Abstract:
Objective To investigate the correlation of postoperative cytokine levels with infarct size and reperfusion injury in acute myocardial infarction(AMI)patients having achieved success-ful recanalization after PCI.Methods Clinical data of 164 AMI patients who underwent successful PCI in our department between March 2022 and March 2024 were collected and retrospectively analyzed.The levels of IL-6 and TNF-α were measured at 1 d after PCI,and base on the cutoff level,the patients were categorized into a high IL-6 group(≥5.72 ng/L,93 cases)and a low IL-6 group(<5.72 ng/L,71 cases),and also into a high TNF-α group(≥5.27 ng/L,108 cases)and a low TNF-α group(<5.27 ng/L,56 cases).General information,infarct volume and reperfusion injury were compared between the groups.Multivariate logistic regression analysis was used to identify the influencing factors of IL-6 and TNF-α.Pearson correlation analysis was employed to assess the correlation of IL-6/TNF-α levels with infarct size,while Spearman correlation analysis was utilized to evaluate their correlation with reperfusion injury.ROC curves were plotted to de-termine the predictive value of the two cytokines for reperfusion injury.Results The high IL-6 group showed significantly higher ratio of diabetes,larger proportion of reperfusion injury,greater infarct size,increased cardiac troponin I(cTnI)level,and longer PCI time than the low IL-6 group(P<0.01),and similar results were seen in the high TNF-α group when compared with the low TNF-α group(P<0.01).Multivariate logistic regression analysis identified PCI time(OR=3.492,95%CI:2.253-5.411),cTnI(OR=5.126,95%CI:1.104-23.787),infarct size(OR=1.178,95%CI:1.026-1.352),and reperfusion injury(OR=3.283,95%CI:1.099-9.809)as independent risk factors for elevated IL-6,while PCI time(OR=3.101,95%CI:2.027-4.742),cTnI(OR=3.498,95%CI:1.730-7.072),infarct size(OR=1.234,95%CI:1.051-1.449),and reperfusion injury(OR=3.518,95%CI:1.017-12.170)as independent risk factors for increased TNF-α.Pear-son and Spearman analysis showed that the IL-6 and TNF-α levels were positively correlated with infarct volume and reperfusion injury(P<0.01).ROC curve analysis indicated that the AUC value of IL-6 and TNF-α in predicting reperfusion injury was 0.693(95%CI:0.616-0.762)and 0.681(95%CI:0.604-0.752),with a sensitivity of 60.49%and 81.25%,and a specificity of 71.08%and 78.81%,respectively.Conclusion In AMI patients after PCI recanalization,elevated IL-6 and TNF-α levels are positively correlated with infarct size and reperfusion injury,and the levels can serve as biomarkers for assessing the occurrence of reperfusion injury.
