Abstract: Objective To quantitatively evaluate the difference in global longitudinal strain(GLS)and global circumferential strain (GCS)of three-layers of cardium between diabetes mellitus (DM)patients using layer-specific speckle-tracking imaging.Methods Fifty-seven DM patients and sixty matched controls were enrolled in the study.GLS and GCS of three-layer cardium were assessed using layer-specific speckle-tracking imaging,available by GE Vivid E9 and EchoPac workstation.Results GLS of three-layer cardium in DM patients were significantly lower than those in normal controls (all P <0.05).GCS of endo-and mid-cardium were significantly lower in DM patients than in normal controls (P < 0.05 ).There was no statistical difference of GCS of epi-cardium between the two groups (P > 0.05 ).GLS and GCS of three-layer cardium was highest in endo-cardium and lowest in epi-cardium.Conclusions GLS of three-layer cardium may be a sensitive indicator of early left ventricular systolic dysfunction in DM patients with normal ejection fraction.
