Coronary Arteriosclerosis DC

Coronary arteriosclerosis is a form of myocardial ischemia, characterized by the thickening and loss of elasticity in the coronary artery walls. This results in cardiac dysfunction due to an imbalance between myocardial function and the capacity of the coronary vessels to supply sufficient blood flow. According to the diagnostic criteria made by the World Health Organization, coronary arteriosclerosis can be classified into five types: (1) primary sudden cardiac arrest, (2) angina pectoris, (3) myocardial infarction, (4) heart failure due to coronary heart disease, and (5) arrhythmia. In traditional Chinese medicine, the disease falls into the categories of xiong bi (obstruction of qi in the chest), xiong tong (chest pain), xin tong(precordialgia), zhen xin tong (myocardial infarction) etc.

The risk factors for coronary heart disease are hypertension, hyperlipemia, diabetes mellitus, and cigarette smoking. According to traditional Chinese medicine theories, it is held that the pathologic sites are the heart and lung. The causative factors include pathogenic cold or heat invasion of heart, impaired functions of the internal organs due to emotional strain, improper diet, asthenia of qi and blood, and hepatic and renal yin deficiency. The pathogenesis of coronary heart disease is attributed to a deficiency in origin and excess in superficiality. The manifestations of excess in superficiality are qi stagnation, blood stasis, accumulation of pathogenic cold, and phlegm stagnation. The manifestations of deficiency in origin are deficiencies of heart-qi, heart-blood and heart-yang, and hepatic and renal yin deficiency. In conclusion, the main pathogenic mechanism of the disease is the obstruction of the heart vessels.
