| Objectives | |
| Narrative objectives1 | It was considered that the pathogenesis of pulmonary arterial hypertension (PAH) and chronic thromboemblic pulmonary hypertension (CTEPH) could be associated with systemic inflammation. However, the focus of systemic inflammation has been unclear. The purpose of this study is to investigate the association between the alternation of intestinal flora and the severity of these pulmonary hypertensive disease. |
| Basic objectives2 | Others |
| Basic objectives -Others | This is an observation study. The association between composition of intestinal flora and hemodynamics of PAH or CTEPH patients |

| Assessment | |
| Primary outcomes | Following endpoints were evaluated at diagnosis, 6, 12,24,36 months after starting treatments.
1) The composition of intestinal flora by 16S rRNA analysis 2) Functional analysis by meta-genome analysis |
| Key secondary outcomes | Following endpoints were evaluated at diagnosis, 6, 12,24,36 months after starting treatments.
1) Right heart categorization 2) echocardiography 3) blood examination (BNP, UA, CRP) 4) fecal biochemistry (butyric acid, lactic acid) 5) analysis of oral flora 6) Physical activity |
