摘要
急诊经皮冠状动脉介入治疗是目前治疗急性心肌梗死的首选方法。在大部分急性心肌梗死的患者中,急诊冠脉造影均显示存在较重的血栓负荷,而对富含血栓的冠状动脉行介入操作必然会增加远端栓塞的可能性。约13%~80.9%的病人术后出现慢血流或无再流现象,远端微循环栓塞系造成无再流现象最重要的原因之一。近年来问世的各种远端保护装置为防治远端栓塞提供了一种有效的方法。
Percutaneous coronary intervention (PCI) is of choice in the treatment of acute myocardial infarction (AMI). Emergent angiogram showed lots of thrombi in the coronary of most AMI patients, so emergent PCI may increase the possibility of distal embolization in these patients, slow-flow or no-reflow phenomenon in 13%-80.9% of the patients, and distal embolization is one of the main reasons for no-reflow phenomenon. In reeent years, several distal protective devices have been invented and provided effective ways for the prevention of distal embolization.
