Abstract:
Objective:To investigate the difference in left ventricular dysfunction between type 2 diabetes mellitus (T2DM) patients with hyperlipidemia and those without hyperlipidemia, and analyze the application value of three-dimensional speckle tracking technology.Methods:The clinical data of 70 patients with T2DM admitted to Heji Hospital Affiliated to Changzhi Medical College from January 2020 to June 2021 were retrospectively analyzed. Among these patients, 35 patients had hyperlipidemia and 35 patients had no hyperlipidemia. At the same time, 40 healthy subjects who concurrently underwent health checkups in the same hospital were included as healthy controls. All subjects underwent routine cardiac ultrasound and 3D-STE examinations. General clinical information and left ventricular function-related parameters, including global longitudinal strain, global circumferential strain, global area strain, and global radial strain were compared between healthy controls and T2DM patients with hyperlipidemia and those without hyperlipidemia.Results:The proportion of left ventricular remodeling increased in T2DM patients without hyperlipidemia, and the proportion of left ventricular hypertrophy was the highest in T2DM patients with hyperlipidemia. Global longitudinal strain and global circumferential strain in T2DM patients without hyperlipidemia were (-16.97 ± 2.59)% and (-17.41 ± 2.50)%, respectively, which were significantly higher than (-18.86 ± 2.46)% and (-18.71 ± 2.92)% in healthy controls ( t = 0.95, 0.57, both P < 0.05). Global longitudinal strain, global circumferential strain, and global area strain in T2DM patients with hyperlipidemia were (-14.98 ± 3.15)%, (-15.80 ± 3.16)%, (-27.17 ± 4.54)%, respectively, which were significantly higher than (-18.86 ± 2.46)%, (-18.71 ± 2.92)%, (-30.62 ± 4.02)% in healthy controls ( t = 0.46, 1.37, 0.98, all P < 0.05) and (-16.97 ± 2.59)%, (-17.41 ± 2.50)%, (-30.06 ± 3.59)% in T2DM patients without hyperlipidemia ( t = 0.37, 1.02, 0.77, all P < 0.05). Global radial strain in T2DM patients with hyperlipidemia was significantly higher than [(51.49 ± 8.94)%, t = 1.35, P < 0.05] in healthy controls and [(47.71± 8.46)%, t = 0.98, P < 0.05] in T2DM patients without hyperlipidemia. In patients with T2DM, fasting blood glucose and hyperlipidemia were independently correlated with all strain-related parameters. Conclusion:Hyperlipidemia can aggravate left ventricular remodeling and dysfunction in patients with T2DM and 3D-STE is one of the examination methods for subclinical left ventricular remodeling and dysfunction in T2DM patients with or without hyperlipidemia.
