[The Impact of the Intravenous He-Ne Laser Therapy on the Antioxidant System in Patient with Stable Exertion Angina and Postinfarct Cardiosclerosis]

The authors' study show that intravenous He-Ne laser therapy (HNLT) in patients with stable angina of effort (functional class II-III) and postinfarction cardiosclerosis irrespective of ejection fraction increased plasma katalase and red cell vitamin A concentrations. HNLT aroused vitamin E concentration in red cells in anginal patients with intact ejection fraction whereas in those with reduced ejection fraction it elevated blood peroxidase, plasma vitamin A and E concentrations. For patients with postinfarction cardiosclerosis there were, respectively, higher levels of blood peroxidase, plasmic vitamin A, red cell vitamin E, plasmic SH-groups and blood peroxidase, plasmic vitamins A and E.
