Risk of heart failure in inflammatory bowel disease: a Swedish population-based study

Eur Heart JPublished

  • Population-based matched cohort study
  • nationwide
  • matched with up to five general population reference individuals
  • sibling-controlled analysis

Authors' conclusion

Patients with IBD had a moderately higher risk of developing HF for ≥20 years after IBD diagnosis than the general population.
