Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

There is increasing evidence that inflammation plays a role in progression and destabilization of atherosclerotic plaque. FDG-PET can visualize activated metabolic activity of inflammatory cells. It is possible that FDG-PET can detect atherosclerotic plaque inflammation and that FDG-PET can monitor the effect of pioglitazone on plaque inflammation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Atherosclerotic patients with impaired glucose tolerance and type 2 diabetes will undergo the FDG-PET/CT imaging at baseline and again following 4 months after treatment. Patients who meet eligibility criteria will be titrated up to a maximum of 30 mg/day pioglitazone or 4 mg/day glimepiride. Physical examinations will be done at baseline, 4 months, and 12 months. During study, subjects will have body weight, and vital signs (HR, BP, etc) assessed as well as waist circumference. Laboratory assessments will be done at each baseline, 4 month.
