摘要
目的:探讨尿激酶( U K)不同剂量、发病后不同时间溶栓对急性心肌梗死( A M I)的疗效。方法:281例 A M I患者按 U K 剂量分成100万u、150万u、200万u 组,按发病时间分成≤2 h、> 2~4h、> 4~6 h、> 6~12 h 四个时间段。结果:3组的疗效无显著性差异( P > 0.05),而轻度出血100万u 组低于200万u 组( P < 0.05),且未发生重度出血及脑出血;虽血管再通率≤2 h 与> 6~12 h 有高度显著性差异( P < 0.01),但病死率及安全性在不同时间差异不明显(均 P > 0.05);6 h 内溶栓各剂量组再通率相近,而延迟溶栓(> 6~12 h)各剂量组再通率有较大差别(随剂量加大而升高)。结论: U K 100万u 是安全有效的剂量,特别是对发病6 h 内溶栓者;延迟溶栓仍有较大价值,并似可加大 U K 剂量以提高再通率。
Objective:To assess the efficacies of intravenous urokinase (UK) indiffent starting time of thrombolysis after onset of acute myocardial infarction (AMI) ,and explore its relationship with different dose of UK.Method:281 patients of AMI were treated with UK According to the different dose of Uk,281 cases were divided into 1.0 million U, 1.5 million U and 2.0 million U groups.The patients were also divided into≤2 hour, 2.1 ~4 hour, 4.1 ~6 hour and 6.1 ~12 hour groups,according to the different starting time of treating AMI.Result:The total patency rate of infarct related coronary arteries within 3 hours (including delayed patency) was 66.9 by clinical evidences of reperfusion and mortality in the first 5 weeks was 8.9 %.The efficacy of 1.0 million group was similar to 1.5 and 2.0 milion groups (all P> 0.05 ),while the rate of minor bleeding was higher (P< 0.05 ) in 2.0 million group than in 1.0 million group,the major bleeding occurred in 1.5 (1 case) and 2.0 million (1 case) groups,and 2 cases of intracranial hemorrhage occurred in 2.0 million group,too.The reperfusion rate was decreased as the thrombolysis was delayed, 79.2 % in ≤2 hour group and 54.0 % in 6.1 ~12 hour group (P< 0.01 ).However there was no significant difference of mortality and safety in all groups with different starting time (all P> 0.05 ).In addition,the patency rates of thrombolysis within 6 hours after onset had not difference in 3 doses groups,wheras the ones of delayed thrombolysis ( 6.1 ~12 hours) had major difference (respectively, 42.9 %, 57.1 % and 62.5 %),but no statistical significance (all P> 0.05 ).Conclusion:Intravenous UK 1.0 million U for AMI is effective and safer, especially in the patients treated within 6 hours; delayed thrombolysis has still major value, and its patency rate may be raised by increasing dose of UK.
