Abstract
Out-patient-clinic blood pressure (OPC-BP) was compared to blood pressure taken at home (Home-BP) measured three times daily during a two week period in 66 consecutively referred hypertensive subjects. A semi-automatic manometer was used (TM-101) which included a microphone for detection of Korotkoff sounds, self-deflation of cuff pressure and digital display of blood pressure. Mean difference between OPC-BP and Home-BP was systolic +14 mmHg (range -20/+100 mmHg) and diastolic +5 mmHg (range -27/+28 mmHg). Although a significant correlation could be demonstrated between Home-BP and OPC-BP, the inter-individual scatter was pronounced. There was no preponderance of patients with hypertensive organ damage among those with high OPC-BP or Home-BP. It is proposed that home readings should be included in the assessment and control of patients with hypertension, especially among badly controlled subjects and those with borderline hypertension.
