Key result
The average nighttime systolic blood pressure measured by a wrist-type home monitoring device showed good reproducibility between two consecutive nights with a non-significant difference of 1.6 mmHg.
Why the study?
The study was conducted to investigate the reproducibility of nighttime home BP measured by a wrist-type nocturnal home BP monitoring device.
Is nighttime home blood pressure measured by a wrist-type nocturnal device reproducible across consecutive nights in hypertensive patients?
Observational (n=46)
No
Is nighttime home blood pressure measured by a wrist-type nocturnal device reproducible across consecutive nights in hypertensive patients?
Effect estimate: Difference 1.6 mmHg
Absolute Event Rate: 117% vs 115.4%
p-value: p=0.124
Wrist-type nocturnal home blood pressure monitors provide reliable average systolic blood pressure readings even on the first night, though multiple nights may be needed to accurately assess blood pressure variability.

Supports single-night wrist-device averages for SBP in hypertensives; leaves open optimal multi-night protocols for variability assessment.
Tomitani et al. (2021) conducted an observational in Hypertension (n=46). Wrist-type nocturnal home blood pressure monitoring device (HEM-9601T) vs. Second night measurement (reproducibility comparison) was evaluated on Difference in average nighttime systolic blood pressure between the first and second night measured by wrist-device (Difference 1.6 mmHg, p=0.124). The average nighttime systolic blood pressure measured by a wrist-type home monitoring device showed good reproducibility between two consecutive nights with a non-significant difference of 1.6 mmHg.
