Exclusion Criteria:

- Patient has history of myocardial infarction, stroke, coronary artery bypass surgery or other coronary, carotid, or cerebral revascularization procedure,unstable angina, or angioplasty within 1 month of Visit 1. - Patient has chronic heart failure defined by New York Heart Association NYHA) Classes III or IV.

- Patient has unstable hypertension (e.g., sitting systolic blood pressure >160 mm Hg or diastolic >100 mm Hg) at Visit 1.
- Any known clinically important bleeding or platelet disorder.
- Patient has history of ileal bypass, gastric bypass, other significant condition associated with malabsorption.
- Patient is HIV or hepatitis B positive.
- Patients with significantly elevated TSH at Visit 1 may be entered after consultation with and approval by the SPONSOR. Patients with a history of hypothyroidism, who are on a stable dose of thyroxine with normal TSH level at Visit 1 may be included.
- Patients on cyclical estrogen medications (Estrogen Replacement Therapy ERT] or oral contraceptives). Patients on non-cyclical estrogen replacement therapy or Selective Estrogen Receptor Modulator (SERM) may be included, but must be on a stable dose for at least 8 weeks prior.
- Patients with active neoplastic disease which compromises their general health, or who currently require chemotherapy or radiation therapy, or who have completed chemotherapy or radiation therapy within 3 months prior.

5. Study Description
Brief Summary
Part A. The purpose of this study is to assess the effects of 6 weeks of treatment with, simvastatin, losartan or pioglitazone compared to placebo on the RNA expression profile of lower extremity peripheral arterial atherosclerotic plaque. Part B. The effect of simvastatin, losartan or pioglitazone compared to placebo on protein and lipid biomarkers in lower extremity peripheral arterial atherosclerotic plaque.
Detailed Description
This is a multi-center, randomized, double-blind, placebo-controlled, 6 week study. The study consists of 3 separate sub-studies in which patients undergoing bilateral lower extremity peripheral artery atherectomy will receive one of three FDA approved drugs known to have beneficial effect on the risk of cardiovascular disease. Patients will be selected for the particular sub-study based on a series of entry criteria and then randomized to the particular agent or placebo for 6-weeks.
