We report a case of Tako-tsubo cardiomyopathy (TTC) occurring after colonoscopy. A 60-year-old post menopausal female with syncope following an acute abdominal syndrome underwent diagnostic colonoscopy. Anginal chest pain with marked ST segment elevation occurred the day following the procedure. Coronary angiogram was entirely normal, but left ventriculography showed marked reduction in systolic function along with mid ventricular and apical akinesis. The patient's symptoms completely improved with eventual normalization of ventricular function. The occurrence in this patient of initial vagal syndrome followed by sympathetic stimulation preceding TTC is compared to prior reports with similar provocateurs and implications for pathogenesis discussed.
我们报告了一例经结肠镜检查后发生的心尖球囊样综合征（Tako-tsubo 心肌病，TTC）。一位 60 岁绝经后女性，在急性腹痛综合征后出现晕厥，接受了诊断性结肠镜检查。在操作后的第二天出现心绞痛样胸痛，并伴有明显的 ST 段抬高。冠状动脉造影完全正常，但左心室造影显示收缩功能明显降低，伴有中部和心尖部无运动。随着心室功能的最终正常化，患者的症状完全改善。该患者 TTC 发生前，初始迷走神经综合征继之以交感神经刺激，与先前类似促发因素的报告进行了比较，并讨论了发病机制的影响。
