Ambulatory blood pressure monitoring

Predictive value of 24-h ambulatory blood pressure monitoring Average 24-h blood pressure values are more closely related to the target-organ damage of hypertension than are clinic blood pressure readings. Preliminary evidence from longitudinal studies suggests that ambulatory blood pressure is also superior to isolated clinic readings in the prognostic evaluation of hypertensive patients. This is supported by the demonstration that in hypertensive patients with left ventricular hypertrophy, regression of cardiac hypertrophy following treatment was better predicted by the drug-induced reduction in 24-h average blood pressure than clinic blood pressure. Blood pressure variability Also, 24-h blood pressure variability seems to be involved in the genesis of hypertension target-organ damage, while the clinical value of specific components of the 24-h blood pressure profile, such the nocturnal blood pressure fall, is still a matter of debate. Similar caution is needed in approaching the clinical significance of white coat hypertension, the definition of which is still affected by important methodological problems
