Abstract

This study aimed to explore the relationship between the serum levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and hypersensitive C-reactive protein (hs-CRP) and the prognosis of acute myocardial infarction (AMI) patients after percutaneous coronary intervention (PCI) treatment. A total of 118 early-onset AMI patients who successfully received PCI (in the PCI group, blood samples were collected before PCI, 12, 24, 48 h after PCI, and 90 d follow-up period) and 52 AMI patients who received only cardioangiography (CAG) (in the CAG group, blood samples were collected before CAG, 12, 24, 48 h after CAG, and 90 d follow-up period). The serum levels of IL-6, hs-CRP and TNF-α were detected, and the incidence of major adverse cardiac events (MACE) in the PCI group during follow-up was observed. The basic levels of IL-6, hs-CRP, and TNF-α between the PCI group and the CAG group were not statistically different (P>0.05); there was no statistically significant difference in changes of serum IL-6, hs-CRP, and TNF-α in the CAG group before and after CAG (P>0.05); IL-6, hs-CRP, and TNF-α in the PCI group were significantly higher than those before treatment (P<0.01); in the PCI group, the levels of IL-6, hs-CRP and TNF-α between the MACE group and the MACE-free group were statistically different (P<0.05). Serum IL-6, hs-CRP and TNF-α levels in AMI patients after PCI significantly increased in the short term, and PCI may induce an inflammatory response; the high levels of inflammatory cytokines, IL-6, hs-CRP, and TNF-α, in peripheral blood may have an important reference value for MACE and short-term prognosis in early-onset AMI patients after PCI.
