E-tracking技术对妊娠期高血压疾病患者颈动脉弹性功能的研究

E-Tracking Technique in Evaluations of Carotid Artery Elasticity in Patients with Hypertensive Disorders Complicating Pregnancy

目的:探讨血管回声跟踪(E-Tracking,ET)技术评价妊娠期高血压疾病患者颈动脉弹性功能的改变。材料与方法:对妊娠期高血压疾病患者(孕28周后)49例和66例正常妊娠期孕妇(孕28周后)进行双侧颈总动脉血管弹性指标的测量:弹性模量(Eρ)、僵硬度(β)、顺应性(AC)、膨大指数(AI)和脉搏波传导速度(PWVβ),并进行统计学分析。结果:妊娠期高血压疾病组双侧颈总动脉Eρ、β、AC及AI较对照组升高,AC较对照组减低,具有显著性差异(P<0.05,P<0.01)。结论:血管回声跟踪技术能较早、明确的反映妊娠期高血压疾病患者颈动脉弹性功能的改变,具有一定价值。

Purpose： To expiore the change of Carotid Artery Elasticity in Patients with Hypertensive Disorders Complicating Pregnancy by ET Technique. Materials and Methods： 49 cases of hypertensive disorders complicating pregnancy （ after 28 weeks of gestation） and 66 cases of normal pregnancy women（ after 28 weeks of gestation） were selected. The elastic coefficient（ Ep）, stiffness parameter（β） , arterial compliance（ AC）, augment index（ AI ） , and one point pulse wave velocity（PWVβ） of bilateral common carotid artery were measured by ET techniques. Results： Ep, 6, AI, PWVβ were noted to increase in pregnancy group than those in control group, while AC was noted to decrease （P 〈 0. 05, P 〈 0. 01 ）. Conclusion ： E - tracking technology can precisely reflect Carotid Artery Elasticity in Patients with Hypertensive Disorders Complicating Pregnancy, having a certain value.
