纤维蛋白原、C反应蛋白及同型半胱氨酸与大动脉粥样硬化型卒中患者颈动脉易损性斑块的相关性分析

摘要

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.%目的 探讨血清纤维蛋白原(FIB)、C反应蛋白(CRP)及同型半胱氨酸(Hcy)水平与大动脉粥样硬化(LAA)型卒中患者颈动脉易损性斑块的关系.方法 收集2014年3月-2015年2月兰州大学第二医院神经内科连续收治的急性缺血性卒中(AIS)住院患者,依据TOAST分型选择其中的LAA型前循环区域卒中患者273例,根据颈部血管超声结果分为无斑块组(n=84)、稳定斑块组(n=42)、易损斑块组(n=147),另收集同期住院的非脑卒中患者中无颈动脉病变的182例作为对照组,比较4组患者19项人口学和血液检测指标的差异.采用Logistic回归对LAA型卒中患者颈动脉易损性斑块的危险因素进行筛选,采用Spearman秩相关对患者颈动脉斑块易损性与各指标的相关性进行分析.结果FIB、CRP及Hcy水平在四组间的比较差异有统计学意义(P<0.05);多因素Logistic回归分析显示,FIB(OR=1.408,95%CI 1.028-1.927,P=0.033)是LAA型卒中患者颈动脉易损性斑块的独立危险因素;Spearman相关分析显示,FIB(r=0.292,P=0.000)、Hcy(r=0.172,P=0.000)与LAA型卒中患者颈动脉斑块易损性呈正相关.结论 血清FIB、Hcy水平可能是预测LAA型卒中患者颈动脉斑块易损性的生物学指标;血清CRP水平与LAA型卒中患者颈动脉斑块易损性无明显关联.
