- Sleep apnoea is independently associated with increased risk for acute ischaemic stroke and poor functional outcome.
- An association was also observed between sleep apnoea and other known stroke risk factors like hypertension.
Why this matters
- Considering sleep apnoea in patients with acute ischaemic stroke could improve chances of recovery and reduce the risk for recurrence.
- This prospective observational study evaluated 102 consecutive patients with acute ischaemic stroke with hemiplegic upper limb.
- Sleep disordered Questionnaire, Berlin Questionnaire and Epworth sleepiness scale assessed sleep apnoea.
- Functional outcome was measured using Barthel score.
- Funding: None disclosed.
- 31 (30.3%) patients had sleep apnoea.
- Presence of hypertension was more in the apnoea vs no apnoea group (64.5% vs 43.6%; P=.052).
- Gain in mean Barthel score at the end of 3 months showed significant improvement in patients with no sleep apnoea (P<.001 suggesting an association between sleep apnoea and increased risk for ischaemic stroke.>
- Single-center study.
- Polysomnography not done to establish the diagnosis of sleep apnoea.
