AIM: To evaluate progression of arteriosclerosis using cardio-ankle vascular index(CAVI) and carotid duplex ultrasonography(DUS) in young and adolescent patients considered to be at risk of cardiovascular disease. METHODS: We evaluated the progression of arteriosclerosis using CAVI and carotid DUS in 240 young and adolescent patients. Dyslipidemia(DL), hypertension(HT), and diabetes mellitus(DM) were major cardiovascular risk factors. Patients were divided to 4 groups according to number of risk factors. RESULTS: In terms of risk factors, CAVI and CAVI difference(CAVI-D) were elevated only in the HT group(p=0.0290, p=0.0243 vs. no risk respectively). CAVI-D was positively associated with diastolic blood pressure(DBP). Mean IMT was positively associated with LDL-C or systolic blood pressure, and negatively with HDL-C. Plaque score was associated with LDL-C or DBP. In patients with the 3 risk factors, CAVI, CAVI-D and mean intima-media thickness(IMT) were significantly higher than in those without risk(p=0.0009, p=0.0042 and p=0.0151 respectively), and CAVI and CAVID were higher than in those with 1 risk(p=0.0204 and p=0.0231). Carotid plaque develops from around 30 years of age in Japan. Despite numbers of risk factors, there were no differences in CAVI, CAVI-D, mean IMT or plaque score between smoker and non-smoker groups. CONCLUSION: In conclusion, an increase in the number of risk factors also results in progression of arteriosclerosis in young and adolescent patients. HT was the most important risk factor for arteriosclerosis in these patients.
