Motivation: To explore the application value of cardiac magnetic resonance (CMR) feature tracking technique in patients on maintenance hemodialysis(MHD).
Goal(s): To explore the application value of CMR feature tracking technique in patients on MHD.
Approach: CMR examination was performed in both groups, and the left ventricular myocardial strain values were obtained by FT-CMR to explore the differences in myocardial deformation between the two groups.
Results: With the increase of dialysis age, GCS, GRS and GLS were significantly lower than that in the low dialysis age group (-24.97±8.63 vs. -19.11±6.18, P=0.017; 23.31±9.96 vs. 33.23±15.88, P=0.022; -18.26±3.19 vs. -22.96±6.72, P=0.008).
Impact: In those with preserved ejection fraction, myocardial strain parameters are reduced, suggesting that the use of FT-CMR technique is helpful for early diagnosis of myocardial deformation injury in MHD patients.
