现已证明,红细胞聚集性明显增强与变形能力显著降低是急性心肌缺血时体循环血液流变学的特征性变化之一,前者使低切变率下全血粘度升高,后者则可通过增大发生逆转现象的临界血管半径,加重微循环栓塞。但有关缺血区局部循环血中红细胞聚集性与刚性变化的特征及其影响因素,迄今尚未深入研究。为此本实验观察了急性心肌缺血早期体循环血与缺血区局部 It has been demonstrated that a significant increase in erythrocyte aggregation and a significant decrease in deformability is one of the characteristic changes in systemic blood rheology during acute myocardial ischemia. The former results in an increase in whole blood viscosity at low shear rates, the latter by Increase the occurrence of reversal of the critical vascular radius, increase microcirculation embolism. However, the characteristics and influencing factors of the changes of erythrocyte aggregation and rigidity in the blood of partial ischemia in ischemic area have not been studied deeply. To this end the experiment observed early acute myocardial ischemia and blood circulation in the ischemic area
