Stress-induced cardiomyopathy is characterized by transient systolic dysfunction of the apical or mid segments of the left ventricle that mimics myocardial infarction in the absence of obstructive coronary artery disease. Symptoms recur after a physical or emotional stress. We report a 77-year-old female that in 2004, suffered an episode of stress cardiomyopathy after an intense physical effort. In February 2010, immediately after the earthquake that occurred in Chile, the patient consulted for chest pain, ST segment elevation and enzyme elevation. An echocardiography showed a left ventricular anteroseptal akinesia with an ejection fraction of 35%. Coronary arteriography did not show significant alterations.
应激性心肌病的特征是左心室心尖段或中段短暂性收缩功能障碍,在无阻塞性冠状动脉疾病的情况下类似心肌梗死。身体或情绪应激后症状会复发。我们报告一名77岁女性,2004年在剧烈体力活动后发生了一次应激性心肌病发作。2010年2月,智利地震刚结束,该患者因胸痛、ST段抬高和酶升高前来就诊。超声心动图显示左心室前间隔运动不能,射血分数为35%。冠状动脉造影未显示明显异常。
