OBJECTIVE: We examined the effects of sex on @entity1167 outcomes. There is evidence that @entity1 are more likely to survive @entity1167 than @entity1 . However, few large studies have examined these sex differences in detail. It is unknown whether the female survival advantage is age-specific or whether sex affects neurologic outcomes after @entity1167 events. METHODS: Data were analyzed from a nationwide population-based @entity1167 database (between January 2005 and December 2007) involving 318,123 @entity1 (male: 188,357, female: 129,766) to assess the effects of sex on @entity1167 outcomes in Japan. We selected 276,590 @entity1 aged 20 to 89 years with @entity1167 and compared the frequencies of initial cardiac rhythms, 1-month survival rates, and favorable neurologic outcome rates between sexes. RESULTS: The incidence of @entity1167 was higher in @entity1 than in @entity1 ( @entity1 : 0.12%; @entity1 : 0.07%). @entity1 were witnessed more often while @entity1167 was occurring ( @entity1 : 42.1% and @entity1 : 36.9%), typically presented with @entity2224 / @entity1165 rhythms, and had a higher 1-month survival rate overall after @entity1167 events ( @entity1 : 5.2% and @entity1 : 4.3%). However, the rate of survival with a favorable neurologic outcome for @entity1 aged 30 to 49 years was significantly higher than that for @entity1 within the same age range. Among @entity1 initially presenting with @entity2224 / @entity1165 , the rate of survival with favorable neurologic outcome was higher for @entity1 than @entity1 in the group aged 40 to 59 years. CONCLUSION: Our results suggest that @entity1 have a higher 1-month survival rate after @entity1167 because of a higher frequency of @entity2224 / @entity1165 compared with @entity1 . Although @entity1 of both sexes with @entity1167 initially presenting with @entity2224 / @entity1165 exhibited similar overall survival rates, the rate of survival with favorable neurologic outcome was significantly higher for @entity1 than @entity1 in the group aged 40 to 59 years.
