CRP and atherosclerosis: Our finding is consistent with that of previous reports of an association of traditional and emerging risk factors with abnormal ABI as a marker of atherosclerosis in the general population as well as in chronic hemodialysis patients.10,20,21 Increased calcium levels and phosphocalcic product, a marker of mediacalcosis, have already been reported in chronic hemodialysis patients with abnormal ABI or incompressible ankle by Miguel10 and Van Jaarsveld.22 Patients with abnormal ABI had increased levels of C-reactive protein as an inflammation biomarker in the present study.
