Heart disease is a deadly disease in human life. The mortality rate from any disease is the highest in the world. Therefore, before reaching the final stage of this heart disease, all precautionary measures must be taken. For this reason without the help of any kind of traditional methods, if we can scientifically diagnose heart disease at an early stage through various decision support systems, then surely death rate of this disease will decrease in the whole world. Many researchers investigate the diagnosis of heart disease by creating various intelligent medical decision support systems. Artificial neural network concepts represent the highest predictive accuracy over medical data compared to other decision support systems.
In this paper we propose a better prediction method for the existence of heart disease through the scaled conjugate gradient back propagation of artificial neural networks using K-fold cross validation. For cardiac datasets, the University of California Irvine (UCI) Machine Learning Repository and IEEE data port have been used. For Cleveland processed heart dataset, the proposed system uses 13 input attributes and provides minimum 63.3803% & maximum 100% accurate results similarly for Cleveland Hungarian Statlog heart dataset the proposed system uses 11 input attributes and provides minimum 88.4754% & maximum 100% accurate results by estimating the presence and absence of heart disease during testing.
