Two-Dimensional Echocardiography Strain Imaging for Viability Assessment in Ischemic Cardiomyopathy: Comparison with Cardiac Magnetic Resonance Imaging

Background: Two-dimensional (2D) speckle tracking echocardiography (STE) enables assessment of global and regional strain of the left ventricle (LV). Previous studies that strain imaging can ascertain myocardial viability. However, these studies were conducted principally in Europe and analysis done using EchoPac (General-Electric-Vingmed). There was no study using a different system (Philips-Qlab) and in an Asian...
