[Diagnostic implications of changed red cell count in low-intensity laser radiation of blood in elderly patients with coronary heart disease].

Intravenous laser therapy in combination with medication was conducted in 41 elderly patients with coronary heart disease (633 nm, 1 mW, 124 mW/cm2). The study of qualitative and quantitative (osmotic resistance) erythrocyte indices of blood demonstrated the change of erythrocyte number in circulating blood by the third laser procedure. Frequency of these changes correlated with duration of the treatment course. Intravenous laser therapy had a wider spectrum of effects on erythrocyte number than medication. Changes in erythrocyte number in the peripheral blood upon intravenous laser radiation reflects efficiency of treatment of coronary heart disease patients.
