Automatic vs Traditional Blood Pressure Measurement in Chinese Patients

This study focuses on finding out if a newer method of checking blood pressure called Automatic Office Blood Pressure (AOBP) is more accurate than the traditional way doctors measure blood pressure in their offices. AOBP has been shown to provide accurate readings similar to those obtained from ambulatory blood pressure monitoring (ABPM), which is known as the best method currently available. The study involves 150 Chinese adults who have high blood pressure and are seen at a government-funded clinic. The goal is to see if this new method, specifically using a machine called WatchBP Office, can give better blood pressure results than the traditional office method. This is important because if AOBP is found to be more reliable, it might become a standard practice in clinics, potentially improving how high blood pressure is diagnosed and managed. Participants will undergo three different methods of blood pressure measurement: the gold-standard 48-hour ABPM, the WatchBP Office AOBP, and the traditional office blood pressure measurement, which will be done twice. The study will evaluate how similar the readings from the AOBP and traditional methods are compared to the ABPM readings by analyzing factors like sensitivity and specificity. This means the study will check how good each method is at accurately diagnosing high blood pressure, hidden high blood pressure, or cases where blood pressure is only high when measured by a doctor, known as "white-coat hypertension." The results will help determine if the WatchBP Office machine can be a better option for regular use in clinics, making blood pressure management more accurate and effective.
