Objective 　To explore the risk factors of carotid artery atherosclerotic plaque in ischemic stroke patients.
Methods 　One hundred and forty-eight patients with ischemic stoke were allocated into two groups by ultrasonographic testing (80 with plaque and 68 without plaque). The carotid artery acoustic densitometry (IMT), blood pressure, blood glucose , blood lipid, fibriongen (FIB), c-reactive protein (CRP) were tested. First, single variable analysis was conducted and then multivariate non-condition stepwise logistic model analysis was conducted.
Results 　Carotid IMT, age , total cholesterol (TC), low density lipoprotein (LDL)-CH, FIB, CRP level and the incidence of hypertension and diabetes were significantly higher in ischemic stroke patients with carotid artery plaques than patients without plaques (P≤0.05); Multiple logistic regression analysis showed the most important risk factors of plaques were CRP (OR=3.546, P=0.035) and FIB (OR=1.074, P=0.012) level.
Conclusion　 The main risk factors of carotid atherosclerosis plaque are almost the same as atherosclerosis, such as age , hypertension ,diabetes, hyperlipidemia , high FIB and CRP level and increase in carotid IMT. CRP and FIB may play a crucial role in the development of carotid artery atherosclerosis plaque.
