There is a continuing controversy about the acceptable time-window for primary percutaneous coronary intervention (PPCI) in patients with ST-elevation myocardial infarction (STEMI). Recent American and European guidelines recommend PPCI if the delay in performing PPCI instead of administering fibrinolysis (PCI-related delay) is <60 min and the presentation delay is more than 3 h. ⋯ Furthermore, the previous assumption that PPCI is less time-dependent than fibrinolysis is questioned. To maximise the number of patients with STEMI eligible for PPCI the optimal logistic may be to establish the diagnosis in the prehospital phase, to bypass local hospitals and re-route patients directly to catheterisation laboratories running 24/7.

Review Meta Analysis
Routine use of oxygen in the treatment of myocardial infarction: systematic review.
International guidelines recommend the routine use of oxygen therapy in the treatment of myocardial infarction (MI). ⋯ The limited evidence that does exist suggests that the routine use of high-flow oxygen in uncomplicated MI may result in a greater infarct size and possibly increase the risk of mortality.
