心肌缺血再灌注损伤能够引起心肌细胞大量凋亡,可导致心脏结构的重构和心律失常[1]。临床表现为ST段抬高,心肌损伤范围增大,心肌形态学改变等。本实验在成功建立急性心肌缺血模型后,应用清开灵注射液,在心电图、心肌损伤范围,心肌形态学方面观察,初步探讨清开灵注射液(QKL)的 Myocardial ischemia-reperfusion injury can cause a large number of myocardial cell apoptosis, can lead to cardiac remodeling and cardiac arrhythmia [1]. Clinical manifestations of ST elevation, increased myocardial damage, myocardial morphological changes. In this experiment, after successfully establishing acute myocardial ischemia model, Qingkailing injection was used to observe the changes of electrocardiogram (ECG), myocardial injury area and myocardial morphology, and to explore the effect of Qingkailing Injection (QKL)
