Why the study?
Does off-hours hospital presentation increase early mortality and major cardiovascular outcomes in patients with STEMI undergoing primary PCI compared to on-hours presentation?
Does off-hours hospital presentation increase early mortality and major cardiovascular outcomes in patients with STEMI undergoing primary PCI compared to on-hours presentation?
Off-hours STEMI presentation may worsen early outcomes after primary PCI; leaves open whether system changes improve survival.
Early reperfusion therapy is crucial in patients with ST-elevation myocardial infarction (STEMI). Off-hours hospital presentation may increase the time from pain to coronary reperfusion, and it may be responsible for increased cardiovascular outcomes. The aim of this study was to compare the effect of different times of presentation (on-and off-hours) on early mortality and major cardiovascular outcomes in patients with STEMI who underwent primary percutaneous coronary intervention (PCI).
