Pilot Study of Cardiac MR in Patients With Muscular Dystrophy

September 19, 2023 updated by: Christopher Spurney, Children's National Research Institute

Pilot Study of Cardiac Magnetic Resonance in Patients With Muscular Dystrophy

Muscular Dystrophy can affect the skeletal muscles and also the heart and breathing muscles, causing significant morbidity and mortality. As patients are now living longer, treatment of muscular dystrophies involves drugs that help improve heart function. However, better types of heart imaging studies are needed to understand how these treatments work. Researchers want to improve heart imaging to identify earlier indicators of heart dysfunction in muscular dystrophy patients and how these are changed by medical treatment. The new imaging indicators will also help identify candidates for entry into future clinical trials.

Study Overview

Detailed Description

Cardiomyopathy causes significant morbidity and mortality in multiple forms of muscular dystrophy affecting children, including Duchenne muscular dystrophy (DMD), Becker muscular dystrophy (BMD) and subtypes of autosomal recessive limb-girdle muscular dystrophy (LGMD2). Pharmaceutical treatments for the cardiomyopathy of muscular dystrophy, including angiotensin-converting enzyme (ACE) inhibition and beta-adrenergic receptor blockade, afford significant benefit and demonstrate cardiac remodeling in clinical studies. Further studies are needed to identify and characterize more sensitive indicators of cardiac dysfunction in muscular dystrophy subjects to better stratify subjects for entry into clinical protocols.
