Abstract:Objective: To study the clinical significance of detection of left ventricular torsion in patients with type 2 diabetes mellitus by two dimensional strain technique. Methods: 75 patients with T2DM in our hospital from March 2015 to September 2016 were selected, they were divided into simple diabetic group with 39 cases (group A) and diabetic complications group with 36 cases (group B) according to whether carrying vascular complications in clinical. In addition,35 healthy persons were selected as group C. The conventional echocardiographic parameters of subjects in three groups were measured, then two-dimensional high-frequent dynamic images were collected, and the peak value of left ventricular short axis base, apical systolic rotation angle (Rot-base, Rot-apex) and left ventricular systolic torsion angle (LV-tor) were obtained using two-dimensional strain software. Results: There was no significant difference in gender, age, heart rate, height and LVEF between the three groups (P>0.05), E/A in group B was lower than that in group A and group C (P<0.05). Rot-base, Rot-apex and LV-tor in group A were higher than those in group C (P<0.05), Rot-base, Rot-apex and LV-tor in group B were lower than those in group A and group C (P<0.05). Conclusion: When the left ventricular systolic function is normal in patients with diabetes mellitus, the left ventricular short axis torsional motion is abnormal. Left ventricular myocardial torsion angle in patients with diabetes mellitus can be exactly detected by two dimensional strain technique, and it can be used to assess whether the left ventricular function is impaired.
