Abstract: Objective To evaluate the clinical application of the tissue Doppler imaging (TDI) in investigating the cardiac longitudinal systolic function in the patients with type 2 diabetes mellitus. Methods Forty-two patients with type 2 diabetes mellitus and 25 volunteers underwent TDI. The long axis myocardial peak systolic velocity (Sm), displacement (Dm) and strain rates (SRs) of 18 segments in different left ventricular walls were measured.Results The Dm and SRs of left ventricular wall in diabetic group dramatically decreased (P<0.01). Meanwhile, the diabetic combined hypertension group had much lower Sm of ventricular middle segments than the control group (P<0.05).Conclusion The stain rate and tissue tracking are sensitive and reliable to evaluate the early local cardiac systolic function in the patients with diabetes mellitus. TDI can be used as an noninvasive method to detect early systolic dysfunction.
