Abstract:

Objective

To investigate the correlation between carotid intima-media thickness (CIMT) and cardio-ankle vascular index (CAVI) in hypertension subjects.

Methods

A total of 324 subjects in Department of Vascular Medicine, Peking University Shougang Hospital were enrolled into our study, and they were divided into two groups based on blood pressure levels: control group (173 cases) and hypertension group (151 cases). Two-dimensional ultrasound and VS-1000 were used to measure CIMT and CAVI.

Results

The prevalence of coronary artery disease and stroke was significantly higher in the hypertension group than in the control group (P<0.05). The levels of CIMT and CAVI were significantly higher in the hypertension group than in the control group [(0.62±0.23) mm vs (0.51±0.22) mm and 8.40±1.51 vs 7.46±1.10, respectively, P<0.001 ]. There was a positive correlation between CIMT and CAVI in hypertension subjects (r=0.191, P<0.05). Multivariate analysis showed that age and systolic blood pressure were independent risk factors for CIMT in hypertension subjects (β=0.253, P=0.004; β=0.283, P=0.001).

Conclusion

CIMT is significantly higher and positively correlated with CAVI in hypertension subjects, indicating the role of CIMT in predicting arteriosclerosis.
