Assessment of left ventricular twist mechanics in Tako-tsubo cardiomyopathy by two-dimensional speckle-tracking echocardiography

17 consecutive patients with typical Tako-tsubo cardiomyopathy (TTC) according to Mayo clinic criteria (mean age 78 ± 8 years, 88% women, mean LVEF 45 ± 10%), 17 age- and sex-matched controls (mean LVEF 70 ± 7%), and 17 patients with acute anterior MI treated by successful primary angioplasty 24 h before (matched for LVEF, age, and sex). Total n=51.
