ABSTRACT
Cor pulmonale frequently develops in patients with restrictive lung disease and neuromuscular
disorders. Sleep disordered breathing, including nocturnal hypoventilation and obstructive
apnea, has been associated with the development of cor pulmonale and may affect morbidity.
The mechanisms responsible for sleep disordered breathing include defects in the control
of breathing, respiratory muscle dysfunction, and abnormalities in chest wall and
lung compliance. Symptoms of disturbed sleep may allow patients with sleep disordered
breathing to be appropriately diagnosed and treated, often with nocturnal ventilation,
before the development of right-sided heart failure.
