Cardiac Ejection Fraction as Measured by Echocardiogram [ Time Frame: 12 month visit ]
Mean cardiac ejection fraction as measured by echocardiogram at 12 month study visit. Cardiac ejection fractions were measured using the biplane Simpson's rule using images obtained from the apical 4 chamber views of the heart.
Cardiac Ejection Fraction as Measured by Echocardiogram [ Time Frame: Every 4 months for 2 years ]
Participants will have a baseline visit and then followed every four months for the duration study, anticipated for a total of 2 years.

Not Provided
  • Skeletal muscle strength [ Time Frame: Every 12 months for 2 years ]
    Muscle strength will be measured by hand held dynamometer. Participants will have a measurement collected at their baseline visit and then again at their 1 and 2 year visits.
  • Skeletal Muscle function [ Time Frame: Every 12 months for 2 years ]
    Skeletal muscle function will be measured by Brooke Upper Extremity Functional Rating Scale, Nine-Hole-Peg test, and 6-minute walk test (6MWT). Participants will have a measurement collected at their baseline visit and then again at their 1 and 2 year visits.
Not Provided
  • Pulmonary function testing [ Time Frame: Every 12 months for 2 years ]
    Forced vital capacity (FVC) will be measured using a spirometer. Participants will have a measurement collected at their baseline visit and then again at their 1 and 2 year visits.
  • Changes in activities of daily living [ Time Frame: Every 12 months for 2 years ]
    Measured using the Egen Klassification (EK) Scale. Participants will have a measurement collected at their baseline visit and then again at their 1 and 2 year visits.
  • Health related quality of life [ Time Frame: Every 12 months for 2 years ]
    Measured using the PedsQL. Participants will have a measurement collected at their baseline visit and then again at their 1 and 2 year visits.
 
Cardiomyopathy in DMD: Lisinopril vs. Losartan
Compare Efficacy of the Angiotensin Converting Enzyme Inhibitor (ACEi) Lisinopril With Angiotensin II Receptor Antagonist Losartan (ARB) for the Cardiomyopathy of Duchenne Muscular Dystrophy
This trial is a double-blind randomized clinical trial of lisinopril versus losartan for the treatment of cardiomyopathy in Duchenne Muscular Dystrophy (DMD). Both drugs are known to be effective for the treatment of dilated cardiomyopathy. ACEi have been reported to delay the onset and progression of left ventricle dysfunction in children with DMD. Multiple studies show therapeutic efficacy of losartan in animals with cardiomyopathy related to muscular dystrophy and in patients with cardiomyopathy from diverse causes. ARBs are often reserved for patients in whom heart failure is not adequately treated or where side effects preclude the use of an ACEi. However, in DMD, losartan might be a better choice as a first line drug because of studies demonstrating a potential benefit for skeletal muscle in the mdx mouse. Considering that both skeletal and cardiac muscles are major contributors of the disability of DMD, a drug that could improve both heart and skeletal muscles simultaneously would need consideration as the drug of choice for the cardiomyopathic DMD patient.
