The metabolic syndrome was associated with 11.2% and 17.0% less distensibility and 9.0% and 18.2% less compliance of the carotid and femoral arteries compared to those without risk factors.

Is the metabolic syndrome associated with increased arterial stiffness independently of cardiopulmonary fitness and subcutaneous trunk fat in young adults?
The metabolic syndrome is associated with increased arterial stiffness in young adults, an effect that is partly independent of cardiopulmonary fitness and subcutaneous trunk fat.
BACKGROUND: The mechanisms that link the metabolic syndrome to increased cardiovascular risk are incompletely understood, especially in young people. We therefore examined whether the metabolic syndrome was associated with arterial stiffness and whether any such associations were independent of cardiopulmonary fitness and subcutaneous trunk fat. METHODS: Cross-sectional analyses of data on 364 men and women aged 36 years from the Amsterdam Growth and Health Longitudinal Study (ninth follow-up measurement, year 2000). The prevalence of the metabolic syndrome was defined by a slightly modified National Cholesterol Education Program (NCEP) definition. Arterial stiffness was ultrasonically estimated by distensibility and compliance of the carotid, femoral, and brachial arteries and by the carotid elastic modulus. RESULTS: The prevalence of the metabolic syndrome in this young adult population was 18.3% in men and 3.2% in women. Individuals with the syndrome compared with individuals without risk factors had 11.2% and 17.0% less distensibility and 9.0% and 18.2% less compliance of the carotid and femoral arteries, respectively, and 15.9% higher carotid elastic modulus. After adjustment for cardiopulmonary fitness and subcutaneous trunk fat, the metabolic syndrome remained significantly associated with stiffness of the carotid but not the femoral artery. In addition, poor cardiopulmonary fitness and high subcutaneous trunk fat were associated with arterial stiffness, and this was independent of the metabolic syndrome. CONCLUSIONS: A modified NCEP definition of the metabolic syndrome identified young individuals with increased arterial stiffness. The mechanisms that link the metabolic syndrome, poor cardiopulmonary fitness, and high subcutaneous trunk fat to greater arterial stiffness overlap but are partly independent of each other.
Ferreira et al. (2005) conducted a cross-sectional in Metabolic syndrome (n=364). Metabolic syndrome vs. No risk factors was evaluated on Arterial stiffness estimated by distensibility and compliance of the carotid, femoral, and brachial arteries and by the carotid elastic modulus. The metabolic syndrome was associated with 11.2% and 17.0% less distensibility and 9.0% and 18.2% less compliance of the carotid and femoral arteries compared to those without risk factors.
