An 83-year-old Caucasian female was referred for dobutamine stress echocardiography. At peak dobutamine stress, no chest pain was elicited, and there were no ischemic electrocardiographic changes or inducible wall motion abnormalities. During recovery, however, the patient experienced chest burning, and ST-elevations were seen on recovery electrocardiography. Moreover, distal inferior and apical akinesis developed during recovery echocardiography. The patient was referred for coronary angiography, revealing apical akinesis and no obstructive stenoses. A follow-up echocardiogram 2 weeks later showed recovery of the "ballooned" segments. To our knowledge, this report is the third case of Takotsubo cardiomyopathy occurring during the recovery phase of dobutamine stress echocardiography.
一名83岁的白种女性被转诊进行多巴酚丁胺负荷超声心动图检查。在多巴酚丁胺负荷峰值时，未诱发胸痛，也没有缺血性心电图改变或可诱导的室壁运动异常。然而，在恢复过程中，患者出现胸部烧灼感，恢复心电图显示ST段抬高。此外，在恢复超声心动图检查期间出现了心尖下壁远端运动减弱。患者接受了冠状动脉造影，显示心尖运动减弱且无阻塞性狭窄。两周后的随访超声心动图显示“球囊样”节段恢复。据我们所知，本报告是多巴酚丁胺负荷超声心动图恢复阶段发生的第三例应激性心肌病病例。
