Eur J Prev CardiolPublished

  • Prospective cohort study
  • replication in independent cohort

Authors' conclusion

Socioeconomically deprived individuals have a significantly higher risk of AF, with this risk further influenced by genetic predisposition.

adjusted HR 1.16 (95% CI 1.09–1.24); P < 0.001

Observational data: associations, not effects.

Further findings

Incident AF, deprivation effect by genetic risk (polygenic risk score (PRS) tertile)

Deprivation effect, lowest PRS tertile (low genetic risk): aHR [95% CI]
1.36 [1.19-1.56]
Deprivation effect, highest PRS tertile (high genetic risk): aHR [95% CI]
1.11 [1.01-1.22]
  • interaction P=0.0013

Incident AF by Index of Multiple Deprivation (IMD) component

Most IMD components (except housing and living environment) linked to increased AF risk: aHR range
1.13 to 1.19

Replication in Korean cohort

Results consistent in the Korean cohort (n)
7,898
