Abstract
In this article we studied relationship between physical and mental factors on the quality of life in patients with coronary vascular disease. This study is an analytic simulation based on Fuzzy linear regression model .Statistical population was all the patients who were admitted/monitored and controlled in Dr.Shariati Hospital for vascular coronary disease. The method of data collection was survey by questionnaire. The two subgroups of experimental and control group were allocated through random sampling. As for the number of samples ,we obeyed similar previous studies in this field ,the samples number was determined by the formula of sampling frame on the Quasi-experimental studies in Althman Normogram scale. In order to perform analytical linear Fuzzy regression in the research to study the effective factors on the quality of life(life style) among coronary vascular patients ,the independent variables were: age , mass body index, blood fat index, blood pressure, and the level of stress .The dependent variable was (patients life style).The results of the data analysis by fuzzy linear regression indicated that the impact of body mass index, blood fat ,blood pressure, as well as the anxiety level of the patient had decreasing effects on the coronary arterial patients life style.
