Detaljeret beskrivelse
Primary objectives:
To determine the time-course for the resolution of regional myocardial function after short-term coronary artery occlusion in patients with stable CAD who undergo PCI.
Secondary objectives:
- To confirm by cardiac magnetic resonance imaging that no myocardial injury occurs after short-term coronary occlusion in patients who undergo PCI due to stable CAD.
- To establish a clinical model for studying myocardial stunning.
