Data are expressed as the means±SD. CMR indicates cardiac magnetic resonance; EF, emptying fraction; LA, left atrial; LV, left ventricular; S_max, maximum strain; S_preA, pre‐atrial contraction strain; SR_a, strain rate at atrial contraction; SR_e, strain rate at LV early diastole; SR_s, maximum strain rate; V_max, maximum indexed volume; V_min, minimum indexed volume; V_preA, pre‐atrial contraction indexed volume.
