Abstract: Objective The aim of this study was to explore the evaluation of left ventricular functions by three-dimensional speckle tracking imaging (3D-STI) in patients with non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM). Methods 60 patients with NAFLD and T2DM (mild NAFLD in 30 and severe in 30) and 30 patients with T2DM were admitted in our hospital between June 2019 and June 2021. Serum fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were detected. The left ventricular end-diastolic diameter (LVDd), left ventricular end-systolic diameter (LVDs) and ratio of peak systolic velocity to end-diastolic velocity (E/A) were measured by routine two-dimensional ultrasound. The left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF) and left ventricular mass index (LVMI) were measured by real-time three-dimensional ultrasound. The left ventricular global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS) and global area strain (GAS) were detected by 3D-STI. Results Serum HbA1c, ALT and AST levels in patients with severe NAFLD and T2DM were (8.9±2.4)%,(127.2±16.9)U/L and (91.2±11.5)U/L, significantly higher than[(7.2±2.9)%, (61.6±10.4)U/L and (60.7±9.6)U/L, respectively, P<0.05] in patients with mild NAFLD and T2DM or [(7.0±2.5)%, (31.7±5.5)U/L and (33.5±4.8)U/L, respectively, P<0.05] in patients with T2DM; there were no significant differences in LVDd, LVDs, ratio of E/A, LVEF, LVEDV, LVESV and LVMI among the three groups (P>0.05); the GLS, GCS, GRS and GAS in patients with severe NAFLD and T2DM were (14.3±3.9)%, (17.3±3.3)%, (40.6±6.2)% and (24.1±4.6)%, significantly lower than [(17.7±2.8)%, (19.4±2.7)%, (44.9±8.7)% and (27.0±4.4)%, respectively, P<0.05] in patients with mild NAFLD and T2DM or [(18.9±2.4)%, (19.6±3.1)%, (45.5±6.4)% and (28.8±3.6)%, respectively, P<0.05] in patients with T2DM. Conclusion The 3D-STI detection could sensitively reflect changes of left ventricular functions in patients with NAFLD and T2DM, which is beneficial to correctly evaluate impairment of cardiac functions in this setting.
