In this paper the focus is on using different algorithms and combinations of several target
attributes for effective heart attack prediction using data mining. Decision Tree has outperformed
with 99.62% accuracy by using 15 attributes. Also the accuracy of the Decision Tree and
Bayesian Classification further improves after applying genetic algorithm to reduce the actual
data size to get the optimal subset of attribute sufficient for heart disease prediction.
Association classification technique apriori algorithm, was along with a new algorithm MAFIA
was used .
Straight Apriori-based algorithms count all of the 2k subsets of each k-item set they discover, and
thus do not scale for long item sets. They use “look a heads” to reduce the number of item sets to
be counted. MAFIA is an improvement when the item sets in the database are very long.
