Objectives
Narrative objectives1	Pulmonary hypertension such as pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) is a disease with poor prognosis, even though several specific drugs are available. In this retrosepctive study, we evaluate parameters such as hemodynamics, cardiac function, pulmonary function or exercise tolerance to assess the relationship between these parameters and known prognostic factors.

Assessment
Primary outcomes	In this study, we evaluate parameters such as hemodynamics, cardiac function, pulmonary function, which are related to known prognostic factors such as cardiac index or peak VO2.
