In Ontario, it is estimated that up to 80 per cent of individuals with sleep apnea remain undiagnosed, partly due to long wait times for assessment and diagnosis which require an in-hospital overnight sleep study. Over time, sleep apnea is associated with an increased risk of heart disease including high blood pressure, heart failure and stroke. Our scientists are conducting research to better understand the underlying pathophysiology of sleep apnea, to develop novel and nuanced approaches to diagnosis and treatment.
