Home Blood Pressure Monitoring: Primary Role in Hypertension Management

In the last two decades, considerable evidence on home blood pressure monitoring has accumulated and current guidelines recommend its wide application in clinical practice. First, several outcome studies have shown that the ability of home blood pressure measurements in predicting preclinical target organ damage and cardiovascular events is superior to that of the conventional office blood pressure measurements and similar to that of 24-hour ambulatory monitoring. Second, cross-sectional studies showed considerable agreement of home blood pressure measurements with ambulatory monitoring in detecting the white-coat and masked hypertension phenomena, in both untreated and treated subjects. Third, studies have shown larger blood pressure decline by using home blood pressure monitoring instead of office measurements for treatment adjustment. Fourth, in treated hypertensives, home blood pressure monitoring has been shown to improve long-term adherence to antihypertensive drug treatment and thus, has improved hypertension control rates. These data suggest that home blood pressure should no longer be regarded as only a screening tool that requires confirmation by ambulatory monitoring. Provided that an unbiased assessment is obtained according to current recommendations, home blood pressure monitoring should have primary role in diagnosis, treatment adjustment, and long-term follow-up of most cases with hypertension.
