Read our Stroke research guide →Researchers want to understand the connection between sleep apnea (a condition where breathing stops and starts repeatedly during sleep) and heart or stroke problems after a person has had an initial stroke or mini-stroke. This study will track 1,620 patients over five years to see if people with untreated sleep apnea have more cardiovascular events—like heart attacks, additional strokes, or cardiac death—compared to those without sleep apnea.
After a stroke, patients are already at higher risk for another stroke or heart attack. Scientists suspect that sleep apnea may make this risk even worse, but they need solid evidence to understand how big this problem is and to help doctors protect stroke patients better.

You will visit the hospital several times over five years. At your first visit (within 3 days of your stroke), the team will check your eligibility and get your consent. Within 6 months, you'll have a detailed baseline visit with clinical exams, brain imaging (MRI), blood tests, walking tests, and questionnaires about mood, sleep quality, and daily function. At 3 months, you'll have a sleep study (polysomnography) to diagnose sleep apnea, and repeat some tests and questionnaires. After that, you'll return for follow-up visits to monitor for heart or stroke events, with repeat assessments of your physical, cognitive, and emotional well-being throughout the five-year period.
