Thus, we investigated the early outcomes in these patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>Patients with type A AAD who were transported to hospitals belonging to the Tokyo Acute Aortic Super-network between January 2015 and December 2019 were considered for this study. We assessed the early mortality of these patients presenting with CPA and also investigated the differences in outcomes between patients with out-of-hospital and in-hospital CPA.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>A total of 3307 patients with type A AAD were transported, 434 (13.1%) of whom presented with CPA. The overall mortality of patients presenting with CPA was 88.2% (383\/434), of which 94.5% (240\/254) experienced out-of-hospital CPA and 79.4% (143\/180) experienced in-hospital CPA (P\u2009&amp;lt;\u20090.001). Multivariable analysis revealed that aortic surgery [odds ratio (OR), 0.022; 95% confidence interval (CI), 0.008\u20130.060; P\u2009&amp;lt;\u20090.001] and patient age over 80\u2009years (OR, 2.946; 95% CI, 1.012\u20138.572; P\u2009=\u20090.047) were related with mortality in patients with type A AAD and CPA. Between in-hospital and out-of-hospital CPA, the proportions of DeBakey type 1 (OR, 2.32; 95% CI, 1.065\u20135.054; P\u2009=\u20090.034), cerebral malperfusion (OR, 0.188; 95% CI, 0.056\u20130.629; P\u2009=\u20090.007), aortic surgery (OR, 0.111; 95% CI, 0.045\u20130.271; P\u2009=\u20090.001), age (OR, 0.969; 95% CI, 0.940\u20130.998; P\u2009=\u20090.039) and the time from symptom onset to hospital admission (OR, 1.122; 95% CI, 1.025\u20131.228; P\u2009=\u20090.012) were significantly different.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>Patients with type A AAD presenting with CPA exhibited extremely high rates of death. Patient outcomes following in-hospital CPA tended to be better than those following out-of-hospital CPA; however, this difference was not significantly different. To prevent deaths, aortic surgery, when possible, should be considered in patients with type A AAD who sustained CPA.<\/jats:p><\/jats:sec>","DOI":"10.1093\/ejcts\/ezad056","type":"journal-article","created":{"date-parts":[[2023,2,20]],"date-time":"2023-02-20T13:57:15Z","timestamp":1676901435000},"source":"Crossref","is-referenced-by-count":14,"title":["Outcomes of type A acute aortic dissection with cardiopulmonary arrest: Tokyo Acute Aortic Super-network Registry"],"prefix":"10.1093","volume":"63","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6396-0437","authenticated-orcid":false,"given":"Manabu","family":"Yamasaki","sequence":"first","affiliation":[{"name":"Tokyo, Cardiovascular Care Unit Network Scientific Committee , Tokyo, Japan"},{"name":"Department of Cardiovascular Surgery, St. Luke's International Hospital , Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4976-4055","authenticated-orcid":false,"given":"Hideaki","family":"Yoshino","sequence":"additional","affiliation":[{"name":"Tokyo, Cardiovascular Care Unit Network Scientific Committee , Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6903-6501","authenticated-orcid":false,"given":"Takashi","family":"Kunihara","sequence":"additional","affiliation":[{"name":"Tokyo, Cardiovascular Care Unit Network Scientific Committee , Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koichi","family":"Akutsu","sequence":"additional","affiliation":[{"name":"Tokyo, Cardiovascular Care Unit Network Scientific Committee , Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomoki","family":"Shimokawa","sequence":"additional","affiliation":[{"name":"Tokyo, Cardiovascular Care Unit Network Scientific Committee , Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hitoshi","family":"Ogino","sequence":"additional","affiliation":[{"name":"Tokyo, Cardiovascular Care Unit Network Scientific Committee , Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitsuhiro","family":"Kawata","sequence":"additional","affiliation":[{"name":"Tokyo, Cardiovascular Care Unit Network Scientific Committee , Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshiyuki","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Tokyo, Cardiovascular Care Unit Network Scientific Committee , Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6588-3305","authenticated-orcid":false,"given":"Michio","family":"Usui","sequence":"additional","affiliation":[{"name":"Tokyo, Cardiovascular Care Unit Network Scientific Committee , Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuhiro","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Tokyo, Cardiovascular Care Unit Network Scientific Committee , Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeshiro","family":"Fujii","sequence":"additional","affiliation":[{"name":"Tokyo, Cardiovascular Care Unit Network Scientific Committee , Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takeshi","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Tokyo, Cardiovascular Care Unit Network Scientific Committee , Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ken","family":"Nagao","sequence":"additional","affiliation":[{"name":"Tokyo, Cardiovascular Care Unit Network Scientific Committee , Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Morimasa","family":"Takayama","sequence":"additional","affiliation":[{"name":"Tokyo, Cardiovascular Care Unit Network Scientific Committee , Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2023,2,20]]},"reference":[{"key":"2023041022074141000_","doi-asserted-by":"crossref","first-page":"957","DOI":"10.1093\/ejcts\/ezab146","article-title":"Risk analysis for early mortality in emergency acute type A aortic dissection surgery: experience of Tokyo Acute Aortic Super-network","volume":"60","author":"Yamasaki","year":"2021","journal-title":"Eur J Cardiothorac Surg"},{"key":"2023041022074141000_","first-page":"1748","article-title":"Tokyo CCU Network and Tokyo Acute Aortic Super Network","volume":"34","author":"Akutsu","year":"2019","journal-title":"Is Systolic Blood Pressure High in Patients with Acute Aortic Dissection on First Medical Contact before Hospital Transfer?
