Abstract

Aims/Background Pulmonary arterial hypertension (PAH) is a significant contributor to increased overall and cardiovascular mortality in peritoneal dialysis (PD) patients. Cardiopulmonary exercise testing (CPET) is an accurate method for measuring cardiorespiratory fitness (CRF) during both submaximal and peak exercise. Previous studies have demonstrated a strong correlation among CRF and increased cardiovascular and overall mortality rates. However, no literature currently reports the predictive value of CPET parameters for PAH occurrence in PD patients. This study primarily aims to analyze the risk factors for PAH in PD patients, assess the predictive value of CPET parameters, and provide a reference for the clinical prevention and management of PAH. Methods The clinical data of 121 PD patients who underwent CPET were retrospectively collected at Xuzhou Medical University Affiliated Hospital. Based on the event of PAH, patients were divided into two groups: a PAH group (n = 39) and a non-PAH group (n = 82). Clinical data, laboratory results, ultrasound findings, and CPET parameters were compared between the groups. Multifactorial logistic regression analysis was performed to identify the risk factors for PAH. The predictive value of CPET parameters was evaluated by calculating the area under the receiver operating characteristic (ROC) curve (AUC) using ROC curve analysis. Results White blood cell count (WBC) was an independent risk factor for PAH in PD patients (p < 0.05). VO2peak (peak oxygen uptake), VO2AT (anaerobic threshold oxygen uptake), METspeak (peak metabolic equivalents), WRpeak (peak power load) were identified as protective factors for PAH in PD patients (p < 0.05). ROC curve analysis showed that the AUC values for predicting PAH in PD patients using VO2peak, VO2AT, METspeak, and WRpeak were 0.675, 0.651, 0.719, and 0.689, respectively, with METspeak demonstrating the highest AUC for prediction. Conclusion The occurrence of PAH in PD patients is associated with WBC, VO2peak, VO2AT, METspeak, and WRpeak. Additionally, CPET parameters exhibit predictive value for PAH, with METspeak showing the highest AUC for prediction.

期刊介绍: British Journal of Hospital Medicine was established in 1966, and is still true to its origins: a monthly, peer-reviewed, multidisciplinary review journal for hospital doctors and doctors in training. The journal publishes an authoritative mix of clinical reviews, education and training updates, quality improvement projects and case reports, and book reviews from recognized leaders in the profession. The Core Training for Doctors section provides clinical information in an easily accessible format for doctors in training. British Journal of Hospital Medicine is an invaluable resource for hospital doctors at all stages of their career. The journal is indexed on Medline, CINAHL, the Sociedad Iberoamericana de Información Científica and Scopus.
