Abstract
Background: Guidelines recommend ambulatory or home blood pressure monitoring to improve hypertension diagnosis and monitoring. Both these methods are ascribed the same threshold values, but whether they produce similar results has not been established in certain patient groups. Methods: Adults with mild/moderate stroke or transient ischemic attack (N = 80) completed 2 sets of ambulatory and home blood pressure monitoring. Systolic and diastolic blood pressure values from contemporaneous measurements were compared, and the limits of agreement were assessed. Exploratory analyses for predictive factors of any difference were conducted. Results: Daytime ambulatory blood pressure values were consistently lower than home values, the mean difference in systolic blood pressure for initial ambulatory versus first home monitoring was −6.6 ± 13.5 mm Hg (P≤.001), and final ambulatory versus second home monitoring was −7.1 ± 11.0mm Hg (P≤.001). Mean diastolic blood pressure differences were −2.1 ± 8.5mm Hg (P=.03) and −2.0 ± 7.2mm Hg (P=.02). Limits of agreement for systolic blood pressure were −33.0 to 19.9mm Hg and −28.7 to 14.5mm Hg for the 2 comparisons and for DBP were −18.8 to 14.5mm Hg and −16.1 to 12.2mm Hg, respectively. The individual mean change in systolic blood pressure difference was 11.0 ± 8.3mm Hg across the 2 comparisons. No predictive factors for these differences were identified. Conclusions: Daytime ambulatory systolic and diastolic blood pressure values were significantly lower than home monitored values at both time points. Differences between the 2 methods were not reproducible for individuals. Using the same threshold value for both out-of-office measurement methods may not be appropriate in patients with cerebrovascular disease.
