The ELSA-Brasil Study and Our Myocardial Deformation

The analysis of myocardial deformation (strain) using speckle tracking technology in echocardiography is no longer something new and innovative. Several years have passed since its validation. Compared to left ventricular (LV) ejection fraction, global longitudinal strain (GLS) is a more accurate assessment of systolic function, important in several situations, such as cardio-oncology, valvular heart disease, cardiomyopathies, and ischemic heart disease. It is more accurate and reproducible data, is closely correlated with prognosis, and is currently available in most echocardiogram machines. [...]
