After a short review of the data on the free radicals occurring in the human body (hydroxyl radical, superoxide, nitric acid, peroxynitrite), the possible effects of these radical upon the cardiovascular system are presented. The preservation of the oxidants-antioxidants balance is highly important for preventing the cardiovascular diseases. Endogenous antioxidants are not 100 per cent effective, reason why for the individuals with atherosclerosis and ischemic heart disease antioxidant supplements (tocopherols, carotenes, vitamin C, selenium) are essential especially during the seasons when diets are deficient in fruits and vegetables.
