Good neurological outcomes (CPC 1 and 2) were observed in 13 % (144/1128) of patients. The main suspected cause of cardiac arrest was cardiac origin (54 %, 608/1128), followed by hypoxia (11 %, 127/1128). Survivors were significantly younger (60 vs 71 years, <em>p</em> &lt; 0.001), were less disabled (<em>p</em> &lt; 0.001), had a higher incidence of witnessed cardiac arrest (80 % vs 69 %, <em>p</em> = 0.018), received more often bystander cardiopulmonary resuscitation (CPR, 62 % vs 47 %, <em>p</em> = 0.003) or Dispatcher Assisted-CPR (44 % vs 32 %, <em>p</em> = 0.004). Moreover, patients who survived at least 30 days had a higher incidence of shockable initial rhythm (57 % vs 24 %, <em>p</em> &lt; 0.001).</div><div><strong>Conclusions</strong> Patients who survived at least 30 days were younger and male, had less disability, a shockable initial rhythm, and a cardiac arrest in public.</div></div>","PeriodicalId":55064,"journal":{"name":"Heart & Lung","volume":"73 ","pages":"Pages 1-8"},"PeriodicalIF":2.4,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143845147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
