The overall chance of survival among those who have cardiac arrest outside hospital is poor, at 10%. Among those who have an out-of-hospital cardiac arrest, 70% occur at home and their survival rate is 6%. For those who have an in-hospital cardiac arrest, the survival rate one year from at least the occurrence of cardiac arrest is estimated to be 13%. One year survival is estimated to be higher in people with cardiac admission diagnoses (39%), when compared to those with non-cardiac admission diagnoses (11%). Among children rates of survival are 3 to 16% in North America. For in hospital cardiac arrest survival to discharge is around 22%. Those who survive to Return-of-Spontaneous-Circulation (ROSC) and hospital admission frequently present with Post-Cardiac Arrest Syndrome which usually presents with neurological injury that can range from mild memory problems to coma. Hypoxic ischemic brain injury is the most detrimental outcome for people suffering a cardiac arrest. Poor neurological outcomes following cardiac arrest are much more prevalent in countries that do not use withdrawal of life support (~50%) as compared to those that do (less than 10%). Most improvements in cognition occur during the first three months following cardiac arrest, with some individuals reporting improvement up to one-year post cardiac arrest. 50 – 70% of cardiac arrest survivors report fatigue as a symptom, making fatigue the most prevalent patient-reported symptom. Prognosis is typically assessed 72 hours or more after cardiac arrest. Rates of survival are better in those who someone saw collapse, got bystander CPR, or had either ventricular<unk>  or ventricular fibrillation when assessed. Survival among those with Vfib or Vtach is 15 to 23%. Women are more likely to survive cardiac arrest and leave hospital than men. A 1997 review found rates of survival to discharge of 14% although different studies varied from 0 to 28%. In those over the age of 70 who have a cardiac arrest while in hospital, survival to hospital discharge is less than 20%. How well these individuals are able to manage after leaving hospital is not clear. The global rate of people who were able to recover from out-of-hospital cardiac arrest after receiving CPR has been found to be approximately 30%, and the rate of survival to discharge from the hospital has been estimated at 9%. Survival to discharge from the hospital is more likely among people whose cardiac arrest was witnessed by a bystander or emergency medical services, who received bystander CPR and among those living in Europe and North America. Relatively lower survival to hospital discharge rates have been observed in Asian countries.
