Objective: Describe the change of quality of life among patients with heart failure after health education at Quang Ninh General Hospital in 2023. Methods: Research on health education intervention with before and after comparison on 74 patients with heart failure from March to August 2023. Results: The mean score about impact of heart failure on overall, physical and mental health was 79.3 ± 0.1, 30.6 ± 4.6 and 23.1 ± 2.2. After one month of intervention, the mean score decreased to 62.2 ± 9.17
24.2 ± 3.9 and 17.2 ± 2.4 (p<
0.001). After two months of intervention, the mean score continued reducing to 47.1 ± 8.9
18.5 ± 3.7
12.6 ± 2.6 (p<
0.001). Patients’ status of sleep difficulty, poor appetite, and thoughts of being their family’s burden were improved after the intervention. Conclusion: Hospitals should come up with a specific intervention program to improve this status for patients with heart failure, especially psychological counseling for patients to help them feel more comfortable, eat better, and sleep well.
