Coronary Heart Disease (stable Angina) Syndrome Elements Syndrome Characteristics And Pathogenesis Of Syndrome Evolution Law Of The Clinical Expert Questionnaire Development And Preliminary Testing

Objective:We design the questionnaire of syndrome elements ,syndrome characteristics and evolution of disease syndromes of coronary heart disease (stable angina) to clinical experts, and do a preliminary test for the future study of coronary heart disease Syndrome Distribution of reference.Methods:According to the standards has been promulgated by the state,we access to a large number of ancient and modern literature, expert advices, psychological measurements from modern theories of structure and the introduction of the decision-making to sum up the evidence of coronary heart disease designate characteristics of evolution.It will be shown by the characteristics of the symptoms of coronary heart disease as the on the subject of the establishment of symptoms index system, as conceived and designed coronary heart disease (stable angina) Syndrome elements syndrome characteristics and evolution of disease syndromes of clinical experts to the questionnaire. Inventory of all entries in terms of the content and expression of the accuracy of the validation and, based on this, the repeated use of the Delphi method to amend entries, deletions, adjustment process, thereby ensuring the entries and content of the questionnaire responses can be accurate coronary heart disease in clinical symptoms and signs, and ultimately determine the characteristics of coronary heart disease Syndrome clinical experts and the evolution of the basic framework of the questionnaire and content. And through 300 front-line clinical investigations of cardiovascular experts, the scale of reliability, validity of the evaluation.Results:The questionnaire of coronary heart disease described attendance data through four phases, and are on the scale of the module table and the total reliability and validity of the test. Cronbach'sαfactor: 0.9593～0.9725 between the various modules are greater than 0.8, the survey of the Cronbach'sαvalue is 0.9903. And a half letter: all modules in between 0.8918～0.9225, the total scale reliability and a half Cronbach'sαof value is 0.9207. Factor analysis showed that: each module separately from the four factors in the total contribution rate of more than 40%, the largest variance by the rotation concept consistent with the theoretical results.Conclusion:The clinical experts survey of syndrome elements, syndrome characteristics and evolution of disease syndromes of coronary heart disease (stable angina) has good reliability and validity.It can response to patients with coronary artery disease symptoms and signs comprehensively. We can study the syndromes of coronary heart disease by using it.
