CMR: cardiac magnetic resonance; early peak filling rate; A: atrial peak filling rate; e’: early diastolic myocardial relaxation velocity; NE: normalized peak E filling rate; NA: normalized peak A filling rate; E/A: E/A ratio; E’: early longitudinal relaxation rate. Echocardiography corresponds to Doppler echocardiography.
