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.
