BACKGROUND: The purpose of this study was to investigate the elasticity of large and small arteries in relation to the components of the metabolic syndrome in a Chinese population. METHODS: Arterial elasticity indices were derived from pulse wave analysis based on a modified Windkessel model in 688 subjects, aged 33-65 years, who volunteered to participate in our study. RESULTS: The study population included 420 (61.0%) men and 433 (62.9%) hypertensive patients, of whom 197 (28.6%) took antihypertensive medication. Overall, the presence of the metabolic syndrome was 20.5%. In univariate analysis, both large artery elasticity index (C1) and small artery elasticity index (C2) were higher in men than in women (P < or = 0.008) and were inversely (P < or = 0.05) correlated with age, systolic and diastolic blood pressure (BP), pulse pressure, pulse rate, and plasma glucose concentration, and positively (P < 0.0001) correlated with body height and body weight. In men, smokers, compared with nonsmokers, had significantly lower C2 (P = 0.007), but they had similar C1 (P = 0.33). In adjusted analysis, patients with the metabolic syndrome, compared with those without, had significantly (P < 0.01) lower C1 and C2. In continuous adjusted analysis, both C1 and C2 were significantly (P < 0.0001) associated with systolic and diastolic BP, whereas in addition, C1 was also significantly associated with plasma glucose concentration (P = 0.007), and C2 with serum high-density lipoprotein (HDL) cholesterol (P = 0.02). CONCLUSIONS: The metabolic syndrome is indeed a risk factor for reduced arterial elasticity.
