Key result
ICU admission BMI fails to predict in-hospital mortality in sudden cardiac arrest survivors.
Why the study?
Nutritional status influences mortality in post-cardiac-arrest patients, but sex differences in the prognostic impact of ICU-admission BMI on in-hospital mortality remained unclear.
Does BMI on admission to the ICU predict in-hospital mortality in male or female sudden cardiac arrest survivors?
Observational (n=129)
No
Does BMI on admission to the ICU predict in-hospital mortality in male or female sudden cardiac arrest survivors?
BMI on admission to the ICU does not appear to be a significant predictor of in-hospital mortality for either male or female survivors of sudden cardiac arrest.
BACKGROUND: A number of factors influence mortality in post-cardiac-arrest (CA) patients, nutritional status being one of them. The aim of this study was to assess whether there are sex differences in the prognostic impact of BMI, as calculated on admission to an intensive care unit, on in-hospital mortality in sudden cardiac arrest (SCA) survivors. METHODS: We carried out a retrospective analysis of data of 129 post-cardiac-arrest patients with return of spontaneous circulation (ROSC) admitted to the Intensive Care Unit (ICU) of the University Teaching Hospital in Wrocław between 2017 and 2022. RESULTS: Female patients were significantly older than male patients (68.62 ± 14.77 vs. 62.7 ± 13.95). The results of univariable logistic regression analysis showed that BMI was not associated with the odds of in-hospital death in either male or female patients. In an age-adjusted model, age was an independent predictor of the odds of in-hospital death only in male patients (OR = 1.034). In our final multiple logistic regression model, adjusted for the remaining variables, none of the traits analysed were a significant independent predictor of the odds of in-hospital death in female patients, whereas an initial rhythm of ventricular fibrillation or pulseless ventricular tachycardia (VF/pVT) was an independent predictor of the odds of in-hospital death in male patients (OR = 0.247). CONCLUSIONS: BMI on admission to ICU is not a predictor of the odds of in-hospital death in either male or female SCA survivors.

Czapla et al. (2023) conducted an observational in Post-cardiac-arrest (n=129). Body Mass Index (BMI) was evaluated on In-hospital mortality. Body Mass Index on admission to the ICU was not a significant predictor of in-hospital mortality in either male or female sudden cardiac arrest survivors.
