INTRODUCTION: This study aimed to analyze the correlation between blood pressure variability (BPV), crystalloid osmotic pressure, and cardiovascular events (CEs) in patients undergoing maintenance hemodialysis (MHD).
METHODS: This retrospective analysis was conducted on 71 patients with end-stage kidney disease who underwent hemodialysis at Beilun District People's Hospital from September 2021 to September 2022. The patients were divided into two groups based on the occurrence of CEs: a cardiovascular event group and a non-cardiovascular event group.
RESULTS: The 71 patients were divided into two groups based on the occurrence of CEs: the CEs group (25 patients who experienced CEs) and the non-CEs group (46 patients who did not experience CEs). The CEs group had significantly higher levels of crystalloid osmotic pressure, standard deviation of systolic BP (SBP-SD), coefficient of variation of SBP (SBP-CV), SD of diastolic BP (DBP-SD), and DBP-CV (P < .05). Multivariate logistic regression analysis identified crystalloid osmotic pressure, SBP-CV, and DBP-CV as independent risk factors for CEs. The ROC curve analysis indicated that the combined predictive value of crystalloid osmotic pressure, SBP-CV, and DBP-CV was significant, with an area under the curve (AUC) of 0.963.
