Abstract: In 2023， the American Heart Association（AHA） issued a scientific statement on the treatment strategies for child cardiomyopathy， focusing on dilated and hypertrophic cardiomyopathies， which addresses the lack of treatment options for children-specific cardiomyopathies and provides options based on the AHA perspective. The purpose of this paper is to interpret this scientific statement in order to provide an AHA-based decision-making evidence for domestic colleagues to develop treatment programs for children with cardiomyopathies.
