Outcomes after out-of-hospital cardiac arrest in immigrants vs natives in Denmark

Similar OCHA management resulted in similar outcomes in immigrants vs non-immigrants. CAG, coronary angiography; PCI, percutaneous coronary intervention. [Display omitted] Ethnic disparities subsist in out-of-hospital cardiac arrest (OHCA) outcomes in the US, yet it is unresolved whether similar inequalities exist in European countries. This study compared survival after OHCA and its determinants in immigrants and non-immigrants in Denmark. Using the nationwide Danish Cardiac Arrest Register, 37,622 OHCAs of presumed cardiac cause between 2001 and 2019 were included, 95% in non-immigrants and 5% in immigrants. Univariate and multiple logistic regression was used to assess disparities in treatments, return of spontaneous circulation (ROSC) at hospital arrival, and 30-day survival. Immigrants were younger at OHCA (median 64 [IQR 53–72] vs 68 [59–74] years; p
