Cardiac autonomic control during sleep in patients with myotonic dystrophy type 1: the effects of comorbid obstructive sleep apnea

Myotonic dystrophy type 1 (DM1) is a hereditary myopathy characterized by an autosomal dominant inheritance with important cardiovascular and autonomic deregulation. DM1 patients have a high prevalence of obstructive sleep apnea (OSA), but the effects of this comorbidity on cardiovascular autonomic control (CAC) are unknown. The present study aimed to investigate CAC during sleep-wake cycle in DM1 patients, taking into account the effects of OSA comorbidity.
