A Study to Evaluate Comorbid Insomnia and Sleep Disordered Breathing in Patients Undergoing Cardiac Rehabilitation


About this study

The objectives of this study are to examine the prevalence of comorbid sleep disordered breathing (SDB) and insomnia in post-MI patients enrolled in cardiac rehabilitation (CR), to assess whether post-MI CR patients with comorbid SDB and insomnia exhibit a more unfavorable CV profile than those without, and to determine whether post-MI CR patients with comorbid SDB and insomnia show less adherence to home-based CR than those without.
