The distribution of the blood phenotypes was similar between AAA patients and the Portuguese population. The median follow-up time was 75.4 months (interquartile range 65.8\u201381.6). Patient survival rates at 1 and 5 years were 89.3% (95% Confidence Interval 86.0\u201392.7) and 61.9% (56.2\u201368.2), respectively. MACE-free survival at 1 and 5 years was 85.7% (81.9\u201389.5) and 57.6% (51.9\u201364.0), respectively. Survival and MACE-free survival rates were similar across blood group types. Age, maximum aortic diameter, peripheral arterial disease and chronic obstructive pulmonary disease were independent predictors of mortality. Maximum aortic diameter, estimated glomerular filtration rate, cerebrovascular disease and type of surgery were independent predictors of MACE.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>We found no association between the blood types and the prevalence of AAA or adverse outcomes following AAA repair.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/17085381251360121","type":"journal-article","created":{"date-parts":[[2025,7,18]],"date-time":"2025-07-18T08:45:34Z","timestamp":1752828334000},"page":"290-298","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["ABO-blood groups and outcomes after abdominal aortic aneurysm repair"],"prefix":"10.1177","volume":"34","author":[{"given":"Teresa","family":"Machado","sequence":"first","affiliation":[{"name":"University of Porto"}]},{"given":"F\u00e1bio","family":"Sousa-Nunes","sequence":"additional","affiliation":[{"name":"Vila Nova de Gaia\/Espinho Hospital Center"},{"name":"University of Porto"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2656-8935","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Rocha-Neves","sequence":"additional","affiliation":[{"name":"University of Porto"}]},{"given":"In\u00eas","family":"Machado","sequence":"additional","affiliation":[{"name":"S\u00e3o Jo\u00e3o University Hospital Center"}]},{"given":"Jos\u00e9 Fernando","family":"Teixeira","sequence":"additional","affiliation":[{"name":"S\u00e3o Jo\u00e3o University Hospital Center"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5705-0509","authenticated-orcid":false,"given":"Pedro","family":"Videira-Reis","sequence":"additional","affiliation":[{"name":"University of Porto"},{"name":"S\u00e3o Jo\u00e3o University Hospital Center"}]},{"given":"Marina","family":"Dias-Neto","sequence":"additional","affiliation":[{"name":"University of Porto"},{"name":"S\u00e3o Jo\u00e3o University Hospital Center"}]}],"member":"179","published-online":{"date-parts":[[2025,7,18]]},"reference":[{"key":"e_1_3_5_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2013.11.007"},{"key":"e_1_3_5_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.111.030379"},{"key":"e_1_3_5_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2018.09.020"},{"key":"e_1_3_5_5_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41572-018-0030-7"},{"key":"e_1_3_5_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.atherosclerosis.2016.05.049"},{"key":"e_1_3_5_7_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.115.017563"},{"key":"e_1_3_5_8_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-0032-1315758"},{"key":"e_1_3_5_9_2","doi-asserted-by":"publisher","DOI":"10.1038\/srep23250"},{"key":"e_1_3_5_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2015.05.043"},{"key":"e_1_3_5_11_2","doi-asserted-by":"publisher","DOI":"10.1161\/ATVBAHA.112.248757"},{"key":"e_1_3_5_12_2","first-page":"49","article-title":"ABO blood group and vascular disease: an update","volume":"40","author":"Dentali F","year":"2014","unstructured":"Dentali F, Sironi AP, Ageno W, et al.
