Abstract

Introduction. The quality of life depends on physical, psychological and social factors that are evidently influenced by the individual’s actions, prospect, attitude and behavior. Heart disease is one of the most imperative health problems in the world. Studies showed that exercise-based rehabilitation for patients with coronary artery disease effectively lowers the rate of cardiac death. The intent of this study was to determine the effects of physical activity on the life quality of cardiovascular patients after coronary artery bypass graft.

Materials and Methods. This randomized clinical trial was performed on two groups of coronary artery patients of Yazd Afshar hospital. All the 70 participants were post surgery coronary artery patients who were divided into two groups. Data was collected by two questionnaires: A personal information questionnaire and a quality of life questionnaire (SF=36). Data of both groups was collected in the first and fourth month after the discharge from surgery and sessions were analyzed by SPSS 16 and by using T-test and Chi-square.

Results. Results displayed that after the intervention, all the categories of the components of the quality of life were increased except for general health. There was no significant differentiation between these statuses in the control group and the premier grades about the components of the social function (88.98 out of 100). The comparison of total scores of the quality of life before the intervention showed the quality of life of both groups one month after surgery was not significant (p=75%), but in four months after surgery, the distinction between the mean grade scores of the intervention, the group was considerable (p=0.0001).

Conclusion. The comparison of the total scores of the quality of life indicated an increase in the scores of the quality of life in the intervention group after the exercise.
