NCT04881292

Brief 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.
