Primary Outcome Measures:
  • Change in lipid pool volume from baseline to 18 months in response to atorvastatin 80mg.
  • Comparison of effect of atorvastatin 80mg versus 10mg

Secondary Outcome Measures:
  • Correlation of MRI measure of carotid morphology with cIMT measured by B-mode US.
  • Correlation of MRI measure of carotid morphology with DS-CT measure of coronary morphology.
  • Correlation of biomarkers to carotid changes.
