Vascular Calcification in Chronic Kidney Disease

Pathophysiological Mechanisms and Clinical Significance

• In patients with chronic kidney disease, hyperphosphatemia leads to secondary hyperparathyroidism, which can cause vascular calcification, according to the American Journal of Kidney Diseases 1
• Prolonged hyperphosphatemia causes soft-tissue and vascular calcification due to increased calcium-phosphate product, associated with increased morbidity and mortality in CKD patients, as reported by the American Journal of Kidney Diseases 1
• Vascular calcification in CKD is a complex multisystem disease requiring modification of multiple parameters, as stated by Kidney International 3, 4
• The National Kidney Foundation recommends maintaining serum phosphorus levels between 3.5-5.5 mg/dL to prevent secondary hyperparathyroidism and its complications, including vascular calcification, based on guidelines from the American Journal of Kidney Diseases and Kidney International 1, 3
• The American Journal of Kidney Diseases suggests that the calcium-phosphate product should be maintained below 55 to reduce the risk of vascular calcification 5
