Changes of prethrombotic state molecular markers after percutaneous coronary intervention in patients with coronary artery disease with hypertension

摘要

Background The changes of pre-thrombotic state molecular markers(PSMMs) were investigated in patients with coronary artery disease(CAD) complicated by hypertension(HBP) after percutaneous coronary in-tervention(PCI), and their significances were evaluated. Methods Totally 70 patients with CAD were divided two groups: group A including 32 patients with CAD, and group B 38 patients with CAD complicated by HBP.All the patients received PCI. The levels of PSMMs were measured before PCI and 20 minutes, 24 hours, and7 days after PCI respectively. The patients were followed up for cardiac events after PCI for 6 months. Results(1) Compared with the data before PCI, the changes in von Willrand Factor(vWF), coagulation fators Ⅷ antigen(Ⅷ:Ag), antithrombin Ⅲ(ATⅢ), granular membrane protein-140( GMP-140), factor Ⅱ activity( F.Ⅱa),fibrinogen(Fbg), plasminogen(Plg), tissue plasminogen activator(t-PA), plasminogenemia activator inhibitor(PAI), and D-dimer were significant at 20 minutes after PCI(P < 0.05 or P < 0.01), and the changes in vWF,protein C(PC), Fbg, Plg, PAI, D-dimer were significant at 24 hours after PCI in group A(P < 0.05 or P <0.01).(2) Compared with the data before PCI, the changes in vWF, Ⅷ:Ag, ATⅢ, GMP1-40, PC, F.Ⅱa, Fbg,PAI, and D-dimer at 20 minutes, 24 hours, and 7 days after PCI were significant in group B(P < 0.05 or P <0.01). Conclusions There are significant changes of PSMMs in patients with CAD after PCI, especially in those with CAD complicated by HBP.
