Abstract 409: The Association Between Carotid Artery Plaqus and Cardiovascula Risk Factor in Japanese Individuals

Introduction: Patients with many cardiovascular risk factors develop the carotid artery plaques(CAP) at the early atherosclerotic change. In this study, we performed the comparison between the individuals with CAP and without CAP and investigated the characteristics of cardiovascular risk factors. Subjects and methods: A total of 310 individuals matched-age(mean age 67.6± 3.7 years) underwent the comprehensive health examination such as Body mass index(BMI), AIP75, blood pressure(BP), Sodium ingestion, Pulse wave velocity(PWV) and serum data. Carotid artery ultrasound was done to all individuals and CAP and the intima-media thickness(IMT) were shown. Results: The prevalence of CAP was 20%(62/310) and that of CAP in men and women was 24.6%(35/142) and 16.1%(27/168), respectively. PWV and IMT of the individuals with CAP (CAP group) was significantly higher, compared with those without CAP (not CAP group). BMI and sodium ingestion of CAP group was significantly lower, compared with those of not CAP group. In addition, systolic BP and G-GTP of CAP group showed the high tendency (p=0.085, p=0.056, respectively) and diastolic BP and HDL-C of CAP group showed the low tendency (p=0.097, p=0.052, respectively), compared with those of not CAP group. PWV of CAP group in man was significantly higher, compared with that of not CAP group in man. However, HDL-C of CAP group in woman showed the low tendency, compared with that of that of not CAP group in woman. Conclusion: It has been suggested that the development of CAP is associated with the cardiovascular risk factor such as PWV, IMT, HDL-C , G-GTP and BP.
