摘要
目的:探析B超技术对老年高血压(HBP)患者颈动脉结构及血流动力学变化的诊断意义。方法:选择本院2021年4月~2022年7月门诊就诊的120例老年HBP患者作为观察组,选择同期接受B超诊断的120例健康老年人作为对照组。两组均采用B超诊断,对比两组颈动脉结构相关参数[颈总及内动脉结构的内径、中膜厚度(IMT)]、斑块分布情况及发生率、血流动力学相关参数[包括颈总及内动脉结构的收缩期峰值血流速度(PSV)、血管阻力指数(RI)、血流最大剪切率(SR)]。结果:观察组老年HBP患者颈总动脉结构的内径(t=7.949)、IMT(t=13.715)、颈内动脉结构的内径(t=5.781)、IMT水平(t=14.111)均高于对照组(P均<0.05);观察组老年HBP患者斑块检出率(47.50%)明显高于对照组(5.00%),χ^(2)=55.980,P<0.05;观察组老年HBP患者颈总动脉结构的PSV(t=10.360)、SR(t=10.3603)、颈内动脉结构的PSV(t=16.465)、SR(t=7.653)均低于对照组,而颈总动脉结构RI(t=15.011)、颈内动脉结构RI(t=17.963)均高于对照组(P均<0.05)。结论:B超技术应用于老年HBP疾病中诊断效果显著,可通过特异性显示颈动脉结构及血流动力学变化特征,及时预测心血管事件发生风险。
Objective:To explore the diagnostic significance of B-ultrasound in carotid artery structure and hemodynamic changes in elderly patients with hypertension(HBP).Methods:A total of 120 elderly patients with HBP who visited the outpatient department of our hospital from April 2021 to July 2022 were selected as the observation group,and 120 healthy elderly patients who received B-ultrasound diagnosis during the same period were selected as the control group.Both groups were diagnosed by B-ultrasound.The parameters related to carotid artery structure(internal diameter of common carotid artery and internal carotid artery structure,media thickness(IMT)),plaque distribution and incidence,hemodynamic parameters(including peak systolic blood flow velocity(PSV),vascular resistance index(RI),maximum shear rate(SR))of common carotid artery and internal carotid artery structure were compared between the two groups.Results:The internal diameter of common carotid artery(t=7.949),IMT(t=13.715),internal diameter of internal carotid artery(t=5.781)and IMT level(t=14.111)in the observation group were higher than those in the control group(all P<0.05).The detection rate of plaque in elderly patients with HBP in observation group(47.50%)was significantly higher than that in control group(5.00%),χ^(2)=55.980,P<0.05.The PSV(t=10.360),SR(t=10.3603),PSV(t=16.465),SR(t=7.653)of the common carotid artery structure in the observation group were lower than those in the control group.The structural RI of common carotid artery(t=15.011)and internal carotid artery(t=17.963)were higher than those of the control group(all P<0.05).Conclusion:The application of B-ultrasound in the diagnosis of HBP disease in the elderly has a significant effect.It can predict the risk of cardiovascular events in time by specifically displaying the structure and hemodynamic changes of carotid artery.
