Goto T, et al. - In this single-centre retrospective cohort study, the researchers investigated the impact of age on outcomes among patients who had out-of-hospital cardiac arrest (OHCA) treated with extracorporeal cardiopulmonary resuscitation (ECPR). This retrospective analysis of medical records from a single centre in Japan was directed at Osaka Saiseikai Senri Hospital, a critical care centre approved by the Ministry of Health, Labour and Welfare and located in the northern city of Suita, Osaka, Japan. Participants were patients who had consecutive OHCA aged ≥18 years who underwent ECPR from 2005 to 2013. It was observed in the findings that advanced age was associated with the lower rate of 1-month survival in patients who had OHCA who underwent ECPR. Results of this study suggested that ECPR could not be useful for patients who had OHCA aged ≥70 years.
