Heart dysfunction is common, and maternal carriers may be affected too.
SAVANNAH, Georgia — Heart problems are common in the vast majority of neuromuscular disorders, and cardiac monitoring of patients is crucial, even at younger ages, a neurologist told an audience of nerve/muscle specialists.
Cardiac problems are universal in DMD by age 18, he said. “Men and boys are living longer, so they have the opportunity to develop the cardiac abnormalities that accrue with time.” Conduction abnormalities typically appear first. “In a lot of these boys, you’ll typically see persistent sinus tachycardia. But they can also develop atrial arrhythmias and bundle branch blocks.”
Most boys will get echocardiograms, he said, “but there’s a lot of evidence showing that cardiac MRI is probably preferable for a number of reasons,” including better visualization. But the need for sedation limits access, he said, and cardiac MRI may not be available at some facilities.Cardiac involvement is more common and more severe in BMD than in DMD. About 50% deaths in BMD are attributed to malignant arrythmias or congestive heart failure, he said.
