The Healthcare industry is generally “information rich”, but
unfortunately not all the data are mined which is required for
discovering hidden patterns & effective decision making.
Advanced data mining techniques are used to discover
knowledge in database and for medical research, particularly
in Heart disease prediction. This paper has analysed prediction
systems for Heart disease using more number of input
attributes. The system uses medical terms such as sex, blood
pressure, cholesterol like 13 attributes to predict the likelihood
of patient getting a Heart disease. Until now, 13 attributes are
used for prediction. This research paper added two more
attributes i.e. obesity and smoking. The data mining
classification techniques, namely Decision Trees, Naive
Bayes, and Neural Networks are analyzed on Heart disease
database. The performance of these techniques is compared,
based on accuracy. As per our results accuracy of Neural
Networks, Decision Trees, and Naive Bayes are 100%,
99.62%, and 90.74% respectively. Our analysis shows that out
of these three classification models Neural Networks predicts
Heart disease with highest accuracy.
