Severity Classification Based On The Mathematical Model Of The Canadian Angina And Physical And Chemical Indicators, SAQ, SF12

Objective：The data collected by the multi-center, large sample, randomizedcross-sectional survey established Canada angina severity grading judgingmathematical model to clear Canada angina severity grading and physical andchemical indicators of the link between, explore the domestic Canadian anginaseverity grading crowd clinically important physical and chemical indexcharacteristic; attempts to Canada angina severity grading and SAQ SF12mathematical model, clear Canada angina severity grading these scales, exploringCanada angina severity grading and SAQ the SF12’s important entrythe correlationbetween the establishment of the Canadian angina severity grading mathematicalmodel functional..Material and method：Using the series random sampling method, the order of eachhospital patient visits into qualified cases, the sample size is reached. Stableangina pectoris as the research object, using a cross-sectional observationmethod, in12hospitals across the country, gathering the crowd involved in thedifferent regions, the total sample of1800, one-time acquisition meet theinclusion criteria of cases for treatment related information, including theSAQ and SF-12, physical and chemical examination. Through strict quality controland data entry. Correlation coefficient with statistical logistic regressionanalysis of the data.Results: the scale contains two dimensions and seven items. The two dimensionsand the total reliability coefficient are0.833、0.852and0.805respectively;half reliability coefficient are0.727，0.517and0.818respectively; Cronbach’s Alpha coefficients are0.789、0.517and0.814respectively; Factoranalysis extract two male factor whose cumulated variance contribution is54.317%, harmony with structure and theoretical conception hypothesis. The scalehas good reactive degree, meaning it can distinguish between different groupsof patients.Conclusion：The29physical and chemical indicators and SAQ SF12some indicatorswith Canada angina severity grading a strong correlation, the mathematical modelcan reflect Canadian angina severity grading. Evaluation of clinical value needsto be validated analysis, but also need to continue to study and perfect.
