Although advanced oxidation protein products and visfatin levels do not correlate with disease severity, they appear to be associated with each other (r = 0.6, p < 0.001), but also with ultrasound markers of atherosclerosis, i.e., such as carotid intima-media thickness (r = 0.3, p < 0.05 for advanced oxidation protein products) and flow-mediated dilatation (r = −0.25, p < 0.05 for advanced oxidation protein products; r = −0.25, p < 0.05 for visfatin) [24]. This evidence concerns the gene NAMPT and atherosclerosis.
