Hyperphosphatemia or abnormally high serum phosphate levels, has been identified as a key factor associated with cardiovascular complications and increased mortality risk among patients with chronic kidney disease (CKD). Hyperphosphatemia is a late consequence of advanced CKD — defined as having a glomerular filtration rate (GFR) < 30 mL/min — and has been linked to morbidities including vascular calcification, mineral bone disease, and hyperparathyroidism. Observational studies among dialysis cohorts have repeatedly linked high circulating phosphate to reduced survival. Consequently, the Kidney Disease Improving Global Outcomes (KDIGO) guidelines recommend monitoring serum phosphorus levels at consistent intervals, and lowering elevated levels towards the normal range in patients with CKD.
