Design of a fuzzy expert system for determination of coronary heart disease risk

The aim of this study is to design a Fuzzy Expert System to determine coronary heart disease (CHD) risk of patient for the next ten-years. The designed system gives the user the ratio of the risk and may recommend using one of three results; (1) normal live; (2) diet; (3) drug treatment. The data (risk ratio) obtained from designed system are compared with the data in the literature [4] and better results are observed in the designed system. The system can be viewed as an alternative for existing methods to determine CHD risk.
