About this study

Objective(s) of the project

  • Evaluate the prevalence of sleep apnea after cardiac surgery
  • Compare results interindividually (group A vs. group B) and intraindividually (longitudinal assessment after 3 months)

Outcome(s)

  • Prevalence of sleep apnoe at day 1 and 20 of rehabilitation and 3 months after cardiac surgery
  • composite endpoint of events at 3 months (cardiovascular death, non-fatal myocardial infarction, non-fatal cardiac arrest, revascularisation procedure, new atrial fibrillation and stroke)
  • change in 6-minute walking test (6-MWT)
  • impact of heart surgery on sleep apnoe
