Clinical features, haemodynamics, and outcomes of heart failure with preserved ejection fraction in coarctation of aorta
Main finding · Death/transplantResult — go to the resultHazard ratio 1.68 95% CI 1.16–3.11Authors' 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
Methodological detailsconsecutive patients
