Out-of-Hospital Cardiac Arrest Hypothermia Cardiac Arrest | Procedure: Early Angiography | Not Applicable |
Cardiac arrest is a major public health issue. Arizona has been a leader in improving long-term survival by introducing new and innovative resuscitation approaches including "Chest Compression-Only CPR" and "Cardiocerebral Resuscitation". Post-resuscitation care is the next great opportunity for further improvements. Early coronary angiography (CAG) combined with therapeutic hypothermia has become the recommended standard of care for post-cardiac arrest patients manifesting ST segment elevation on their electrocardiogram (ECG). However, the majority of cardiac arrest victims do not have ST segment elevation. There is clinical equipoise as to whether these patients will benefit from early CAG.
Subjects who are qualified for the study will be randomized 1:1 to one of two groups.
° Intervention Group-Early coronary angiography (door-to-angiography) within 120 minutes of admission to Emergency Department.
or
° Control Group-No early coronary angiography (within the first six hours from admission)
All enrolled patients, will be treated with therapeutic hypothermia which is standard of care, beginning simultaneously with both groups or within at least 2 hours of hospital arrival.
Subject will be followed for 180 days for safety and long-term survival.

Procedure: Early Angiography
Coronary Angiography within 120 minutes of admission for out-of-hospital cardiac arrest with ROSC |
No Intervention: Control Group
Standard of care treatment including therapeutic hypothermia in subjects post resuscitation, out-of-hospital cardiac arrest, suspicious for cardiac etiology and no ST segment elevation on ECG.

- Safety and Efficacy of early coronary angiography in the out-of-hospital cardiac arrest (OHCA) patient population. [ Time Frame: 180 days ]Safety will be assessed by evaluating any association of major adverse events (re-arrest, bleeding, pulmonary edema, hypotension, acute renal insufficiency, and pneumonia) with early coronary angiography.
- Survival from hospital at: 30 days post discharge and 180 days post discharge [ Time Frame: 30 days and 180 days ]Composite endpoint of improved left ventricular regional and global function (both regional wall motion analysis and left ventricular ejection fraction) as measured by echocardiography prior to hospital discharge, survival to discharge and favourable. Left ventricular regional function and left ventricular ejection fraction as measured by echocardiography will be measured prior to discharge or up to 180 days post hospital discharge.
- Cognitive functional status [ Time Frame: 180 days ]As measured by Modified Rankin Score (mRS) and Cerebral Performance Category (CPC) at multiple points up to 180 days post hospital discharge
- Neurocognitive Testing [ Time Frame: 180 days ]Neurocognitive function will be assessed at various time points utilizing a variety of tests from ICU discharge to 180 days post hospital discharge such as MMSE, MOCA, HADS, and IQCODE
