Takotsubo syndrome is a transient form of left ventricular dysfunction, more common in postmenopausal women, which involves left ventricular mid-apical akinesis and mimics acute coronary syndrome. It is characterized by left ventricular apical ballooning without significant coronary artery stenosis on coronary angiography. The basic mechanisms of Takotsubo cardiomyopathy are still unclear. There is some evidence that emotional, physical or pharmacological stress associated with increased catecholamine levels, coronary spasm, dynamic left ventricular obstruction, or coronary microvascular dysfunction might be involved. We describe the case of an 81-year-old woman who developed a Takotsubo syndrome only 3 h after pharmacological stress echocardiography with dipyridamole. To our knowledge, this is the first case reported in the literature in such context.

Abstract
Takotsubo syndrome is a transient form of left ventricular dysfunction, more common in postmenopausal women, which involves left ventricular mid-apical akinesis and mimics acute coronary syndrome. It is characterized by left ventricular apical ballooning without significant coronary artery stenosis on coronary angiography. The basic mechanisms of Takotsubo cardiomyopathy are still unclear. There is some evidence that emotional, physical or pharmacological stress associated with increased catecholamine levels, coronary spasm, dynamic left ventricular obstruction, or coronary microvascular dysfunction might be involved. We describe the case of an 81-year-old woman who developed a Takotsubo syndrome only 3 h after pharmacological stress echocardiography with dipyridamole. To our knowledge, this is the first case reported in the literature in such context.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
