Effect of tirofiban intracoronary drugs on myocardial perfusion in patients with acute st-segment elevation myocardial infarction during emergency PCI

Objective To analyze the effect of different intracoronary drugs on myocardial perfusion in patients with acute ST-segment elevation myocardial infarction after emergency PCI.Methods Totally 120 patients with acute ST-segment elevation myocardial infarction admitted to the Affiliated Hospital of Xuzhou Medical University in recent two years were selected and randomly divided into two groups. The study group was treated with emergency PCI combined with tirofiban intracoronary medication, while the control group was treated with emergency PCI combined with urokinase intracoronary medication; the indexes of myocardial reperfusion and cardiac function were measured after treatment. Cardiovascular accidents were monitored and the differences between groups were statistically analyzed.Result The peak time of CK-MB and CK-MB in the study group were significantly lower than those in the control group, and the NO level in the study group was significantly better than that in the control group, with significant difference between the two groups (P < 0.05). TIMI blood flow staging in the study group was significantly better than that in the control group, with significant difference between the two groups (P < 0.05). The reduction of ST segment in the study group was significantly better than that in the control group, with significant difference between the two groups (P < 0.05). LVEF, LVEDV, and LVESV in the study group were significantly better than those in the control group (P < 0.05). The levels of sICAM-1, sVCAM-1, vWF and hs CRP in the study group were lower than those in the control group (P < 0.05). The incidence of cardiovascular adverse events at 30 days after surgery was lower in the study group than in the control group (P < 0.05).Conclusion Compared with the traditional emergency PCI alone, tirofiban as an intracoronary drug in emergency PCI can improve the effect of cardiac perfusion, improve the cardiac function score, and reduce the occurrence of cardiovascular adverse events. Its safety and stability are better, and ultimately improve the clinical effect and prognosis. It is suggested that further large-sample study and clinical promotion should be carried out.
