Characterizing Mortality and CVD for Co-Morbid Insomnia and Sleep Apnea (COMISA) in the Sleep Heart Health Study

Overview/Abstract What is the problem being addressed? Insomnia and obstructive sleep apnea commonly co-occur (COMISA). Their co-occurrence has been associated with worse cardiometabolic and mental health. However, it remains unknown if people with COMISA are at a heightened risk of incident cardiovascular events and all-cause mortality. Keep reading

Arousal Burden is Linked with Long-Term Cardiovascular and All-Cause Mortality

Guest Blogger: Mattias Baumert Overview What is the problem being addressed? Our objective was to quantify the burden of cortical arousals throughout sleep and determine its association with long-term cardiovascular (CV) and overall mortality. What was the approach to solving the problem? We quantified arousal burden (AB) as the cumulative duration of all arousal events relative to total sleep time in three large cohort studies.
