Further study details as provided by University of Freiburg:

Primary Outcome Measures:
  • Composite of Death, Myocardial Infarction and Target Vessel Revascularization [ Time Frame: up to 24 months ] [ Designated as safety issue: Yes ]
    The primary outcome is the above mentioned composite of adverse events in order to measure their cumulative incidence (i.e. the rate of occurrence of such events in the study population over a predefined time periode).

Secondary Outcome Measures:
  • Cardiovascular death [ Time Frame: up to 24 months ] [ Designated as safety issue: Yes ]
  • Any Revascularization [ Time Frame: up to 24 months ] [ Designated as safety issue: Yes ]

Primary Completion Date: November 2010 (Final data collection date for primary outcome measure)
everolimus-eluting stents (EES)
Second-generation everolimus-eluting stents (EES) have been shown to be superior to the first-generation paclitaxel eluting stents (PES) in terms of safety and efficacy.
biolimus-eluting stents (BES)
Third generation biolimus-eluting stents (BES) have been shown to be superior to the PES and non inferior to first-generation sirolimus eluting stents in terms of safety and efficacy.
