Key result
Tonometric ABPM misclassifies ~46% of hypertensive patients compared to standard oscillometric monitoring.
Why the study?
Reliable screening tools for diagnosing arterial hypertension are important for correct cardiovascular risk stratification, prompting evaluation of a wrist-worn tonometric device for 24-hour blood pressure measurement.
Does tonometric 24-hour blood pressure monitoring accurately diagnose hypertension and non-dipping in adults with a history of normal blood pressure compared to oscillometric monitoring?

Does tonometric 24-hour blood pressure monitoring accurately diagnose hypertension and non-dipping in adults with a history of normal blood pressure compared to oscillometric monitoring?
Wrist-worn tonometric 24-hour blood pressure monitoring is insufficiently accurate for hypertension screening due to high rates of misclassification compared to standard oscillometric devices.

Findings caution against tonometric ABPM for screening; leaves open need for prospective device validation in diverse cohorts.
OBJECTIVES: Arterial hypertension increases the risk of developing cardiovascular disease. Reliable screening tools for diagnosing hypertension are important to ensure correct risk stratification of subjects. In this study, we aimed to analyse if a wrist-worn device using a tonometric technique for measuring of 24-hour blood pressure could be used to diagnose hypertension and non-dipping. A conventional device using oscillometric measurements was used as golden standard. Secondary aim was to compare the degree of discomfort related to monitoring with the two devices. METHODS: In 89 subjects with a history of normal blood pressure and naive to ambulatory BP monitoring (ABPM), 24-hour ABPM was measured simultaneously with A&D TM2430 (oscillometric technique) and BPro (tonometric technique). RESULTS: When comparing measurements from the two devices, we found that the tonometric device misclassified 46% of hypertensive subjects and 69% of non-dippers. The tonometric device measured significantly lower systolic 24-hour and daytime blood pressure. The subjects reported less discomfort related to the tonometric than the oscillometric device. CONCLUSION: Despite less discomfort related to usage of the tonometric device for 24-hour blood pressure monitoring compared to an oscillometric device, misclassification of hypertension and non-dipping makes the tonometric device inappropriate as a screening instrument.

Hornstrup et al. (2023) conducted a cross-sectional in Normal blood pressure history (screening for hypertension) (n=89). Tonometric 24-hour blood pressure monitoring (BPro) vs. Oscillometric 24-hour blood pressure monitoring (A&D TM2430) was evaluated on Diagnosis of hypertension (p=0.585). The tonometric device misclassified 46% of hypertensive subjects and 69% of non-dippers compared to the oscillometric gold standard, making it inappropriate as a screening instrument.
