The impact analysis of the oxidative stress injury and inflammatory factor level for ticagrelor assisted PCI in the treatment the elderly patients with ST segment elevation acute myocardial infarction

摘要

Objective:To investigate the effect of ticagrelor assisted PCI in treatment the elderly patients with acute ST elevation myocardial infarction (STEMI) on oxidative stress and inflammatory factor level.Methods:A total of 100 cases elderly patients with STEMI were selected that they were being treated with PCI. According to the digital list method was divided into the study group and control group, and 50 cases in each group. The control group was treated with PCI and the strong heart, anticoagulation, vasodilation, prevention of infection and other comprehensive treatment of myocardial infarction, the study group were given ticagrelor treatment which was based on the comprehensive treatment of myocardial infarction. The level change were compared that oxidative stress index (MDA), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) activity and inflammatory factor hypersensitive C reactive protein (hs-CRP), N-terminal pro brain natriuretic peptide (NT-proBNP) and interleukin -6 (IL-6) between the two groups in before treatment (T0), treatment with 7 d (T1), 14 d (T2), 30 d (T3).Results:(1)There was no significant difference in serum MDA, GSH-Px and SOD levels between the two groups in the T0. Two groups serum MDA level were higher than theT0, and the GSH-Px and SOD levels were lower than the T0 after operation in the T1.And the serum MDA level were lower than T0, T1, GSH-Px and SOD levels were higher than T0, T1in the T2, T3.The T3 serum MDA level was lower than T2, GSH-Px and SOD levels were higher than T2.Even the serum MDA was significantly lower than the control group T1, T2, T3 and the GSH-Px and SOD were higher than those of the control group T1, T2, T3 at the study groupT1, T2, T3, the difference was statistically significant. (2)There was no significant difference in T0 of the serum hs-CRP, IL-6 and NT-proBNP levels between the two groups. Two groups serum hs-CRP, IL-6 and NT-proBNP level were higher than the T0 after operation in the T1.And the serum hs-CRP, IL-6 and NT-proBNP levels were higher than T0, T1in the T2, T3.The T3 serum hs-CRP, IL-6 and NT-proBNP levels were lower than T2.and that the serum hs-CRP, IL-6 and NT-proBNP levels were significantly lower than the control group T1, T2, T3 at the study groupT1, T2, T3, so the difference was statistically significant.Conclusion:The treatment method will be able to reduce oxidative stress injury and effectively control the inflammatory response that ticagrelor assisted PCI in treatment the elderly patients with acute ST elevation myocardial infarction (STEMI).
