Assessment of left ventricular myocardial deformation according to Speckle-tracking echocardiography in the long-term period in patients with takotsubo syndrome

Abstract Funding Acknowledgements Type of funding sources: Public hospital(s). Main source(s): North-Western State Medical University named after I.I. Mechnikov Complete improvement left ventricle systolic function is an essential feature takotsubo syndrome (TTS). Speckle -tracking echocardiography (STE) provides quantitative information about myocardial deformation, more accurately than conventional echocardiography. Objective to assess the global longitudinal strain (GLS) and circumferential (GCS) by speckle-tracking in patients with TTS long-term period. Materials methods 14 female were monitored, average age 57.5 ± 28.5. The diagnosis was verified ventriculography 1 year attack, complaints patients, cardiovascular events (CE) signs heart failure evaluated. All underwent using a Vivid-4 (General Electric) Speckle-tracking function. ejection fraction (EF) (LV), zone disorders local contractility, level GLS GCS Results observation, all had good clinical condition, there no CE, absent. EF 56.3 3.45%; zones contractility found any patient. A below normal observed 7 (-12.05% 5.15%), (less -18%), reduced 3 (21.4%) (- 9.7 3.4%) at -18 below. Conclusions despite absence echocardiography, revealed 50% 20% patients. Thus, shows that some changes LV persist long term. It can be explained change orientation fibers due remodeling, but this requires further evaluation.
