Objective:To investigate the effect of PCI on inflammatory factors, cTnI, MMP-9and NT-pro BNP in patients with unstable angina pectoris.Methods:A total of 80 unstable angina pectoris patients were divided into observation group (40 cases) and control group (40 cases). The observation group was given the therapy of PCI, and the control group was given coronary angiography. To observe the of inflammatory factors, cTnI, MMP-9 and NT-pro BNP were tested and compared before and after operation.Results:At 24 h after operation, CRP and IL-18 levels were increased significantly after treatment inoperation groups, there was no difference on inflammatory factors in control group, and had significant difference on inflammatory factors in two groups; At 24 h after operation, cTnI, MMP-9 and NT-pro BNP levels were increased significantly after treatment inoperation groups, there was no difference on inflammatory factors in control group, and had significant difference on inflammatory factors in two groups.Conclusion: PCI therapy can induce inflammation and myocardial injury in patients with unstable angina pectoris.
