title: Are some hypertensive patients overtreated? A prospective study of ambulatory blood pressure recording.
abstract: Ambulatory blood pressure (BP) was recorded in hypertensive patients whose physicians had been asked to reduce diastolic pressure measured in the office to 90 mm Hg or less. 34 hypertensive patients with a diastolic pressure measured by their physician of 95 mm Hg or more despite antihypertensive therapy had their treatment changed with the aim of achieving this pre-set goal within 3 months. At the beginning and the end of the study, ambulatory BP was monitored during the daytime with a portable non-invasive recorder. The results of the ambulatory recordings were not made available to the physicians until completion of the study. In half the patients the ambulatory diastolic pressure was already 90 mm Hg or less at the start. In these patients, treatment adjustment did not further decrease ambulatory BP. In contrast, patients who initially had an ambulatory diastolic pressure above 90 mm Hg had a significantly decreased ambulatory BP at the end of the study. Intensifying the therapy of hypertensive patients who have a normal ambulatory BP may result in overtreatment without any real gain in BP control.
