Validation of a popular consumer-grade cuffless blood pressure device for continuous 24 h monitoring.

ABSTRACT:

Aims

Hypertension is a leading cause of death worldwide, yet many hypertensive cases remain undiagnosed. Wearable, cuffless blood pressure (BP) monitors could be deployed at scale, but their accuracy remains undetermined.

Methods and results

This study validated a popular consumer-grade wearable BP monitor (W-BPM, Aktiia), using a medical-grade ambulatory device (A-BPM, Mobil-O-Graph), for reference. Thirty-one participants (aged 19-62 years, 17 (55%) females, in office BP 121 ± 15 over 77 ± 12 mmHg) simultaneously wore both devices for 24 h. Systolic BP (SBP), diastolic BP (DBP), and heart rate (HR) were measured in pre-set intervals by the A-BPM and at rest by the W-BPM. Agreement was assessed using standard methods. Accuracy in identifying high BP (mean 24 h SBP/DBP > 130
