Factors Associated With Decision Tree Analysis In Coronary Heart Disease Angina Pectoris Card Syndrome Distribution Laws Of The Research

Purpose: 1,summed up Distribution of coronary heart disease syndrome, syndrome factor composition and status;2,to explore the study of disease syndromes distribution method.Material and method:This study used cross-sectional observation. Series of random sampling used to Jan. 2009～Nov.2009 treatment at University Hospital of Traditional Chinese Medicine, Liaoning, Liaoning, Second Affiliated Hospital of Traditional Chinese Medicine (TCM Research Institute of Liaoning Province), Liaoning Thrombus Treatment Center of Integrative Medicine Medical Center, Chinese and Western Medicine Hospital of Dalian, Fushun City hospital of Chinese medicine, Chinese medicine hospitals in Dandong City, Yingkou City Chinese Medicine Hospital, Second Affiliated Hospital of China Medical University (Mukden Hospital), China Academy of TCM Affiliated Xiyuan Hospital, Affiliated Hospital of Nanjing University of Traditional Chinese Medicine , Shenyang Military General Hospital, 11 Hospital or (and) patient 497 cases of angina pectoris were enrolled, one-time acquisition in patients with demographic data, medical history, risk factors, physical examination, the incidence and the incidence of solar terms, Traditional Chinese Medicine by inspection, Chinese Smelling and Hearing, Chinese Clinical symptoms, tongue, pulse and other information. Obtained by the epidemiological investigation of four diagnostic information in patients with purification,extraction frequency is greater than 15% of the symptoms and tongue and pulse information, factor analysis, respectively. Then, the load factor>0.4 for factor extraction. Next, the Chinese medicine theory, factor analysis of symptoms by factor 1 and all of tongue and pulse analysis of factors related to the minimum support threshold is 3%, minimum confidence threshold of 70% for rule extraction; The rest of the symptoms of traditional Chinese medicine theory to determine significant factors and all of tongue and pulse analysis of factors associated respectively to the minimum support threshold is 4%, minimum confidence threshold of 75% for rule extraction. Based on traditional Chinese medicine theory, the above rules obtained by the association determined syndrome to determine the distribution of angina pectoris syndrome and syndrome composition.Used as criteria for the selected 497 cases of angina pectoris syndrome in patients with type re-determination, the decision tree simulation, in order to constitute a concise syndrome, the symptoms of the syndrome to establish the diagnosis of status. Thus be summed up an effective distribution of disease syndromes research methods.Results:Decision tree analysis based on association and the results of standard reference line and the guiding principles, summed up the common coronary heart disease syndromes have four, that is, Qi Deficiency, Qi phlegm obstruction, weak heart yang qi deficiency syndrome and heart cards . Qi Deficiency - veinlets, fever, dizziness, drowsiness, less gas, or short breath, cough, a color pale, sunken pulse, afternoon or evening and consciously low heat, and eat less poor appetite, purple lips, constipation, low voice ; Qi and phlegm obstruction - Shibuya veins, veinlets, trapped body weight, chest tightness, or even a little labor; Weak heart yang Pass - chest pain, chest pain or very little labor, chest tightness, chest tightness, labor that is even slightly less gas lazy words, Shenpi, fatigue, looking Shaohua or minimalist, body weight difficulties, limb coldness, chills, language the sound was low, boring pale mouth, sunken pulse, astringent pulse, small pulse; Heart qi deficiency syndrome - heart pain, recurrent, chest tightness, shortness of breath, moving the breath, palpitations, easy to sweat, fatigue lazy words, white complexion. Light or dark tongue with scalloped thin white fur, weak pulse,or knot generation.Conclusion:1,coronary heart disease there are four common syndromes, namely Qi Deficiency, Qi and phlegm obstruction, weak heart yang qi deficiency syndrome and heart cards to the main deficiency. 2,in the frequency analysis and factor analysis on the basis of reducing the dimension, the correlation analysis, combined with clinical experts to conclude the disease of TCM syndrome distribution and composition. The association results for the standard cases of selected syndromes re-determine, based on this decision tree analysis, combined with clinical expertise in condensed form syndromes, constitute a factor in determining the status syndrome. The method of distribution of diseases, syndromes of a feasible and effective method.3,the study of disease syndromes in the distribution process, qualitative and quantitative imperative.
