摘要
目的 分析总结应激性心肌病的磁共振成像特点.方法 对确诊的6例应激性心肌病患者行心脏磁共振成像检查,对其磁共振成像特点进行分析总结.结果 所有患者左室射血分数降低（23％ ～45％,平均35％）,心室发生气球样变形（4例位于心尖,2例位于心室中部）;但受累节段无明显的坏死和纤维化,这与急性心肌梗死的磁共振成像特点不同.结论 应激性心肌病患者有典型的磁共振成像特点,有助于与急性心肌梗死的鉴别.
Objective To analyze and summarize the magnetic resonance imaging features of stress cardiomyopathy.Methods 6 cases with stress cardiomyopathy of confirmed diagnosis underwent cardiac magnetic resonance imaging,their imaging features were analyzed.Results All patients showed low left ventricular ejection fraction and ventricular apical or midventricular ballooning were detected in all the patients,but with no necrosis or fibrosis,which was different from the imaging features of acute myocardial infarction.Conclusions The typical magnetic resonance imaging features of stress cardiomyopathy are of great help in its identification from acute myocardial infarction.
