Abstract:Objective: To investigate the expression and prognostic value of caveolin-3 and Toll-like receptor 4 (TLR4) in the serum of elderly patients with heart failure (HF) complicated by arrhythmia. Methods: A total of 96 patients with heart failure complicated by arrhythmia admitted to our hospital from June 2022 to June 2023 were included as the study group, and 98 patients without heart failure complicated by arrhythmia were included as the control group. Adverse cardiovascular events that occurred during the 12-month follow-up period were recorded, and the patients were assigned to a poor prognosis group (n=33) and a good prognosis group (n=63) based on the results. Enzyme linked immunosorbent assay was applied to detect the expression levels of Caveolin-3 and TLR4 in serum. Multivariate logistic regression was applied to analyze the factors affecting the prognosis of patients with heart failure complicated by arrhythmia. The receiver operating characteristic (ROC) curve was plotted to analyze the predictive value of Caveolin-3 and TLR4 levels for poor prognosis in patients with heart failure complicated by arrhythmia. Results: Compared with the control group, the serum TLR4 level was higher and Caveolin-3 level was lower in the study group (t=8.393, 10.228, all P<0.05). The difference in cardiac function grading between the poor prognosis group and the good prognosis group was statistically obvious (χ2=35.024, P<0.05). The serum TLR4 level in the poor prognosis group was higher than that in the good prognosis group, while the Caveolin-3 and LVEF levels were lower than those in the good prognosis group (t=6.510, 7.280, 3.816, all P<0.05). Multivariate logistic regression analysis showed that cardiac function grading and TLR4 level were risk factors for poor prognosis, while LVEF and Caveolin-3 levels were protective factors for poor prognosis (P<0.05). ROC curve showed that the AUC of predicting poor prognosis in patients with heart failure complicated by arrhythmia by serum Caveolin-3 and TLR4 levels was 0.775 and 0.854, respectively. The AUC predicted by the combination of the two was 0.898, higher than that of single indicator detection (Z=2.964, P=0.003, Z=2.111, P=0.035). Conclusion: The serum level of Caveolin-3 is decreased and TLR4 is increased in patients with heart failure complicated by arrhythmia. The combined detection of the two can be used as serum markers to evaluate the poor prognosis of patients with heart failure complicated by arrhythmia.
