A 67-year-old woman was admitted with aneurysmal subarachnoid haemorrhage and a 12-lead ECG showed ST segment elevation. Transthoracic echocardiography confirmed akinesis of the left ventricular mid-apical segment, with an ejection fraction of 26%, features characteristic of takotsubo cardiomyopathy. Five days later, we identified thrombus in the apex of the left ventricle. Sixteen days after onset, the thrombus had disappeared and wall motion improved (ejection fraction 58%) without evidence of cardioembolism. Takotsubo cardiomyopathy is a cause of cardiac dysfunction after stroke, including SAH. It is characterised by transiently depressed contractile function of the left mid and apical ventricle, without obstructive coronary artery disease. Clinicians should suspect takotsubo cardiomyopathy in patients with subarachnoid haemorrhage who have an ECG abnormality. Echocardiography is needed to detect the distinctive regional wall motion abnormality. Despite its severity in the acute phase, takotsubo cardiomyopathy is self-limiting and its management is conservative.
一名67岁女性因动脉瘤性蛛网膜下腔出血入院,12导联心电图显示ST段抬高。经胸超声心动图证实左心室心尖中段运动减弱,射血分数为26%,这些特征是应激性心肌病的典型表现。五天后,我们在左心室心尖部发现血栓。发病16天后,血栓消失,室壁运动改善(射血分数58%),且无心脏栓塞证据。应激性心肌病是包括蛛网膜下腔出血在内的中风后心脏功能障碍的一个原因。其特征是左心室中部和心尖部收缩功能短暂性降低,而无阻塞性冠状动脉疾病。临床医生应怀疑蛛网膜下腔出血且心电图异常的患者患有应激性心肌病。需要进行超声心动图检查以检测独特的节段性室壁运动异常。尽管应激性心肌病在急性期病情严重,但其具有自限性,治疗以保守治疗为主。
