  Purpose

The use of supplemental oxygen in the setting of suspected acute myocardial infarction (AMI) is manifested in international treatment guidelines and established in prehospital and hospital clinical routine throughout the world.

However, to date there is no conclusive evidence from adequately designed and powered trials supporting this practice. Existing data is conflicting and failing to clarify the role of supplemental oxygen in AMI.

The DETO₂X-AMI trial is designed to shed light on this important issue.

Primary Outcome Measures:
  • 1-year all-cause mortality [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    1-year all-cause mortality on an intention to treat basis (ITT)


Secondary Outcome Measures:
  • Myocardial damage [ Time Frame: Participants will be followed for the duration of hospital stay, an expected average of 3-5 days ] [ Designated as safety issue: No ]
    Myocardial damage assessed by cardiac resonance imaging (CMR), by electrocardiogram, biomarkers and coronary angiography using the index of microvascular resistance (IMR)

  • Mortality and morbidity [ Time Frame: Participants will be followed for the duration of hospital stay, an expected average of 3-5 days, at 30 days and 1-year ] [ Designated as safety issue: No ]
    Evaluate mortality during hospital stay, at 30 days and 1-year.

  • Heart failure evaluation [ Time Frame: Participants will be followed for the duration of hospital stay, an expected average of 3-5 days ] [ Designated as safety issue: No ]
    Assessment of the degree of heart failure by echocardiography, biomarkers and number of patients needing medical (iv-drugs such as furosemide, nitroglycerine or inotropes) and/or mechanical (CPAP) assistance.

  • Health economics [ Time Frame: Health economics will be assessed from first contact with the ambulance service through to the duration of hospital stay, an expected average of 3-5 days ] [ Designated as safety issue: No ]
    Health economics concerning supplemental oxygen treatment from prehospital contact of the emergency service through to hospital discharge


Estimated Enrollment: 6600
Study Start Date: April 2013
Estimated Study Completion Date: December 2015
Estimated Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: No oxygen

For patients randomised to withholding oxygen treatment

  • no oxygen is administered at any time as long as the oxygen saturation is ≥90% on pulse oximeter (repetitive checks are performed)
  • all patients receive standard acute coronary syndrome treatment including reperfusion strategies
  • observation duration 12 hours
Active Comparator: Oxygen

For patients randomised to oxygen therapy:

  • 6 L/min of oxygen delivered by oxymask® started immediately after inclusion of the ambulance service or in the emergency department given continuously for 6-12 hours (at least 6 hours)
  • all patients receive standard acute coronary syndrome treatment including reperfusion strategies
Drug: Oxygen
