Materials and Methods: We recruited 12 patients with LVNC and 12 DCM patients for CMR examination and measured left ventricular (LV) function and tissue tracking parameters, including global and regional (basal, middle and apical) radial, circumferential and longitudinal peak strain(PS), peak systolic strain rate (PSSR) and peak diastolic strain rate (PDSR). LV tissue tracking parameters were compared between LVNC patients and DCM patients. Results: Among the global tissue tracking parameters, radial PS (9.63 ± 4.57 % vs. 18.65 ± 13.22 %, p = 0.036), radial PDSR (-0.62 ± 0.40 1/s vs. -1.75 ± 1.36 1/s, p = 0.011), and circumferential PDSR (0.36 ± 0.19 1/s vs. 0.76 ± 0.49 1/s, p = 0.015) were significantly lower in DCM patients than in LVNC patients. Besides, both the radial PS, radial PDSR radial and circumferential PDSR of the basal, middle and apical regional were obviously lower in the DCM patients compared with the LVNC patients (all p< 0.05). Furthermore, within the LVNC patients, the Pearson’s correlation indicated an excellent correlation between the LVEDV and radial PS (r = −0.852, p< 0.001). Conclusions: CMR tissue tracking could be useful in differentiating between LVNC patients and patients with DCM, which could potentially be included as a supplementary diagnostic procedure in the evaluation of LVNC.
