Data mining has been successfully used in numerous businesses and sectors as a result of its success in great visible areas like e-commerce and marketing. Healthcare is one of the recently identified industries. The healthcare sector continues to be "information-rich." Healthcare systems have access to a multitude of datasets and can use them to find hidden links and trends in data. There aren't enough efficient analysis tools, though. The dataset is analyzed using various machine learning algorithms, i.e., decision trees, neural networks, support vector machines, and algorithms. The experiment makes use of data mining. This study paper aims to present an overview of the most recent methods for knowledge discovery in databases utilizing. Data mining is a technique used in modern medical research, especially to predict heart disease. The primary cause of a significant portion of deaths worldwide is heart disease. Several experiments on the dataset have been done to compare the performance of predictive data mining techniques. The results show that SVM performs better of Other predictive techniques, such as ANN Neural Networks, and the decision tree performs poorly. We are recommending that you test more classifiers, so you may compare the results with other algorithms and improve the system in our earlier work by adding more features. This will help the system predict and diagnose people with heart disease more accurately. Povzetek: Glavni cilj te študije je bil napovedati človeško stanje in ali ima srčno bolezen ali ne.

The stored data can be useful for the source of predicting the occurrence of future disease. Some of the data mining and machine learning techniques are used to predict heart disease, such as Artificial Neural Network (ANN), Decision tree, K-Nearest Neighbor(KNN), Naive Bayes and Support Vector Machine (SVM). This paper provides an insight into the existing algorithm and it gives an overall summary of the existing work.

Review of Heart Disease Prediction using Data Mining Techniques

Health care data includes patient centric data, their treatment data and resource management data. It is very massive and information rich. Data mining techniques have been used in healthcare research and known to be effective. The Healthcare industry is generally " information rich " , which is not feasible to handle manually. These large amounts of data are very important in the field of Data Mining to extract useful information and generate relationships amongst the attributes. The doctors and experts available are not in proportion with the population. Also, symptoms often be neglected. Heart disease diagnosis is a complex task which requires much experience and knowledge. Heart disease is a single largest cause of death in developed countries and one of the main contributors to disease burden in developing countries. In the health care industry the data mining is mainly used for predicting the diseases from the datasets. The Data Mining techniques, namely SVM, Ensemble Classifier methods, Decision Trees, Naive Bayes, Neural Networks and Genetic Algorithm are analyzed on Heart disease database.

Data Mining in Healthcare for Heart Diseases

Data Mining is the area of research which means digging of useful information or knowledge from previous data. There are different techniques used for the data mining. Data mining may used in different fields including Healthcare. Heart or Cardiovascular diseases are the very hot issue in Healthcare industry globally. Many patients died due to insufficient amount of knowledge. As Healthcare industry produces a huge amount of data, we may use data mining to find hidden patterns and interesting knowledge that may help in effective and efficient decision making. Data mining in Healthcare is a crucial and complicated task that needs to be executed accurately. It attempts to solve real world health problems in diagnosis and treatment of diseases.

A Comparative Study for Predicting Heart Diseases Using Data Mining Classification Methods

Improving the precision of heart diseases detection has been investigated by many researchers in the literature. Such improvement induced by the overwhelming health care expenditures and erroneous diagnosis. As a result, various methodologies have been proposed to analyze the disease factors aiming to decrease the physicians practice variation and reduce medical costs and errors. In this paper, our main motivation is to develop an effective intelligent medical decision support system based on data mining techniques. In this context, five data mining classifying algorithms, with large datasets, have been utilized to assess and analyze the risk factors statistically related to heart diseases in order to compare the performance of the implemented classifiers (e.g., Naïve Bayes, Decision Tree, Discriminant, Random Forest, and Support Vector Machine). To underscore the practical viability of our approach, the selected classifiers have been implemented using MATLAB tool with two datasets. Results of the conducted experiments showed that all classification algorithms are predictive and can give relatively correct answer. However, the decision tree outperforms other classifiers with an accuracy rate of 99.0% followed by Random forest. That is the case because both of them have relatively same mechanism but the Random forest can build ensemble of decision tree. Although ensemble learning has been proved to produce superior results, but in our case the decision tree has outperformed its ensemble version.
