Methods: In this study, 105 patients with heart failure were selected. They were admitted to the cardiac ICU in educational hospitals in Tehran. Data collection tools were demographic information, heart failure health literacy, and quality of life questionnaires. Descriptive statistics and statistical methods of correlation and regression were performed using SPSS v. 24. Results: The results showed a significant positive relationship (r= 0.40) between health literacy and quality of life scores in patients with heart failure. Also, health literacy significantly predicted the quality of life score in patients with heart failure (P<0.001). The results of bivariate regression analysis showed that health literacy scores significantly predict the quality of life of patients with heart failure (P<0.001, r2= 0.16). Conclusion: The findings showed that health literacy could predict the quality of life in patients with heart failure. So, it is crucial to consider health literacy in health promotion programs and improve the quality of life of these patients.
