[Intensified prehospital treatment of heart arrest increases the number of survivors with good cerebral function].

Psychological assessment in the form of a test for dementia was carried out in 69 individuals. Thirty of these were survivors of cardiac arrest outside hospital. Seven of these were brought to hospital in ordinary emergency ambulances, 14 in heart ambulances and nine in medically staffed ambulances. In addition, 28 patients with acute myocardial infarction (AMI) and 11 control persons were examined. The result of the investigation demonstrates that the more intensive the prehospital treatment of cardiac arrest, the more patients survive with good cerebral function. In particular, the percentage of cerebral damage was least in cases where a medically staffed ambulance was employed.
