彩超评价高血压患者颈动脉粥样硬化与血流动力学变化的价值

Value of Color Doppler Ultrasound in Evaluating Carotid Atherosclerosis and Hemodynamic Changes in Patients with Hypertension

目的:对于高血压患者,分析彩超对其颈动脉粥样硬化、血流动力学的临床价值。结果:选取某院自2020年5月~2020年11月收治的30例高血压患者作为研究组,选取同期非高血压患者30例作为对照组,均行颈动脉彩超检查,比较组间颈总动脉内膜-中层厚度(IMT)、内径、斑块情况以及血流动力学水平。结果:研究组颈总动脉IMT水平显著高于对照组,内径大于对照组(P<0.05);研究组颈总动脉斑块阳性率高于对照组(P<0.05),且斑块性质组间存在明显区别(χ^(2)=57.700,P<0.01);研究组颈总动脉RI水平高于对照组,而PSV、EDV水平低于对照组(P<0.05)。结论:彩超可充分评估高血压患者颈动脉斑块、血流动力学情况,为临床早期筛查、早期干预具有指导意义。

Objective:To analyze the clinical value of color Doppler ultrasound on carotid atherosclerosis and hemodynamics in patients with hypertension.Methods:30 cases of hypertensive patients in a hospital from May 2020 to November 2020 were selected as the study group,and 30 cases of non hypertensive patients in the same period were selected as the control group.All patients underwent carotid artery color Doppler ultrasound examination,and the intima-media thickness(IMT),inner diameter,plaque condition and hemodynamic level of common carotid artery were compared between the two groups.Results:The IMT level of common carotid artery in the study group was significantly higher than that in the control group,and the inner diameter was larger than that in the control group(P<0.05).The positive rate of common carotid artery plaque in the study group was higher than that in the control group(P<0.05),and there was significant difference in plaque nature between the two groups(χ^(2)=57.700,P<0.01).The RI level of common carotid artery in the study group was higher than that in the control group,while the PSV and EDV levels were lower than those in the control group(P<0.05).Conclusion:Color Doppler ultrasound can fully evaluate the carotid plaque and hemodynamics in patients with hypertension,which has guiding significance for clinical early screening and early intervention.
