Twenty four hour ambulatory blood pressure monitoring: a new tool for determining cardiovascular prognosis.

Twenty four hour ambulatory blood pressure monitoring (24-H ABPM) plays an important part in the management of subjects with suspected and confirmed disorders of blood pressure regulation. This article reviews the prognostic significance of various aspects of the 24-H ABPM and describes the authors experience in Chesterfield. Over the course of 12 month period from 1 August 2002, 1264 subjects had 24-ABPM. A total of 1187 (93.91%) subjects were included in this study, with mean age of 59.30 years and male:female ratio was 46%: 54 %. Fifty two (4.38%) of the subjects had all of the seven features associated with an adverse prognosis. Only 82 (6.90%) subjects had none of the seven adverse prognostic features with the remainder having one or more adverse prognostic features.
