据报告急性心(肌)梗(塞)溶栓治疗后,其中18～32%的患者复发心肌缺血,指需紧急冠(状动)脉成形术或外科搭桥术,病变冠脉再堵塞或者发生心源性猝死。预测那类患者易发再缺血,有助于决定施行血管重建术与否。以往认为静脉注射链激酶后仍残留高度冠脉狭窄者易再次发作。但上述研究中患者例数较少,且对冠脉狭窄的程度及与梗塞区供血冠状动脉的形态学无详细评价,因而
It has been reported that 18 to 32% of patients with recurrent myocardial ischemia after acute thrombus (thrombolytic) infarction (thrombolysis) may require emergency crown (dynamic) angioplasty or surgical bypass, re-occlusion of diseased coronary arteries or Sudden cardiac death. Predict the type of patients prone to ischemia, help determine the implementation of revascularization or not. In the past that intravenous streptokinase remains after the high degree of coronary stenosis who are prone to another episode. However, the number of patients in the above study is small, and the degree of coronary stenosis and infarction area with no detailed evaluation of coronary artery morphology, and thus
