Congenital heart diseaseCohort study

Clinical features, haemodynamics, and outcomes of heart failure with preserved ejection fraction in coarctation of aorta

Eur J Heart FailPublished

  • Retrospective cohort study
  • consecutive patients

Authors' conclusion

Heart failure with preserved ejection fraction is common in adults with COA and is associated with greater risk of death/transplant

Study context

Population
Adults with repaired coarctation of aorta (COA) who underwent right heart catheterization
Participants
99 adults
Exposure
Heart failure with preserved ejection fraction (HFpEF) vs no HFpEF in repaired COA
  • HFpEFn = 32
Outcome
Prevalence of HFpEF and death/transplant
