Comparison of different schedules of nocturnal home blood pressure measurement using an information/communication technology‐based device in hypertensive patients

Abstract

Nocturnal blood pressure (BP) measured by ambulatory BP monitoring (ABPM) is a better predictor of future cardiovascular events than daytime BP in hypertensive patients. [1][2][3] In recent years, nocturnal BP measured by home BP monitoring (HBPM) has become available for clinical practice, and a recent meta-analysis showed that the clinical significance of nocturnal BP measured by HBPM is comparable to that of nocturnal BP measured by ABPM. 4 Owing to its simplicity, convenience, and tolerability, HBPM has been rapidly adopted by many clinics and is now recommended by numerous hypertension guidelines. 5-10 The potential advantages of nocturnal HBPM as a substitute for nocturnal ABPM are that it permits the collection of nocturnal home BP values over multiple nights, in the manner of conventional home BP measurement, which can be measured in the morning and evening. On the other hand, participants are likely to measure nocturnal BP levels depending on their own lifestyle. Recently developed HBPM devices permit participants to set specific lengths of time after their chosen bedtime for the measurement of nocturnal Additional supporting information may be found online in the Supporting Information section at the end of the article.

Nighttime Blood Pressure Measured by Home Blood Pressure Monitoring as an Independent Predictor of Cardiovascular Events in General Practice

“…7 In our recent crossover study using a validated automatic information/communication technology–based nighttime HBPM device, the reliability and levels of nighttime HBP were similar between nighttime HBP measured at fixed time points (2:00, 3:00, and 4:00 am ) and that measured based on the chosen bedtime of individual subjects (measurement at 2, 3, and 4 hours after the chosen bedtime). 28 Nighttime HSBP at 2:00 am and that at 3:00 am were almost the same but that at 4:00 am was slightly higher (Table 1). In the present study, nighttime HSBP at 2:00 to 3:00 am remained significantly associated with cardiovascular and stroke risk independently of both office SBP and morning HSBP.…”

Clinical significance of nocturnal home blood pressure monitoring and nocturnal hypertension in Asia

“…Although recently developed HBPM devices permit participants to set the nocturnal BP measurement schedule freely, there are no established criteria regarding when and at what time intervals the nocturnal BP measurements should be taken in one night. We previously compared the reliability of different schedules of multiple nocturnal home BP readings measured based on the participants’ specified bedtimes and those measured at fixed time points 17 . The reliability of the nocturnal home BP values measured using bedtime‐based measurements and that of the values measured using fixed‐time measurements were similar.…”

Home Blood Pressure Monitoring: Current Status and New Developments

“…27 The reliability of nocturnal HBPM appeared to be similar when HBPM was performed at intervals based on bedtime (e.g., 2, 3, or 4 hours after a chosen bedtime) or when fixed times were chosen (e.g., 2 am , 3 am , and 4 am ). 28 …”
