ABSTRACT
Objective To investigate the effect of clopidogrel on platelet function and inflammation factor in treatment of severe carotid artery stenosis after stent-assisted angioplasty.Methods Patients (120 cases) with severe carotid artery stenosis after stent-assisted angioplasty were chosen and divided into two groups,the control group were given atorvastatin combined with aspirin,and the observation group were given atorvastatin combined with chlorine.The serum coagulants DD level,FIB level,inflammation factor P-chosen element level and restenosis event incidence of two groups were observed.Results D-double polymer of two groups had no significant difference;After surgery,the D-double polymer and FIB level of two groups were all higher (P ＜ 0.05).After surgery for 24 h,the D-double polymer and FIB level of observation group were higher,after 3 months of surgery,the D-double polymer and FIB level had no significant differences compared with before surgery,which were all in normal level.After 24 h,1 month,3 months of surgery,the D-double polymer and FIB level of observation group were all lower than control group (P ＜ 0.05).Before treatment,the P-chosen selectin of two groups had no significant differences,which were all decreased after surgery,and the observation group was lower than control group (P ＜ 0.05);The restenosis event of observation group was lower than control group (P ＜ 0.05).Conclusion Clopidogrel could control the platelet aggregation of severe carotid stenosis after surgery to prevent the thrombogenesis and decrease the restriction incidence,while control the inflammation factor expression to prevent the atherosclerosis.
