Background: Primary PCI is the recommended reperfusion strategy in patients with STEMI and should be initiated within 2 hours after first medical contact. In non-PCI-capable hospitals this goal is not always achievable due to delays in transfer. In these cases, thrombolysis is recommended to improve morbidity and mortality.
