Cardiac arrest & resuscitation
Aetiology of in-hospital cardiac arrest and long-term survival after the first 30 days: insights from the Swedish registry for cardiopulmonary resuscitation
Authors' conclusion
Aetiology of in-hospital cardiac arrest is independently associated with long-term prognosis after 30-day survival. Compared with myocardial ischemia, infectious, haemorrhagic and pulmonary causes are associated with higher long-term mortality.
