Abstract

Objective: We used our established database to investigate predialysis blood pressure (BP) measurements at different time points.

Methods: Our study period spanned from 1 January 2019 to 31 December 2019. The different time points included: the long interdialytic interval versus the short interdialytic interval; different hemodialysis shifts. Multiple linear regression was used to explore the association between BP measurements and different time points.

Results: A total of 37 081 cases of hemodialysis therapies were included. After a long interdialytic interval, predialysis SBP and DBP were significantly elevated. Predialysis BP was 147.72/86.73 mmHg on Monday and 148.26/86.52 mmHg on Tuesday, respectively. Both predialysis SBP and DBP were higher in the a.m. shift. The mean BP in the a.m. and p.m. shifts were 147.56/87 mmHg and 144.83/84.64 mmHg, respectively. In both diabetic nephropathy and non-diabetic nephropathy patients, higher SBP measurements after a long interdialytic interval were observed; however, in diabetic nephropathy patients, we did not find significant differences in DBP among different dates. In diabetic nephropathy and non-diabetic nephropathy patients, we observed that the effect of different shifts on BP was similar. In Monday, Wednesday and Friday subgroups, the long interdialytic interval was also associated with BP; however, in Tuesday, Thursday and Saturday subgroups, different shifts but not the long interdialytic interval was associated with BP.

Conclusion: The long interdialytic interval and different hemodialysis shifts have a significant effect on predialysis BP in patients with hemodialysis. When interpreting BP in patients with hemodialysis, different time points is a confounder.

不同的时间点,不同的血压:血液透析患者血压测量的复杂性。
目的:我们使用我们建立的数据库来研究不同时间点的分析前血压(BP)测量结果。方法:我们的研究期为2019年1月1日至2019年12月31日。不同的时间点包括:长的分析间隔与短的分析间隔;不同的血液透析转变。多元线性回归用于探索BP测量值与不同时间点之间的关联。结果:共37 纳入血液透析治疗081例。在较长的分析间隔后,分析前SBP和DBP显著升高。透析前血压为147.72/86.73 周一和148.26/86.52毫米汞柱 毫米汞柱。早班分析前SBP和DBP均较高。早班和晚班的平均血压为147.56/87 mmHg和144.83/84.64 mmHg。在糖尿病肾病和非糖尿病肾病患者中,在长的分析间隔后观察到较高的SBP测量值;然而,在糖尿病肾病患者中,我们没有发现不同日期之间DBP的显著差异。在糖尿病肾病和非糖尿病肾病患者中,我们观察到不同的转变对血压的影响是相似的。在周一、周三和周五的亚组中,长的分析间期也与BP有关;而在星期二、星期四和星期六的亚组中,与血压相关的是不同的班次,而不是长的透析间期。结论:长的透析间隔和不同的血液透析班次对血液透析患者的透析前血压有显著影响。在解释血液透析患者的血压时,不同的时间点是一个混杂因素。

期刊介绍: Blood Pressure Monitoring is devoted to original research in blood pressure measurement and blood pressure variability. It includes device technology, analytical methodology of blood pressure over time and its variability, clinical trials - including, but not limited to, pharmacology - involving blood pressure monitoring, blood pressure reactivity, patient evaluation, and outcomes and effectiveness research. This innovative journal contains papers dealing with all aspects of manual, automated, and ambulatory monitoring. Basic and clinical science papers are considered although the emphasis is on clinical medicine. Submitted articles undergo a preliminary review by the editor. Some articles may be returned to authors without further consideration. Those being considered for publication will undergo further assessment and peer-review by the editors and those invited to do so from a reviewer pool.
