摘要

急性心肌损伤，如心外膜、壁内和心内膜下出血和水肿，已知发生在机械灌注后。动物实验结果表明，由于血液的机械损伤(红细胞聚集、变性)和/或持续的低灌注(微循环缺氧)引起的局部循环障碍(低灌注、缺氧)是急性病变的原因。此外，该结果为灌注后心力衰竭提供了形态学解释。

Structural changes in the heart due to mechanical perfusion.

Acute myocardial damage such as epicardial, intramural and subendocardial haemorrhages and oedema are known to occur after mechanical perfusion. The results of animal experiments showed that local circulatory disturbances (hypoperfusion, hypoxia) due to mechanical damage of the blood (erythrocyte aggregation, denaturation) and or lasting hypoperfusion (microcirculatory hypoxia) are responsible for the acute lesions. In addition, the results offer a morphological explanation for the postperfusion heart failure.
