Summary

This study tested whether an automatic blood pressure machine (WatchBP Office) gives more accurate readings than the traditional manual method in 149 Chinese adults with high blood pressure. The automatic machine takes several readings and averages them, which may reduce the 'white-coat effect' (nervousness that raises blood pressure in the doctor's office). Results were compared to a 48-hour ambulatory blood pressure monitor, the current gold standard.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * diagnosis of essential hypertension Exclusion Criteria: * (i) severe hypertension as defined by clinical systolic BP ≥180 mmHg and/or diastolic BP ≥110 mmHg (because they may need emergency treatment and it is unethical to delay such treatment due to the proposed project), (ii) inability to provide consent, (iii) pregnancy, (iv) night-time occupations (we need to compare AOBP and clinic BP readings to daytime ABPM average when the patient should be awake), (v) are occupational drivers (because potential dangers in driving could occur when patients are asked to remain still), (vi) receiving anti-coagulants (to prevent bruises when using ABPM), (vii) with known atrial fibrillation (as ABPMs and AOBP use have not been validated in this group)
