Abstract Heart disease is a fatal human disease that rapidly increases globally in developed and underdeveloped countries and causes death. This disease's timely and accurate diagnosis is essential for avoiding patient harm and preserving their lives. This study compared the classifier’s performance in three stages: complete attributes, class balance, and after-feature selection. For class balancing using SMOTE (Synthetic Minority Oversampling Technique) and Elastic Net feature selection algorithm has been used to select suitable features from the available dataset. In this study, justification of performance, the authors have used Logistic Regression (LR), K-nearest neighbor (KNN), Support vector machine (SVM), Random Forest (RF), Adaboost (AB), Artificial neural network (ANN), and Multilayer perceptron (MLP). It has been found that the performance increased ANN and LR after class balance and was unchanged in SVM and MLP. The classification accuracies of the top two classification algorithms, i.e., RF and Adaboost, on full features were 99% and 94%, respectively. After applying feature selection algorithms, the classification accuracy of RF slightly decreases from 99% to 92%. The accuracy of Adaboost decreases from 94% to 83%. However, the performance of classifiers increased after class balance and feature selection, such as KNN, SVM, and MLP. After class balancing and feature selection, we observed that the SVM classifier performs best.
