Similar to previous studies, our study has revealed that increased NLR is associated with factors affecting severity and complexity of atherosclerosis, such as increased age[2,4,12,18], higher preoperative C-reactive protein[10,15,18-20] or lower CrCl[2,9,12,19] levels, increased incidence of peripheral vascular disease or insulin-dependent diabetes mellitus[20] and history of smoking[15]. This evidence concerns the gene CRP and vascular disorder.
