Magnitude of Hypotension Based on Office and Ambulatory Blood Pressure Monitoring: Results From a Cohort of 5066 Treated Hypertensive Patients Aged 80Â Years and Older

One in 3 very elderly treated hypertensive patients attended in usual clinical practice were potentially at risk of having hypotension according to daytime ABPM. More than half of them had masked hypotension; that is, they were not identified if relying on office BP alone. Thus, ABPM could be especially helpful for identifying ambulatory hypotension and avoiding overtreatment, in particular, in patients with diabetes, heart disease, or on antihypertensive polytherapy.
