The Huawei D smartwatch demonstrated moderate concordance (ICC 0.63) for measuring blood pressure in hypertensive patients, but lacked reliability in normotensive individuals.
Does the Huawei Watch D smartwatch provide reliable blood pressure measurements compared to a validated upper-arm oscillometric device in normotensive and hypertensive patients?
The Huawei Watch D smartwatch provides relatively reliable blood pressure estimates in hypertensive patients but systematically underestimates systolic blood pressure and lacks reliability in normotensive individuals, suggesting it should not replace clinical measurements.
Absolute Event Rate: 0% vs 0%
Abstract Popular wearable devices that record a variety of health metrics, such as real‐time blood pressure (BP), could play a role in detecting hypertension in the population. The objective of this study was to compare the validity of the Huawei D device with that of the Omron M3 Intellisense device used by health workers. Sampling was used to obtain patients with normal and abnormal BP. Measurements were taken on the wrist via the Huawei Watch D, while measurements were made using the Omron M3 Intellisense (prevalidated) device used by experienced healthcare personnel at the health centre. A total of 100 normotensive and 100 hypertensive patients were analysed. The concordance statistics were calculated, and linear regression analysis was performed. The intraclass correlation coefficient was calculated to assess the concordance between the instruments used in the measurement and among the observers who made the measurements under a two‐factor mixed‐effects model, with calculation of the degree of absolute concordance in mean measurements. We found moderate results (systolic blood pressure (SBP) at 30 and 60 min and heart rate at 30 min) and nil for the rest 0.63 (0.36–0.78) < 0.001; in addition, the comparison of the two groups was verified by a Bland–Altamn graph, in which the disparity of the results was observed. The Huawei D BP measuring device was shown to be relatively effective for measuring BP in hypertensive patients. However, the specificity of BP measurement in normotensive patients was not as reliable as in hypertensive patients.
