摘要慢性血栓栓塞性肺动脉高压（chronic thromboembolic pulmonary hypertension，CTEPH）早期症状缺乏特异性，存在误诊、漏诊率高和临床医生对其认识不足等问题。了解CTEPH目前的流行病学特点，有助于提高我国临床医师对CTEPH的认识水平，改善防治现状。但目前国内关于CTEPH流行病学数据以及相关综述尚缺乏。本文结合国内外CTEPH现实世界研究已发表的流行病学有关文献，分别从CTEPH研究概况、患病率、发病率、生存率及危险因素进行综述，并对未来我国开展全国多中心、高质量的CTEPH流行病学研究进行展望。

abstractsThe 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.
