ABSTRACT

Background:

Blood pressure (BP) is an important marker for cardiovascular health. However, individual participant’s BP data obtained simultaneously from different sources are not usually available.

Objective:

This paper describes BP data obtained using three various sources, including an ambulatory, a wearable, and home BP devices.

Methods:

In this study, BP was recorded during recruitment using a standardised digital BP device and simultaneously over 24-hours using wearable and ambulatory device. In addition, BP was measured over 7-days using wearable and a home device. Wearable BP data were extracted from the device, and 24-hours ambulatory BP data was downloaded from the device to a computer. Home BP was taken three times per day, including morning, afternoon, evening, at regular times convenient to participants for seven days and recorded into a BP sheet.

Results:

A total of 9090 BP measurements were gathered from 20 healthy volunteers (mean age 20.3±5.4 years, N=10 females). The mean±SD systolic BP and diastolic BP measured at enrollment was 112.35±9.79 mmHg and 73.75±9.14 mmHg. The 24-hours mean±SD systolic BP and diastolic BP measured using the wearable device was 125 ± 5 mmHg and 77 ± 9 mmHg and the ambulatory device was 126 ± 10 mmHg and 75 ± 6 mmHg. The 7 days mean±SD systolic BP and diastolic BP measured using the wearable device was 125 ± 4 mmHg and 77 ± 3 mmHg and using the home device was 112 ± 10 mmHg and 71 ± 8 mmHg.

Conclusions:

The presented datasets serve as the basis for further studies where our data can be combined reasonably with similar studies to understand individual BP differences using different devices. Besides, the BP data acquired noninvasively from a wearable, ambulatory and home device integrated with similar data from other studies might help to determine the utility of wearable BP devices in different groups of people.
