Letter to the Editor Is the use of ABPM justified in patients on 1 or 2 antihypertensive medications

We studied the utility of ABPM in patients with elevated clinic BP on 1–2 antihypertensive medications (group B, N=117), compared with those on no medications (group A, N=76) and on ≥3 medications (group C, N=110). 35% of patients in group B had adequately controlled 24-h BP based on ABPM, compared with 22.4% in group A (P=0.06) and 19.1% in group C (P=0.007). Antihypertensive treatment was not escalated in patients with adequately controlled BP. This suggests that ABPM has an important role in therapeutic decisionmaking for patients on 1–2 antihypertensive medications. © 2007 Elsevier Ireland Ltd. All rights reserved.
