近年国外已开始采用氦-氖激光器照射(简称激光照射)治疗缺血性心脏病、胃和十二指肠溃疡病、下肢闭塞性血管疾病以及多发性关节炎等病症,并取得了较好的疗效。本文就激光照射治疗心绞痛的照射方法,疗效评价和作用机理等作一概述。一、照射方法采用氦-氖12-1型医用激光器,波长为0.63微米,照射面上的功率密度为0.2～0.4毫瓦/厘米~2。治疗时分别在胸骨区、心尖区和颈前区进行照射,直径为10～11厘米;每区照射1分钟,每天照射1次,共20天为一疗程。二、疗效评价小功率氦-氖激光照射对心绞痛有较好
In recent years, foreign countries have begun to use helium - neon laser irradiation (referred to as laser irradiation) for the treatment of ischemic heart disease, gastric and duodenal ulcer disease, lower extremity occlusive vascular disease and multiple arthritis and other diseases, and achieved better Efficacy. In this paper, the method of laser irradiation treatment of angina, efficacy evaluation and mechanism of action are summarized. First, the irradiation method using a helium-neon 12-1 medical laser, a wavelength of 0.63 microns, the irradiation surface of the power density of 0.2 ~ 0.4 mW / cm2 ~ 2. Treatment were in the sternal area, apical area and anterior cervical area for irradiation, a diameter of 10 to 11 cm; irradiation 1 minute per area, 1 day exposure, a total of 20 days for a course of treatment. Second, the efficacy evaluation Low-power helium-neon laser irradiation angina is better
