Similar findings were observed in the propensity-score matching and sensitivity analysis only including hyperacute TBAD patients. A novel prediction model was established based on the aforementioned parameters. The new model showed significantly improved discriminant ability compared with the previously established model (c-index 0.78 [95% CI 0.71\u20130.85] vs. 0.67 [95% CI 0.58\u20130.75], <jats:italic>p<\/jats:italic> = .03), driven by increased reclassification ability in identifying TBAD patients (NRI for events 0.16, 95% CI 0.02\u20130.30, <jats:italic>p<\/jats:italic> = .02).<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> Morphological predictors, including the degree of question mark, aortic width, aortic root diameter, brachiocephalic trunk angle, and brachiocephalic trunk diameter, may be used to identify patients at high risk of TBAD.<\/jats:p>","DOI":"10.3389\/fphys.2023.1065805","type":"journal-article","created":{"date-parts":[[2023,2,2]],"date-time":"2023-02-02T06:40:39Z","timestamp":1675320039000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Identification of high-risk patients for development of type B aortic dissection based on novel morphological parameters"],"prefix":"10.3389","volume":"14","author":[{"given":"Da","family":"Li","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiarong","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jichun","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tiehao","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiangguo","family":"Zeng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tinghui","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ding","family":"Yuan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2023,2,2]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1654","DOI":"10.1038\/s41591-020-1009-y","article-title":"A population-based phenome-wide association study of cardiac and aortic structure and function","volume":"26","author":"Bai","year":"2020","journal-title":"Nat.
