Detailed description

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
