Associations between visit-to-visit variability in blood pressure measured in the office and antihypertensive drugs: the J-HOME-Morning study.

Abstract

The factors associated with visit-to-visit variability in blood pressure (BP) measured in the office between the two visits were identified in 1379 treated hypertensive patients (mean age, 66.1 ± 11.0 y; women, 53.8%). Multivariate regression analysis showed that office BP and visit-to-visit heart rate variability were positively associated with visit-to-visit BP variability, whereas body mass index, duration of antihypertensive medication, and taking amlodipine were negatively associated with visit-to-visit BP variability. Further prospective studies are required to clarify the causal relationships between these factors and visit-to-visit BP variability among treated hypertensive patients.
