简要总结
The aim of this randomized controlled trial is to test the effect of 12 weeks Adaptive Servo-Ventilation (ASV) therapy (additionally to optimal medical management of myocardial infarction) on myocardial salvage (MSI=myocardial salvage/area at risk, primary endpoint).
详细描述
Primary Outcome Measure: myocardial salvage index, MSI
- To test the effect of 12 weeks of ASV (additionally to percutaneous coronary intervention, PCI, and optimal medical management of AMI) on myocardial salvage (myocardial salvage index, MSI, assessed by cardiovascular magnetic resonance imaging, CMR).
Secondary Outcome Measures:
- To test whether ASV therapy in patients with SA early after AMI decreases infarct size and improves left ventricular remodelling (myocardial salvage, microvascular obstruction change of infarct size, infarct size at 12 weeks, change of left ventricular ejection fraction (LVEF), left ventricular systolic volume (LVSV), left ventricular diastolic volume (LVDV) and LVEF at 12 weeks; assessed with CMR).
B-type natriuretic peptide (NT-proBNP)
