Congenital heart diseaseCross-sectional study
Frailty and Cognitive Function in Middle-Aged and Older Adults With Congenital Heart Disease
- Cross-sectional study
- multicentre
- 11 countries
Authors' conclusion
Approximately one-half of included patients were (pre-)frail, and more than one-third experienced cognitive impairment. Frailty and cognitive dysfunction were identified in patients with mild CHD, indicating that these concerns extend beyond severe CHD.
Study context
- Population
- Adults aged ≥40 years with congenital heart disease (CHD)
- Participants
- 814 adults · 11 countries
- Outcome
- Frailty phenotype (Fried method) and cognitive function (Montreal Cognitive Assessment)
Main finding
As reported in the abstract
Frailty and cognitive dysfunction prevalence
Robust
52.3%
Prefrail
41.9%
Frail
5.8%
Cognitive dysfunction

Observational data: associations, not effects.
Further findings
Predictors of frailty (multinomial regression)
- Frailty associated with older age, female sex, higher physiologic class and comorbidities
- Mild heart defects more likely than complex lesions to be prefrail
- More prefrailty in middle-income than higher-income countries
Predictors of cognitive dysfunction (logistic regression)
- Cognitive dysfunction related to older age, comorbidities and lower country-level income
