Brief Summary:
This is a pilot study that will lead to a large randomized control trial (RCT), to assess whether early versus late or no cardiac catheterization is associated with improved outcomes in out-of-hospital cardiac arrest (OHCA) patients.

Condition or disease Intervention/treatment Phase
Out of Hospital Cardiac Arrest Procedure: Cardiac catheterization Not Applicable

Detailed Description:

A pilot multicenter RCT.

The objectives of the study are:

To assess whether early (within 12 hours) cardiac catheterization is associated with improved survival, neurologic and cardiovascular outcomes in OHCA patients.

Patients will be randomized 1:1 to early cardiac catheterization, performed as early as possible, within 12h post return of spontaneous circulation (ROSC) following OHCA, or to standard practice, which may include medical management without cardiac catheterization or late cardiac catheterization after completion of therapeutic hypothermia. Percutaneous coronary intervention (PCI) is recommended for culprit lesions found on diagnostic angiography. All patients will undergo therapeutic hypothermia started as soon as possible with target temperature below 36°C according to local practice. Other medical management will be according to standard of care

Arm Intervention/treatment
Active Comparator: Early cardiac catheterization
Cardiac catheterization performed as early as possible, within 12h post ROSC following OHCA, with possible PCI during mild therapeutic hypothermia or apyrexia
Procedure: Cardiac catheterization
Cardiac catheterization / coronary angiography is a diagnostic procedure used to define the coronary anatomy and presence of obstructive coronary lesions or culprit lesions. According to the findings, it may lead to percutaneous coronary intervention (PCI) using stents
Other Name: Coronary angiography

No Intervention: Medical arm
Initial therapy does not include cardiac catheterization. Cardiac catheterization with possible PCI is allowed after completion of mild therapeutic hypothermia or apyrexia for >24h post ROSC.

Primary Outcome Measures :
  1. Composite of death and poor neurologic outcomes ( Cerebral Performance Category [CPC] score 3-5). [ Time Frame: 30 days ]

Secondary Outcome Measures :
  1. Death [ Time Frame: 30 day ]
  2. CPC score [ Time Frame: up to 30 days ]
  3. Acute kidney injury- creatinine levels [ Time Frame: 48 hours ]
    Number of participants with increase in serum creatinine of ≥44.2 μmol/L, or a 25% relative rise in creatinine, within 48 h after contrast exposure42

  4. Myocardial infarction - according to cardiac troponin levels [ Time Frame: 30 days ]
    Number of participants with myocardial infarction post percutaneous coronary interventions, in accordance with the universal definition of myocardial infarction.

  5. Stent thrombosis by pathology or angiography [ Time Frame: 30 days ]
    Number of participants with definite stent thrombosis confirmed by angiography or pathology according to the Academic research consortium criteria

  6. Bleeding - according to Hb levels [ Time Frame: 30 days ]
    Number of participant with overt bleeding according to Academic Research Consortium criteria

  7. Composite of death and poor neurologic outcome [ Time Frame: 1 year ]
  8. Stroke - imaging or pathology [ Time Frame: 30 days ]
    New stroke following hypothermia confirmed by imaging (computer tomography or magnetic resonance imaging)

  9. Heart failure (NYHA 3-4) [ Time Frame: 30 days ]
  10. Estimated cost per patient according to length of stay and procedures performed [ Time Frame: 30 days ]
