title: Five-year survival of patients after out-of-hospital cardiac arrest depending on age.
abstract: Patient's age belongs to the independent prognostic factors of patients after out-of-hospital cardiac arrest (OHCA). This study aimed to evaluate the influence of age on 5-year survival in professionally cardio-pulmonary resuscitated patients with "primary cardiac" etiology OHCA. In this analysis of prospective multi-centric study, from April 1, 2002 until August 31, 2004, a total of 560 patients were included (aged 16-97 years) from the East Bohemian region, for whom a professional cardio-pulmonary resuscitation for OHCA was attempted. In the age subgroup <70 years there were 307 patients and in the age subgroup ≥ 70 years there were 253 patients. Of the subgroup <70 years, 29 patients (10%) survived to year 5 (58% from the 50 patients surviving to day 30), and in the subgroup ≥ 70 years, we had 4 patients surviving to year 5 (2%) (29% from the 14 patients surviving to day 30), respectively (Fisher's exact test; comparison in the all resuscitated patients: p < 0.001, in the population surviving to day 30: p = 0.071). In conclusion, there was a trend towards a worse outcome in 5-year survival following OHCA in the patients aged ≥ 70 years. Nevertheless, these data support that prognosis OHCA of elders is not associated with universal dismal outcome.
