Myocardial involvement is a known complication of neuromuscular diseases and is a leading cause of morbidity and mortality in these disorders. Identifying patients early using cardiac function tests helps understand the mechanisms underlying cardiac involvement and may help limit the progression of cardiac disease before the onset of significant symptoms and limitation.
