The health-related quality of life (HRQoL) of patients with heart failure (HF) in rural settings in China remains unclear. Limited studies explored the mediating effect of uncertainty in illness between heart failure symptoms and HRQoL in this population. To explore the status of HRQoL in rural patients with HF; assess the impact of HF symptoms and uncertainty in illness on HRQoL; and examine the mediating effect of uncertainty in illness on the relationship between symptoms and HRQoL in rural patients with HF. Overall, 298 rural patients with HF were recruited from five township hospitals of Taishan and Jinzhong City in China between November 2021 and August 2022. Three variables, namely HF symptoms, uncertainty in illness, and HRQoL were measured using three validated scales. The average score of HRQoL in rural patients with HF was 43.19. Of the participants, 60.4 %, 35.23 %, and 4.37 % exhibited poor, moderate, and good HRQoL, respectively. The HF symptoms ( = −0.47) and uncertainty in illness ( = −0.34) directly influenced HRQoL. Moreover, the HF symptoms also indirectly affected HRQoL through uncertainty in illness ( = −0.07). The indirect effect accounted for 12.96 % of the total effect of HF symptoms on HRQoL. Rural patients with HF exhibited poor HRQoL. In this population, HF symptoms and uncertainty in illness were negatively associated with HRQoL. Uncertainty in illness mediated the relationship between HF symptoms and HRQoL. Tailored healthcare services should be developed for the rural population to alleviate HF symptoms, reduce uncertainty in illness, and enhance their HRQoL.
