VCAM1 and peripheral arterial disease: Furthermore, the PAD group had lower systemic antioxidant capacity measured by hydroxyl radical antioxidant capacity activity (P < 0.001), higher inflammatory and vascular measures of high-sensitivity C-reactive protein (P < 0.001), interleukin-8 (P < 0.001), serum amyloid A (P < 0.001), vascular cell adhesion molecule-1 (P < 0.001), adiponectin (P < 0.001), apolipoprotein B (P = 0.013), apolipoprotein CIII (P = 0.035), lower vascular endothelial growth factor-A (P < 0.001), and hepatocyte growth factor (P < 0.001) than the control group.
