Effect of thrombolysis with recombinant human TNK tissue plasminogen activator for injection in the treatment of acute ST-segment elevation myocardial infarction

Objective To discuss the effect of thrombolysis with recombinant human TNK tissue plasminogen activator(rhTNK-tPA)for injection in the treatment of acute ST-segment elevation myocardial infarction.Methods A total of 32 patients with acute ST-segment elevation myocardial infarction were studied and divided into reference group and research group according to different treatment methods,with 16 cases in each group.The control group was treated with urokinase,and the research group was treated with rhTNKtPA.The coronary angiography results of patients with coronary angiography at 90 min after thrombolytic therapy,incidence of endpoint events after thrombolytic therapy,and revascularization rate of patients without coronary angiography at 90 min after thrombolytic therapy were compared between the two groups.Results The recanalization rates of infarct-related vessels(IRA)thrombolysis in myocardial infarction(TIMI)grade 3 and IRA TIMI grade 2-3 in the research group were 83.33%and 91.67%in patients undergoing coronary angiography at 90 min after thrombolytic therapy,which were higher than 38.46%and 46.15%in the reference group,and the difference was statistically significant(P<0.05).There was no statistically significant difference in the incidences of death(within 30 d),target vessel reconstruction,myocardial ischemia recurrence,cardiogenic shock,reinfarction,and other complications between the two groups after thrombolytic therapy(P>0.05).There was no statistically significant difference in the revascularization rate between the two groups of patients without coronary angiography at 90 min after thrombolytic therapy(P>0.05).Conclusion The application of rhTNK-tPA in patients with acute ST-segment elevation myocardial infarction can improve the recanalization rate of coronary angiography with certain safety.
