Abstract
Myocardial dysfunction in 14 patients with Duchenne's muscular dystrophy (DMD) was evaluated by Tc-99m HSA multigated radionuclide ventriculography (MGRV). Follow- up studies were performed on eight patients for 5 years. Left ventricular ejection fraction and standard deviation of the phase angle were abnormal in all patients older than 15 years. Hypokinetic changes and phase delay were recognizable in most patients older than 17 years. Peak filling rate decreased in patients older than 17 years. MGRV was considered an effective method for evaluating serial changes in cardiomyopathy of patients with DMD.
