Cardiogenic shock after out\u2010of\u2010hospital cardiac arrest (OHCA) can be due to transient myocardial stunning but also reflect the increasing severity of ongoing heart failure. The Society for Cardiovascular Angiography and Interventions (SCAI) proposed a division of cardiogenic shock into 5 phenotypes, with cardiac arrest being a modifier. The objective was to apply SCAI shock classification to a well\u2010characterized OHCA population and describe the hemodynamic characteristics and prognostic significance of increasing SCAI classes.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Methods and Results<\/jats:title>\n            <jats:p xml:lang=\"en\">\n              This is a post hoc analysis of data from the BOX (Blood Pressure and Oxygenation Targets in Post Resuscitation Care) trial of comatose patients with OHCA. Patients were classified according to SCAI class upon hospital admission. Invasive arterial and pulmonary arterial measurements were obtained the first 72\u2009hours after admission, and perfusion pressure, cardiac index and cardiac power output were calculated. Of 789 patients included, 31.6% were classified as SCAI class B\/C, 29.9% as SCAI class D, and 38.5% as SCAI class E. The first recorded perfusion pressure differed between SCAI class B\/C, D, and E being lower in higher SCAI classes. The difference was found only at the first measurement. Cardiac index and cardiac power output did not differ at any time point between classes. The 1\u2010year mortality rate increased with SCAI Class B\/C to E (21.3%, 34.3%, and 48.4%, respectively;\n              <jats:italic>P<\/jats:italic>\n              &lt;0.001).\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p xml:lang=\"en\">The 1\u2010year mortality rate after OHCA increased with increasing SCAI classes, but cardiac index, cardiac power output, and perfusion pressure remained notably similar in the first 72\u2009hours after admission. This challenges whether all OHCAs should be recorded as SCAI class E by default.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Registration<\/jats:title>\n            <jats:p xml:lang=\"en\">\n              URL:\n              <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/www.clinicaltrials.gov\">https:\/\/www.clinicaltrials.gov<\/jats:ext-link>\n              ; Unique identifier: NCT03141099.\n            <\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/jaha.124.036659","type":"journal-article","created":{"date-parts":[[2024,12,20]],"date-time":"2024-12-20T11:22:16Z","timestamp":1734693736000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":10,"title":["Hemodynamic Characteristics and Prognostic Implication of Modified Society for Cardiovascular Angiography and Interventions Shock Classification in Comatose Patients With Out\u2010of\u2010Hospital Cardiac Arrest"],"prefix":"10.1161","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7757-2571","authenticated-orcid":false,"given":"Louise","family":"Linde","sequence":"first","affiliation":[{"name":"Department of Cardiology Odense University Hospital Odense Denmark"},{"name":"Department of Clinical Research University of Southern Denmark Odense Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5880-3733","authenticated-orcid":false,"given":"Rasmus P.","family":"Beske","sequence":"additional","affiliation":[{"name":"Department of Cardiology Copenhagen University Hospital Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin A.
