Condition(s) studied

Investigational drug(s) / intervention(s)

Study summary

This prospective cohort study aims to compare the proportion of cardiac or cerebrovascular events after a first stroke, a first transient ischemic attack (TIA) or recurrent TIA, between sleep-disordered breathing (SDB) and non-SDB (control) patients, one year after SDB diagnosis, performed 3 months after stroke onset.

The primary outcome is a composite endpoint composed of cardiac or cerebrovascular events regrouping: death from any cardiac or cerebrovascular cause, non-fatal stroke, and non-fatal acute coronary disease.

1620 patients, in the acute phase of a first stroke, TIA or recurrent TIA will be included in the cohort.

Clinical, neuroimaging, sensorimotor, cognitive and biological parameters will be collected at inclusion. Three months after stroke or TIA onset, polysomnography will be performed for SDB diagnosis. Patients will be considered as having SDB for an Apnea-Hypopnea Index (AHI) \> 15 events/hour, or to the control group otherwise. The same clinical, imaging, cognitive and biological assessments than during the first visit will be performed; incident (new) cardiovascular events will be collected. Three months later, and at 1, 2, 3, 4 and 5 years after SDB diagnosis, the same clinical, cognitive, sensorimotor, and sleep-related evaluations will be performed. In addition to the aforementioned parameters, incident cardiovascular outcomes will be collected, at the same time points. The primary study outcome will be retrieved one year after stroke onset.

Eligibility

Primary outcome measure(s)

• Prevalence of Major Adverse Cardiac or Cerebrovascular Events (MACCEs) — 1 year after SDB diagnosis
  Composite endpoint composed of cardiac or cerebrovascular events regrouping: death from cardiac of cerebrovascular cause, non fatal stroke (either ischemic or hemorrhagic), and non-fatal acute coronary disease
