短暂性脑缺血患者颈动脉粥样硬化及相关危险因素分析

目的探讨短暂性脑缺血发作(TIA)患者颈动脉粥样硬化(AS)斑块发生与年龄、高血压等危险因素的关系.方法对109例TIA患者的颈动脉超声检查结果及动脉粥样硬化的危险因素采用Logistic回归分析法进行分析.结果TIA患者颈动脉斑块的发生率为60.55%,斑块的发生与年龄、高血压史、胆固醇水平、ApoE-B水平相关.青年TIA患者已有早期动脉硬化-内膜-中膜厚度(IMT)的改变.动脉粥样硬化斑块以颈动脉球部多发,以等回声、不均回声斑块为主.结论TIA患者的颈动脉AS发生率极高,斑块的发生与年龄、高血压、血脂呈正相关.

Analysis on correlation of carotid artherosclerosis and its risk facters in patients with transient ischemic attack

Objective This study was aimed to assess the relationship between carotid plaque and cerebral vascular risk factors in patients with transient ischemic attack (TIA). Methods Color Doppler flow imaging (CDFI)was used to investigate carotid artherosclerosis in 109 patients with TIA, and various risk factors of artherosclerosis were evaluated. Results Carotid plaque were observed in sixty-six cases(60.55%),Logistic analysis identified that age ,hypertension, and level of cholesterol and ApoE-B were accouted for carotid artherosclerosis.Even young patients showed early changes of intima-medium thickness (IMT). Plaques were mostly located near the bifurcationof the common carotid artery, and there was high percentage of even and unequal echo inside the Carotid plaques. Conclusions The carotid artherosclerosis is very common in TIA,and is positively related with age, hypertension, and lipid level.
