Data from 2322 treated patients with hypertension who underwent office BP measurement, then 24-hour ambulatory BP monitoring, then home BP monitoring for 5 days were analyzed. Corresponding BP thresholds for office, home, and ambulatory measurements were determined using Deming regression. Values equivalent to office systolic BP (SBP) of 120 and 140 mm Hg were as follows: 115.9 and 127.7 mm Hg for 24-hour ambulatory SBP; 120.8 and 134.0 mm Hg for daytime ambulatory SBP; 104.9 and 117.9 mm Hg for nighttime ambulatory SBP; and 122.0 and 134.2 mm Hg for morning-evening average home SBP. Deming regression showed that morning-evening average home SBP and daytime ambulatory SBP were almost the same (home SBP=0.99×daytime ambulatory SBP+0.27 mm Hg; r=0.627). Morning-evening average home SBP values of 120 and 135 mm Hg were equivalent to daytime ambulatory SBP values of 119.1 and 133.9 mm Hg, respectively. A home SBP threshold of 130 mm Hg corresponded to 24-hour and nighttime ambulatory SBP values of 123.5 and 113.6 mm Hg, whereas a home SBP threshold of 135 mm Hg corresponded to 24-hour and nighttime ambulatory SBP values of 128.0 and 119.2 mm Hg.
Ambulatory and home BP thresholds in this analysis were similar to those proposed by existing guidelines. The similarity between the home BP and daytime ambulatory BP thresholds was a clinically relevant finding.
结果:来自2322名接受办公室血压测量的高血压患者的数据,然后24小时动态血压监测,然后对家庭血压监测5天进行分析。办公室的相应BP阈值,home,并使用Deming回归确定动态测量值。相当于120和140mmHg的办公室收缩压BP(SBP)的值如下:24小时动态SBP为115.9和127.7mmHg;白天动态SBP为120.8和134.0mmHg;夜间动态SBP为104.9和117.9mmHg;早晚平均家庭SBP为122.0和134.2mmHg。戴明回归显示,早晚平均家庭SBP和白天动态SBP几乎相同(家庭SBP=0.99×白天动态SBP0.27mmHg;r=0.627)。早晚平均家庭SBP值为120和135mmHg,相当于白天的动态SBP值为119.1和133.9mmHg,分别。家庭SBP阈值为130mmHg,对应于24小时和夜间动态SBP值123.5和113.6mmHg,而135mmHg的家庭SBP阈值对应于24小时和夜间动态SBP值128.0和119.2mmHg。
结论:本分析中的动态和家庭血压阈值与现有指南提出的阈值相似。家庭BP和白天动态BP阈值之间的相似性是临床相关发现。
