چکیده

Background Duchenne (DMD) and Becker (BMD) muscular dystrophy (MD) are characterized by progressive peripheral muscular damage. The cardiac involvement is high and often complicated by severe heart failure and high mortality. Cardiovascular magnetic resonance (CMR) can identify early stages of cardiomyopathy, as presence of myocardial fibrosis (MF). Several studies have shown negative correlation between creatinophosphokinase (CPK) levels and worst stages of peripheral muscular dystrophy, but have not evaluated their possible association with myocardial damage. Our objective was to investigate CPK levels and magnitude of myocardial damage in patients with MD.

Myocardial Fibrosis Burden Predicts Left Ventricular Ejection Fraction and Is Associated With Age and Steroid Treatment Duration in Duchenne Muscular Dystrophy

BACKGROUND Patients with Duchenne muscular dystrophy exhibit progressive cardiac and skeletal muscle dysfunction. Based on prior data, cardiac dysfunction in Duchenne muscular dystrophy patients may be influenced by myocardial fibrosis and steroid therapy. We examined the longitudinal relationship of myocardial fibrosis and ventricular dysfunction using cardiac magnetic resonance in a large Duc...

Serial assessment of myocardial T2 in Duchenne muscular dystrophy

Background Duchenne Muscular Dystrophy (DMD), a lethal X-linked skeletal and cardiac myopathy, affects 1/3500 males[1-2]. MRI studies have shown occult ventricular dysfunction and myocardial fibrosis in DMD patients. Previously we used the Full Width of Half Maximum (FWHM) of T2 distribution in LV to quantify the myocardial structural heterogeneity in DMD patients. In DMD subject groups, we sho...

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...

Quantitative left ventricular rotational mechanics in Duchenne and Becker muscular dystrophy patients

Background Duchenne/Becker muscular dystrophy (D/BMD) is associated with early onset cardiomyopathy, with cardiac fibrosis amongst the earliest manifestations. Changes in conventional estimates of cardiac function (e.g. ejection fraction, EF) may occur late in Duchenne and Becker muscular dystrophy (DMD/BMD). Cardiac MRI tagging is a noninvasive imaging biomarker for quantifying ventricular dys...

T1 mapping is abnormal before decline in EF in patients with Becker and Duchenne muscular dystrophy

Background Patients with Duchenne muscular dystrophy (DMD) develop cardiomyopathy (CM) at an earlier age compared to Becker muscular dystrophy (BMD), but the age of onset within each diagnosis is variable. A method to predict CM onset associated with dystrophinopathy could alter therapeutic approaches and improve outcomes. Shortened post-contrast T1 relaxation times are an early marker of myoca...
