Metabolic Syndrome, Inflammation, and Risk of Symptomatic Peripheral Artery Disease in Women A Prospective Study


Background—The metabolic syndrome (MetS) is associated with incident myocardial infarction and stroke and is linked with subclinical inflammation; however, prospective data pertaining to MetS and future peripheral artery disease (PAD) are sparse, with few studies examining the role of inflammation. We therefore evaluated the relationship between MetS, inflammation, and incident PAD. Methods and Results—We conducted a prospective cohort study among 27 111 women free of baseline cardiovascular disease who were participating in the Women’s Health Study. Subjects were followed for incident symptomatic PAD (n114; median cohort follow-up 13.3 years). We used Cox proportional hazards models to compare PAD risk among women with and without MetS. We also evaluated relationships between MetS and subclinical inflammation as measured by high-sensitivity C-reactive protein and soluble intercellular adhesion molecule-1 and adjusted for these biomarkers in multivariable models. Women with MetS had a 62 % increased risk of future PAD (hazard ratio 1.62, 95% confidence interval 1.10 to 2.38). After multivariable adjustment, MetS remained significantly associated with PAD (adjusted hazard ratio 1.48, 95 % confidence interval 1.01 to 2.18), with a 21 % risk increase per additional MetS-defining trait (adjusted hazard ratio 1.21, 95 % confidence interval 1.06 to 1.39). In women with and without MetS, respectively, median levels of high-sensitivity C-reactive protein were 4.0 versus 1.5 mg/L (P0.0001), and median levels of soluble intercellular adhesion molecule-1 were 374 versus 333 ng/mL (P0.0001). When high-sensitivity C-reactive protei
