急性心肌梗死是部分心肌的血液循环突然中断而导致该部位的心肌损伤.早期靶血管的开通是治疗急性心肌梗死的关键,溶栓与冠状动脉介入治疗(PCI)已广泛应用,而再灌注后存活心肌的检测、损伤血管的再灌注情况、可逆性损伤的恢复、微循环障碍、心脏的结构与运动功能等都需要评估,不同影像学技术对PCI术后心脏整体功能的评估侧重点各有不同,且在PCI术后的不同时间段价值也不相同.本文就超声心动图、心脏磁共振、核素显像对心肌再灌注后不同时期心脏的评估作一综述.%The acute myocardial infarction is a myocardial damage caused by the sudden interruption of part blood circulation of myocardium.The opening of early target vessels is the key to treat acute myocardial infarction,the thrombolysis and coronary interventional therapy (PCI) have been widely used,and the myocardium detection after reperfusion,the reperfusion of damaged vessels,recovery of reversible injuries,microcirculatory disturbance,structure and motor function of heart and so on all need to be evaluated.Different imaging techniques have different assess priorities for the cardiac function after PCI,and different time periods have different values after PCI.This paper reviews the echocardiography,cardiac magnetic resonance (CMR) and radionuclide imaging in the assessment of heart at different periods after myocardial reperfusion.
