STEMI:纤维蛋白特异性药物的颅内出血风险显著高于链激酶

  香港学者近期发表的一项研究表明,在ST段抬高型心肌梗死(STEMI)患者中,纤维蛋白特异性药物【TNK组织纤溶酶原激活剂(TNK-tPA)/阿替普酶】的溶栓后再灌注成功率仅略高于链激酶,但其颅内出血发生率显著升高。论文发表于《美国心脏病学会杂志》[J Am Coll Cardiol 2012, 59:]。

  对于适宜的STEMI患者而言,溶栓仍是一种重要的再灌注策略。颅内出血是一种潜在的致命性并发症。此项研究共纳入342例接受溶栓治疗的STEMI患者。通过医院药房、医院临床管理系统和急性心肌梗死(AMI)临床路径确认病例。利用SPSS16.0进行数据分析。

  结果显示,分别有266例(77.78%)和76例(22.22%)患者接受链激酶或纤维蛋白特异性药物(TNK-tPA/阿替普酶)治疗。颅内出血总发生率为1.46%。纤维蛋白特异性药物(TNK-tPA/阿替普酶)和链激酶组的颅内出血发生率分别为5.26%和0.38%(P=0.002)。在入院收缩压≥160 mmHg的患者中颅内出血发生率显著升高。在年龄≥75岁、女性以及伴卒中/短暂性脑缺血发作病史的亚组患者中颅内出血发生率升高。链激酶与应用溶栓药物时不良事件增多相关,其中包括低血压、心动过缓和过敏反应。TNK-tPA的再灌注成功率高于链激酶,但不具有统计学意义(P=0.246)。
