目的 应用高频超声检测高血压前期人群双侧颈动脉内-中膜厚度(IMT)及斑块形成情况,探讨其颈动脉粥样硬化程度.方法 对590名高血压前期人群进行颈部血管超声检查,测算内-中膜厚度及斑块积分,并与1162名正常对照人群进行对比分析.结果 高血压前期人群颈动脉粥样硬化发生率增高,颈动脉内-中膜厚度(IMT)及斑块积分增加,与正常对照人群比较差异均具有统计学意义.高血压前期人群颈动脉粥样硬化斑块的检出率为45.3％,其中软斑占68.9％,混合斑占24.6％,硬斑占6.5％.结论 高频超声能准确检测高血压前期人群颈动脉IMT厚度及斑块形成情况,有利于早期辨别高血压前期高危人群.

Objective To investigate carotid intima-media thickness and arterioles atherosclerosis in patients with prehypertension by using high-frequency ultrasound.Methods A total of 1162 healthy controls and 590 prehypertensive patients were enrolled in this investigation.High-frequency ultrasound was used to measure intima-media thickness and evaluate plaque score of the carotid artery.Results In comparison with the healthy controls,the incidence of carotid atherosclerotic plaque and the intima-media thickness of the prehypertensive patients were significantly increased.The detection rate of carotid atherosclerotic plaque was 45.3％ in prehypertensive subjects.In addition,mild,moderate or calcified plaque was found in 68.9％,24.6％ and 6.5％ patients,respectively.Conclusion High frequency ultrasound could accurately evaluate intima-media thickness and atherosclerotic plaque of the carotid artery,which may be conductive to identify high-risk prehypertensive populations.
