Blood pressure differences between home monitoring and daytime ambulatory values and their reproducibility in treated hypertensive stroke and TIA patients
American Heart Journal Dec 15, 2018
Davison WJ, et al. – In this study, researchers compared value difference in home vs ambulatory blood pressure (BP) monitoring and their reproducibility in treated patients with mild/moderate hypertensive stroke and transient ischemic attack (TIA; n=80). Study participants were asked to complete two sets of ambulatory and home BP monitoring. The investigators compared systolic (SBP) and diastolic BP (DBP) levels from contemporaneous measurements and evaluated the limits of agreement. Remarkably, the noted lower daytime ambulatory SBP and DBP values vs home-monitored values at both time points, with −6.6 ± 13.5 mmHg mean difference in SBP for initial ambulatory vs first home monitoring and −7.1 ± 11.0 mmHg for final ambulatory vs second home monitoring. No reproducibility was observed with regard to the differences between the two methods. For patients with cerebrovascular disease, it may not be appropriate to use the same threshold value for both out-of-office measurement methods.
