CONTEXT AND OBJECTIVE: @entity1167 is a common occurrence, and even with efficient emergency treatment, it is associated with a poor prognosis. Identification of predictors of survival after cardiopulmonary resuscitation may provide important information for the healthcare team and family. The aim of this study was to identify factors associated with the survival of @entity1 treated for @entity1167 , after a one-year follow-up period. DESIGN AND SETTING: Prospective cohort study conducted in the emergency department of a Brazilian university hospital. METHODS: The inclusion criterion was that the @entity1 presented @entity1167 that was treated in the emergency department (n = 285). Data were collected using the In-hospital Utstein Style template. @entity797 regression was used to determine which variables were associated with the survival rate (with 95% significance level). RESULTS: After one year, the survival rate was low. Among the @entity1 treated, 39.6% experienced a return of spontaneous circulation; 18.6% survived for 24 hours and of these, 5.6% were discharged and 4.5% were alive after one year of follow-up. @entity1 with pulseless electrical activity were half as likely to survive as @entity1 with @entity2224 . For @entity1 with @entity1167 , the survival rate was 3.5 times lower than that of @entity1 with pulseless electrical activity. CONCLUSIONS: The initial cardiac rhythm was the best predictor of @entity1 survival. Compared with @entity2224 , pulseless electrical activity was associated with shorter survival times. In turn, compared with pulseless electrical activity, @entity1167 was associated with an even lower survival rate.
