A 48-year-old woman presented to her local hospital with chest pain. Her electrocardiogram showed incomplete right bundle branch block, diffuse ST segment elevation and QTc prolongation. Shortly after admission, she became hypotensive and was referred for a coronary angiogram. Her coronary arteries were normal, but left ventriculography showed morphological changes typical of apical ballooning, as found in tako-tsubo cardiomyopathy. An echocardiogram confirmed complete akinesis of the left ventricular apex, with hyperkinesis of basal segments and an ejection fraction of 35% to 40%. Dynamic left ventricular outflow tract obstruction was also noted. After temporary support with intra-aortic balloon counterpulsation, fluids and noradrenaline, she recovered promptly. The present paper reviews the characteristic features of tako-tsubo cardiomyopathy.
一名48岁女性因胸痛前往当地医院就诊。她的心电图显示不完全性右束支传导阻滞、广泛ST段抬高及QTc延长。入院后不久,她出现低血压,遂转诊进行冠状动脉造影。其冠状动脉正常,但左心室造影显示出典型的心尖气球样变形态改变,这在应激性心肌病中可见。超声心动图证实左心室心尖完全运动消失,基底节段运动增强,射血分数为35%至40%。还发现了动态左心室流出道梗阻。在接受主动脉内球囊反搏、补液及去甲肾上腺素的临时支持治疗后,她迅速康复。本文综述了应激性心肌病的特征。
