Other Name: Tricor

20 mg/day

Other Name: Lipitor

Detailed Description:

The study will compare the effect of atorvastatin to the effect of fenofibrate on endothelial function in patients with diabetes mellitus or the metabolic syndrome. The study is a double blind, placebo controlled, crossover study with the order of treatment randomized. Patients will receive each treatment for 8 weeks with a 1 week rest period between treatment periods. Endothelial function will be tested using non-invasive techniques before and after each treatments. A total of 40 subjects with diabetes or the metabolic syndrome will be enrolled at Boston Medical Center.

Able to provide informed consent and complete study procedures

Exclusion Criteria:

Change in therapy for glucose control or blood pressure less than 1 month before entry
Hemoglobin A1C greater than 8.0%.
Renal insufficiency (serum creatinine greater than 1.6 mg/dl in men or 1.5 mg/dl in women.
Any investigational drug less than 1 month before entry.

Patients with coronary artery disease, peripheral arterial disease, or cerebral vascular disease will not be enrolled if they are currently taking lipid-lowering therapy
Patients taking more than 40 mg/day of atorvastatin will be excluded. There is no "ceiling" level for patients taking fibrates.
