Background: Takotsubo syndrome (TTS) is characterized by transient abnormalities of myocardial contractility. Noninvasive tests are currently being sought to differentiate TTS from acute coronary syndrome (ACS). The aim of the study: To evaluate the prevalence of TTS and echocardiographic parameters to distinguish apical TTS from acute anterior wall infarction. Material and methods: The medical records of patients with suspected TTS, hospitalized in the Department of Cardiology (TTS group n = 18) were analyzed. The control group included patients with STEMI of the left ventricle anterior wall and anterior and lateral wall (STEMI group n = 17). Standard transthoracic echocardiography (TTE) was supplemented with segmental longitudinal strain (LS) assessment with the use of acoustic marker tracking. Results: A statistically significant difference was observed in the second cardiac troponine I (CTNI) measurement (TTS: 3241.2 ng/L vs. STEMI: 12032.6 ng/L; p < 0.05).A significant difference in left and right ventricular size was observed on TTE. Left ventricular end-diastolic and end-systolic volumes were considerably smaller in TTS group; (86.1 vs. 104 ml and 48.1 vs. 74.1 ml, respectively). LS were significantly higher (in absolute values) in patients with TTS than in those with STEMI in the apical and middle lateral segments, LS in the apical four-chamber view (apSept −14.9 vs. −8.9; apLat −14.8 vs. −6.84; midLat −13.26 vs. −9.11). Conclusions:Patients with TTS are characterized by a different LS pattern in the apical segments of the left ventricle compared to patients with STEMI. TTE examination with LS remains insufficient to distinguish TTS from ACS at the early stage of diagnosis.
