There is experimental evidence that low levels of adiponectin are associated with more reperfusion injury. In addition experimental studies have demonstrated that endothelial progenitor cells may have a favorable effect on remodeling, mainly through stimulation of neo-revascularisation. Clinical data on these issues are lacking. This clinical project studies the role of adiponectin, endothelial progenitor cells and endothelial microparticles in the ischaemia-reperfusion process and the compensatory ventricular remodelling in a population of 250 infarction patients treated with primary PCI. If the role of these factors could be confirmed in this clinical setting, those factors might represent a new target for therapeutic interventions in AMI patients.

Primary Outcome Measures:
  • occurrence of reperfusion injury after succesfull primary PCI [ Time Frame: within 90 min after PCI ] [ Designated as safety issue: No ]
    Serial ECG measurements (before and after PCI to assess extent of ST segment resolution as marker of reperfusion injury

Secondary Outcome Measures:
  • Major cardiovascular event rate [ Time Frame: at 1 year ] [ Designated as safety issue: Yes ]
    combined endpoint of hospitalisation (or extension of hospitalisation) for heart failure and cardiac death in a period of one year
