Title: Coronary Angiography in Out-of-Hospital-Cardiac-Arrest (OHCA)

题目：冠状动脉造影在院外心脏骤停（OHCA）中的应用

Author 作者: Semhar Tewelde

Acute coronary thrombotic occlusion is the most common trigger of cardiac arrest.

急性冠状动脉血栓形成性阻塞是心脏骤停最长见的诱发因素。

The benefit of coronary angiography seems to be well established in patients who regain consciousness soon after recovery of spontaneous circulation (ROSC).

冠状动脉造影在自主循环恢复后很快清醒病人的应用价值好象已经建立（ROSC）。

Whether emergency coronary angiography and PCI improve survival in patients who remain unconscious after ROSC remains unknown.

但是，紧急冠状动脉造影和经皮冠状动脉介入能否改善ROSC后意识没有恢复病人的预后还不清楚。

Results of this study can be summarized as follows:

这个临床研究结果可以归纳为如下几点：

1. CAD and acute or recent culprit coronary lesions are present in most resuscitated unconscious patients with OHCA without obvious extracardiac cause.

多数OHCA复苏后神志不清并没有明显心源性原因的病人可发现有冠心病和急性或新近发生的冠状动脉病变。

2. CAD and acute or recent culprit coronary lesions are observed in most patients with ST-segment elevation and in a non-negligible proportion of patients with other ECG patterns on post-ROSC electrocardiograph.

多数有ST段抬高和相当比例ROSC后有心电图变化的病人可发现有冠心病和急性或新近发生的冠状动脉病变。

3. Emergency coronary angiography and successful emergency PCI are independently related to in-hospital survival after OHCA.

紧急冠状动脉造影和成功的紧急PCI与改善OHCA后住院生存率有独立的关系。
