TNF and congestive heart failure: The results of this study showed that serum SUA, IL-6 and TNF-α levels were higher in the CHF group than in the healthy control group, suggesting a state of high SUA levels and high inflammatory factor levels in CHF patients, and the study showed that SUA, IL-6 and TNF-α levels were higher in patients with poor prognosis CHF than in patients with good prognosis CHF, similar in part to previous studies [11], suggesting the involvement of SUA and inflammatory responses in the development of CHF disease may be related to their prognosis after CHF revascularization.
