[Can vitamin E prevent development of coronary heart disease?].
Oxidation of low-density lipoprotein (LDL) probably plays an important part in atherosclerosis. Vitamin E (alpha-tocopherol) is a potent antioxidant carried in LDL. It increases the resistance of LDL to oxidation, thereby, among other things, inhibiting foam cell formation and proliferation of smooth muscle cells. Some animal experiments have indicated that vitamin E retards the development of atherosclerotic lesions. Observational studies (case-control and cohort) have shown that long-term treatment with vitamin E is associated with lower incidence of coronary heart disease in men and women alike. Randomisation to vitamin E in a large placebo controlled trial gave a nonsignificant reduction in mortality from ischemic heart disease. Although vitamin E seems to reduce the risk of coronary heart disease, randomised trials of adequate size are necessary in both secondary and primary prevention in order to test this. Such trials are in progress.
