近年来,临床上对心肌梗塞患者多试行溶栓疗法(PTCR)、经皮冠脉血管成形术(PTCA)以及紧急A-C旁路术等冠脉血运重建术来抑制心肌坏死和缩小病灶。并通过超声心动图和左室造影等分析心室壁的运动情况,以评价局部病变心肌的生存性和判定上述手术的效果。在判定与评价血运重建术以及重建术后长期经过的新领域中,有学者提出,在最终坏死心肌与生存心肌之间,存在着所谓晕厥心肌(stunned myocardium)和冬眠心肌(hibernating myocardium)的病理变化。有报告,短时间重度缺血但在发病早期成功施行了血运重建术的急性心肌梗塞病例以及伴有较长时间冠状动脉完全闭塞的冠脉痉挛性心狡痛
In recent years, many patients with myocardial infarction in the clinical trial of thrombolytic therapy (PTCR), percutaneous transluminal coronary angioplasty (PTCA) and emergency A-C bypass surgery and other coronary revascularization to inhibit myocardial necrosis and lesion lesion. And through echocardiography and left ventricular angiography and other analysis of ventricular wall motion, in order to assess the survivability of local lesions and to determine the effect of the above surgery. In the new field of long-term evaluation and evaluation of revascularization and reconstructive surgery, some scholars have suggested that there is the so-called stunned myocardium and hibernating myocardium between the final necrotic myocardium and the living myocardium Pathological changes. It has been reported that acute myocardial infarction with short-term severe ischemia but successful revascularization at an early stage of onset and coronary spastic heart-soreness with prolonged complete coronary occlusion
