Cardiovascular calcification is probably the main reason for the high prevalence of cardiovascular diseases in chronic kidney disease patients Studies have shown that hyperphosphatemia is associated with increased vascular stiffening and arterial and valvular calcification This is postulated to be caused by elevated serum phosphorus promoting the transformation of vascular smooth muscle cells into an osteoblast phenotype that can mineralize These vascular calcification also lead to left ventricular hypertrophy by decreasing vascular compliance . Poor control of mineral metabolism also has been associated with functional and structural cardiac abnormalities Efforts to reduce morbidity and mortality associated with Chronic Kidney Disease-Mineral and Bone Disorder are therefore primarily directed at controlling hyperphosphatemia via diet, phosphorus binders, and dialysis
