高血压患者颈动脉超声检测与分析

目的探讨各级高血压患者的颈动脉粥样硬化程度。方法检测分析380例高血压患者颈动脉内膜-中层厚度（CAIMT）、颈动脉内径（CADIA）、斑块发生率并与150例健康人对照。采用t检验和χ2检验对数据进行统计学分析,P〈0.05为差异有统计学意义。结果高血压组较对照组CAIMT及CADIA逐渐增加;随着高血压分级增加,CAIMT及CADIA逐渐增加（P〈0.05）;高血压组的斑块发生率明显高于正常对照组（P〈0.05）。结论 CAIMT增加、CADIA增加及斑块形成是颈动脉粥样硬化的特征,血压增高是引起高血压颈动脉变化的一个重要因素。

Ultrasound detection of carotid in hypertensive patients

Objective To explore the severity of carotid atherosclerosis in patients with different grades of hypertension.Methods Three hundred and eighty patients and 150 healthy persons were selected and divided into hypertension group and control group,respectively.The carotid-artery intima-media thickness（CAIMT）,carotid artery diameter（CADIA）,and the incidence rate of atherosclerosis plaques in the subjects were detected with color Doppler ultrasound.The data were analyzed with chi-square test and t test.P0.05 was considered as significant.Results The CAIMT and CADIA significantly increased in hypertension group than those in control group.It was also found that the CAIMT and CADIA increased with the increasing grade of hypertension（P0.05）.More patients developed atherosclerosis plaques in hypertension group than those in control group（P0.05）.Conclusion The carotid atherosclerosis is characterized by the increase of CAIMT and CADIA and the formation of plaque.Hypertension contributes to the development of carotid atherosclerosis.
