AIMS: Several prospective studies have reported that higher visit-to-visit blood pressure variability (BPV) is associated with atrial fibrillation (AF). However, no studies have investigated the association between day-to-day BPV assessed by home blood pressure measurement and the development of AF.
METHODS AND RESULTS: A total of 2829 community-dwelling Japanese aged ≥40 years without prior AF were followed up for 10 years (2007-17). Day-to-day home BPV [defined as coefficient of variation (CoV) of home systolic blood pressure (SBP) for 28 days] was categorized into four groups according to the quartiles: Q1, ≤ 4.64%; Q2, 4.65-5.70%; Q3, 5.71-7.01%; Q4, ≥ 7.02%. The hazard ratios for developing AF were estimated using a Cox proportional hazards model. During the follow-up period, 134 participants developed new-onset AF. The crude incidence rates of AF increased significantly with higher CoV levels of home SBP: 2.1, 4.9, 5.2, and 8.8 per 1000 person-years in the first, second, third, and fourth quartiles, respectively (P for trend < 0.01). After adjusting for potential confounders, increased CoV levels of home SBP were associated significantly with a higher risk of AF (P for trend = 0.02). The participants in the highest quartile of CoV had a 2.20-fold (95% confidence intervals: 1.18-4.08) increased risk of developing AF compared with those in the lowest quartile.
CONCLUSION: The present findings suggest that increased day-to-day home BPV levels are associated with a higher risk of the development of AF in a general Japanese population.
