Objective: Cardiopulmonary resuscitation (CPR) has been known in its present form since 1960. Different studies have reported variable outcomes among different countries. Therefore, the purpose of this study was to assess the rate of CPR success and the survival rate in managing cardiac arrest among patients in an educational medical center.

Methods: This cross-sectional study was performed at Imam Hosein hospital, Tehran, Iran. All patients, admitted to the emergency department with cardiac arrest between March 2007 and January 2008 were included. We used a formerly designed registration form and hospital documentation to retrieve the data of included patients. The main outcomes were the rate of CPR success and the survival rate of these patients.

Results: Totally 855 patients were included, from which 510 (59.64%) were males. The mean age of included patients was 63 ± 17.6. The CPR process was successful among 364 (42.58%) patients. A total number of 101 (11.82%) patients were discharged from the hospital. Different factors as the cause of cardiac arrest and past medical problems affected the probability of CPR success and the survival of patients with cardiac arrest.

Conclusion: Survival rate at hospital discharge was less than one-third of patients and nearly half of the patients received successful CPR. More intensive care unit (ICU) facilities and educational interventions for the emergency staff and the community can enhance the survival of cardiac arrest patients in our health system.
