In order to provide reference for early prevention and treatment of cardiovascular diseases, the correlation between rheumatoid arthritis and arterial elasticity in the elderly was studied by using echo tracking technique. Objectives 40 elderly patients with rheumatoid arthritis and 40 healthy elderly people aged 60 to 79 were selected as experimental group and control group. The intima-media thickness and elasticity parameters of carotid and brachial arteries were measured by ALOKA Prosound alpha 10. The results showed that the IMT value of carotid artery was more than 1 mm in 35 patients with rheumatoid arthritis and more than 1 mm in 31 healthy subjects. There was no significant difference between the experimental group and the control group (p > 0.05). There were significant differences in the IMT value of brachial artery between the experimental group and the control group (p < 0.05, P < 0.01). There were significant differences between the two groups (p > 0.05), and there were significant differences between the two groups (p < 0.05). The results of ROC curve analysis showed that there were significant differences in the parameters of arterial elasticity between the two groups (p < 0.05). It can be seen that there is a significant correlation between rheumatoid arthritis and the elasticity of carotid and brachial arteries in the elderly. However, due to the influence of age, the change of IMT value of arteries can not reflect the statistical correlation between RA and atherosclerosis. According to the experimental results, ET technology can be used as an early diagnostic method to detect the decline of arterial elasticity in RA patients to prevent cardiovascular diseases.
