In hemodialysis patients, blood pressure (BP) measured at the postdialysis period (POSBP) can be used to diagnose hypertension. However, the optimal time point for POSBP remains uncertain. This cross-sectional study evaluated 210 long-term dialysis patients (66.7% men; age = 56.9 ± 15.7 years), who underwent POSBP measurements at three time points [immediately after dialysis period ended (POSBP1); after blood return (POSBP2) and after fistula hemostasis or catheter sealing (POSBP3)] and home BP monitoring (HBPM) over one week. POSBP1, POSBP2, POSBP3 and HBPM values were 139.1 ± 22.4/73.2 ± 12.5, 142.8 ± 22.8/74.3 ± 12.3, 142.8 ± 21.8/74.0 ± 12.2 and 131.2 ± 21.2/77.9 ± 12.1 mmHg, respectively. Systolic POSBP3 and POSBP2 were significantly greater (p < 0.05) than systolic POSBP1. POSBP3 had the greatest correlation with HBPM, while elevated (>130/80 mmHg) POSBP3 showed the highest numerical accuracy (AUC [95% CI] = 0.696 [0.638-0.754]) and concordance (kappa coefficient = 0.41) with elevated HBPM (≥130/80 mmHg) compared with POSBP1 and POSBP2. These findings suggest that POSBP3 may be a preferable measurement for assessment of POSBP in hemodialysis patients.
在血液透析患者中,透析后阶段(POSBP)测量的血压(BP)可用于诊断高血压。然而,POSBP的最佳时间点仍不确定。这项横断面研究评估了210名长期透析患者(男性占66.7%;年龄=56.9±15.7岁),这些患者在三个时间点进行了POSBP测量[透析阶段结束后立即测量(POSBP1);回血后测量(POSBP2)以及内瘘止血或导管封堵后测量(POSBP3)],并进行了为期一周的家庭血压监测(HBPM)。POSBP1、POSBP2、POSBP3和HBPM的值分别为139.1±22.4/73.2±12.5、142.8±22.8/74.3±12.3、142.8±21.8/74.0±12.2和131.2±21.2/77.9±12.1mmHg。收缩压POSBP3和POSBP2显著高于收缩压POSBP1(p<0.05)。POSBP3与HBPM的相关性最强,与POSBP1和POSBP2相比,升高(>130/80mmHg)的POSBP3在数值准确性(AUC[95%CI]=0.696[0.638 - 0.754])和与升高的HBPM(≥130/80mmHg)的一致性(kappa系数=0.41)方面表现最高。这些发现表明,POSBP3可能是评估血液透析患者POSBP的更优测量方法。
