Gender association with incidence, clinical profile, and outcome of out-of-hospital cardiac arrest: A middle east perspective

Background: Out-of-hospital cardiac arrest (OHCA) is a leading cause of death worldwide. However, there is limited information on the outcome of the OHCA in the Middle East population, and limited studies have been carried out in the Arab Gulf countries. Hence, we aim to study the incidence and rate of survival in the OHCA setting and to assess the impact of gender on the clinical outcome following OHCA. Methods: Retrospective analysis of a prospective registry of all eligible, consecutive, and nontraumatic adult patients who successfully resuscitated (return of spontaneous circulation) from "Cardiac Arrest" occurring outside the hospital, Hospitalized in Doha, Qatar from January 1991 to June 2010. Results: A total of 41,453 consecutive patients were admitted during the study, of whom 987 (2.4%) had a diagnosis of OHCA. Among them, 269 (27.3%) were women and 718 (72.7%) were men. Although the mortality rate was higher in females than in males (65.4% vs. 57.7%, P = 0.03), the logistic regression analysis did not show gender as an independent predictor of death in this clinical setting. Conclusion: In this sample of the state population, women who have OHCAs had a lower rate of survival, but gender was not an independent predictor of mortality following OHCA.
