Objectives: The cardio-ankle vascular index (CAVI) and ankle-brachial index (ABI) are non-invasive methods to evaluate cardiovascular disease and arteriosclerosis. This study investigated the relationship between CAVI, ABI, and factors related to arteriosclerosis. Methods: This study included 535 healthy adults who underwent health examinations in 2019. We analyzed the correlation between CAVI, ABI and clinical variables. Multiple regression analysis was performed on the independent clinical variables associated with CAVI and ABI. Results: The correlation analysis of CAVI showed that body mass index (BMI) and HDL-cholesterol (HDL-C) had a negative correlation, and the other variables had a significant positive correlation. The correlation analysis with ABI on the right side showed that age, diastolic blood pressure (DBP), gender, and LDL-cholesterol (LDL-C) had a significant positive correlation, while HDL-C had a significant negative correlation. There was no statistical significance on the left. In the multiple regression analysis, DBP, age, BMI, gender, and HDL-C were proved to be independent factors in CAVI (right) (R²=0.365); DBP, age, gender, BMI, fasting blood sugar, and total cholesterol in CAVI (left) (R²=0.357); and age, gender, DBP, and systolic blood pressure in ABI (right) (R²=0.133). There were no statistically significant factors in ABI (left). It could be inferred that smoking and drinking are determinants that play an important role in CAVI. Conclusion: CAVI showed a high correlation with gender, age, and blood pressure. A significant correlation between CAVI and serum lipid values could be observed, but this showed a low correlation coefficient. ABI showed a high correlation with age and DBP. These results support the use of CAVI and ABI as primary diagnostic devices in medical treatment.

Backgrounds: Blood stasis is hon as an important pathologic factor for vascular disorder in Oriental medicine. Despite its clinical importance there have been few objective tests for diagnosing blood stasis. Objectives: This study was designed to examine the relationship between blood stasis and arterial stiffness measured by cardio-ankle vascular index (CAVI). Methods: The subjects were 104 ischemic stroke patients with onset after 14 days. Their general characteristics, lipid profiles and uric acid were recorded. The degree of arterial stiffness was assessed by CAVI, and blood stasis was evaluated by diagnostic criteria. The data were analyze4 by chi-square test, student t-test, spearman correlation analysis, and pearson correlation analysis. Then, stepwise multiple logistic regression analysis was applied in order to exclude the interactions among several factors. Results: There were significant differences in right, left and higher CAVI between the blood stasis group and the non blood stasis group (p-value<0.01). Age, systolic blood pressure, triglyceride and CAVI had relationships with blood static scores. In multiple logistic regression analysis, the adjusted odds ratio of blood stasis for arterial stiffness with CAVI above 9 were 7.091 (95% confidence interval, $1.641\sim30.638$). Conclusions: The results demonstrated the relationship between blood stasis and arterial stiffness measured by CAVI. Therefore, we suggest that CAVI should be one of the objective tests for diagnosing blood stasis.

Objectives : Uwhangchungsimwon (UC) is one of the famous herbal medicine frequently used for stroke, hypertension, and atherosclerosis, etc. Therefore, we intended to examine if UC could have therapeutic effect on arterial stiffness by assessing Cardio-Ankle Vascular lndex (CAVI). Methods : We enrolled 38 healthy male subjects (28±4.41 years old) and divided them into two groups (UC and control group). The UC group (N=22) were treated with 1 pill of UC and monitored by CAVI every hour for 6 hours. The control group(N=16) did not receive any medicine and were also monitored by CAVI the same manner as the UC group. In both group, we also assessed each subject's Yin-Yang pattern score by the diagnostic scoring system. In analysis, we compared the difference of CAVIs between the UC and the control group considering subject's Yin-Yang pattern. Results : There was no significant difference in the change of CAVI between the UC and the control group. After excluding Yang-pattern subjects in both group, however, we could observe that CAVI decreased significantly 5 hours after UC administration compared with the corresponding CAVI in the control group (P=0.025). In the repeated measure analysis, the between-subjects effect had statistical significance (P=0.035). Conclusion : According to these results, we suggest that UC have therapeutic effect on arterial stiffness especially after taking oriental medical diagnosis into consideration.

The object of this study was to examine the relationship between arteriosclerosis and oriental medical diagnosis of the patients who had suffered ischemic stroke. The degree of arteriosclerosis of the patients was assessed by cardio-ankle vascular index(CAVI), and diagnostic criteria used for all patients were deficiency of ki, deficiency of blood, blood stasis and stagnation of water. One hundred four patients were included and their general characteristics, CAVI and oriental diagnosis were evaluated. Results showed a significantly strong correlation between CAVI and blood stasis. These results suggest a close relationship between arterioslcerosis and blood static syndrome as defined by oriental medicine. If so, diagnosis of blood static syndrome is a reilable predictor of arteriosclerosis.

Objectives: Electroacupuncture according to Voll (EAV) has been used to quantify the skin's electrical resistance and conductance over acupuncture points that, based on traditional Chinese medicine, represent the state of health or disease of the organ or tissue. However, it doesn't have enough objective data yet, so the purpose of this study was to aid in the use of EAV in analysis of cerebrovascular disease risk factors. Methods: This study researched the clinical statistics of 216 cases: cerebrovascular attack (CVA) group 43, control group 173. We measured control meridian points (CMP) on hands and feet and the cardio ankle vascular index (CAVI) which represents atherosclerosis severity, and sex, age, hypertension, diabetes, dyslipidemia, and obesity. The data were then analyzed by t-test, chi-square test and logistic regression. Results: Between the CVA and control groups, there were not statistically significant differences in CMP. However, logistic regression analysis of the presence of CVA, mean of CMP heart and lung, sex, age, DBP (diastolic blood pressure), and HDL (high density lipoprotein) cholesterol showed that the risk of CVA was 1.1 times increased with CMP heart (p=0.002), in men was 4.12 times higher than in women (p=0.001), 1.09 times higher with age (p=0.000), 1.04 times higher with DBP (p=0.045), while was lower by 0.924 times with CMP lung (p=0.005) and 0.957 times with HDL cholesterol (p=0.006). Conclusion: Although there were not clear evidence or mechanisms about EAV, this study showed that if we study EAV further, we may be able to apply EAV as an objective instrument of oriental medicine in cerebrovascular disease.
