Real-world home blood pressure measurement was non-standardized in about one-third of participants, and blood pressure variability increased significantly with higher blood pressure levels (P<0.001).
Observational (n=5,078)
Yes
Real-world home blood pressure measurement in China often deviates from guideline recommendations, and blood pressure variability is higher in patients with elevated blood pressure.
p-value: p=<0.001
Objective: Home blood pressure (BP) measurement (HBPM) was recommended for regularly evaluating and monitoring the variation of BP in recent guidelines, but the real-world HBPM pattern and BP variability (BPV) is still unclear. This study aims to explore the individual behavior pattern of HBPM and BPV based on a nationwide HBPM dataset in China.Design and method: From Mar. 1st, 2024 to Dec. 31st, 2024, individual HBPM data were collected from Hanvon® HBPM device users at 303 cities in 31 provinces across mainland of China. Individual BP measurement pattern, including time period, frequency, proportion of single or repeated measurements, as well as BP profile were analyzed. BPV was indexed by standard deviation (SD) of systolic/diastolic BP. Results: A total of 5078 HBPM regular users (at least twice measurement during the period) with 597173 valid data were included. 74.2%(3768) of participants were male, mean age 48.8(±13.2) y. 93.2% of participants measured BP after waking-up (6-9 o’clock) and 91.4% before bed (20-24 o’clock). 62.0% of participants measured twice (morning or evening) or more per day. Repeated measurement (twice measurements within 5 minutes) was seen in 61.2% participants, 38.8% only once, and average 2.3(±1.8) times in all the participants. The average systolic BP was 126.6(±11.2) mmHg, diastolic BP 82.7(±9.3) mmHg. The SD of systolic/diastolic BP were 11.15(±3.48)/7.81(±2.52) mmHg, and increased gradually with BP levels, 10.11(±3.10)/7.03(±2.15) mmHg in normotension, 11.17(±3.39)/7.70(±2.35) mmHg in high-normal, and 11.91(±3.73)/8.66(±2.86) mmHg in hypertensive participants (P<0.001, respectively). Conclusions: Real-world HBPM was not well-conformed to the guidelines’ recommendation, non-standardized measurement was demonstrated in about 1/3 participants in China. BPV increased with BP levels, indicating the necessity of standardized HBPM for hypertension management.
Liu et al. (Fri,) conducted a observational in Home blood pressure monitoring (n=5,078). Home blood pressure measurement (HBPM) was evaluated on Individual behavior pattern of HBPM and blood pressure variability (BPV) (p=<0.001). Real-world home blood pressure measurement was non-standardized in about one-third of participants, and blood pressure variability increased significantly with higher blood pressure levels (P<0.001).
