Home blood pressure measurements correlated more strongly with 24-hour ambulatory diastolic blood pressure than office measurements (r=0.76 vs 0.36).
Observational (n=93)
Does home blood pressure measurement reflect 24-hour ambulatory blood pressure more accurately than office blood pressure measurement in patients with mild untreated hypertension?
Home blood pressure readings reflect the overall 24-hour blood pressure level more reliably than office readings in patients with mild untreated hypertension, particularly for diastolic blood pressure.
Absolute Event Rate: 0.76% vs 0.36%
To investigate the value of home blood pressure (BP) measurements, the BP was recorded daily by the patient at home and compared with recordings in the physician's office and with a 24-hour BP recording taken with a noninvasive ambulatory BP recorder in a group of 93 patients with mild untreated hypertension. Office BPs (mean 148/94 mm Hg) were higher than either home (138/89 mm Hg) or average 24-hour BPs (131/89 mm Hg). For systolic BP, home and office measurements gave similar correlations with 24-hour BP (0.67 and 0.55). For diastolic BP, however, home readings were lower and more accurate (0.76 vs 0.36). Thus, our findings indicate that home readings reflect the overall level of BP more reliably than office readings, and if due consideration is given to the fact that they are usually lower than office readings, they may be used as an alternative and cost-effective means of evaluating patients with mild hypertension.
Kleinert et al. (1984) conducted an observational in mild untreated hypertension (n=93). Home blood pressure measurement vs. Office blood pressure measurement was evaluated on Correlation with 24-hour ambulatory diastolic blood pressure. Home blood pressure measurements correlated more strongly with 24-hour ambulatory diastolic blood pressure than office measurements (r=0.76 vs 0.36).
