摘　　要：存活心肌包括顿抑心肌、冬眠心肌和重伤心肌,与梗死心肌的主要区别在于血流再通后收缩功能可完全或部分恢复。因此,判断缺血性心脏疾病患者缺血区心肌是否仍具有活力是指导临床是否需行血运重建术的重要指标。目前,如何准确、无创性地判断心肌活性已成为各种影像学研究的热点之一。本文对存活心肌的概念及不同影像学评价方法进行综述。Myocardial viability includes the stunned myocardium,hibernating myocardium and maimed myocardium.Different from infarction,the systolic function of the viable myocardium can completely or partially resume after recanalization.Whether the ischemic areas of patients with ischemic heart disease still have viable myocardium or not is an important indicator for revascularization.At present,how to accurately assess the myocardial viability has attracted more attention in non-invasive imaging resecarch.The concept and different imaging assessment of viable myocardium were reviewed in this article.
