Three-dimensional speckle tracking echocardiography in evaluation on left ventricular function in type 2 diabetes mellitus patients with non-alcoholic fatty liver disease / 中国医学影像技术

ABSTRACT

Objective: To evaluate the feasibility of three-dimensional speckle tracking echocardiography (3D-STE) in evaluating left ventricular (LV) function in type 2 diabetes mellitus (T2DM) patients with non-alcoholic fatty liver disease (NAFLD). Methods: Totally 30 T2DM patients without NAFLD (group A), 32 T2DM patients with mild NAFLD (group B) and 35 T2DM patients with moderate to severe NAFLD (group C) underwent 3D-STE. Echocardiographic parameters were obtained, including conventional parameters of the ratio of transmitral peak early to late diastolic velocity (E/A), interventricular septum thickness diastolic (IVSTd), posterior wall thickness diastolic (PWTd), LV end-diastolic diameter (LVDd) and LV end-systolic diameter (LVDs), as well as LV function parameters including end-systolic left atrial volume (LAV), LV mass (LVM), LV end-diastolic volume (LVEDV), LV end-systolic volume (LVESV), LV mass index (LVMI) and LV ejection fraction (LVEF), also 3D-STE parameters including global longitudinal strain (GLS), global area strain (GAS), global radial strain (GRS) and global circumferential strain (GCS). The correlation of 3D-STE parameters and glycosylated hemoglobin (HbA1c), body mass index (BMI) were analyzed with Pearson linear correlation analysis. Results: There was no difference of E/A, IVSTd, PWTd, LVDd, LVDs, LVMI, LVEF, LVEDV nor LVESV among the 3 groups (all P>0.05), but patients in groups B and A had higher GCS, GRS, GLS and GAS than in group C (all P0.05). Conclusion: 3D-STE can be used to assess LV function in T2DM patients with NAFLD.
