Prevalence, Severity and Natural Course of Sleep Apnea After Cardiac Surgery

Prevalence, Severity and Natural Course of Sleep Apnea After Cardiac Surgery

Sleep disordered breathing (SDB) is common in cardiovascular patients. Patients after cardiac surgery will be screened for SDB with the ApnoeLink device at the beginning of cardiac Rehabilitation and then after 3 weeks and 3 months.

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

Inclusion Criteria:

• cardiac surgery or orthopedic surgery <2 weeks

Exclusion Criteria:

• known SDB
