[Why do we need cardiac arrest centers?].

In patients with out-of-hospital cardiac arrest (OHCA) and return of spontaneous circulation (ROSC) following cardiopulmonary resuscitation (CPR), the prognosis is influenced by various factors. In the prehospital setting, the duration of ischemia from the time of onset of cardiac arrest to the beginning of effective resuscitation measures is by far the most critical and determining factor for outcome. This interval can be shortened by an increase in the rate of lay CPR measures. With respect to intrahospital follow-up care, a number of structural factors have a relevant influence on prognosis. According to the literature, case volume, size of the hospital and the number of post-OHCA patients treated per year also have a large influence on the further prognosis. The crucial factor here is the availability and permanent readiness of a catheterization laboratory with the possibility of an immediate coronary intervention. In OHCA patients with ST-segment elevation myocardial infarction (STEMI), the time passed until the reopening of the occluded infarcted vessel is of paramount importance for survival. The 24/7 around the clock availability of a catheterization laboratory is therefore one of the indispensable prerequisites for a cardiac arrest center (CAC). In addition, a number of technical, structural, and organizational arrangements must be implemented in the CAC clinics in order to fulfil the requirements for such a center. The certification of CACs is currently being implemented by the German Resuscitation Council (GRC) and the German Society of Cardiology (DGK). As an important aim the GRC and the medical societies involved are hoping to avoid misallocation of post-OHCA patients to the nearest hospital, which may not be a suitable center for the treatment of these patients. Future studies will show whether CACs can indeed comprehensively improve the prognosis of OHCA patients following successful prehospital resuscitation.
