不可逆性心肌缺血引起心肌细胞损伤,其程度依赖缺血程度与时间。防止心肌细胞坏死的唯一手段是使闭塞动脉再通。但近年认为心肌一过性缺血一再灌注时所致心肌细胞坏死原因除缺血外,还存在再灌注时造成存活心肌细胞的损伤。要区别缺血一再灌注后心肌损伤是由缺血所致还是由再灌注造成的并不容易,目前多数研究采取再灌注时给予药物或动脉血以外再灌注液与动脉血再灌注后心肌坏死最比较的方法。Rosenkraz与Buckberg等提出,由缺血后动脉血
Irreversible Myocardial ischemia caused by myocardial ischemia, the degree of ischemia-dependent degree and time. The only way to prevent necrosis of myocytes is to recanalize occluded arteries. However, in recent years, myocardial ischemia caused by myocardial ischemia caused by transient perfusion of myocardial ischemia in addition to ischemia, there is also the existence of myocardial cells during reperfusion injury. To distinguish between ischemia and reperfusion after myocardial injury caused by ischemia or reperfusion caused by not easy, the current study to take most of the reperfusion given drug or arterial reperfusion fluid and arterial reperfusion after myocardial necrosis Comparison of methods. Rosenkraz and Buckberg et al. Suggest that arterial blood from postischemic ischemia
