Correlation study of Tei index measured by pulse Doppler and tissue Doppler echocardio-graphy in type 2 diabetes mellitus

Objective:To evaluate the correlation of the Tei index measured respectively by pulse Doppler and tissue Doppler echocardiography and investigate the clinical value of Tei index in assessing the left ventricular function of patients with type 2 diabetes mellitus. Methods: 80 patients with type 2 diabetes mellitus (40 patients with syndrome and 40 patients without syndrome) and 40 healthy adults as control subjects were enrolled in the study. The Tei index was obtained respectively by pulse Doppler and tissue Doppler echocardiography. Results:The value of Tei index by tissue Doppler was (0.61±0.25) and Tei index by pulse Doppler was (0.63±0.26). They were significantly related (r=0.81, P0.01). There was significant difference in the Tei index between each group in type 2 diabetes mellitus group and normal control group (P0.05, P0.01). Conclusion: The Tei index obtained by tissue Doppler echocardiography has clinical value in assessing the left ventricular function of patients with type 2 diabetes mellitus as same as that by pulse Doppler echocardiography.
