Retrospective study finds that body measurements affect survival after cardiac arrest, suggesting personalized CPR approaches.

The study aims to assess the relationship between thoracic body measurements and survival rates after in-hospital cardiac arrest.
Retrospective cohort analysis of 431 adults with in-hospital cardiac arrest and available chest CT.
Measured body mass index (BMI), internal anteroposterior diameter (IAPD), and external anteroposterior diameter (EAPD).
Utilized multivariable logistic regression to evaluate time-dependent mortality associations based on CPR duration.
Overall survival at 28 days was 40.8% (176/431).
In the first 5 minutes of CPR, higher BMI, IAPD, and EAPD correlated with increased mortality, while underweight patients showed lower mortality.
After 10 minutes, anatomical associations diminished, with CPR duration being the major factor impacting outcomes.

Kim et al. (2026) studied this question.
