Atrial fibrillation and low vitamin D levels are associated with severe vascular calcifications in hemodialysis patients

Background/Aims Vascular calcifications (VCs) and fractures are major complications of chronic kidney disease. Hemodialysis patients have a high prevalence of atrial fibrillation (AF) and an increased risk of thromboembolism, which should be prevented with warfarin, a drug potentially causing increased risk of VCs and fractures. Aim of this study is evaluating, in hemodialysis patients with and without AF, the prevalence of VCs and fractures, as well as identifying the associated risk factors.
