Clinical Trial Summary

This study intends to establish the normal reference values of carotid artery intima-media thickness and vascular elasticity of Chinese adults based on ultrasound radio frequency technology through a multi-center large-sample study, which provides important information for the risk prediction and prognosis evaluation of Chinese adults' cardiovascular disease.

Description:

After being informed about the study, all participants giving written informed consent will undergo a one-time examination of vascular ultrasound, including general characteristics and the target ultrasound parameters.

To detect the smallest difference between adjacent age groups within the age range 18-79 (6 groups, α = 0.05, β = 0.20, Statistical Power = 0.80). Given the influence of multiple centers, the minimum sample size is 1800, the optimal sample size is 3500. The male to female ratio is 1:1.

Quality Control including the pre-study training and data monitoring during the study.
