[Intravenous use of low-energy helium-neon laser irradiation in unstable angina].
The effects of low-energy He/Ne laser on some functional characteristics of cardiac activity have been examined in 90 patients with unstable angina pectoris. Altogether 618 sessions of venous blood irradiation have been carried out. A random-sample reference group consisted of 25 patients. Antianginal effect has been assessed by the number of anginal attacks and by the number of daily nitroglycerin tablets. Exercise tolerance has been examined by paired bicycle ergometry; the ventricular rate activation parameters have been examined by the ECG technique and its first derivative. The data evidence a true antianginal clinical effect of intravenous laser therapy, increase of exercise tolerance in respect of both the total exercise performed and the time increment, and an essential acceleration of the ventricular activation in the patients with unstable angina.
