Pre-treatment with clopidogrel results in a reduction of ischaemic events in non-ST-elevation acute coronary
syndromes. Data on upstream clopidogrel in the setting of primary percutaneous coronary intervention (PCI) are
limited. The aim of this study was to investigate whether clopidogrel loading before arrival at the PCI centre may
result in an improved outcome of primary PCI for ST-elevation myocardial infarction (STEMI)
