Abstract
Global longitudinal strain (GLS) has emerged as a sensitive measure of left ventricular (LV) systolic function with greater prognostic value than ejection fraction (EF). While GLS is conventionally obtained from 2D speckle tracking echocardiography (2D-STE), it is not routinely derived from clinical cardiac magnetic resonance (CMR) imaging due to limitations in image features and temporal resolution. We sought to compare GLS measurements calculated from standard cine CMR analysis against conventional 2D-STE.
