[Advances in the epidemiology of chronic thromboembolic pulmonary hypertension].

The early symptoms of chronic thromboembolic pulmonary hypertension (CTEPH) are not specific, and there is a high rate of misdiagnosis, missed diagnosis, and lack of awareness among clinicians. Understanding the current epidemiological characteristics of CTEPH is helpful to raise the understanding level of Chinese clinicians on CTEPH and improve the current status of prevention and treatment. However, epidemiological information and relevant reviews on CTEPH are currently lacking in China. In this review, we combined the published epidemiological literature on CTEPH in the real world, summarized the research overview, prevalence, incidence, survival rate and risk factors of CTEPH, and provided an outlook for the development of multicenter and high-quality CTEPH epidemiological research in China.
