Background: Tako-tsubo Syndrome (TTS) is characterized by transient regional systolic dysfunction of the left ventricle (LV), mimicking myocardial infarction. It accounts for 0.9-1.2% of all acute coronary syndromes (ACS). Aim: To describe the incidence and characteristics of TTS within our population. Material and Methods: All patients diagnosed with ACS and TTS were selected from a clinical registry of all the coronary angiographies done in our hospital.

Since then, 4,433 coronary angiographies were done to patients with ACS until 2014 and 37 corresponded to TTS (0.83% incidence). The mean age of patients was 64 years, 73% were female, and 62% had hypertension. All patients had an identifiable trigger factor, abnormal EKG and elevated troponin. The coronary
