摘要(Abstract):

目的:探讨原发性高血压患者颈动脉粥样硬化的发病特点及超声检查的临床价值。方法:对332例原发性高血压患者按照血压水平分为高血压1级组、2级组和3级组,并选择32例血压正常对照者进行颈动脉彩色多普勒超声检查,测量颈动脉内膜-中层厚度(IMT)和颈动脉内径,并观察斑块发生及颈动脉狭窄情况。结果:高血压各组颈动脉IMT均较对照组增厚,差异有显著性(P<0.01);高血压各组颈动脉内径均大于对照组(P<0.01),高血压各组之间颈动脉内径比较差异有显著性(P<0.05);高血压各组斑块检出率较对照组增高,差异有显著性(P<0.01);颈动脉粥样斑块多发生于颈动脉分支处。结论:彩色多普勒超声可以了解高血压患者颈动脉粥样硬化的病变情况,可作为早期发现和筛选心脑血管疾病的重要手段。
Objective: To investigate morbility characteristics of carotid atherosclerosis in essential hypertension patients,and to assess the value of ultrasound examination in this disease.Methods: Three hundreds and thirty-two essential hypertension patients were divided into three groups according to their blood pressure levels: group 1(70 cases),group 2(131 cases) and group 3(131 cases).Carotid color doppler ultrasonography was performed on the patients and 32 people with normal blood pressure.Inner membrane and media thickness(IMT) of carotid and inner diameter of it were detected.Plaque development and carotid artery stenosis status were observed.Results:Carotid artery IMT of essential hypertension patients was thicker than that of control cases,and the difference was significant(P<0.01).Inner diameters of carotid artery of hypertension patients were bigger than those of control cases,and the difference was significant(P<0.05).The detection rates of plaques in carotid artery of hypertension patients were much higher than those of control cases(P<0.01).The plaques usually occurred on the fork part of carotid artery.Conclusions: Color Doppler ultrasound helps to understand the degree of carotid atherosclerosis of essential hypertension patients,and it is an important method for early discovery and screening of high-risk patients with cardio-cerebrovascular disease.
