Coronary Syndrome Factor

Purpose: This study used the decision tree, frequency and other methods of mathematical statistics were coronary syndromes 1218, elements of syndrome features, pathogenesis of syndrome evolution of clinical three-dimensional structure of the questionnaire of experts associated with the database for statistical analysis confirmed the spleen yang deficiency The main four stages of coronary heart disease syndrome elements and evolution of dynamic observation of the pathogenesis of syndrome and the various relationships. This helps to block the pathological development ahead of trends, more guidance on the clinical diagnosis and treatment, but also the advantages of Chinese medicine treatment of coronary heart disease expression.Material and method: We characterized the symptoms of coronary heart disease patients as research subjects, to Chinese medicine theory, theory of modern psychological measurement, and the introduction of structured decision-making, the development characteristics of coronary heart disease syndromes and Change Rules Experts line questionnaire. The questionnaire used both open and closed methods combining the use of three Delphi rebuilt, to reliability, validity, excellent. Northeast of the country, north, northwest, southeast, southwest and south six regions and 41 hospitals conducted a questionnaire survey, 1218 were eligible questionnaires were collected by using computer equipment to establish a database Access questionnaire, a questionnaire entry and secondary verification, the eventual establishment of crown heart syndrome factors, syndrome features, pathogenesis of syndrome evolution of clinical experts, three-dimensional structure of the questionnaire associated with the database, using the SAS statistical analysis software, the use of frequency, decision trees and neural networks and other mathematical statistical methods for statistical analysis. Results:1.Coronary syndrome factor in the four main stages of the frequency results: Spleen deficiency syndrome factor in the four stages (early onset, exacerbation, remission, recovery) in order of frequency distribution: 36%,87%,66%,36% .From early onset to the onset of a sharp increase in frequency, the highest attack, to alleviate the overall balance of the decline and recovery was to show condition changes from prosperity to decline trends.2.Coronary syndrome the main elements and results of syndrome: Spleen deficiency syndrome factor in the pathogenesis of early Qi Deficiency, Qi stagnation heart cards, heart attack Yang in the weak card, Hanning Xinmaitong card, micro card stasis Yang, Qi stagnation heart cards, heart and lung in remission Qi deficiency, liver and spleen does not transfer card, heart deficiency syndrome, the gas shortage in the heart of recovery certificate, Qi Deficiency, Yang and Qi stagnation The frequency distribution of cards in the 7.82% a 95.04% in between; the other hand, the syndrome of the spleen yang deficiency syndrome factor in the frequency distribution in the 8.53% a 80.33% in between. From early onset to the onset of a sharp increase in frequency, the highest attack, to alleviate the overall balance of the decline and recovery was to show condition changes from prosperity to decline trends.3.Decision Tree results show that coronary heart disease the major elements of spleen yang deficiency syndrome four phases of coronary heart disease (early onset, exacerbation, remission, recovery) of the judge rules, the neural network training showed more consistent results predicted, both the training set or validation set to assess the set reached 40% correct rate for a 76%.Conclusion:1.Questionnaire Development.Characteristics of the symptoms of coronary heart disease patients as research subjects, to Chinese medicine theory, theory of modern psychological measurement, and the introduction of structured decision-making, the preparation of a coronary syndromes and their evolution characteristics of first-line expert questionnaire open and closed in two ways by combining and using the Delphi method and content of rehabilitation of the structure of the questionnaire. Aims to summarize the characteristics of syndromes of coronary heart disease evolution, the establishment of the symptoms index system, enrich and develop the theory of traditional Chinese medicine diagnosis and treatment, to play in the biggest advantage of medical treatment of coronary heart disease.2.Questionnaire survey. The use of evidence-based medicine and clinical epidemiology to study cross-sectional survey approach to help check against the dynamic changes of climate observation. Its reliability, validity gifted, able to objectively and comprehensively reflect the signs and symptoms of coronary heart disease.3.Syndrome factor.Frequency distribution analysis showed that coronary heart disease the major elements of spleen yang deficiency syndrome, from early onset to the onset of a sharp increase in frequency, the highest attack, remission and recovery to the overall balance was declined. Decision tree and neural network of the spleen yang deficiency syndrome factors play a key role.4.The symptoms distribution. All the variables in the questionnaire, the frequency distribution of the use of statistical methods, all entries are drawn four times the frequency distribution histograms, and application of medical theory, each variable in each period of dynamic change, the results show :most variables in the pathogenesis of early and higher percentage of attack, especially attack the highest and the degree of weight to the balance of remission and recovery was decreased, lessened, and coronary heart disease (chest pain) and clinical symptoms consistent, for the induction of coronary heart disease syndrome characteristics of evolution of the data provided strong support.
