Background: The aim of this study was to analyze the gender factors associated with good or bad prognosis after return of spontaneous circulation after out-of hospital cardiac arrest.
Methods: The patients admitted to the intensive care unit after successful resuscitation after out-of hospital cardiac arrest were retrospectively identified and evaluated. Thirty days mortality after admission, and neurologic outcome at 6 months after hospital discharge (cerebral performance category [CPC]) were evaluated.
Results: One hundred forty-two patients were evaluated in this study; there were 101 males (71.1%). The median age was 52 years old (43-63). Thirty days after admission, 85 patients (59.9%) survived, 40 patients had a good neurologic outcome (CPC 1-2). The factors associated 30 days mortality were cause of arrest (non-cardiac, p = 0.03), lactate in emergency department (p = 0.05) and the factors associated with good neurologic outcome were males (p = 0.007), young age (p = 0.01), body weight and height (p = 0.001), cause of death (cardiac, p = 0.000). Alcohols and smoking were not associated with mortality and neurologic outcome. In multiple logistic regression analysis, men had a 8-fold increased good neurologic outcome (CPC 1-2) (odds ratio [OR] 8.038, 95% Confidence Interval [CI] 1.079-59.903). Other factors associated with good neurologic outcome were cardiac cause of death (OR 5.523, 95% CI 1.562-19.533) and young age (OR 1.055, 95% CI 1.009-1.103).
Conclusions: Men had a good neurologic outcome after return of spontaneous circulation after out-of hospital cardiac arrest in one emergency center. Other additional factors including gonadal hormones should be evaluated.
