Quantification of Exercised-Induced Myocardial Deformation with Exercise CMR
Ex-CMR-derived MTR enables quantification of exercise-induced rotational deformation and mechanical reserve through single-beat myocardial tagging. In a pilot clinical study, MTR values distinguished patients with exercise-induced or overt HFpEF from individuals with non-cardiac dyspnea or healthy controls, supporting its potential utility as a marker of abnormal myocardial response to exercise.
