several tools, software and algorithms are proposed by the researchers to develop effective medical decision support systems. New software, algorithms and tools are continuously emerging and upgraded depending on the real time situations. Detecting the heart disease is one of the major issues and it is investigated by many researchers. They have developed many intelligent DSS to improve the diagnosis of medical practitioners. Neural network is one among the tools to predict the heart disease. In this research paper, prediction of heart disease using Neural Network is presented. The proposed system used 13 attributes plus 2 additional attributes obesity and smoking for the heart disease prediction. The experiments conducted have shown a good performance.
