ABSTRACT

Background:

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

Objective:

This paper describes BP data obtained using 3 different sources including an ambulatory, a wearable, and home BP devices.

Methods:

In this study BP was recorded during recruitment using a standarised digital BP device and simultaneously over 24-hours using wearable and ambulatory device. In addition, BP was measured over 7-days using a 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 7 days and recorded into a BP sheet.

Results:

A total of 9090 BP measurements were gathered from 20 healthy volunteers (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 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 presented data sources can be combined in a reasonable way or used all together comparing BP data, acquired noninvasively from a wearable, ambulatory and home device to understand the future utility.
