目的 :研究氦氖激光内关穴照射对老年冠心病患者循环系统的影响。方法 :老年冠心病患者 4 0例 ,采用氦氖激光照射内关穴 ,激光波长为 6 32 .8nm ,功率为 5mW ,15min/穴 ,1次 /d ,2 0次为 1疗程。治疗前 (Ⅰ )、首次治疗后即刻 (Ⅱ )和第一疗程结束后 (Ⅲ )检测血流动力学。结果 :Ⅰ与Ⅱ比较心脏总功率 (CWT)、左心排指数 (LCI)、心肌耗氧量 (CMO)、冠脉缺血阈值 (CMR)参数改善差异非常显著 (P <0 .0 1) ,左室有效功率 (LWE)改善差异有显著性 (P <0 .0 5 ) ;Ⅰ与Ⅲ比较 :CMO、CMR改善差异非常显著 (P <0 .0 1) ,CWT改善差异有显著性 (P <0 .0 5 )。结论 :氦氖激光照射内关穴治疗老年冠心病可改善患者心脏功能、冠脉循环和心肌耗氧量 ,是老年冠心病二级预防和治疗、控制病情发展的方便有效方法
Objective: To study the effects of He-Ne laser Neiguan irradiation on circulatory system in elderly patients with coronary heart disease. Methods: A total of 40 elderly patients with coronary heart disease were treated with He-Ne laser at Neiguan acupoint. The laser wavelength was 632.8nm, the power was 5mW, 15min / acupuncture point, once per day and 20 times for one course of treatment. The hemodynamics were measured before treatment (Ⅰ), immediately after the first treatment (Ⅱ) and after the end of the first course (Ⅲ). Results: The differences of CWT, LCI, CMO and CMR between Ⅰ and Ⅱ were significant (P <0.01) (P <0.05). There was significant difference in improvement of LWE between the two groups (P <0.05). The comparison between Ⅰ and Ⅲ showed that the improvement of CMO and CMR was significant (P0.01), and the improvement of CWT was significant P <0. 05). Conclusion: He-Ne laser irradiation Neiguan acupoint treatment of elderly patients with coronary heart disease can improve cardiac function, coronary circulation and myocardial oxygen consumption, secondary prevention and treatment of coronary heart disease in elderly, convenient and effective way to control the progression of the disease
