尽管最近有报道早期应用溶栓剂可降低急性心肌梗塞(AMI)死亡率,但再梗塞或反复缺血仍多见。多数病人仍残留高度狭窄(残窄)。急症经皮腔内冠脉成形术(PTCA)有可能减轻狭窄,防止再缺血。随着静脉溶栓广泛应用,如何选择需要早期血管重建术的病人将日趋重要,本文试通过血管造影作出判断。方法50例AMI均于症状出现6h内按3:1髓机分组,分别接受重组型组织纤维蛋白溶酶原激括剂(t-PA)或安慰剂,于60、90l及120分钟行冠脉
Despite the recent reports that early use of thrombolytic agents reduces the mortality of acute myocardial infarction (AMI), reinfarction or recurrent ischemia is still common. Most patients remain highly stenosis (residual). Emergency percutaneous transluminal coronary angioplasty (PTCA) may reduce stenosis and prevent re-ischemia. With the widespread use of intravenous thrombolysis, how to choose the patients who need early revascularization will be more and more important. This paper tries to make the judgment by angiography. Methods Fifty patients with AMI were divided into 3 groups according to 3: 1 medullary machine within 6 hours after symptom onset, and received recombinant tissue plasminogen activator (t-PA) or placebo respectively. The coronary arteries were obtained at 60, 90, 120 minutes
