Sleep apnea is common in people with heart disease and can worsen heart health if left untreated. This study is comparing two approved treatments for sleep apnea: a CPAP machine (which uses air pressure to keep airways open) and a mandibular advancement device (a custom dental mouthpiece that repositions the lower jaw). Researchers want to measure how well people stick with each treatment and how comfortable they find it over 6 months.
While CPAP machines are the standard sleep apnea treatment, many patients find them uncomfortable or difficult to use regularly. The dental mouthpiece is often easier to tolerate, but researchers need to confirm how well patients actually use it and whether it works as well for people with heart disease.

If you join, you'll receive either a CPAP machine or a dental mouthpiece (depending on which treatment you're already using or suited for), along with a dental exam and a sleep diary. Over 6 months, you'll wear your assigned device and the research team will track how consistently you use it. At the 6-month mark, you'll complete a phone interview where they'll ask about your experience, how well you've tolerated the treatment, and how it's affected your quality of life.
