Abstract

Purpose: Twenty-four hours of ambulatory blood pressure monitoring (ABPM) is recommended in several guidelines as the best method for diagnosing hypertension. In general, the prognostic value of ABPM is superior to single office blood pressure (BP) measurements. Unfortunately, some patients experience considerable discomfort during frequently repeated forceful cuff inflations.

Materials and methods: In this study we investigated the difference in mean daytime systolic BP (SBP) between low-frequency ABPM (LF-ABPM), measuring once every hour, and high-frequency ABPM (HF-ABPM), measuring three times an hour during daytime, and two times an hour during night-time.

Results: Seventy-one patients were included in the analysis. All included patients had an HF-ABPM performed first and within a few weeks they underwent an LF-ABPM. The average day time difference in SBP between the two frequencies was 3.8 mmHg (p-value = 0.07) for mild, 8.2 mmHg (p-value < 0.01) for moderate and 15 mmHg (p-value < 0.001) for severe hypertension. A similar pattern was seen for night-time SBP. This study suggests that mean BP is similar between the two measuring frequencies for normotensive and mild hypertensive patients, while HF-ABPM results in a higher 24-h mean BP for moderate- and severe hypertensive patients.

Conclusion: LF-ABPM may more correctly reflect the resting blood pressure in patients with moderate and severe hypertension.

动态血压使用60分钟而不是20分钟间隔可以更好地反映静息血压。

目的:24小时动态血压监测(ABPM)在一些指南中被推荐为诊断高血压的最佳方法。一般来说，ABPM的预后价值优于单一办公室血压(BP)测量。不幸的是，一些患者在频繁重复的强力袖带充气过程中会感到相当不适。材料和方法:在本研究中，我们研究了低频ABPM (LF-ABPM)(每小时测量一次)和高频ABPM (HF-ABPM)(白天每小时测量3次，夜间每小时测量2次)在白天平均收缩压(SBP)的差异。结果:71例患者纳入分析。所有纳入的患者首先进行HF-ABPM，并在几周内进行LF-ABPM。两种频率的平均收缩压日差轻度为3.8 mmHg (p值= 0.07)，中度为8.2 mmHg (p值< 0.01)，重度高血压为15 mmHg (p值< 0.001)。夜间收缩压也出现了类似的模式。本研究提示，正常和轻度高血压患者的平均血压在两种测量频率之间相似，而HF-ABPM导致中度和重度高血压患者的24小时平均血压更高。结论:LF-ABPM能更准确地反映中重度高血压患者的静息血压。
