Abstract: Heart diseases are one of the main causes of death around the world. The most reliable method for heart disease diagnosis is angiography, which is costly, invasive and has the risk of death. This study applies variations of decision tree (DT), support vector machine (SVM) and voting algorithms to construct a heart disease diagnosis predictive model. We show that integrating medical knowledge and statistical knowledge as well as fine tuning the parameters of the used models lead to more effective heart disease diagnosis models. We use two methods for implementing the proposed model. The obtained results in both methods show that voting algorithm and random forest outperform other methods. Moreover, the achieved accuracies show improvements over other existing methods.
