Continuous Positive Airway Pressure, Myocardial Salvage, Obstructive Sleep Apnea, ST Elevation Myocardial Infarction
Brief summary
The aim of this randomized controlled trial to investigate the effects of CPAP treatment on myocardial salvage index and clinical outcomes at 3 months in patients with OSA and ST-Segment Elevation Myocardial Infarction (STEMI) after primary percutaneous coronary intervention (PPCI).
Interventions
The optimal continuous positive airway pressure (CPAP, AutoSet S9, ResMed, Sydney, Australia) settings will be determined during 1-2 nights within 7 days after pPCI.

Patients with contraindication to CPAP or who cannot tolerate it 14. Participation in other clinical trial in recent 3 months 15. Any condition that in the opinion of investigator that may jeopardize patient compliance, eg. significant memory, perceptual, or behavioral disorder, depression, severe alcohol consumption, or a history of noncompliance
