Ischemic heart disease (IHD) remains the single most common cause of death worldwide. Ischemic cardiomyopathy is a major sequel of coronary artery disease. The economic health burden of IHD is substantial. In patients with old myocardial infarction (OMI), the extent of viable myocardium (VM) directly affects the short- and long-term outcome. There is a considerable collection of observational data showing substantial improvement in patients with significant left ventricular dysfunction when the need for revascularization is guided by preoperative assessment of viability and hibernation. However, a major challenge for present cardiovascular imaging is to identify better ways to assess viable but inadequately perfused myocardium and thus optimize selection of patients for coronary revascularization. Several non-invasive techniques have been developed to detect signs of viability. Hence, our aim is to provide the reader a state-of-the art review for the assessment of myocardial viability.
缺血性心脏病（IHD）仍然是全球范围内最常见的单一死因。缺血性心肌病是冠状动脉疾病的主要后遗症。IHD的经济健康负担巨大。在陈旧性心肌梗死（OMI）患者中，存活心肌（VM）的范围直接影响短期和长期预后。大量观察数据表明，当根据术前存活能力和冬眠评估来指导血运重建需求时，严重左心室功能不全患者的情况有显著改善。然而，当前心血管成像面临的一个主要挑战是找到更好的方法来评估存活但灌注不足的心肌，从而优化冠状动脉血运重建患者的选择。已经开发了几种非侵入性技术来检测存活迹象。因此，我们的目的是为读者提供一篇关于心肌存活能力评估的最新综述。
