The management of hypertensive disorders of pregnancy (HDP) during hospitalization requires an accurate blood pressure (BP) measurement, mainly by invasive intra-arterial reading. Nevertheless, little is known about the precision of non-invasive (NI) central BP measurements in HDP. We aimed to assess the accuracy of NI central BP assessment in comparison to invasive BP measurement in HDP. This cross-sectional study included all patients with HDP that were admitted to university hospitals for high BP control, from December 2018 till December 2019, and 10 healthy matched non-hypertensive controls. Patients were compared for demographic, anthropometric, and echocardiographic data. In all subjects, invasive BP assessment was done by radial arterial cannulation and NI assessment of BP was performed by an oscillometric automated device (Mobil-O-Graph); the comparison was done after initial control of BP. One hundred patients were included and divided into 3 groups (pre-existing hypertension (HTN), gestational HTN, and pre-eclampsia). There was no statistically significant difference between NI central and invasive methods in measuring both systolic BP (SBP) (126.39 ± 14.5 vs 127.43 ± 15.3, p = 0.5) and diastolic BP (82.41 ± 9.0 vs 83.78 ± 8.9, p = 0.14) among the total studied population. A strong positive correlation was found between NI central and invasive SBP (r = 0.96, p < 0.001). HDP was associated with an increase in arterial stiffness, left ventricular diastolic dysfunction, and complications. Non-invasive measurement of BP using oscillometric automated devices is as accurate as the invasive method, and it is a practical safe method in pregnant women with hypertensive disorders (CTR no. = NCT04303871).

妊娠高血压疾病有创和无创血压评估的比较

住院期间妊娠高血压疾病（HDP）的管理需要准确的血压（BP）测量，主要是通过侵入性动脉内读数进行。尽管如此，人们对HDP中非侵入性（NI）中心BP测量的准确性知之甚少。我们旨在评估与HDP中的侵入性BP测量相比，NI中心BP评估的准确性。这项横断面研究纳入了2018年12月至2019年12月入院医院以进行高BP控制的所有HDP患者，以及10名健康匹配的非高血压对照。比较了患者的人口统计学，人体测量学和超声心动图数据。在所有受试者中，通过radial动脉插管进行侵入性BP评估，通过示波自动装置（Mobil-O-Graph）进行BP的NI评估。最初控制BP后进行比较。包括一百名患者，分为三组（既往高血压（HTN），妊娠HTN和先兆子痫）。在测量收缩压（SBP）（126.39±14.5 vs 127.43±15.3，p = 0.5）和舒张压（82.41±9.0 vs 83.78±8.9，p = 0.14）之间，NI中枢和侵入性方法之间无统计学差异。研究的总人口。在NI中枢性和有创性SBP之间发现强烈的正相关（r = 0.96，p <0.001）。HDP与动脉僵硬度增加，左心室舒张功能障碍和并发症相关。使用示波法自动化设备对BP进行非侵入式测量与进行侵入式方法一样准确，
