摘　　要：血管硬度是检测亚临床动脉硬化的一个有效的参数,能够很好的表征人体的心血管健康状况。血管弹性扩张系数ETK是心脏收缩排血时动脉血管弹性扩张的程度,通常用来作为计算其它心血管参数的中间变量,本文提出应用ETK直接来评价动脉血管硬化的程度的方法,设计和开发了血压与血管硬度的无创检测系统。临床实验结果表明,血管弹性扩张系数ETK与临床彩超检测结果的相关系数为0.76,证明了该方法的有效性。Arterial stiffness is an effective parameter for monitoring sub-clinical arterial stiffness, and can tell effectively the cardiovascular health status of human body. Elastic expansion coefficient of blood vessel （ETK） is the degree of arterial elastic expansion during systolic ejection, which is often used as the middle variable for calculating other cardiovascular parameters. A new method was proposed to estimate directly the arteriosclerotic degree with ETK, and blood pressure and arterial stiffness non-invasive monitor was designed and developed. Results of clinical experiment showed that the correlation coefficient between ETK and results of clinical ultrasound system is 0.76, which proves the validity of the method.
