Why sleep matters for stroke
Population-level studies have established obstructive sleep apnea as an independent risk factor for first-time stroke and for stroke recurrence. The mechanisms — intermittent hypoxia, blood pressure surges, vascular inflammation, atrial fibrillation — overlap with the broader cardiovascular profile but are distinct enough that addressing sleep apnea adds measurable risk reduction.
Who should be evaluated
- Adults with treatment-resistant hypertension
- Patients with atrial fibrillation, particularly if persistent
- Post-stroke patients regardless of prior sleep history
- Patients with significant cardiovascular risk and any snoring or witnessed apnea
- TIA survivors during the immediate post-event window
Our evaluation
- Sleep medicine consultation with cardiovascular history
- Polysomnogram with attention to oxygen desaturation patterns and cardiac rhythm
- Coordination with cardiology and neurology when relevant
- Post-stroke patients: bedside or modified study protocols when needed
Treatment in this population
- CPAP — first-line for moderate-to-severe sleep apnea
- Positional therapy — when supine-predominant events are documented
- Adjunct cardiovascular optimization — coordinated with the patients primary cardiologist
- Long-term follow-up — quarterly review in the first year post-event
Treating sleep apnea after a stroke does not undo the event. But it can meaningfully reduce the chance of a second one.— Seoul Sleep Center cerebrovascular protocol
