Eligibility
Inclusion criteria
Inclusion criteria: 1. The diagnosis of the PE patients must meet 2 conditions of the followings: (1) Selectivity pulmonary arteriography showes pulmonary artery obstruction or filling defect; (2) Lung ventilation-perfusion scan manifests single or multiple blood perfusion defect, venting normal or unmoral, venting-dabble matchless; (3) Clinical diagnosis: With risk factors for pulmonary embolism and clinical performance, electrocardiogram and chest film exclude other cardiovascular diseases and echocardiography, chest CT, blood gas analysis, D-dimer detection of combining support PTE diagnosis. 2. The diagnosis standard of Chronic Thromboembolic Pulmonary Hypertension (CTEPH) (1)The mean pulmonary artery pressure is >=25mmHg ,while pulmonary capillary wedge pressure(PCWP)is normal (<=15mmHg); (2) Lung ventilation-perfusion scan manifests single or multiple blood perfusion defect, venting normal or unmoral, venting-dabble matchless; (3) Clinical diagnosis: With risk factors for pulmonary embolism or VTE history, clinical exertional dyspnea for more than six months, electrocardiogram and chest film exclude other cardiovascular diseases and echocardiography, chest CT, blood gas analysis, D-dimer detection of combining support PTE diagnosis.
