Arrhythmias & electrophysiologyCohort study
Day-to-day home blood pressure variability and risk of atrial fibrillation in a general Japanese population: the Hisayama Study
- Prospective cohort study
- community-dwelling
- 10-year follow-up
Authors' 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.
Study context
- Population
- Community-dwelling Japanese aged ≥40 years without prior AF (Hisayama Study)134 developed new-onset AF
- Participants
- 2,829 participants
- Exposure
- Quartiles of day-to-day home systolic blood pressure (SBP) variability
- Outcome
- New-onset AF
- Follow-up
- 10 years (2007-17)
Main finding
Incident AF
Hazard ratio
2.20
95% CI 1.18–4.08
By group
Q4 vs Q1
HR 2.20 (95% CI 1.18–4.08)
As reported in the abstract
- Crude incidence trend across quartiles
- P for trend < 0.01
- Adjusted risk trend across quartiles
- P for trend = 0.02
Observational data: associations, not effects.
