组织型纤溶酶原激活剂是一种天然存在的、选择性的血凝块纤溶激活剂。我们最近报道,从Bowes黑色素瘤组织培养上清液中分离的人组织型纤溶酶原激活剂溶解犬冠状动脉血栓,而不消耗循环纤维蛋白原或α2-抗纤溶酶,与链激酶和尿激酶的情况相反。在本研究中,7例进展性心肌梗死患者中有6例在19 ~ 50分钟内静脉或冠状动脉内注射组织型纤溶酶原激活剂诱导冠状动脉溶栓(经血管造影证实)。循环纤维蛋白原、纤溶酶原和α2-抗纤溶酶没有被这种药物清除,这与随后给予链激酶的2例患者的情况相反。在一个病人中,溶解是不诱导与组织型纤溶酶原激活剂,它也不是诱导与streptokinase.These观察表明,凝块选择性冠状动脉溶栓可以诱导患者与发展中的心肌梗死通过组织型纤溶酶原激活剂,没有伴随诱导的全身溶解状态。其治疗益处的定义必须等待更大的可用性的代理和适当的临床试验的性能。(N Engl J Med 1984; 310:609-13.)
Tissue-type plasminogen activator is a naturally occurring, clot-selective activator of fibrinolysis. We recently reported that human tissue-type plasminogen activator isolated from a Bowes-melanoma-tissue-culture supernate lysed coronary thrombi in dogs without depleting circulating fibrinogen or α2-antiplasmin, in contrast to the case with streptokinase and urokinase. In the present study coronary thrombolysis, confirmed angiographically, was induced within 19 to 50 minutes with intravenous or intracoronary tissue-type plasminogen activator in six of seven patients with evolving myocardial infarction. Circulating fibrinogen, plasminogen, and α2-antiplasmin were not depleted by this agent, in contrast to the case in the two patients subsequently given streptokinase. In the one patient in whom lysis was not inducible with tissue-type plasminogen activator, it was also not inducible with streptokinase.These observations indicate that clot-selective coronary thrombolysis can be induced in patients with evolving myocardial infarction by means of tissue-type plasminogen activator, without concomitant induction of a systemic lytic state. Definition of its therapeutic benefit must await greater availability of the agent and the performance of appropriate clinical trials. (N Engl J Med 1984; 310:609–13.)
