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.
对90例不稳定型心绞痛患者研究了低能量氦氖激光对心脏活动某些功能特性的影响。共进行了618次静脉血照射治疗。随机抽样设立了一个由25例患者组成的参照组。通过心绞痛发作次数和每日硝酸甘油片服用量评估抗心绞痛效果。采用配对运动平板试验检测运动耐量；采用心电图技术及其一阶导数检测心室率激活参数。数据表明静脉激光治疗具有真正的抗心绞痛临床效果，在总运动量和运动时间增加方面运动耐量提高，不稳定型心绞痛患者的心室激活显著加速。
