Background and Objective: Pulmonary hypertension is an increase in blood pressure of the pulmonary artery which leads to right ventricular dysfunction. Therefore, the present study aimed to compare echocardiographic parameters in the study of right ventricular failure in patients with pulmonary hypertension.
Materials and Methods: In the present descriptive cross-sectional study, data were collected from 100 patients with pulmonary hypertension referred to Farshchian Heart Hospital, Hamadan, Iran between 2017-2019.  The cases were detected by two-dimensional echocardiography and tissue Doppler and divided into three groups based on blood pressure of the pulmonary artery. The parameters of PASP, PVR, Tei Index, FAC, IVA, TAPSE, and DTI S Velocity were calculated for each patient.
Results: Out of 100 patients with a mean age of 52. 95 ±16. 62 years, 0. 46% had lung problems. The parameters of PASP, PVR, and Tei Index were positively and significantly correlated with each other. Also, a positive and significant relationship was observed between the parameters of FAC, IVA, TAPSE, and DTI S Velocity. However, the parameters of the first and second groups were negatively and significantly related to each other. The results indicated that the mean difference of all indicators was significant between different groups of pulmonary hypertension.  The parameter of PVR parameter was one of the factors affecting pulmonary hypertension based on regression analysis. Also, IVA and Tei Index were more consistent with pulmonary hypertension in terms of abnormal values.
Conclusion: PVR, IVA, and Tei Index were effective parameters for evaluating the right ventricular function and more attention is recommended to be paid to these parameters
