Quantification of myocardial deformation in Ex-CMR real-time tagging imaging. a A 55-year-old male with a history of heart failure with preserved ejection fraction. Real-time tagging images were acquired pre- and post-exercise in short-axis views. Quantification of myocardial deformation shows a minimal response. b A 63-year-old male with a history of heart failure with reduced ejection fraction. Quantification of showed an augmented myocardial deformation
