Background: The treatment effects of rosuvastatin on arterial stiffness were assessed and compared to those of fluvastatin in high-risk Japanese patients with dyslipidemia in a primary prevention group. Methods and Results: Patients were randomly assigned to either 2.5-5 mg/day of rosuvastatin (Group A) or 20- 40 mg/day of fluvastatin (Group B) and followed up for 12 months. In Group A (n=38), there was a progressive reduction in brachial-ankle pulse wave velocity (baPWV) along with a decrease in the low-density lipoprotein cholesterol/ high-density lipoprotein cholesterol (L/H) ratio and high-sensitivity C-reactive protein (hsCRP), and the change in baPWV correlated significantly with that of the L/H ratio and that of hsCRP after rosuvastatin treatment. In Group B (n=37), although fluvastatin achieved a significant improvement in baPWV, L/H ratio, and hsCRP, baPWV was significantly greater than that in Group A and showed a significant correlation with that of hsCRP alone after fluvastatin treatment. In a subgroup of patients (n=26), switching from fluvastatin to rosuvastatin further improved baPWV and the L/H ratio without altering hsCRP after 12 months. Conclusions: Low-dose rosuvastatin would be more effective than fluvastatin in improving arterial stiffness in highrisk Japanese patients with dyslipidemia. The results suggest that improvement in arterial stiffness by rosuvastatin mainly depends on its strong lipid-lowering effects, whereas that by fluvastatin is strongly dependent on the pleiotropic effects, especially an anti-inflammatory action.

Background: The present study was designed to examine whether serum uric acid (SUA) levels were associated with cardiometabolic risk factors and to determine optimal cut-offs for SUA to identify multiple risk factors among Japanese junior high school students.&Methods and Results: A total of 958 students (518 boys and 440 girls, aged 12.1-15.0 years) who were enrolled between April 2005 and June 2008 were divided into 4 groups according to SUA quartiles. Compared with the lowest quartile of SUA, prevalence of abdominal obesity, hypertension, and dyslipidemia was significantly increased in the highest quartile in boys and that of abdominal obesity was increased in the highest quartile in girls. The adjusted odds ratios (95% confidence interval) of the highest quartile of SUA for 2 or more cardiometabolic risk factors were 2.59 (1.16-5.79) for boys and 1.54 (0.43-5.56) for girls. Receiver operating characteristic curve analysis demonstrated that the most appropriate cut-offs for SUA to identify multiple cardiometabolic risk factors were 6.4mg/dl for boys and 4.9mg/dl for girls.&Conclusions: SUA was strongly associated with the prevalence of cardiometabolic risk factors among male Japanese junior high school students. The present study may provide insights into the role of SUA in the school screening system for the development of educational programs on prevention of lifestyle-related diseases among school children.
