However, the relationship between the fractional flow reserve (FFR), the current gold standard for evaluating physiological myocardial ischaemia, and ESL has not been studied. The aims of this study were to investigate whether left ventricular (LV) ESL duration could identify patients with CAD, and to examine the relationship between FFR and LV ESL duration %K fractional flow reserve %K myocardial ischaemia %K speckle tracking echocardiography %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6307609/
