目的：在常规临床实践中，使用自动诊室血压（AOBP）或常规手动诊室血压（MOBP）测量来确定隐蔽性高血压[诊室血压（BP）正常，清醒时动态血压高]的患病率。在随机接受AOBP治疗的收缩期高血压患者中，在中位6个月内连续3次访视，评估了隐性高血压的患病率（n = 140）或在常规初级保健实践中继续常规MOBP（n = 112）。使用自动化BpTRU设备记录AOBP，患者在安静的检查室中单独休息。所有患者进行了24小时动态血压monitoring.Results：隐蔽的高血压的患病率在任何一个三次访问计算仅SBP变化之间的12和17%的AOBP组相比，19和22%的MOBP组。在AOBP和MOBP患者中，7%和12%的患者在前两次访视时均存在隐性高血压，6%和7%的患者在所有三次访视时均存在隐性高血压。基于SBP和DBP的隐性高血压患病率相似，单次访视时AOBP为11-15%，MOBP为19-20%，但使用前两次访视的读数时，AOBP组和MOBP组的隐性高血压患病率分别下降至6%和10%，使用所有三次访视时，AOBP组和MOBP组的隐性高血压患病率分别下降至4%和6%。与MOBP相比，AOBP的隐性高血压患病率较低。如果需要在多次访视时满足患有高血压的标准，则患有高血压的患者数量会减少。
Objectives: To determine the prevalence of masked hypertension [normal office blood pressure (BP) with high awake ambulatory BP] using automated office BP (AOBP) or conventional manual office BP (MOBP) measurement in routine clinical practice.Methods: The prevalence of masked hypertension was evaluated on three consecutive visits during a median 6 months period in patients with systolic hypertension randomized to management with AOBP (n = 140) or continued conventional MOBP (n = 112) in routine primary care practice. AOBP was recorded using the automated BpTRU device with the patient resting alone in a quiet examining room. All patients underwent 24-h ambulatory BP monitoring.Results: The prevalence of masked hypertension on any one of three visits calculated using only SBP varied between 12 and 17% in the AOBP group compared with 19 and 22% in the MOBP group. Masked hypertension was present on both of the first two visits in 7 and 12% and on all three visits in 6 and 7% of AOBP and MOBP patients, respectively. The prevalence for masked hypertension based upon both SBP and DBP was similar being 11-15% for AOBP and 19-20% for MOBP patients on single visits, but decreased to 6 and 10% when readings from the first two visits were used and to 4 and 6% when all three visits were used for the AOBP and MOBP groups, respectively.Conclusion: The prevalence of masked hypertension is lower with AOBP compared with MOBP. The number of patients with masked hypertension decreases if the criteria for having this condition need to be met on multiple visits.
