Diagnostic Accuracy of Global Longitudinal Strain and Speckle-Tracking-Derived Ejection Fraction for the Detection of Reduced Left Ventricular Ejection Fraction on Cardiac Magnetic Resonance: A Secondary Diagnostic Accuracy Analysis

2026-07-14

Abstract excerpt

<h4>Background</h4> Global longitudinal strain (GLS) and speckle-tracking-derived left ventricular ejection fraction (LVEF) are increasingly used to assess systolic function, but no consensus cut-off exists for identifying reduced LVEF as defined by cardiac magnetic resonance (CMR), the imaging reference standard. Our group previously reported excellent concordance between echocardiographic and CMR-derived LVEF i...
