Plasma Parathyroid Hormone Level and Prevalent Cardiovascular Disease in CKD Stages 3 and 4: An Analysis From the Kidney Early Evaluation Program (KEEP)

PTH level greater than 70 pg/mL is independently associated with CVD events in patients with CKD stages 3 and 4. No association was observed between serum phosphorus or calcium level and CVD events. These findings provide support for intact PTH testing, along with testing for other indicators of CKD mineral and bone disorders, at earlier CKD stages.
