Cardiac arrest affects many individuals and is difficult to predict.

ACCESS (ACCESS to the cardiac catheterization laboratory in patients resuscitated from out-of-hospital ventricular fibrillation cardiac arrest) is a multi-center study being conducted across the US.


The standard treatment for a heart attack is to perform a cardiac catheterization to see if an artery in the heart is blocked and provide necessary treatment. Sometimes a person having a heart attack will have a normal electrocardiogram (ECG), a recording of the heart rhythm. Half of the people resuscitated from cardiac arrest that have a normal ECG are actually having a heart attack and might benefit from early cardiac catheterization. ACES People will be selected randomly (like flipping a coin) for early cardiac catheterization or intensive care unit admission.


Normally, researchers obtain permission before a person can be included in a study. After having a cardiac arrest, a person usually is unable to give consent. Since a heart attack must be treated quickly, we will spend up to 45 minutes to locate and speak with the person’s legal representative or relative about the study. If we are unable to do so, the person will be enrolled in the study without consent. This is called “Exception from Informed Consent” (EFIC). Participating sites in the DFW metroplex: Parkland Memorial Hospital and Methodist Dallas Medical Center.
