Usefulness of Two-Dimensional Speckle Tracking Echocardiography for Assessment of Tako-Tsubo Cardiomyopathy

The aim of this study was to characterize left ventricular (LV) systolic function using 2-dimensional strain in Tako-Tsubo cardiomyopathy (TTC). Forty-two women were prospectively studied using 2-dimensional speckle-tracking echocardiography, divided into 3 groups: 14 patients with TTC (group 1), 14 patients with coronary artery disease (group 2), and 14 healthy patients (group 3). In patients with TTC, mean values of systolic peak velocity, strain, and strain rate were significantly lower than those in group 3 (p
