Summary

This study looked at whether using a CPAP machine to treat sleep apnea soon after a stroke can improve heart health. 71 people with acute stroke and moderate-to-severe sleep apnea were randomly assigned to CPAP or usual care. Researchers measured changes in heart structure and blood markers over 12 months to see if CPAP reduces the risk of future heart problems or stroke.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: CPAP (continuous positive airway pressure) device
What this could lead to: If it works, CPAP could help reduce the risk of another stroke or heart problem in people who have both stroke and sleep apnea.
What could go wrong: This is a small, completed trial with 71 people, so results may not apply to everyone. CPAP can be uncomfortable and some people may not use it regularly.
