The Effect of Interval Exercise on Functional Outcomes in Veterans With COPD and OSA

Summary

The term "Overlap Syndrome" (OS) is used to describe the presence of both chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) in a single patient. Due to premature aging, patients with OS are prone to developing functional decline up to 20 years earlier than the general population. The International Classification of Functioning, Disability and Health (ICF) evaluates functional status in chronic pulmonary disease globally in 5 domains. The investigators propose to study validated outcomes in 3 of these domains: 1) participation in life situations; 2) physical activity; and 3) cardiovascular health. The investigators long-term goal is to develop an exercise strategy tailored to Veterans with OS which will reduce the risk of functional decline through increased PA.

Eligibility

Inclusion Criteria:

* Diagnosis of COPD and OSA, i.e., Overlap Syndrome Diagnosis of Overlap Syndrome (both COPD and OSA), confirmed in CPRS from spirometry or pulmonary function test of FEV1/FVC \<70 for COPD and a polysomnogram or home-based study for OSA.
* Montreal Cognitive Assessment (MoCA) \>20

Exclusion Criteria:

* CAD, as defined by anyone of the following: history of CABG, prior positive stress test for ischemia, infarction or angina or medical problem
* Orthopedic problems as defined by joint pain limiting ambulation
* Fall risk, defined as more than 2 falls in the prior month
* Hospitalization in prior month
* Daytime home oxygen 6. Participation in structured exercise, defined by the Physical Activity Scale for the Elderly (PASE) as more than 1 hour of activity spent in moderate activity and any strenuous activity performed over prior 7 days.
