Heart failure & cardiomyopathiesCohort study
Cardiomyopathies in children and adolescents: aetiology, management, and outcomes in the European Society of Cardiology EURObservational Research Programme Cardiomyopathy and Myocarditis Registry
- Prospective registry study
- multicentre
- 23 referral centres in 14 countries
Authors' conclusion
The findings confirm the heterogeneous aetiology of childhood cardiomyopathies and show a high frequency of familial disease. Outcomes differed by cardiomyopathy subtype
