Diagnosis of some Diseases in Medicine via Computerized Experts System

Nowadays medical application especially diagnosis of some heart diseases has been rapidly increased because its importance and effectiveness to detect diseases and classify patients. In this research, we present the design of an expert system that aims to provide the patient with background for suitable diagnosis and treatment (Especially Angina Pectoris and Myocardial infarction). The proposed methodology is composed of four stages. The first stage is receiving the symptoms from the patient. The second stage is requesting from the patient to make some analysis and investigation to help the system to make a correct decision in the diagnosis. The third stage is doing diagnosis of patient according to information from patient (symptoms, analysis and investigation). The four stage is determining the name of appropriate medication or what should be done until the patient recovers (step therapy), so this system is able to give appropriate diagnosis and treatment for two heart diseases namely; angina pectoris and infarction. There are several programs used for diagnosis and system analysis, such as CLIPS and PROLOG. A medical expert system in this search made by Visual Prolog 7.3 is proposed.
