There are conditions that increase an individual's risk of having a poor prognosis if infected with the COVID-19 virus, including heart disease. This condition can cause anxiety in heart failure patients and reduce the body's resistance. This study aims to identify the effect of guided imagery and health education on the anxiety of heart failure patients during the COVID 19 pandemic. The study used a Quasi Experiment. The number of samples was 62 respondents, given guided imagery relaxation and health education through booklets for 14 days. Statistical tests used Wilcoxon test and Ordinal Logistic Regression. The results showed that the level of anxiety before the intervention 61.3% moderate anxiety level and after the intervention 83.9% were not anxious. There was a significant effect between guided imagery and health education with anxiety levels (0.000). In conclusion, guided imagery relaxation and health education have an effect on decreasing the anxiety level of heart failure patients. This study recommends the need for further research on other therapies as nurse interventions in heart failure nursing care.  Key words: Anxiety; COVID-19; health education; heart failure; guided imagery
