摘要(Abstract)：
目的 应用心脏磁共振 (MR)影像特征评价急性冠状动脉综合征心肌不可逆缺血性损害。方法 35例临床诊断为急性冠状动脉综合征的患者 ,冠状动脉造影显示为多支冠状动脉未完全闭塞病变。心脏MRI观察梗死心肌形态并测定体积。结果 心脏MRI显示 35例患者心肌内存在延迟强化灶。本组病例的延迟强化灶以心内膜下型和局灶型为主 ,其所占比例为 85 7% (30 35 ) ,呈透壁型延迟强化的梗死病灶所占比例仅为 14 3% (5 35 )。心内膜下型 (12 95 %± 8 7% )和局灶型(13 3%± 0 5 7% )延迟强化灶的体积显著小于透壁型延迟强化灶 (4 5 7± 7 3% )。结论 心脏MR影像能够评价急性冠状动脉综合征多支冠状动脉狭窄所致的不可逆心肌损伤。
