Objective: To explore the clinical characteristics of traditional Chinese medicine and changes in carotid artery elasticity in young people with anxiety. Method: A total of 78 young people aged 18-35 who visited the Department of Cerebrology at Dongzhimen Hospital from May 2022 to September 2022 were collected as research subjects. Their anxiety status was evaluated, and their carotid intima media thickness and stiffness were evaluated using Esaote MyLab 90 color Doppler ultrasound. According to the Hamilton Anxiety Scale (HAMA) scores, the study subjects were divided into an anxiety group (≥14 points) and a non anxiety group (<7 points). Analyze the general situation, traditional Chinese medicine symptoms, and differences in various parameters of carotid artery elasticity(Carotid artery intima-media thickness QIMT, dilation coefficient DC、dilation coefficient CC、αStiffness、βStiffness、pulse wave conduction velocity) between the two groups of people. Result: There were statistical differences between the two groups in terms of scale scores, carotid intima media thickness, and elasticity parameters (P<0.05). The PSQI and PSS scores of the anxiety group were higher than those of the non anxiety group (P<0.01). The thickness of the right carotid artery intima media in the anxiety group was greater than that in the non anxiety group (P<0.05), and the carotid artery elasticity in the anxiety group decreased compared to the non anxiety group (P<0.01). HAMA score is negatively correlated with bilateral DC and CC, and is correlated with bilateral α、β、 PWV showed a positive correlation (P<0.01); After controlling for related factors such as age, gender, height, weight, BMI, blood pressure, and pulse pressure difference, the HAMA score was negatively correlated with LCC and was negatively correlated with Lα、Lβ、LPWV shows a positive correlation (P<0.05), indicating that young people with anxiety tend to have characteristics such as insomnia, high stress, and poor carotid artery elasticity. As the level of anxiety increases, the carotid artery elasticity of young people gradually deteriorates. There is a statistically significant difference in traditional Chinese medicine symptoms between the two groups (P<0.05). This indicates that young people with anxiety often have characteristics such as insomnia, high stress, and poor carotid elasticity, and as the level of anxiety increases, the carotid elasticity of young people gradually deteriorates. Conclusion: In youth, before arteriosclerosis occurs, anxiety can cause damage to the carotid artery. For young anxiety patients, it is important to relieve stress, improve sleep, and pay timely attention to treatment to protect blood vessels and delay the occurrence and development of arteriosclerosis.
