Brief Summary:
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.

STEMI patients
Patients with ST elevation myocardial infarction,lasting <12 hour, who were succesfully treated with primary PCI

Primary Outcome Measures :
  1. occurrence of reperfusion injury after succesfull primary PCI [ Time Frame: within 90 min after PCI ]
    Serial ECG measurements (before and after PCI to assess extent of ST segment resolution as marker of reperfusion injury

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