Title: Women's Antioxidant and Folic Acid Cardiovascular Study (WAFACS)
Brief Summary: To determine if supplements of vitamin C, vitamin E, beta-carotene, and B-vitamins (a combination of folic acid, vitamins B6 and B12) reduce risk of major cardiovascular events in high risk women with a prior history of atherosclerotic cardiovascular disease. The trial is a companion to the Women's Health Study (WHS), a primary prevention trial of vitamin E and aspirin in a low risk population of women.

* Last menstrual period (LMP): ≥ 4 years
* Good general health
* Willingness to participate in this 4 year long study
* Able to give informed consent

The Hartford Institute for Geriatric Nursing recommends that a score of 23 or lower indicates cognitive impairment. (Accessed at www.harforddign.org). See appendix.
