Key result
Visit-to-visit systolic blood pressure variability (SD-SBP ≥10 mm Hg) was associated with an increased risk of cardiovascular events or death (HR 1.43; 95% CI 1.25-1.63; P<0.01).

VV-BPV was associated with CV outcomes in this cohort; leaves open whether it adds value beyond mean BP for risk stratification or intervention.

Does high visit-to-visit systolic blood pressure variability increase the risk of cardiovascular events and mortality in a general population cohort?
Hazard Ratio: 1.43 (95% CI 1.25–1.63)
p-value: p=<0.01
Increased visit-to-visit variability in systolic blood pressure is an independent risk factor for future cardiovascular events and total mortality, regardless of mean blood pressure.
Choi et al. (2016) conducted a cohort in Cardiovascular outcomes (n=51,811). Visit-to-visit systolic blood pressure variability (SD-SBP ≥10 mm Hg) vs. SD-SBP <10 mm Hg was evaluated on Cardiovascular events or death (HR 1.43, 95% CI 1.25-1.63, p=<0.01). Visit-to-visit systolic blood pressure variability (SD-SBP ≥10 mm Hg) was associated with an increased risk of cardiovascular events or death (HR 1.43; 95% CI 1.25-1.63; P<0.01).
