Primary Outcome Measures:
  • ST segment resolution [ Time Frame: 90 min ] [ Designated as safety issue: No ]
  • Late loss (difference between minimal lumen diameter in stented segment immediately after and at 8 month follow up). [ Time Frame: immediately after and at 8 month follow up ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Restenosis [ Time Frame: 8 months ] [ Designated as safety issue: No ]
  • maximal elevations in blood concentrations of CK-MB enzyme and troponin-T [ Time Frame: Post procedure ] [ Designated as safety issue: No ]
  • wall motion index [ Time Frame: During hospitalisation: day 3-5 ] [ Designated as safety issue: No ]
  • Minimal lumen diameter [ Time Frame: 8 months ] [ Designated as safety issue: No ]
  • frequency of binary restenosis (>50% diameter stenosis), diameter stenosis (%) in the stented segment. [ Time Frame: 8 months ] [ Designated as safety issue: No ]
  • Occurrence of stent thrombosis and MACE. [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
