title: Role of Ambulatory Blood Pressure Measurement in Diagnosis and Control of Hypertension.
abstract: Office blood pressure (BP) measurements by sphygmomanometer are not necessarily representative of patient's usual blood pressure. In contrast, ambulatory blood pressure measurements (ABPM) represent a large number of readings and may reflect the actual BP status of an individual. In this study, 150 individuals were studied in 2 groups. 110 patients (group A) had stage I & II, hypertension based on casual BP readings. 26 (23.6%) of them were found to be normontensive as per existing ABPM standard. There were 40 patients with poorly controlled hypertension on multiple drugs (group B). The trough/peak ratio of > 50% was seen in 12.5% of these patients at start of study. This increased to 84.8% after modification of drugs as per the profile on ABPM, thus indicating usefulness in achieving a smoother control.
