Abstract

OBJECTIVE:

Using three-dimensional speckle-tracking echocardiography (3D-STE), we aimed to evaluate left ventricular (LV) function in type 2 diabetes mellitus (T2DM) patients with non-alcoholic fatty liver disease (NAFLD).

METHODS:

In total, 97 T2DM patients were categorized into three groups based on hepatic ultrasonography: group A (those without NAFLD, n=30), group B (those with mild NAFLD, n=32), and group C (those with moderate-to-severe NAFLD, n=35). Our conventional echocardiographic parameters included transmitral peak early and late diastolic velocity (E and A), septal and lateral early (e') mitral annular diastolic tissue velocities, and left atrial maximum volume index (LAVImax). LV end-diastolic and -systolic volume, LV mass index (LVMI), and LV ejection fraction were measured using real-time three-dimensional echocardiography. The 3D-STE parameters included LV global radial strain (GRS), global longitudinal strain (GLS), global area strain (GAS), and global circumferential strain (GCS).

RESULTS:

Our results showed that in group C, GCS, GRS, GLS, GAS, and septal and lateral e' velocity decreased, whereas average E/e' and LAVImax increased compared to groups B and A (p<0.05). Multiple linear regression analysis showed that NAFLD is independently associated with 3D-STE parameters, and glycosylated hemoglobin also has negative impacts on all LV 3D strains.

CONCLUSION:

When combined with conventional echocardiography, 3D-STE can assess LV function effectively in T2DM patients with NAFLD. Additionally, the severity of LV dysfunction in the moderate-to-severe NAFLD group (group C) was worse than the mild and absent NAFLD groups (groups A and B).
