The purpose of this study is to determine whether FDG-PET is capable of detecting atherosclerotic plaque inflammation and monitoring the effects of statins on plaque inflammation. The usefulness of FDG-PET in risk stratification is also investigated.

Primary Outcome Measures:
  • attenuation of plaque inflammation (decrease in plaque SUV) at 3 and 12 months; cardiovascular events at 1 and 3 years [ Time Frame: 3 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • attenuation of circulating inflammation markers at 3 and 12 months [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • all cause death at 1 and 3 years; changes in carotid plaque index and plaque thickness [ Time Frame: 3 years ] [ Designated as safety issue: No ]

Arms Assigned Interventions
No Intervention: 1-1
Patients with FDG-positive plaque.
No Intervention: 1-2
Patients with plaque but not with FDG uptake.
Active Comparator: 2-1
Patients with FDG-positive plaque receiving statin therapy.
Drug: statins (pravastatin, simvastatin, fluvastatin, atorvastatin, pitavastatin, or rosuvastatin)
pravastatin 10-20 mg/day, simvastatin 5-10 mg/day, fluvastatin 20-60 mg/day, atorvastatin 10-40 mg/day, pitavastatin 1-4 mg/day, or rosuvastatin 2.5-20 mg/day
No Intervention: 2-2
Patients with FDG-positive plaque receiving diet management therapy.

Detailed Description:

There is increasing evidence that inflammation plays a role in progression and destabilization of atherosclerotic plaque. However, currently, no non-invasive method is available for detecting plaque inflammation in clinical practice. FDG-PET can visualize activated metabolic levels of not only tumor cells but also inflammatory cells. Thus, it is possible that FDG-PET can detect atherosclerotic plaque inflammation and that, if so, FDG-PET can monitor the direct effect of statins on plaque inflammation. Additionally, monitoring the plaque inflammation by FDG-PET may be useful for determining the risk stratification of atherosclerotic patients.

Comparisons: Patients with FDG-positive plaque, compared to patients with plaque but not with FDG uptake. Patients with FDG-positive plaque receiving statin therapy, compared to patients with FDG-positive plaque receiving diet management therapy.
