AIMS:To determine the contributions of different kinds of symptoms to the quality of life and mediating effect of psychological and physical symptoms between heart failure symptoms and quality of life.DESIGN:A multi-centre cross-sectional study.METHODS:2006 chronic heart failure patients from four cities were recruited in China from January 2021 to December 2022. Patients' symptoms and quality of life were self-reported, and data were analysed using correlation analysis, dominance analysis and mediating effects analysis.RESULTS:The dominance analysis revealed that the overall mean contributions of heart failure, psychological and physical symptoms were .083, .085 and .111; 29.5%, 30.2% and 39.5% of the known variance. And heart failure symptoms could negatively affect quality of life through psychological and physical symptoms, accounting for 28.39% and 22.95% of the total effect. Heart failure symptoms could also affect quality of life through the chain-mediated effect of physical and psychological symptoms, accounting for 16.74%.CONCLUSIONS:Physiological symptoms had the strongest effect on quality of life and heart failure symptoms had the weakest. Most of the effect for heart failure symptoms on quality of life in chronic heart failure patients was mediated by psychological and physiological symptoms.RELEVANCE TO CLINICAL PRACTICE:It is important to design non-pharmacological intervention plans for the enhancement of physical and psychological symptoms' management skills, to reduce the adverse impact of heart failure symptoms on quality of life.REPORTING METHOD:Study methods and results reported in adherence to the STROBE checklist.NO PATIENT OR PUBLIC CONTRIBUTION:No patients or members of the public were involved in the study.

PURPOSE:Despite advances in treatment and management, Chronic heart failure (CHF) is still associated with poor prognosis, a high rate of hospitalization and readmission, and reduced quality of life (QOL). However, the relationship between QOL and health literacy in patients with CHF remains unclear. This study aimed to examine the association between health literacy and QOL, among Chinese patients with CHF.METHOD:This is a cross-sectional study of a convenience sample from a cardiovascular hospital in Henan Province in China. Subjects completed a self-administered questionnaire that assessed the heart failure-specific health literacy score. QOL was measured using the Minnesota Living with heart failure scale. Unadjusted and adjusted multiple linear regression were used to explore the association between health literacy and QOL.RESULTS:This study sampled 299 patients, with a mean age of 61.9 ± 14.9 years old. The association between health literacy and QOL was significant only in the unadjusted model (P < 0.001) and was no longer statistically significant after controlling for covariates. The final best-fitted model identified 9 significant predictors, accounting for 38.6% of the variance in quality of life.CONCLUSIONS:This study suggests that there is no relationship between health literacy and QOL in Chinese CHF patients after adjusting for covariates. Residence, monthly income, self-care management, self-efficacy and social support are significantly associated with QOL. Compared patients with high health literacy, patients with low health literacy may have problems comprehending healthcare information and following disease management instructions, which might contribute to diminished QOL. Therefore, in clinical practice, effective interventions such as creating appropriate materials for low-literacy patients and performing education to raise self-care management, self-efficacy, might improve the QOL of patients with CHF.
