Abstract:
Objective To explore the correlation between the serum levels of fibrinogen (FIB), C-reactive protein (CRP) and homocysteine (Hcy) with the carotid vulnerable plaque in patients with large artery atherosclerosis (LAA) stroke.Methods The patients with acute ischemic stroke (AIS) admitted to the Department of Neurology in The Second Hospital of Lanzhou University from Mar. 2014 to Feb. 2015 were collected continuously, and 273 patients with anterior circulation of LAA stroke were selected based on the TOAST classification. These patients were classified as non-plaque group (n=84), stable plaque group (n=42) and vulnerable plaque group (n=147) according to the carotid ultrasonography examination. Another 182 patients without carotid disease of non-stroke selected simultaneously from our department were regarded as controls. The 19 demographic parameters and hematological indices were compared among the four groups. The logistic regression was used to screen the independent risk factors for carotid vulnerable plaque in LAA stroke patients. The Spearman rank correlation was performed to analyze the correlation between the carotid plaque vulnerability in LAA stroke patients with all the indicators.Results The levels of FIB, CRP and Hcy in the four groups showed statistically signicantcant differences (P<0.05). The multivariate logistic regression analysis revealed that FIB (OR=1.408, 95% CI 1.028-1.927,P=0.033) was the independent risk factor for carotid vulnerable plaque in patients with LAA stroke. The Spearman correlation analysis presented a positive correlation between carotid plaque vulnerability in LAA stroke patients with FIB (r=0.292;P=0.000) and Hcy (r=0.172;P=0.000). Conclusions The serum FIB and Hcy levels may be the meaningful biomarkers to predict the vulnerable carotid plaque in patients with LAA stroke. The serum level of CRP has no obvious correlation with carotid plaque vulnerability in LAA stroke patients.
