چکیده

Background Duchenne (DMD) and Becker (BMD) muscular dystrophy (MD) are inherited X-linked disease characterized by progressive skeletal muscle degeneration and myocardial involvement and caused by a mutation on dystrophin gene (Xp21). Dystrophin is a sarcolemal protein that links the cytoskeleton to the basal lamina and is essential for maintenance of the muscular membrane integrity during muscular contraction. In a previous study, our group described for the first time, in a small group of 10 patients, that CMR can identify myocardial fibrosis (MF) and may be useful for detecting the early stages of cardiomyopathy in MD [1]. The evolution of the myocardial fibrosis over time in this group of patient is still unknown.

Progression of myocardial fibrosis by magnetic resonance imaging in patients with Duchenne and Becker muscular dystrophy and preserved left ventricular ejection fraction - a randomized clinical trial for treatment with ACE inhibitors

Background Duchenne (DMD) and Becker (BMD) muscular dystrophies ( MD) are inherited X-linked diseases characterized by absence or decrease of dystrophin, a sarcolemal protein that is essential for maintenance of the muscular membrane integrity during muscular contraction. Cardiac involvement is as high, it can be clinically silent, but is often complicated by severe heart failure and high morta...

Cardiomyopathy in Becker muscular dystrophy--does regional fibrosis mimic infarction?

We present a case of a 39-year-old man with Becker muscular dystrophy and severe congestive cardiac failure. Cardiac magnetic resonance imaging revealed subendocardial late gadolinium enhancement, similar to that seen in myocardial infarction. He had no risk factors for atherosclerotic coronary artery disease and coronary angiography was normal. We propose that regional subendocardial myocardia...

Association between specific dystrophin gene mutations and myocardial fibrosis by cardiovascular magnetic resonance imaging in patients with Duchenne and Becker muscular dystrophy

Background Duchenne (DMD) and Becker (BMD) muscular dystrophies (MD) are allelic X-linked recessive disorders, caused by mutation of the dystrophin gene located at locus Xp21 that consists of 79 exons, characterized by progressive skeletal muscle degeneration and replacement by fibro fatty tissue. Dystrophin is a sarcolemal protein that links the cytoskeleton to the basal lamina and is essentia...

T1 mapping in Becker muscular dystrophy patients detects diffuse microfibrosis prior to evidence of late gadolinium enhancement or cardiac dysfunction

Background Becker muscular dystrophy (BMD) is allelic with Duchenne muscular dystrophy and represents a milder skeletal muscle phenotype; however, cardiac dysfunction remains a significant clinical problem. Cardiac involvement in BMD precedes skeletal muscular decline, and cardiomyopathy often leads to death before the age of 60 years. Cardiac magnetic resonance (CMR) is used for ventricular fu...

Myocardial delayed enhancement by magnetic resonance imaging in patients with muscular dystrophy.

OBJECTIVES This study sought to analyze whether cardiovascular magnetic resonance (CMR) can detect and quantify myocardial damage in the early stages of cardiomyopathy in muscular dystrophies (MD). BACKGROUND Muscular dystrophy is a genetic disease that involves skeletal and cardiac tissues of humans. Cardiomyopathy is common, and death secondary to cardiac or respiratory diseases occurs earl...
