摘　　要：随着对急性心肌梗死(AMI)、慢性冠心病及其并发症治疗的进展,导致带有左心功能不全生存的患者越来越多,已有研究表明,存活心肌对AMI后和慢性心力衰竭患者的预后判断及临床决策起到了重要作用。存活心肌是指冠状动脉缺血或缺血再灌注后收缩功能可逆性减低但仍有收缩储备的心肌,微血管的完整性与心肌的存活性对应。心肌超声造影(myocardial contrast echocardiography,MCE)能评估AMI及慢性冠心病患者心肌功能障碍区域内的微血管完整性,从而检测存活心肌并预测功能障碍区域再灌注后功能恢复的可能性,为临床医师的个体化治疗提供有价值的信息。Progress in the treatment of acute myocardial infarction（AMI）,chronic coronary artery disease and their immediate complications has led to an increasing number of surviving patients with residual left ventricular dysfunction.It has been shown that viable myocardium in post-AMI patients and chronic heart failure patients plays an important role in predicting their prognosis and making clinical decisions.Viable myocardium refers to myocardium with reversible contractile dysfunction that occurs in coronary ischemia or after ischemia-reperfusion,but still has contractile reserve.Myocardial microvascular integrity is in correspondence with myocardial viability.Myocardial contrast echocardiography can evaluate the microvascular integrity of myocardial dysfunctional areas in patients with AMI or chronic coronary artery disease,detect viable myocardium,predict the potential for functional recovery in dysfunctional areas following reperfusion,and provide clinicians with valuable information for individualized treatment.
