SUN-122 NON-DIPPING OF 24 HOUR AMBULATORY HEART RATE PREDICTS ALL-CAUSE MORTALITY IN STAGE 5 CKD PATIENTS AND?THE TREATMENT VALUE OF?PARATHYROIDECTOMY

摘要

Introduction: Chronic kidney disease (CKD) patients are proved at highmortality risk，especially when combined with secondary hyper-parathyroidism(SHPT). It’s revealed that the occurrence of death inhemodialysis patients had circadian rhythm, with highest incidenceduring night and early morning. Under physiological conditions, heartrate (HR) experience a 10-20% decrease and reach their nadir at nightand then increase steeply in the early morning. However, much less isknown about the predictive power of ambulatory HR for all-causemortality in CKD patients. Besides, the treatment value of para-thyroidectomy(PTX) for 24 hour HR indexes in severe SHPT patients isalso uncertain.
