Question: Does two-year statin therapy alter the progression of intima-media thickness in patients with type 2 diabetes without manifest cardiovascular disease?
Answer: There was no effect of 2 years' statin therapy on carotid IMT in type 2 diabetic subjects. The natural history of IMT in our patients was milder than anticipated. In contrast, we observed a significantly lower cardiovascular event rate on statin therapy. Prognostic tools other than IMT should be explored in this patient group.
