The syndrome refers to pectoral pain with stuffiness. In mild cases, the patient feels chest suffocation and in severe cases, experiences colic pain, shortness of breath and asthmatic breathing. The factors causing it are mostly the accumulation of yin cold and obstruction in the meridians and collaterals occurring in the aged with qi deficiency of the heart and lung and the hypo-activity of chest yang, invaded by exogenous pathogenic cold; or chest yang is blocked by phlegm. Other factors are obstruction of qi activities, which happens when the dampness, produced by the spleen deficiency due to the improper food intake or over-intake of greasy and high flavored food, has accumulated and turned into phlegm; or prolonged stagnation of liver qi has impaired the smooth flow of blood and produced stagnation of qi and blood. The treatment principle is to regulate qi activities. Points of the conception vessel, Jueyin meridians and Back-shu points are selected, such as: Xinshu (BL15), Jueyinshu (BL14), Tanzhong (CV17), Juque (CV14) and Neiguan (PC6). In the case of hypo-activity of chest yang, Feishu (BL13), Qihai (Ren 6), Guanyuan (Ren 4) and Ximen (PC4) are combined, and the moxibustion is also used in the treatment. In the case of the retention of phlegm damp, Pishu (BL20), Zhongwan (Ren 12), Zusanli (ST 36) and Fenglong (ST 40) are used; for stagnation of qi and blood, Geshu (BL17), Yinxi (HT6) and Taichong (LR 3) are adopted. The reducing technique is used to treat the excess syndrome, while the reinforcing technique is used to treat the deficiency syndrome. Chest pain can be found in some Western medical diseases, including the coronary arteriosclerosis, cardiopathy and other acute and chronic cardiopulmonary diseases.
