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

Conditions
Sleep Disordered Breathing
Interventions
Other: screening
Registration Number
NCT02632162
Lead Sponsor
Zürcher RehaZentrum Wald
Brief Summary

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.

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
