Primary Outcome Measures:
  • Time from randomisation to first occurrence of cardiovascular death, non-fatal myocardial infarction, or non-fatal stroke (a composite cardiovascular outcome) [ Time Frame: from randomisation up to 60 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Time from rand. to first occurrence of an expanded composite cardiovascular outcome defined as either cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, cor. revascularisation, hospitalisation for unstable angina or heart failure [ Time Frame: from randomisation up to 60 months ] [ Designated as safety issue: No ]
  • Time from randomisation to all cause death [ Time Frame: from randomisation up to 60 months ] [ Designated as safety issue: No ]
  • Time from randomisation to each individual component of the expanded composite cardiovascular outcome [ Time Frame: from randomisation up to 60 months ] [ Designated as safety issue: No ]
