Abstract:Objective : To investigate the changes of plasma fibrinogen level among acute ischemic stroke(ACI) subtypes according to Trial of Org10172 in Acute Stroke Treatment (TOAST) criteria and effects of Songling Xuemaikang. Method : The 160 patients with acute iachemic stroke were divided into two groups randomly: treatment group 85 cases (Songling Xuemaikang + Shuxuetong+ Aspirin enterie ccoated tablets), control group 75 cases (Shuxuetong + Aspirin enterie ccoated tablets).The plasma fibrinogen was detected before and after treatment. Result : Compared with OC subtype, Fbg was higher in LAA, CE and SAO subtypes (P<0.05). Compared with UE subtype, Fbg was higher in LAA, CE and SAO subtypes (P<0. 05). There was a significantly difference between LAA and SAO (P<0.05). In LAA,SAO,CE of treatment group,the Fbg level were lowered significantly at the 15th day compared with pretherapy (P<0.05). There was a significantly difference of Fbg between treatment group and control group In LAA, SAO and CE subtypes at the 15th day (P<0.05). Conclusion : Fbg produces a marked effect at the pathomechanism of LAA, SAO and CE subtypes. Songling Xuemaikang can depress the plasma fibrinogen level of ACI, and be an effective adjunctive therapy on ACI.
