Cardiac Catheterization in Cardiac Arrest

Role of Early Cardiac Catheterization in Cardiac Arrest

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.

Study Overview

• Status: Unknown
• Conditions: Out of Hospital Cardiac Arrest
• Intervention / Treatment: Procedure: Cardiac catheterization

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

Number of Arms

2

Arms and Interventions

Participant Group / 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 Names: 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.
