Overview
Brief Summary
The purpose of this research is to determine how frequently sleep disorders such as sleep disordered breathing and insomnia occur in patients with coronary artery disease enrolled in cardiac rehabilitation. By reviewing results of a variety of tests, we also hope to learn more about the cardiovascular effects on people who may have these conditions.
Detailed Description
Patients referred to the Mayo Clinic Rochester CR and meeting eligibility criteria (see Subjects section below) will be recruited and consented. Prior to beginning CR, enrolled patients will undergo baseline sleep and CV assessment at the Clinical Research and Trials Unit (CRTU). Home-based sleep monitoring will take place. Patients will also complete additional cardiometabolic and behavioral evaluation as part of the standard CR clinical care. Following completion of the 12-week CR program, a post-CR assessment may be conducted, including the same set of tests/procedures. All patients will be followed up for at least 6-months following enrollment to monitor cardiac recurrence, hospitalization and death.

Outcomes
Primary Outcomes
The combination of both sleep disorders will be associated with more detrimental CV risk markers (lipids) than either sleep disorder alone
Time Frame: 6 months
To assess whether post-MI CR patients with comorbid SDB and insomnia exhibit a more unfavorable CV profile than those without.
The combination of both sleep disorders will be associated with lower adherence to CR - exercise
Time Frame: 6 months
To determine whether post-MI CR patients with comorbid SDB and insomnia show less adherence to the exercise prescription than those without
The combination of both sleep disorders will be associated with lower adherence to CR - number of attended sessions
Time Frame: 6 months
To determine whether post-MI CR patients with comorbid SDB and insomnia show less adherence to CR attendance than those without
The combination of both sleep disorders will be associated with more detrimental CV risk markers (blood pressure) than either sleep disorder alone
Time Frame: 6 months
To assess whether post-MI CR patients with comorbid SDB and insomnia exhibit a more unfavorable CV profile than those without.
The combination of both sleep disorders will be associated with lower adherence to CR - dietary prescription
Time Frame: 6 months
To determine whether post-MI CR patients with comorbid SDB and insomnia show less adherence to dietary recommendations than those without
The combination of both sleep disorders will be associated with more detrimental CV risk markers (cardiorespiratory fitness) than either sleep disorder alone.
Time Frame: 6 months
To assess whether post-MI CR patients with comorbid SDB and insomnia exhibit a more unfavorable CV profile than those without.
To examine the prevalence of comorbid sleep disordered breathing and insomnia in post-MI patients enrolled in cardiac rehab.
Time Frame: 6 months
Comorbid SDB and insomnia will be highly prevalent (\>30%) in this population. Measured by home, overnight polysomnography
The combination of both sleep disorders will be associated with more detrimental CV risk markers (depression) than either sleep disorder alone
Time Frame: 6 months
To assess whether post-MI CR patients with comorbid SDB and insomnia exhibit a more unfavorable CV profile than those without using the PHQ-9.
The combination of both sleep disorders will be associated with lower adherence to CR - adherence to pharmacotherapy
Time Frame: 6 months
To determine whether post-MI CR patients with comorbid SDB and insomnia show less adherence to prescribed medications than those without
