Several studies have indicated association between hematologic markers and increased risks of cerebrovascular disease, but few reports referred to their roles together. We studied plasma levels of 16 hematologic markers in 50 cases diagnosed as acute cerebral infarction (ACI) and 54 hospital control subjects. Plasma levels of thrombomodulin, fibrinogen, and activity of tissue factor (aTF) were significantly higher in cases than in control subjects (P < .001, P < .01, and P < .05, respectively). Multivariate logistic regression analysis showed that hypertension and high plasma levels of thrombomodulin, fibrinogen, and aTF were significantly associated with presence of ACI (odds ratio [OR], 143.74, P < .001; OR, 2.05, P < .05; OR, 2.09, P < .05; OR, 1.02, P < .05, respectively). Our findings indicate that hypertension and elevation of plasma thrombomodulin, fibrinogen, and aTF are independent risk factors for ACI.
