Reproducibilidad del strain longitudinal global del ventrículo izquierdo por ecocardiografía bidimensional speckle tracking: Estudio Longitudinal de Salud del Adulto (ELSA-Brasil)

There was adequate reproducibility of the left ventricular global longitudinal strain measurements in participants of the ELSA-Brasil study, and the values were similar to those reported in other longitudinal epidemiological studies. The findings reinforce the use of the global longitudinal strain as a clinical marker of myocardial deformation, capable of detecting subclinical changes in myocardial contractility.
