Just Breathe: Supplemental Oxygen Provides No Benefit in Acute Myocardial Infarction

From Urgent Matters:

The DETO2X-AMI study showed that administering supplemental oxygen to non-hypoxic patients with suspected AMIs did not improve mortality at either one month or one year.  Additionally, administration of oxygen did not appear to affect infarct size as both groups had similar troponin levels.  To date, the DETO2X-AMI trial is the largest randomized controlled clinical that evaluates the use of supplemental oxygen in AMI.  Its findings cast doubt on the benefit of routine oxygen therapy in these patients.  With this evidence, clinicians should consider supplemental oxygen ineffective in AMI patients without hypoxia, and ultimately it may be removed from clinical guidelines.
