Apical-sparing variant of Tako-Tsubo cardiomyopathy: prevalence and characteristics.

Background: Several patterns of Tako-Tsubo cardiomyopathy (TTC) have been described recently.

Aims: To assess the prevalence and characteristics of an apical-sparing variant of TTC.

Methods: This study included consecutive patients admitted to our catheterization laboratory for suspected acute coronary syndrome (ACS).

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 <0.

Prevalence and characteristics of left ventricular outflow tract obstruction in Tako-Tsubo syndrome.

Background And Objective: Tako-Tsubo syndrome is a clinical entity mimicking acute coronary syndrome (ACS). Left ventricular outflow tract (LVOT) obstruction may occur in Tako-Tsubo syndrome. The aim of this study was to determine the prevalence and features of LVOT obstruction in Tako-Tsubo syndrome in a population presenting with ACS.
