Objective: Quality of life and mental well-being are some of the issues that can play an important role in the disease and its treatment. The purpose of this study was to compare the quality of life and mental well-being of myocardial infarction patients and healthy people. Methods: This is a causal-comparative study with parallel groups. The statistical population of this study was all myocardial infarction patients in Sina hospital in Tehran in 2019. To select sample of the study, 69 myocardial infarction patients and 72 healthy people were selected through available sampling method. Data were collected by the use of the Quality of Life Questionnaire (QoL, SF-36) and Psychological Wellbeing Scale (PWB). Then, the collected data were analyzed by descriptive statistical methods, Mann-Whitney U test, and one-way variance analysis (ANOVA). Results: In terms of quality of life, healthy people were at a higher level compared to patients (F=49.90, P<0.05), but the score of total quality of life regarding the sex difference was not significant in healthy and patient groups (F=1.74, P>0.05). Also, the dimensions of mental well-being were higher in healthy subjects than in myocardial infarction patients (F=4.41, P<0.05) and there was no difference between male and female (F=0.01, P>0.05). Conclusion: Myocardial infarction patients have a lower quality of life and subjective well-being than healthy people. Based on the results, it is necessary to pay more attention to two variables of quality of life and subjective well-being in the design of interventions to reduce the psychological problems of patients with MI.
