Lower heart rate variability (HRV) in chronic kidney disease (CKD) patients is associated with increased risk of cardiovascular disease (CVD). We aimed to evaluate the relationships between blood bone markers and HRV in stage 5 CKD patients, longitudinal changes in severe secondary hyperparathyroidism (SHPT) subgroup with parathyroidectomy (PTX) were also explored.


This cross-sectional study included 134 CKD patients, 100 controls, and a prospective study in PTX group(n=45) with median follow-up time of 6.7 months. Bone parameters included (1) intact parathyroid hormone (iPTH), as classic bone remodeling regulators; (2) bone-specific alkaline phosphatase (BAP), representing bone formation; (3) tartrate-resistant acid phosphatase (TRACP-5b), indicating bone resorption; (4) bone-derived hormone, fibroblast growth factor 23 (FGF23). HRV were measured by 24h Holter.


Circulating bone markers of the participants were shown in Table 1. Baseline iPTH, BAP and lnFGF23 levels were independently associated with decreased HRV in CKD patients. Elevated blood iPTH, BAP, TRACP-5b, FGF23 levels and attenuated HRV were ameliorated after PTX, furthermore, improved HRV were associated with reduced iPTH, TRACP-5b and FGF23 levels(Fig1).


In CKD patients, circulating iPTH and FGF23 levels may play important roles in imbalances of cardiovascular autonomic nervous system while the roles of bone resorption/formation need more research.
