Brief Summary:
Veterans Affairs Cooperative Study #410, The Iron and Atherosclerosis Trial, FeAST, a 24-hospital prospective randomized single-blinded clinical trial of graded iron reduction was conducted between May 1, 1999 and April 30, 2005, and has now been completed. A total of 1,277 primarily male participants with peripheral arterial disease were entered. The primary outcome was all cause mortality and the secondary outcome combined death plus non-fatal myocardial infarction (MI) and stroke.

Condition or disease Intervention/treatment Phase
Atherosclerosis Intermittent Claudication Peripheral Vascular Diseases Procedure: Ferritin reduction to 25 ng/ml by phlebotomy Phase 3

Primary Outcome Measures :
  1. Mortality [ Time Frame: The minimum follow-up was 3.5 years and maximum follow-up was 6 years ]
    The primary objective of this study is to evaluate the effectiveness of a reduction of Total Body Iron Stores (TBIS) in decreasing the rate of all cause mortality in patients with peripheral vascular disease (PVD).

Ages Eligible for Study:   21 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  1. Males over the age of 21 years and post menopausal (either natural or surgical) females with a diagnosis of intermittent claudication who are not scheduled for major surgery and who can give informed consent will be entered.
  2. Hematocrit of 30% or greater for females and 35% or greater for males, normal liver function, serum creatinine less than 4 mg/dl. Patients with mild anemia and mild creatinine elevation will be entered (provided the anemia is not due to Fe deficiency found on screening laboratory tests) because such findings are commonly present chronically in PVD.
  3. Absence of a disturbance in Fe balance (e.g. hemosiderosis from any cause, hemochromatosis, atransferrinemia, PNH, Fe deficiency)
  4. Absence for at least six months of a disease that has caused bleeding (e.g. peptic ulcer, inflammatory bowel disease, hemorrhagic diathesis )
  5. Absence of associated neoplasm other than epithelial ( non-melanoma) tumors of skin or other co-morbid condition that is expected to be fatal within one year.
  6. Absence of an associated obvious inflammatory disorder (e.g. infection, connective tis-sue disease) capable of elevating ferritin levels acutely.
  7. Patients will not be excluded on the basis of either the existence or severity of either coronary- or cerebrovascular disease, medication use including non-steroidal anti-inflammatory drugs and anticoagulants, coronary angiographic findings, previous history of or possible future need for angioplasty or coronary bypass surgery, or elevated blood pressure.
  8. Patients must agree to not take any Fe supplements or vitamins while on study.

Exclusion Criteria:

1. Patients must have at least one lower extremity and must not be on another experimental therapy protocol for atherosclerotic vascular disease.
