心肌缺血再灌注损伤(Myocardial Ischemia Reperfu-sion Injury,MIRI) 是近年来医学界的热点问题,其机理复杂,认为与Ca2+超载、自由基损伤、白细胞粘附和浸润及心肌细胞间的作用等有关[1]。此种损伤常见于急性心梗病人搭桥术、冠脉内溶栓术、冠脉内球囊扩张血管成形术及体外循?
Myocardial Ischemia Reperfusion Injury (MIRI) is a hot issue in the medical community in recent years. Its mechanism is complex, and it is considered that it is associated with Ca2+ overload, free radical damage, leukocyte adhesion and infiltration, and myocardial cell interactions. Related to [1]. This injury is common in patients with acute myocardial infarction bypass grafting, intracoronary thrombolysis, intracoronary balloon angioplasty and extracorporeal circulation.
