Abstract:
Objective To investigate the evaluation of Tei index on right ventricular function in patients with chronic obstructive pulmonary diseases ( COPD ). Methods Tirty-eight cases with COPD and ninty-eight healthy people were selected as COPD groups and normal control group. Tei index of right ventricular on echocardiography and pulmonary arterial systolic pressure were observed. Results (1) There were significant differeces of isovolumic relaxation time ( IRT) and isovolumetric contraction time ( ICT) , ejection time ( ET) and Tei index of right ventricular between healthy group and normal control group (P < 0.01). (2) In comparison of COPD group, it showed that tei index was changed by the degree of PAH(P< 0.01). There was significant differece in COPD group comparison (P < 0.01). (3) Tei index in right ventricular enlargement increased by PAH while decreased by volume load. Conclusions (1) Tei index is one of convenient, sensitive and general Doppler ultrasound index which can evaluate function of ventricular contraction and diastolic in patients with COPD. (2) Tei index in right ventricular enlargement was influced by pressure load and volume load, respectively. There was a correlation between the degree of right ventricular function damage and increasing of pulmonary arterial systolic pressure.
