Effects of prourokinase,reteplase and urokinase on the patients with acute ST -segment elvation myocardial infarction / 中国基层医药

ABSTRACT

Objective To compare the efficacy and safety of prourokinase,reteplase and urokinase on the patients with acute ST -segment elvation myocardial infarction.Methods According to random number table,the eligible patients with acute ST -segment elvation myocardial infarction were randomly divided into prourokinase group (50mg,n =34),reteplase group (36mg,n =42)and urokinase group (1 500 000IU,n =32).The patency of infarct related coronary artery was estimated by coronary angiography at 90min after administration of thrombolytic agents.The adverse reaction was also observed including bleeding and the major adverse cardiac events(MACEs).Results The patency of culprit vessel in the prourokinase group was 76.50% (≥TIMI 2 flow),which in the reteplase group was 83.30% (≥TIMI 2 flow),and which in the urokinase group was 53.10% (≥TIMI 2 flow),respctively.Both of prourokinase group and reteplase group were higher in the patency than theurokinase group(χ2 =8.27,P =0.004). The MACEs and bleeding adverse reaction(prourokinase group 17.65%,reteplase group 28.57%,urokinase group 42.19%)showed that security of prourokinase group was securer than reteplase group and urokinase group(χ2 =6.36,P =0.012).Conclusion Both of prourokinase and reteplase are effective for the patients with acute myocardial infarction with ST -segment elvation,and prourokinase is safer.
