion worsen ,the plasma level of vWF increased ,while the level of vWF-cp activity decreased .Conclusion vWF and vWF-cp levels with the severity of coronary atherosclerosis and thrombosis risk was increased in different decreased ,which may play an important role in the pathogenesis of acute coronary syndromes .Changes of vWF and vWF-cp level after PCI indicate that interventional therapy can increase the risk of thrombosis to some extent .
