Age is related to neurological outcome in patients with out-of-hospital cardiac arrest (OHCA) receiving therapeutic hypothermia (TH)

In this study, we retrospectively reviewed the patients' outcomes after cardiac arrest based on age in one center, to determine whether geriatric patients had worse outcomes. This was a single-center, retrospective cohort study. The patients admitted to the intensive care unit on successful resuscitation after OHCA were retrospectively identified and evaluated. This was a retrospective cohort study of patients over 18years of-age with return of spontaneous circulation (ROSC) (>24h) after cardiac arrest who were admitted to the emergency intensive care unit (EICU) and received post-cardiac arrest care between March 2007 and December 2013. Finally, a total of 295 patients were enrolled during the study period; of these, 79 patients (36.6%) had a good cerebral performance category (CPC). In stepwise multivariate analysis, young age (per 10years) (odds ratio [OR] 1.42, 95% CI 1.00–1.99, p=0.044), high hemoglobin level (per 1g/dL) (OR 1.31, 95% CI 1.07–1.60, p=0.008), non-diabetic patients (OR 15.21, 95% CI 1.85–125.3, p=0.01), cardiogenic cardiac arrest (OR 8.68, 95% CI 3.72–20.30, p
