[Prehospital care of patients with acute ST elevation myocardial infarction].
Symptomatic prehospital therapy of patients suffering from an ST elevation myocardial infarction basically does not differ from in-hospital care regarding pain relief, beta-blockers, antiplatelets, and thrombin antagonists as well as therapy of elevated blood pressure and acute heart failure. Precondition of a targeted and adequate treatment, however, is the twelve-lead ECG whose reliability does not differ from the ECG in the hospital. Biomarkers have no role in the prehospital setting. Out-of-hospital thrombolysis, which has been proven to be superior to later in-hospital initiation, can be used as a safe strategy for reperfusion. Only the prehospital phase offers a chance to treat the majority of patients within the first 2 h after symptom onset, a time window where thrombolysis results in equal or even better outcomes with respect to mortality, if compared to percutaneous intervention. Therefore, prehospital thrombolysis should be routinely applied in areas with a weak infrastructure and few and less experienced facilities for intervention but should also be considered a principal way for earliest start of reperfusion therapy. There is increasing evidence supporting the "rescue PCI" concept in patients in whom thrombolysis has failed. By contrast, the role of "facilitated PCI" still has to be defined.
