Survival after out-of-hospital cardiac arrest has increased during the last decade in Denmark. We aimed to study impact of age on changes survival and whether it was possible identify patients with minimal chance 30-day survival.Using data from nationwide Danish Cardiac Arrest Registry (2001─2011), we identified 21 480 ≥18 years old a presumed cardiac-caused for which resuscitation attempted. Patients were divided into 3 preselected age-groups: working-age 18 65 (33.7%), early senior 66 80 (41.5%), late >80 (24.8%). Characteristics patients, as follows: witnessed 53.8%, 51.1%, 52.1%; bystander cardiopulmonary 44.7%, 30.3%, 23.4%; prehospital shock defibrillator 54.7%, 45.0%, 33.8% (all P<0.05). Between 2001 2011, return spontaneous circulation hospital arrival increased: 12.1% 34.6%; 6.4% 21.5%; 4.0% 15.0% P<0.001). Furthermore, 5.8% 22.0% (P<0.001); 2.7% 8.4% (P<0.001), whereas experienced only minor increase (1.5% 2.0%; P=0.01). Overall, 9499 achieved if they met 2 criteria: had not received defibrillator.All groups large temporal arrival, but most prominent young. With use criteria, survival.
