In patients with chronic kidney disease (CKD), vascular calcification is associated with significant morbidity and mortality. The prevalence of vascular calcification increases as glomerular filtration rate (GFR) declines and calcification occurs years earlier in CKD patients than in the general population. The mechanisms of vascular calcification in CKD patients are complex and not completely understood but likely involve non-traditional risk factors, which may be unique to patients with CKD. These unique risk factors may predispose patients to early and more accelerated calcification. Experimental and clinical studies show that disorders in mineral metabolisms including calcium and phosphorus homeostasis initiate and promote vascular calcification in patients with CKD. It is currently unknown if vascular calcification can be prevented or reversed with therapies aimed at maintaining calcium and phosphorus homeostasis. This review focuses on the potential mechanisms by which disordered mineral metabolism may promote vascular calcification in patients with CKD.
