Home blood pressure monitoring. Current knowledge and directions for future research.
Home blood pressure (BP) monitoring has become popular in clinical practice and several automated devices for home BP measurement are now recommendable. Home BP is generally lower than clinic BP, and similar to daytime ambulatory BP. Home BP measurement eliminates the white coat effect and provides a high number of readings, and it is considered more accurate and reproducible than clinic BP. It can improve the sensitivity and statistical power of clinical drug trials and may have a higher prognostic value than clinic BP. Home monitoring may improve compliance and BP control, and reduce costs of hypertension management. Diagnostic thresholds and treatment target values for home BP remain to be established by longitudinal studies. Until then, home BP monitoring is to be considered a supplement. However, high home BP may support or confirm the diagnosis made in the doctor's office, and low home BP may warrant ambulatory BP monitoring. During long-term follow-up, home BP monitoring provides an opportunity for close attention to BP levels and variations. The first international guidelines have established a consensus document with recommendations, including a proposal of preliminary diagnostic thresholds, but further research is needed to define the precise role of home BP monitoring in clinical practice.
