Real World Home Blood Pressure Variability in Over 56,000 Individuals With Nearly 17 Million Measurements

Abstract: Using the largest BP data set we are aware of, with the benefits and limitations of real-world measurement, we could show the pattern of BPV and provide reference values that may be helpful in understanding the nature of BPV as self-measurement at home becomes more common, and help guide individualized management.

“… 1 Rather than representing random phenomena, those changes are the result of interactions between environmental and behavioral factors and the cardiovascular regulation system. 2 These give rise to long-term (clinic or visit-to-visit) variability, 3 mid-term (day-to-day) variability, usually assessed by home monitoring, 3 or short-term variability, known as circadian BP variation and assessed by 24-hour ambulatory monitoring. 4 These fluctuations have prognostic importance.…”

“…Variability in blood pressure is predictive of future cardiovascular disease and morbidity, but has been challenging to characterize with traditional studies, particularly in real-world settings (as opposed to clinical settings which can influence vital signs). Kim et al 15 analyzed blood pressure readings from over 50,000 individuals (with 17 million measurements) using a wireless blood pressure monitor. They characterized blood pressure variability and how it changes with season of the year, day of the week, and time of day, for example, showing that variability is higher during weekdays, particularly for females.…”

“…Analyzing data from consumer users of apps and wearables has allowed researchers to characterize health indicators, such as blood pressure variability, 15 and points to promising new avenues of research, such as focusing physical activity interventions on the activity poor segment of a population. 11 We also see that external factors, such as the walkability of a city 11 and social pressures preventing sleep, 13 can have a strong influence on health behaviors.…”

“…These risk factors are most commonly assessed via measurement at a single time point, with the result guiding clinical action (e.g., prescription for a cholesterol-lowering statin drug) [189]. However, many risk factors vary substantially and rhythmically over the course of hours and days [101112], suggesting that a single point measure may be more reliably interpreted when taken in temporal context. Indeed, accounting for short-timescale variability has improved the ability to anticipate cardiovascular events.…”
