ABSTRACT
OBJECTIVE:
To establish the possible relationship between some coagulation factors and the onset of acute cerebral infarction (ACI).METHODS:
The study population consisted of 71 patients with ACI confirmed by CT and 50 age-matched healthy volunteers. Blood samples were obtained during the onset period of ACI. Tissue factor (TF) and tissue factor pathway inhibitor (TFPI) activity in plasma were assayed with the chromogenic assay. Plasma TF and TFPI antigen were measured with enzyme linked immunoadsorbent assay (ELISA). Plasma F VII coagulation activity (F VII C) and F VIII coagulation activity (F VIII C) were developed in the one-stage system. Plasma prothrombin (FII) was determined with Ecarin assay. Plasma fibrinogen (Fbg) was measured with thrombin assay. Plasma antithrombin III activity (ATIII) was determined using heparin cofactor activity assay.RESULTS:
Compared with the control, plasma TF activity and antigen in patients with ACI were significantly higher (both P<0.05). But plasma TFPI activity and antigen were remarkably lower in the ACI group (both P<0.05). Plasma F VII C was significantly higher (P<0.01), and F VIII C was markedly lower (P<0.05). Plasma FII was remarkably higher (P<0.01). Similarly the Fbg was significantly higher in the ACI than that in the control group (P<0.01), whereas ATIII was significantly lower (P<0.01).CONCLUSION:
The initiation of TF pathway is contributed to the onset of ACI and the blood is in hypercoagulable state during the early period of ACI.
