OBJECTIVE: To evaluate the accuracy of a novel wrist-worn cuff-calibrated photoplethysmography (PPG)-based remote patient monitoring device as an alternative to ambulatory blood pressure monitoring (ABPM).
METHODS: This prospective single-center study included 40 adult patients undergoing standard 24 h ABPM with a 30-min measurement interval. Participants were equipped with a wrist-worn PPG device (CardioWatch 287-2; Corsano Health B.V., The Hague, The Netherlands, manufactured by MMT, Geneva, Switzerland) throughout the ABPM period. Investigational and reference measurements were compared using the average difference and SD for the full 24-h period as well as for awake and asleep periods, individually. Differences in awake-asleep blood pressure (BP) change between the investigational and reference devices were evaluated for all patients and per night-time BP dipper category. Finally, investigational BP monitoring accuracy under motion was visualized.
RESULTS: Throughout the 24-h period, the absolute difference in average SBP and DBP was 3.65 (SD ± 4.57) and 2.98 (SD ± 3.91), respectively. Similar results were obtained for the subsets of day- and night-time determinations. The absolute difference in average awake-asleep BP change was 2.36 (SD ± 2.40) for SBP and 2.17 (SD ± 2.13) for DBP. Comparable absolute differences were present within each of the night-time dipper categories. The performance of the investigational device remained stable under motion.
CONCLUSION: This study presents initial evidence supporting the accuracy of the evaluated wrist-worn PPG-based device in measuring 24-h as well as day- and night-time BP. In all cases, the average difference and SD remained below the cutoff values described by recent European Society of Hypertension guidelines. Therefore, the presented method can provide an accurate alternative to ABPM.
