| Abstract
| - One hundred and two healthy elderly volunteers (aged 65-83 years) underwent 24-hour ambulatory blood pressure monitoring. Mean day- and night-time pressures were higher than reported for younger subjects. Removing outlying BP measurements from individual 24-hour recordings only minimally affected mean figures of the group but in some individuals mean day diastolic BP may be up to 5 mmHg lower on editing. Using unedited data, mean day and night pressures were 134/81 mmHg and 119/67 mmHg respectively (corresponding 95th centiles 160/96 mmHg and 146/84 mmHg) and systolic and diastolic BP loads were 36% and 21%. These values may be used as temporary reference values for elderly subjects pending the results of longitudinal studies. Studies quoting ABPM data should specify whether data editing has been employed and, if so, the editing thresholds should be stated.
