[The stress-limiting action of low-intensity laser radiation in patients with ischemic heart disease].

In 20 patients with exercise-induced angina, the cold test brought about activated lipid peroxidation, modified the lipid phase of a red cell membrane, which correlated with systolic changes. Following a month laser therapy, it did not cause no activation of lipid peroxidative processes, significant changes in the organization of a cell membrane lipid bilayer, or any profound cardiac performance abnormalities, which gives grounds to state that laser radiation exerts membrane-stabilizing and antistress effects. The findings suggest that laser therapy should be used in coronary heart disease patients having a functional component of coronary insufficiency.
