GW28-e0619 The Clinical Study of Noninvasive Evaluation of Carotid Arterial Elasticity with Ultrasound RF-based Technique

Methods 160 participants (46 in control group and 114 in atherosclerotic high risk group) were detected the compliance coefficient (CC) ,distensibility coefficient (DC) ,α stiffness coefficient (α),β stiffness coefficient (β) and single point pulse wave velocity (PWV). Evaluation methods and indexes are as follows, (1) the relationship between IMT and arterial wall elastic parameters, (2) the difference of arterial wall elastic parameters in participants with IMT＜1.0mm, (3) the difference of arterial wall elastic parameters in participants with IMT＜1.0mm grouping with the number of risk factors, (4) the independent affecting factors of arterial wall elastic parameters.
