Stress cardiomyopathy (SCM) is usually precipitated by a physiologically or psychologically stressful event. Although it occurs only rarely, hypoxia- and hypercapnia-induced sympathetic activation may also cause SCM. We present the case of a 37-year-old woman affected with SCM after a routine colonoscopy. During the procedure, she aspirated residual polyethylene glycol from her stomach. Hypotension, resting dyspnea, and hemoptysis were subsequently observed. Laboratory findings revealed elevated cardiac enzymes, and a transthoracic echocardiogram revealed left ventricular (LV) global hypokinesia. She was ultimately diagnosed with diffuse alveolar hemorrhage-associated SCM. After successful treatment with a ventilator and corticosteroids, her LV systolic function and dimensions normalized and she was discharged without complications.
应激性心肌病(SCM)通常由生理或心理应激事件诱发。尽管其发生率很低,但缺氧和高碳酸血症诱导的交感神经激活也可能导致SCM。我们报告一例37岁女性在常规结肠镜检查后发生SCM的病例。检查过程中,她从胃中吸入了残留的聚乙二醇。随后观察到低血压、静息性呼吸困难和咯血。实验室检查结果显示心肌酶升高,经胸超声心动图显示左心室(LV)整体运动减弱。她最终被诊断为弥漫性肺泡出血相关性SCM。在使用呼吸机和皮质类固醇成功治疗后,她的左心室收缩功能和尺寸恢复正常,出院时无并发症。
