Office blood pressure (OBP) measurement is the most common method of blood pressure measurement. However, it is associated with several pitfalls as white coat effect and masked hypertension. Ambulatory blood pressure monitoring (ABPM) is usually used for diagnosis of hypertension and elimination of white coat effect. This study aimed to assess the correlation and degree of agreement of the automated sequential blood pressure (ASqBP) with OBP and ABPM. Patients presented to hypertension clinic were included. Each patient had his blood pressure recorded by three methods: OBP using a digital sphygmomanometer device, unattended ASqBP using sequential BP devices with recording of the readings over 30 min, and ABPM that was performed within 48 h of office visit using portable BP devices with BP recording over 24 h.
We recruited 64 patients (age 50.0 ± 15.0 years and female gender 53.1%). We found a strong positive correlation between ASqBP and OBP readings (r 0.81 for SBP and 0.83 for DBP, p < 0.001). We also found a strong positive correlation between ASqBP and ABPM readings (r 0.74, p < 0.001). The ASqBP readings were lower than OBP (137.0 ± 16.8/86.4 ± 13.8 vs. 142.7 ± 15.5/88.5 ± 12.3) and close to ABPM readings (average 24 h, 134.0 ± 15.4/88.5 ± 12.3, and daytime, 135.8 ± 15.7/82.1 ± 13.7). For SBP readings, there was moderate agreement between ASqBP and AMBP (both average and daytime). For DBP readings, there was fair agreement between ASqBP and AMBP (both average and daytime).
ASqBP measurement has good correlation with OBP and ABPM readings. Unattended automated office pressure has moderate degree of agreement with ABPM for the SBP& fair degree of agreement for the DBP. It can be used in the hypertension clinics to eliminate the problems of white coat effect and marked BP variability.
诊室血压（OBP）测量是最常用的血压测量方法。然而，它存在一些缺陷，如白大衣效应和隐匿性高血压。动态血压监测（ABPM）通常用于高血压的诊断及消除白大衣效应。本研究旨在评估自动序贯血压（ASqBP）与OBP和ABPM之间的相关性及一致性程度。纳入到高血压门诊就诊的患者。每位患者通过三种方法记录血压：使用数字血压计测量OBP；使用序贯血压装置在30分钟内记录读数的无人值守ASqBP；在门诊就诊48小时内使用便携式血压装置进行24小时血压记录的ABPM。
我们招募了64例患者（年龄50.0±15.0岁，女性占53.1%）。我们发现ASqBP与OBP读数之间存在强正相关（收缩压r为0.81，舒张压r为0.83，p<0.001）。我们还发现ASqBP与ABPM读数之间存在强正相关（r为0.74，p<0.001）。ASqBP读数低于OBP（137.0±16.8/86.4±13.8 vs. 142.7±15.5/88.5±12.3），且接近ABPM读数（24小时平均值，134.0±15.4/88.5±12.3，白天，135.8±15.
7/82.1±13.7）。对于收缩压读数，ASqBP与ABPM（平均值和白天）之间存在中度一致性。对于舒张压读数，ASqBP与ABPM（平均值和白天）之间存在尚可的一致性。
ASqBP测量与OBP和ABPM读数具有良好的相关性。无人值守的自动诊室血压与ABPM在收缩压方面具有中度一致性，在舒张压方面具有尚可的一致性。它可用于高血压门诊，以消除白大衣效应和明显的血压变异性问题。
