摘要：The goal of this study is to recognize most important risk factors associated with surgical mortality in patient who underwent CABG by the integration of fuzzy concept and analytical hierarchy process method to represent pairwise comparison of odd ratios and overcome ambiguities involved in the statistical data. A literature search from 1980 to January 2013 using the MEDLINE and Science Direct database is performed and data of the reported predictors were extracted. A fuzzy AHP model for comparing the relative importance of risk factors was developed. Moreover, fuzzy clustering method is applied to classify calculated weight of risk factors. The result indicated that advanced age (over 70 years), sever left ventricular ejection fraction (LVEF
