Late-life, visit-to-visit blood pressure variability and its association with sex-specific long-term cognitive outcomes.

ABSTRACT: In 19 114 community-dwelling older adults enrolled in the ASPREE trial, high late-life visit-to-visit blood pressure variability (BPV) was associated with increased risks of incident dementia and cognitive decline during the median 4.7 year trial period. Whether sex or apolipoprotein E (ApoE) affect these associations over longer-term follow-up is unknown. We investigated the association between BPV and long term risks of dementia and cognitive decline using data from the ASPREE-eXTension (ASPREE-XT) study (median 8.3 year follow-up for dementia, 7.3 years for cognitive decline, after BPV estimation). Long-term BPV was estimated using standard deviation (SD) of the mean systolic BPs measured at ASPREE baseline, year 1 and 2 visits. Incident dementia was an adjudicated secondary endpoint an
