Abstract:Objective To evaluate left ventricular function in early stage of diabetes mellitus by three-dimensional speckle tracking technique. Methods From January 2017 to April 2018, 83 patients with type 2 diabetes who were outpatient or hospitalized in the First Affiliated Hospital of Hebei North University were selected, including 44 cases of type 2 diabetes (diabetes group), 39 cases of diabetes complicated with hypertension (diabetes complicated with hypertension group), and 40 cases of healthy people in the same period (control group). Conventional echocardiography and three-dimensional speckle tracking technology were used to measure the overall left ventricular strain, including global longitudinal strain (GLS), global circumferential strain (GCS), global area strain (GAS), global radial strain (GRS) and three-dimensional left ventricular ejection fraction (3D-LVEF), and the differences between the three groups were compared. Results The value of conventional echocardiography such as two-dimensional left ventricular ejection fraction(2D-LVEF) in each groups had no significant difference(P > 0.05).Compared with the control group, GLS, GAS, GCS and GRS in the diabetes group were significantly reduced, with highly statistically significant differences (P < 0.01). GLS, GAS, GCS, GRS and 3D-LVEF were significantly reduced in the diabetes complicated with hypertension group, and the differences were highly statistically significant (P < 0.01). Compared with the diabetes group, GLS, GAS, GRS and 3D-LVEF in the diabetes complicated with hypertension group were decreased, and the differences were statistically significant (P < 0.05). Conclusion Three-dimensional spot tracking technology can detect changes in diabetic heart function early when 2D-LVEF is normal in diabetic patients, providing imaging basis for clinical prevention of diabetic heart and cerebrovascular complications.
