Pattern of symptom correlation on type of heart disease using approach of pearson correlation coefficient

Abstract

The relationship of a symptom on a type of disease provides information on how strong the disease is affected by the symptom. The strength of the relationship of symptom has not been much researched, yet it is very interesting and important to do in order to strengthen the formation of final hypothesis, especially in the development of expert system. This research was conducted to map the relationship of a symptom on the type of heart disease, based on the echocardiography value and the result of electrocardiogram measurement. About 150 data of patients with heart disease were analyzed using the approach of Pearson correlation coefficient. The research result showed that the type of disease such as atrial septal defect was much affected by the aorta symptom, the value of left atrium, the ESD, the PR [PQ], and the QRS. The type of coronary artery disease was much affected by the symptom of the values of EDD and ESD. Most of the symptoms did not have a strong relationship for the type of diastolic dysfunction disease. For the type of rheumatic heart disease, about 62.86% symptoms had relationships, spread from the weak relationship, the moderate, the strong, the very strong, and even to the perfect relationship. The type of normal resting echocardiography disease had the relationship level of “no relationship” between the higher symptoms, compared to the rheumatic heart disease; and as well as the types of left ventricular hypertrophy disease and the hypertensive heart disease.
