缺血心肌再灌注后常伴有心室节律紊乱、缺血的形态变化加重以及功能、代谢方面的恶化等,再灌注性损伤常伴随着心肌内出血,后者是由于微血管受到损害及血管内成份漏出的缘故。本实验的目的在于观察经不同时间缺血心肌微血管通透性的变化,以及其与再灌注性损伤的关系。 Ischemic myocardium often accompanied by ventricular dysfunction after reperfusion, increased morphological changes of ischemia and functional, metabolic deterioration, reperfusion injury often accompanied by myocardial bleeding, the latter is due to damage to the microvascular and the leakage of intravascular components The reason. The purpose of this experiment was to observe changes of microvascular permeability of ischemic myocardium at different time points and its relationship with reperfusion injury.
