Significance was considered 0.05. Results: The results showed that the mean±sd of physical activity was 2.59‌±1.33 and the mean±sd of fatigue in the samples was 20.27±6.11 and the majority of patients had below normal physical activity and fatigue was unfavorable in the majority of them. The total score of physical activity was inversely and significantly correlated with the total score of fatigue. The results showed that 30.6% of the changes in patients ‘fatigue were influenced by variables of drug use, history of heart surgery and the degree of disease and they were predictors of patients’ fatigue.
