title: Visit-to-Visit Variability of Systolic Blood Pressure and Cardiovascular Disease.
abstract: Visit-to-visit variability of blood pressure (VVV of BP) is gaining interest as a prognostic marker for stroke, cardiovascular disease, and all-cause mortality. In this review, we discuss different metrics used to define VVV of BP, explore the potential sources of this phenomenon including patient characteristics and antihypertensive medication classes, and discuss recent evidence of its relation with cardiovascular outcomes. Current evidence relies on secondary analyses of clinical trials or on observational studies, none of which was designed to examine VVV of BP specifically. More research is required to develop standardized definitions of VVV of BP, to confirm the value of VVV as a prognostic indicator, and to ascertain whether efforts to reduce VVV of BP in addition to mean BP will improve outcomes.
