Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • Change in CFR peak velocity within rosuvastatin group after 1 month of treatment compared to baseline [ Time Frame: Baseline and after 1 month of treatment ] [ Designated as safety issue: No ]
  • Comparison of treatment effects on CFR peak velocities between groups after 1 month of treatment [ Time Frame: Baseline and after 1 month of treatment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Changes in CFR peak velocity within the rosuvastatin group after 3 months compared to baseline and to 1 month [ Time Frame: Bseline, after 1 month and after 3 months of treatment ] [ Designated as safety issue: No ]
  • Changes in other CFR parameters after one month rosuvastatin or placebo treatment; comparisons within groups and between groups [ Time Frame: Baseline and after 1 month of treatment ] [ Designated as safety issue: No ]
  • Changes in plasma lipids, lipoproteins and other cardiovascular biomarkers after 1 month of treatment with rosuvastatin or placebo; comparisons within groups and between groups [ Time Frame: Baseline and after 1 month of treatment ] [ Designated as safety issue: No ]
