近年来发现,急性冠脉综合征的患者,粥样斑块破裂、溶栓治疗或经皮冠状动脉介入(PCI)术后,残余的小碎屑随血流流至微动脉,阻塞远端血管,形成微血栓,造成微循环障碍,临床上出现致命性心律失常、心衰、猝死等表现。一、微栓塞与无复流现象1974年 Kloner 等在狗实验中发现结扎狗的冠状动脉造成心肌局部缺血后,再开放结扎动脉,重新恢复血流,部分缺
In recent years, found that patients with acute coronary syndromes, rupture of atherosclerotic plaque, thrombolytic therapy or percutaneous coronary intervention (PCI), the residual small debris flow to the arterioles with blood flow, obstruction of distal blood vessels , The formation of micro-thrombosis, causing microcirculation, clinical manifestations of fatal arrhythmia, heart failure, sudden death and other performance. First, the micro-embolism and no-reflow In 1974, Kloner and other experiments in dogs found that dog ligation of the coronary arteries caused by myocardial ischemia, and then open the artery ligation and resumption of blood flow, some lack
