ABSTRACT
Pulmonary complications including chest infections, atelectasis, pulmonary hypoplasia
and ventilatory failure are the leading cause of death in the muscular dystrophies
and atrophies. Ventilatory insufficiency is virtually inevitable in Duchenne muscular
dystrophy and type 1 spinal muscular atrophy (SMA), but more variable in limb-girdle,
congenital, and facioscapulohumeral muscular dystrophy. A cardiomyopathy may complicate
Duchenne, Becker, and Emery-Dreifuss muscular dystrophies. Most patients respond well
to ventilatory support with reduced pulmonary morbidity and extended survival. Careful
monitoring and anticipation of complications are important so that ventilatory assistance
can be started in a timely fashion.
