[The influence of vitamin C and e or beta-carotene on peroxidative processes in persons with myocardial ischemia].

Le résumé fourni par la source

An increasing body of evidence suggests that beside hypercholesterolemia peroxidative processes and natural antioxidant defence system play important role in the development of atherosclerosis. Our earlier investigation showed the increased intensity of the peroxidative processes in the course of the acute myocardial infarction and unsatisfactory tocopherol, ascorbic acid and retinol status. The purpose of the present study was the evaluation of the effect of antioxidant vitamins supplementation by the period of 21 days on the peroxidative processes in patients after heart attack or after "bypass" admitted to the cardiological rehabilitation centre. Daily oral supplementation with vitamin C, E and beta-carotene decreased significantly plasma lipid peroxide concentration (TBARS). The highest drop in TBARS activity was found in the group after bypass. No significant effect of vitamin supplementation was observed on antioxidant enzymes activity.
