The treatment of CTEPH could be balloon pulmonary angioplasty (BPA), medical (MT) or pulmonary endarterectomy (PEA). This study aims to assess the clinical characteristics of CTEPH patients, surgically or medically treated, in a pulmonology referral center. Materials and Methods: A total of 124 patients with PH with suspected CTEPH (53 male subjects and 71 female subjects; mean age at diagnosis 67 \u00b1 6) were asked to give informed consent and then were evaluated. The presence of CTEPH was ascertained by medical evaluations, radiology and laboratory tests. Results: After the evaluation of all clinical data, 65 patients met the inclusion criteria for CTEPH and they were therefore enrolled (22 males and 43 females; mean age at diagnosis was 69 \u00b1 8). 26 CTEPH patients were treated with PEA, 32 with MT and 7 with BPA. There was a statistically significant age difference between the PEA and MT groups, at the time of diagnosis, the PEA patients were younger than the MT patients, whereas there was no statistically significant difference in other clinical characteristics (e.g., smoking habit, thrombophilia predisposition), as well as functional and hemodynamic parameters (e.g., 6-min walk test, right heart catheterization). During three years of follow-up, no patients in the PEA groups died; conversely, eleven patients in the MT group died during the same period (p &lt; 0.05). Furthermore, a significant decrease in plasma BNP values and an increase in a meter at the six-minute walk test, 1 and 3 years after surgery, were observed in the PEA group (p &lt; 0.05). Conclusions: This study seems to confirm that pulmonary endarterectomy (PEA) can provide an improvement in functional tests in CTEPH.<\/jats:p>","DOI":"10.3390\/medicina58081094","type":"journal-article","created":{"date-parts":[[2022,8,15]],"date-time":"2022-08-15T03:33:20Z","timestamp":1660534400000},"page":"1094","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Chronic Thromboembolic Pulmonary Hypertension: An Observational Study"],"prefix":"10.3390","volume":"58","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8990-859X","authenticated-orcid":false,"given":"Barbara","family":"Ruaro","sequence":"first","affiliation":[{"name":"Department of Pulmonology, University Hospital of Cattinara, University of Trieste, 34149 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7284-5016","authenticated-orcid":false,"given":"Paola","family":"Confalonieri","sequence":"additional","affiliation":[{"name":"Department of Pulmonology, University Hospital of Cattinara, University of Trieste, 34149 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gaetano","family":"Caforio","sequence":"additional","affiliation":[{"name":"Department of Pulmonology, University Hospital of Cattinara, University of Trieste, 34149 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1061-9507","authenticated-orcid":false,"given":"Elisa","family":"Baratella","sequence":"additional","affiliation":[{"name":"Department of Radiology, Cattinara Hospital, University of Trieste, 34149 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Riccardo","family":"Pozzan","sequence":"additional","affiliation":[{"name":"Department of Pulmonology, University Hospital of Cattinara, University of Trieste, 34149 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefano","family":"Tavano","sequence":"additional","affiliation":[{"name":"Department of Pulmonology, University Hospital of Cattinara, University of Trieste, 34149 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiara","family":"Bozzi","sequence":"additional","affiliation":[{"name":"Department of Pulmonology, University Hospital of Cattinara, University of Trieste, 34149 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Selene","family":"Lerda","sequence":"additional","affiliation":[{"name":"24ore Business School, Via Monte Rosa, 91, 20149 Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pietro","family":"Geri","sequence":"additional","affiliation":[{"name":"Department of Pulmonology, University Hospital of Cattinara, University of Trieste, 34149 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco","family":"Biolo","sequence":"additional","affiliation":[{"name":"Department of Pulmonology, University Hospital of Cattinara, University of Trieste, 34149 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maurizio","family":"Cortale","sequence":"additional","affiliation":[{"name":"Department of Medical, Surgical, & Health Sciences, Cattinara Hospital, University of Trieste, 34127 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4791-768X","authenticated-orcid":false,"given":"Marco","family":"Confalonieri","sequence":"additional","affiliation":[{"name":"Department of Pulmonology, University Hospital of Cattinara, University of Trieste, 34149 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0864-9766","authenticated-orcid":false,"given":"Francesco","family":"Salton","sequence":"additional","affiliation":[{"name":"Department of Pulmonology, University Hospital of Cattinara, University of Trieste, 34149 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"711","DOI":"10.1097\/HCO.0000000000000907","article-title":"Chronic thromboembolic pulmonary hypertension anno 2021","volume":"36","author":"Nossent","year":"2021","journal-title":"Curr.
