ABSTRACT

Objective. To determine the usefulness of speckle-tracking in patients with ischemic dilated cardiomyopathy of the Hospital Juarez de Mexico, the period from march-december 2009. Material and methods. Study design: case series. By means of echocardiography with the Team Vivid 7, with the technique of speckle-tracking, and quantifying deformation via the bull-eye. Results. Echocardiography was performed in 37 patients, 31 men and 6 women. The global systolic strain generally decreased with an average of 8% and a standard deviation of 4. The segmental level systolic strain decreased on average in the 3 cameras to -9% in the 4 cameras to -8% in the two chambers -8%. Also describe the average, maximum and minimum found: In the anteroseptal segment -5% (7/-17), septal to -7% (8/-19), lateral to -6%, (19 / -19), prior to -7% (6/-18) subsequent to -9% (8/-23), less than 8% (8/-22). The ejection fraction averaged 30% (13%/51%), and an average diastolic diameter of 64 mm (53/88 mm), In making the correlation of the analyzed segments was observed that a correlation exists between the global strain of 3 cameras with p ‹0.005, as in the lower and later with p ‹0.005. Conclusion. Performing the longitudinal strain, through speckle techniquetracking is useful to know the deformation of a quantitatively in patients with dilated cardiomyopathy of ischemic origin. In our study it was observed that the strain decreases in all segments analyzed in the bull-eye, which correlates with the severity of reduced ejection fraction and severity of left ventricular dilation.
