An observational study of The Geodemographics of CTEPH in Taiwan, run by National Taiwan University Hospital at 1 site in Taiwan.
Trial summary
The diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) is difficult for numerous reasons and is related with a poor prognosis. In Taiwan, the incidence of CTEPH and its clinical features are unknown. Read more about this study
