Evaluation Of Right Ventricular Function In Patients With Pulmonary Hypertension Using Quantitative Tissue Doppler Imaging

Objective1.To explore the sequence of systolic and diastolic dysfunction in patients with pulmonary hypertension (PH) using tissue Doppler imaging (TDI).2. To quantitatively analyze myocardial diastolic velocities and time intervals of right ventricule in patients with pulmonary hypertension, evaluate right ventricular diastolic function and screen out the sensitive index of evaluating right ventricular diastolic function.3. To investigate the difference between systolic velocities and time intervals. of ri-ght ventricle myocardial motion and evaluate right ventricular systolic function.4. To investigate the value of Tei index in estimating right ventricular globle function in patients with pulmonary hypertension.Methods From July 2005 to August 2006, 78 patients with pulmonary hypertension including 41 men and 37 women with a mean age of 47. 7 ± 14. 2 years (ranged from 25 to 71 years) were divided into three groups (mild, moderate and severe groups) according to the degree of PH. There were...
