Department of Ultrasound, North China University of Science and Technology Affiliated Hospital, Tangshan Hebei 063000, China随着社会的进步、人们生活方式及环境因素的不断改变,我国高血压的发病率呈现迅猛增长的趋势。高血压作为动脉粥样硬化的重要危险因素,其早期动脉改变即为动脉弹性减低。血管回声跟踪(Echo-Tracking,ET)技术是研究大动脉弹性的超声新技术,能在动脉形态学改变(即内中膜增厚、斑块形成)之前更早、更准确地定量评价动脉弹性功能的改变,反映动脉硬化的程度,是评价早期动脉硬化简便实用的方法
Abstract:Objective To explore the effectiveness of application of ET (Echo Tracking) in assessment of changes in carotid artery elasticity between pre- and post-treatment of mild to moderate hypertension patients. Methods Altogether 154 cases of mild to moderate hypertension patients who had accepted individualized treatment with antihypertensive drugs in the hospital from January 2012 to January 2014 were selected. After treatment for three consecutive months, their blood pressure had been decreased to ≤140/90 mmHg. The ET technique was used to detect carotid artery elasticity parameters before and after treatment, including stiffness index (β), pressure elastic coefficient (Ep), artery compliance (AC) and pulse wave velocity (Pwvβ) so as to analyze their changes before and after treatment. Results The decreasing β, Ep and Pwvβ as well as increasing AC were revealed after treatment of mild to moderate hypertension patients, which were statistically significant differences (P<0.05). Conclusion The carotid artery elasticity was somewhat improved in mild to moderate hypertension patients after treatment. The ET technique demonstrated its advantages in accurate detection of changes in carotid artery elasticity before and after treatment of patients with mild to moderate hypertension, which provided guidance for clinical treatment of the diseases and prevented the occurrence of atherosclerosis in an early stage.
