Office and ambulatory blood pressure control in treated hypertension

We examined the prognostic value of 24-hour blood pressure control in 790 hypertensive subjects who underwent blood pressure monitoring before and after an average follow-up of 3.7 years. At the follow-up visit, 26.6% showed adequate blood pressure control using office values, and 37.3% showed adequate control using ambulatory values. Ambulatory blood pressure control predicted less risk for cardiovascular disease even after adjustmentfor other risk factors. We conclude that ambulatory blood pressure control is superior to office control for cardiovascular risk stratification in treated hypertensive subjects.
