Conditions
Brief summary
Home blood pressure measurement has been recommended to use in the diagnosis of hypertension. The investigators have developed diagnostic algorithm of hypertension by using 24-hour and home blood pressure measurement. However, the diagnostic agreement between home blood pressure measurement and 24-hour ambulatory blood pressure measurement is about 70 - 85%. The discrepancy of diagnosis between home blood pressure measurement and 24-hour ambulatory blood pressure is one of the barriers to introduce home blood pressure measurement in the diagnosis of hypertension. To solve the discrepancy, identifying the characteristic patients showing discrepancy of hypertension diagnosis between home blood pressure measurement and 24-hour ambulatory blood pressure measurement is needed. The purpose of the present study are (1) to validate the diagnostic algorithm of hypertension by using 24-hour ambulatory blood pressure and home blood pressure measurement the investigators have developed, and (2) to identifying the characteristics of patients showing discrepancy of diagnosis between 24-hour ambulatory blood pressure and home blood pressure measurement, and (3) lastly to improve the diagnostic algorithm of hypertension by using home blood pressure measurement.
