Abstract

Heart problems are responsible for the majority of deaths worldwide. The use of intelligent techniques to assist in the identification of existing patterns in these diseases can facilitate treatments and decision making in the field of medicine. This work aims to extract knowledge from a dataset based on heart noise behaviors in order to determine whether heart murmur predilection exists or not in the analyzed patients. A heart murmur can be pathological due to defects in the heart, so the use of an evolving hybrid technique can assist in detecting this comorbidity team, and at the same time, extract knowledge through fuzzy linguistic rules, facilitating the understanding of the nature of the evaluated data. Heart disease detection tests were performed to compare the proposed hybrid model’s performance with state of the art for the subject. The results obtained (90.75% accuracy) prove that in addition to great assertiveness in detecting heart murmurs, the evolving hybrid model could be concomitant with the extraction of knowledge from data submitted to an intelligent approach.

A heart murmur is a comorbidity related to blood flow passage through the heart, generating sounds that can identify a circulatory problem regarding the heart’s functions. They can be identified in both children and adults, but for the most part, they can be just innocent murmurs with no other changes and with absolutely normal physical development. Another form of this heart murmur is due to complications of heart diseases that generally occurred in childhood, and care must be taken on the part of doctors so that the treatment to be carried out is appropriate for the maintenance of a healthy life on the patient’s part [3]

Summary

Introduction

Society seeks to work on solutions that reduce the negative impacts of groups of diseases on human beings routinely. Among these diseases, those that attack the heart stand out, and may decrease the standard of living when playing sports or daily activities, and even cause death [1].
