The aim of the present study was to compare the aortic systolic blood pressure (aSBP), heart-rate-adjusted augmentation index (AIx), and pulse wave velocity (PWV) obtained using the Mobil-O-Graph (IEM, Stolberg, Germany) and SphygmoCor (AtCor, Sydney, Australia) devices in patients receiving peritoneal dialysis (PD).After a 10-minute rest in the supine position, the Mobil-O-Graph and SphygmoCor devices were applied in randomized order in 27 consecutive PD patients. The agreement between the measurements produced by the Mobil-O-Graph and SphygmoCor devices was explored using Bland-Altman analysis.The Mobil-O-Graph-derived aSBP, AIx, and PWV did not differ from the same measurements obtained with SphygmoCor (aSBP: 120.5 ± 18.2 mmHg vs. 124.4 ± 19.0 mmHg, p = 0.438; AIx: 27.0% ± 12.4% vs. 24.5% ± 10.6%, p = 0.428; PWV: 9.5 ± 2.1 m/s vs. 10.1 ± 3.1 m/s, p = 0.397). The slight difference in the estimation of aSBP is possibly explained by the difference in brachial SBP used for the calibration of the devices (131.0 ± 20.6 mmHg vs. 134.5 ± 19.7 mmHg, p = 0.525). Mobil-O-Graph-derived measurements correlated strongly with paired measurements obtained with the SphygmoCor device. Bland-Altman plots showed no evidence of asymmetry and a wide range of agreement between the two devices.Our study shows acceptable agreement between Mobil-O-Graph and SphygmoCor in the estimation of arterial stiffness indices in PD patients. Accordingly, the Mobil-O-Graph device accurately performs aortic ambulatory blood pressure monitoring in this population.
本研究的目的是比较使用Mobil-O-Graph（德国斯托尔伯格IEM公司）和SphygmoCor（澳大利亚悉尼AtCor公司）设备，在接受腹膜透析（PD）的患者中所测得的主动脉收缩压（aSBP）、心率校正的增强指数（AIx）和脉搏波速度（PWV）。在27例连续的PD患者中，仰卧位休息10分钟后，随机顺序应用Mobil-O-Graph和SphygmoCor设备。使用Bland-Altman分析探讨Mobil-O-Graph和SphygmoCor设备所测值之间的一致性。Mobil-O-Graph所测得的aSBP、AIx和PWV与SphygmoCor测得的相同指标无差异（aSBP：120.5±18.2 mmHg对124.4±19.0 mmHg，p = 0.438；AIx：27.0%±12.4%对24.5%±10.6%，p = 0.428；PWV：9.5±2.1 m/s对10.1±3.1 m/s，p = 0.397）。aSBP估计值的微小差异可能是由于用于设备校准的肱动脉收缩压不同所致（131.0±20.6 mmHg对134.5±l9.7 mmHg，p = 0.525）。Mobil-O-Graph测得的值与SphygmoCor设备测得的配对值高度相关。Bland-Altman图显示无不对称证据，且两种设备之间的一致性范围较宽。我们的研究表明，在估计PD患者的动脉僵硬度指标方面，Mobil-O-Graph和SphygmoCor之间具有可接受的一致性。因此，Mobil-O-Graph设备能够准确地对该人群进行主动脉动态血压监测。
