Cardiovascular and fracture events analysis and intervention strategies in patients undergoing parathyroidectomy with secondary hyperparathyroidism.

Abstract

Chronic kidney disease (CKD), especially end-stage renal disease (ESRD), is the most common cause of secondary hyperparathyroidism (SHPT), and SHPT is the most severe complication of ESRD. This study aimed to analyze the influencing factors of cardiovascular and fracture events in patients with SHPT which are the leading causes of death in patients with CKD, and provide a reference for selecting patients for whom surgery is more suitable. Patients who underwent parathyroidectomy (PTX) for SHPT at The First Affiliated Hospital, Zhejiang University School of Medicine from September 2021 to April 2024 were selected as the study object, with the inclusion and exclusion criteria as followed. They were divided into rural and urban residents for comparison as a cross-sectional study. The study evaluated the comorbidities, socioeconomic status, and postoperative complications diagnosed by radiography of patients undergoing surgery for SHPT. A total of 119 patients were included, among whom, 71 were from rural areas and 48 were from urban areas. Compared with urban residents, rural residents had poorer economic conditions, a longer interval from disease onset to PTX, and a higher incidence of cardiovascular and fracture events and concurrent nephrolithiasis, all of which were statistically significant. Multivariate analysis indicated that place of residence, age, and duration of uremia were independent risk factors of cardiovascular/fracture events. Medical staff in ESRD outpatient clinics should pay attention to patients with SHPT. ESRD patients should have better surveillance especially for rural, elder and poor phosphorus control patients, and promptly assess surgical intervention measures.
