Abstract：Objective: To analyze the correlation of the collapsible index of inferior vena cava (cIVC) and the Doppler flow pattern with pulmonary artery pressure by echocardiography technology in the patients with pulmonary hypertension. Methods: The internal diameter of the inferior vena cava was measured in 76 cases of pulmonary hypertension patients (including 34 cases of mild severity, 27 cases of moderate severity, and 15 severe cases) and 46 healthy subjects as the control group at the end of expiration and inspiration by conventional transthoracic echocardiography, the collapsible index of inferior vena cava was calculated, at the same time, inferior vena caval flow spectrum feature was compared. Results: The internal diameter of inferior vena cava of three group of patients with pulmonary hypertension (mild group, moderate group and severe group) at the end of expiration and inspiration was higher than that of the control group (P<0.05), cIVC of the treatment group was lower than that of the control group (P<0.05). S wave and D wave, a wave of inferior vena cava spectrum of moderate and severe pulmonary hypertension group were different from that of the control group (P<0.05) in comparison. Conclusion: Collapsible index of inferior vena cava and blood flow spectrum feature have important predictive value for pulmonary hypertension.
