NCT00000541

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.
