BackgroundIt has been generally agreed that cardiac failure is one of the common and devastating diseases due to its morbidity, mortality and rates of disability. Moreover, it has negative impacts on quality of life among sufferers. Meanwhile, improving quality of life among heart failure patients is essential. It can be suggested that people with self-care ability have a better quality of life. However, this issue may be affected by some cultural issues. Regarding a paucity of information on this aspect in Iran, this study aims to explore the relationship between self-care behaviors and quality of life in patients with heart failure.MethodsThis study is carried out using a descriptive - analytical method. The sample size consists of 77 patients who consented to participate in the study and had ejection fraction <40%. The tools were demographic checklist, European heart failure self-care behavior scale, and SF-36 quality of life questionnaire. Data was gathered from the heart center of Imam Ali in Kermanshah-Iran. Data analysis was done using independent t-test, Mann Whitney, ANOVA, and Kruskal-Wallis tests by SPSS-24 software.FindingsThe study sample was 77 participants, of which 45 were female and 51 lived in an urban area. The mean of self-care score was 39.42 ± 7.04, and most of the patients (67.5%) were in moderate level. The mean and SD of quality of life was estimated as 38.45 ± 17.28. The spearman correlation test showed no correlation between self-care and quality of life. However there was a correlation between marital status and self-care ability, in which it shows the higher scores in unmarried people (K2 = 7.75, P = 0.021), and the results indicated better quality of life in male (t = 2.68, P = 0.009), educated patients at the level of university (F = 7.60, P < 0.001), free job (F = 6.21, P < 0.001) and lived in the urban area (Z = 2.05, P = 0.04).ConclusionIn this study, there is no correlation between self-care behaviors and quality of life in which, this may be attributed to Iranian cultures and perspectives such as valuing live with the children and importance of their attention to elderly patients, which demanded more studies.
