Eur J Prev CardiolPublished

  • Cross-sectional study

Authors' conclusion

A combined model of clinical and genetic risk factors explains only 36% of the likelihood of FHHD, implying additional value in the family history.

Study context

Population
UK Biobank participants without pre-existing CAD
Participants
166,714 participants
Outcome
Self-reported family history of heart disease (FHHD), associations with clinical and genetic risk factors and population attributable risks (PAR)
