Heart Imaging in Children With Muscular Dystrophy
A Pilot Study of Cardiac Magnetic Resonance in Patients With Muscular Dystrophy
Background:
- Muscular dystrophy can affect the muscles used for heart function and breathing. Treatment usually involves drugs that help improve heart function. However, better types of heart imaging studies are needed to improve treatment of heart problems related to muscular dystrophy. Better heart imaging methods are especially needed for children with muscular dystrophy. Researchers want to test different heart imaging methods in children with muscular dystrophy. They will look at cardiac magnetic resonance imaging (MRI) and standard heart function tests.
Objectives:
- To develop and test new methods for imaging the heart in children with muscular dystrophy.
Eligibility:
- Children and adolescents between 8 and 17 years of age who have muscular dystrophy.
Design:
- Participants will be screened with a physical exam and medical history.
- Participants will provide a blood sample at the start of the study. They will also have heart function tests before having the imaging study.
- Participants will have a cardiac MRI scan that will last up to 60 minutes. Some tests will require a MRI contrast agent (a drug that helps the image appear more clearly on the scan).
