摘要
Objective To investigate the correlation between plasma fibrinogen level and cerebral infarction (CI) as well as the difference of fibrinogen among subtypes of CI. Methods A case-controlled study was conducted with 131 cases of CI and 148 controls. Plasma fibrinogen levels were detected by the Clauss method. Results High fibrinogen level (3.09±0.94 g/L) was correlated with CI (OR=2.47, 95%CI: 1.51-4.04, P<0.005) at the onset stage of the disease. Persistent high fibrinogen level (3.14±0.81 g/L) at 6-month after stroke onset was detected and correlated with CI(OR=4.34,95% CI:1.80-10.51, P=0.001). Higher fibrinogen level was correlated with total anterior circulation infarction (TACI), partial anterior circulation infarction (PACI), and posterior circulation infarction (POCI) (OR=4.008, P<0.001). Higher fibrinogen level was correlated with extracranial atherosclerosis (OR=3.220, P<0.05), but not with intracranial atherosclerosis.Conclusion Fibrinogen level may be a risk factor of CI and probably correlates with subtypes of CI and distributions of atherosclerosis.
