Cardiac arrest & resuscitation
Obesity and nutrition risk in patients admitted to intensive care after cardiac arrest: A multicentre cohort study
Authors' conclusion
Among resuscitated cardiac arrest patients admitted to ICU, high nutrition risk is prevalent regardless of obesity status and is associated with poorer outcomes in-hospital and up to one year.
