Clinical studies and literature on acupuncture-moxibustion for stable angina pectoris with definite acupoint selection were included through retrieving China National Knowledge Infrastructure（CNKI）,Wanfang Database and VIP in order to analyze the characteristics and rules of acupoint selection in acupuncture-moxibustion treatment for stable angina pectoris. It has been found that the acupoint selection of acupuncture-moxibustion prescriptions for stable angina pectoris focused on specific acupoints.The top 5 acupoints with the highest using frequency included Neiguan（内关PC 6）,Danzhdng（膻中CV17）,Xinshu（心俞BL 15）,Ziusanli（足三里ST 36） and Sanyinjiao（三阴交SP 6）. Acupuncture-moxibustion treatment of stable angina pectoris involved 12 meridians, mainly including the hand-jueyin pericardium meridian, the foot-taiyang bladder meridian, conception vessel, the foot-yangming stomach meridian, the foot-taiyin spleen meridian, and the hand-shaoyin heart meridian, etc., embodying the characteristics and rules of acupoint selection such as ＂highlighting the special treatment effect of acupoints＂ ＂selecting acupoints along the pericardium meridian, bladder meridian and conception vessel, combining the anterior and the posterior acupoints＂, ＂selecting the distal acupoints of spleen and stomach meridians, and focusing on specific acupoints＂, etc.展开更多
