摘要： 目的 探讨心肌收缩带坏死在心源性猝死中的病理学特征及意义。 方法 采用常规HE和PTAH染色方法制片，对心肌收缩带坏死的分布部位、病理学特征等进行观察，并按照坏死程度分级进行分析。 结果 心肌收缩带坏死在各猝死案例中的分布部位、病理学特征及坏死程度相似，其分布部位与心肌受损的部位有关，左心室乳头肌最易出现，其次为左心室前壁。应激性心肌病导致的猝死中心肌收缩带坏死程度较轻，以1级为多见，其他心肌病以2级为多见。 结论 心肌收缩带坏死可作为心肌急性缺血的诊断依据，并对死因的判断具有重要意义。

Abstract:  Objective To investigate the pathological features and significance of myocardial contraction band necrosis in sudden cardiac death. Methods Using HE and PTAH staining, the distribution sites and pathological features of myocardial contraction band necrosis were observed. The data were analyzed according to the extent of necrosis. Results The locations, pathological features and the extent of necrosis were similar in different sudden death cases. The locations were related with sites of myocardial damage. The papillary muscles of left ventricular were most occurred, followed by the anterior wall of left ventricular. In the sudden death cases caused by stress cardiomyopathy, the extent of myocardial contraction band necrosis was lighter than the others. Most cases were predominantly level 1, the others were level 2. Conclusion Used as the diagnosis basis of acute myocardial ischemia, the myocardial contraction band necrosis has important significance to determination of death.
