Background: Tei index is an echocardiographic indicator for studying the function of ventricles. In most studies ,left Tei measurement was used to evaluate cardiac function in patients with heart failure, where its increase indicates left ventricular involvement. The following study was designed to compare right Tei index in healthy people with that of pulmonary patients in order to determine the effects of pulmonary diseases and their consequent cardiovascular complications.
Materials and Methods: The study population included 78 pulmonary patients and 37 normal individuals.
Doppler-echo imaging was performed by VingMed set, model CFM750 for all patients and the information was recorded in data sheets. Finally, results were analyzed by SPSS statistical software package, version 9.0.
Results: The mean (±SD) of age in the pulmonary patients and normal individuals was reported 49.28 ±19.11 and 36.57± 15.46 respectively. Meanwhile, Tei index was revealed to be independent of age, sex, ventricular geometry, pulse, and blood pressure, thus no interference resulted from intervening factors. The mean (± SD) of right Tei index was measured 0.47± 0.25 and 0.38± 0.16 in the pulmonary patients and normal individuals respectively.

Conclusion: Regarding the difference found between Tei index of these two groups, it seems as if significant change in Tei index is strongly associated with pulmonary disease. Therefore, it is worth surveying, the correlation between Tei index and other cardiac indices in pulmonary disease.(Tanaffos 2002;1(1):46-49)
