| Outline of Final Research Achievements |
The purpose of this study is to elucidate new pulmonary vascular biomarkers ; to find association of them with severity of pulmonary hypertension, surgical outcome in chronic thromboembolic pulmonary hypertension (CTEPH), prognosis; to investigate the association of activity of the biomarkers and gene polymorphism for personalized medicine. Pentlaxin-3 (PTX-3) was the most sensitive biomarker of CTEPH and may be useful marker for early diagnosis, although PTX3 levels did not correlate with the severity of the pulmonary hemodynamics even stratified by gene polymorphisms. Preoperatively high fibrinogen and low plasminogen values in CTEPH are associated with poor long-term postoperative outcome. For PET, accumulation on pulmonary arterial wall was high in some of CTEPH, but the level of SUV max was lower than sarcoma of the pulmonary artery. Finally we found 4 new pulmonary specific peptide biomarkers associated with CTEPH using the protein array method for screening of autoantibodies.
