  2. History of any atherosclerotic disorder (myocardial infarction, unstable angina, cerebrovascular accident, peripheral vascular disease or congestive heart failure secondary to ischemic myocardial injury) that would, in the estimation of the Investigator, make it unsafe to stop all lipid lowering drugs for up to 12 weeks during the course of the study.

These clinically significant medical conditions include, but are not limited to, uncontrolled hypertension, NYHA class III or IV CHF, proliferative diabetic retinopathy and neuropathic symptoms that limit activities of daily living.
  7. Participation in another clinical trial and/or treatment received with any investigational agent within one month before the initial dose of study medication.

  8. Concomitant therapy with the following: (See Appendix G for List of Drug Trade Names)

     1. weight loss medications
     2. oral or injected hypoglycemics (metformin is allowed) or insulin

     7. Subjects currently taking lipid lowering medications may be enrolled if the Investigator determines that the subject does not have any conditions that preclude cessation of lipid lowering treatment for up to 12 weeks. [All subjects will be required to discontinue all lipid lowering therapies during the 4 week Pre-Treatment Period and will then be randomized to receive either atorvastatin 10 mg or atorvastatin placebo during the first 8 weeks of the Treatment Period. All subjects will then receive atorvastatin 10 mg during weeks 8 to 16 of the Treatment Period.] Subjects may not be on any other lipid lowering agent through Visit 7 (Week 20) of the study.

(If all LFTs are WNL and total bilirubin is elevated, a retest of direct and indirect bilirubin may be performed. Subjects with indirect total bilirubin up to 3X ULN (presumed Gilbert's syndrome) may be enrolled if all other LFTs are WNL.)
  12. CK must not be >2.5X ULN if not clearly related to recent exercise, injury or unusual activity
