New data suggest that a fall in parathyroid hormone (PTH) 12 months after initiating haemodialysis is associated with cardiovascular death at 12–24 months. The main independent predictor for the fall in PTH is a high dialysate calcium concentration, which might not only reduce PTH but also induce vascular calcification.
Refers to Merle, E. et al. Low parathyroid hormone status induced by high dialysate calcium is an independent risk factor for cardiovascular death in hemodialysis patients. Kidney Int. 89, 666–674 (2016)
