Blood pressure biofeedback treatment of white-coat hypertension . OBJECTIVE The objective of the study was to compare blood pressure ( BP ) biofeedback treatment ( BF ) effects between white-coat hypertension and essential hypertension . METHODS Fifteen white-coat hypertensive out-patients and 23 essential hypertensive out-patients were randomly assigned to groups A or B . Subjects in group A underwent BF once a week for a total of four sessions . Those in group B visited the clinic only to measure BP and later underwent the same BF . RESULTS In group A , BPs of white-coat hypertensives and essential hypertensives were significantly reduced by 22/11 and 14/8 mmHg , respectively . In group B , they were unchanged during the same period but later suppressed by BF . Under BF , pulse and respiratory rates were significantly higher , and elevation of diastolic BP due to mental stress testing was better suppressed in white-coat hypertensives than in essential hypertensives . CONCLUSION This treatment was effective in both types of hypertension , and pressor response to stress seems to be important in the differentiated BF effect .
