血管回声跟踪技术评价 HAART 治疗后艾滋病患者颈动脉弹性

目的：应用血管回声跟踪技术（ET）检测艾滋病患者高效抗反转录病毒疗法（HAART）治疗后颈动脉弹性，探讨 ET 对艾滋病患者 HAART 治疗后预防颈动脉粥样硬化的指导价值。方法：应用血管回声跟踪技术跟踪描记 HAART 治疗后艾滋病患者50例及健康志愿者30例颈总动脉（CCA）的运动轨迹，测量其僵硬度（β），弹性系数（Ep），顺应性（AC）以及脉搏波传导速度（PWVβ），并测量颈动脉内-中膜厚度（IMT）。结果：HAART 治疗后艾滋病患者较健康志愿者测量颈动脉 IMT 稍增厚，但差异无明显统计学意义；β，Ep 以及 PWVβ均增高，AC 降低，差异均有统计学意义。结论：血管回声跟踪技术可评价艾滋病患者 HAART 治疗后颈动脉粥样硬化的早期改变。

Vascular Echo Tracking Technology Evaluation HAART Treatment of AIDS Patients with Carotid Artery Elasticity

Objective: To apply vascular echo tracking technology (ET) detection in highly active anti-retroviral therapy( HAART ) treatment of HIV/AIDS patients carotid artery elasticity and discuss its guidance value in HIV/AIDS patients after receiving HAART treatment prevention cervical atherosclerosis . Methods: Intima-Media Thickness of Carotid Arteries thick-ness (IMT) were measured and ET was used in common carotid artery (CCA) trajectory between 50 cases of HIV/AIDS patients after receiving HAART treatment and 30 cases of healthy volunteers, measuring its stiffness (β), modulus of elasticity (Ep) and compliance (AC) and pulse wave conduction velocity (PWVβ).Results: carotid IMT in HIV/AIDS patients after receiving HAART treatment were more thick than healthy volunteers , but there was no obvious statistical significance. But theβ, Ep and PWVβ increased, and AC reduced when compared with control group. Conclusion: ET to evaluate an early change in carotid atherosclerosis in AIDS patients after receiving HAART treatment.
