Congenital heart diseaseCohort study

Pre-existing maternal cardiovascular disease and the risk of offspring cardiovascular disease from infancy to early adulthood

Eur Heart JPublished

  • Nationwide cohort study
  • register-based
  • negative control (paternal cardiovascular disease (CVD))

Authors' conclusion

Maternal CVD was associated with an increased risk of CVD in offspring during childhood and young adulthood.
