The "tako-tsubo" syndrome, initially described by Japanese authors is an apical akinesis of the left ventricule without significant coronary artery disease, with a moderate elevation of troponine I. We report 2 cases of women (with an average age of 68 years). They were refered for suspected acute coronary syndrome including on admission chest pain and ST segment elevation. Cardiac ultrasonography shew an apical akinesis. Coronary angiography didn't show significant coronary lesion. A moderate elevation of troponine was noted but no significant elevation of CPK. The prognosis has been excellent for these 2 patients. We observed a ventricular tachycardia due to QT lengthening in 1 case treated anteriorly by Flecaïn which spontaneously resolved. The first month, the electrocardiogram and cardiac ultrasonography anomalies disappeared totally. The treatment is based on beta-blockers, aspirin, statines, ACE. In the two cases, we didn't find arguments for myocarditis, recanalized thrombosis, coronary spasm, pheochromocytomas, but a risk factor is inboth: emotional stress. Maybe the diagnosis could be easier with the submillimeter cardiac computed tomography.

Introduction Y Objectives: Tako-tsubo syndrome (TTS) is a cardiac condition that mimics acute coronary syndrome, characterized by transient left ventricular dysfunction in the absence of culprit coronary artery stenosis. Although its etiology remains unknown, reversible microvascular dysfunction secondary to an adrenergic surge is thought to play a role. Treatment is empirical, although most patients receive beta-blockers (BB) in clinical practice.

Since its first description in 1990, Takotsubo cardiomyopathy (TC) has continued to puzzle physicians and scientists alike as the mechanisms behind the characteristic unique left ventricular dysfunction that marks the condition and its relation to the intense emotional and physiological stressors that usually precede it have remained not fully understood. Since then, several different variants of the condition have been described that do not conform to the conventional narrative of a post-menopausal disease that only affects women of a certain age and is triggered by a preceding event. Of these variants, atypical Takotsubo, which does not assume the typical characteristic apical ballooning that marks the condition has been linked with a younger age group and a more neurological trigger.

Takotsubo syndrome (TTS) is characterized by transient left ventricular dysfunction without obstructive coronary artery disease, often mimicking acute coronary syndrome. Its association with diabetes mellitus and arrhythmias, such as atrial fibrillation (AF), suggests potential shared pathophysiological mechanisms. We report the case of a 76-year-old woman with diabetes who developed sudden, severe chest pain and palpitations after cataract surgery.
