Abstract EN
Heart failure (HF) is considered a deadliest disease worldwide.
Therefore, different intelligent medical decision support systems have been widely proposed for detection of HF in literature.
However, low rate of accuracies achieved on the HF data is a major problem in these decision support systems.
To improve the prediction accuracy, we have developed a feature-driven decision support system consisting of two main stages.
In the first stage, χ2 statistical model is used to rank the commonly used 13 HF features.
Based on the χ2 test score, an optimal subset of features is searched using forward best-first search strategy.
In the second stage, Gaussian Naive Bayes (GNB) classifier is used as a predictive model.
The performance of the newly proposed method (χ2-GNB) is evaluated by using an online heart disease database of 297 subjects.
Experimental results show that our proposed method could achieve a prediction accuracy of 93.33%.
The developed method (i.e., χ2-GNB) improves the HF prediction performance of GNB model by 3.33%.
Moreover, the newly proposed method also shows better performance than the available methods in literature that achieved accuracies in the range of 57.85–92.22%.
