Abstract
Objective:To investigate the clinical value of tissue Doppler Tei index in the evaluation on right ventricular function in patients with diabetes.Methods:33 diabetic patients and 34 healthy subjects served as control group who were examined by conventional echocardiography,the spectrograms about PW-TDI of tricuspid annulus were recorded at the same time,the related time intervals were measured,the Tei index were calculated.Results:① The Tei index in patients with diabetes increased obviously,the differences compared with control group had statistical significance(P0.01);② The linear element analysis showed: the Tei index in the control group had no relationship with age and rhythm of the heart(P0.05),the Tei index in patients with diabetes had positive correlation with age(P0.05),but no relationship with rhythm of the heart(P0.05).Conclusion:The Tei index of right ventricular acquired by TDI is simple,sensitive,noninvasive and accurate,it provides evidence for early diagnosis and treatment and prognosis of diabetic patients' right ventricular damage.
