Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Other groups have studied the neurological predictive values of biomarkers after OHCA. A variety of proteins including S100B, neuron-specific enolase, and G-FAP, co-peptin, Tau, neurofilament light/ heavy chain, and secretoneurin have been proposed as potential biomarkers of neurological outcome at OHCA. Unfortunately, many of these have been shown to have several drawbacks. For example, some lack specificity due to being released during resuscitation (e.g., S100B is found extracerebrally in muscle, adipocytes, and chondrocytes, creating a confounding factor in CA patients receiving chest compressions). Others have lacked sufficient sensitivity in the prognosticating of neurological outcome (ref). Furthermore, there is a paucity of human studies in cardiac arrest on newer biomarkers that have been studied in other acute brain injury disease processes that could potentially serve as candidate biomarkers predicting neurological outcome at post cardiac arrest hypoxic brain injuries. Biomarkers such as UCH-L1, SBDP, and MBP have not been studied in a OHCA cohort.
The Investigator therefore propose a prospective, observational study in which the investigator will incorporate a minimally invasive and minimal risk measurement of blood biomarkers at time of ROSC. This would be done by drawing blood at ROSC (0-59mins), and additional blood draws at hours 6, 12, 18, 24, 48, 72, and on day 4, 5, and 6. The Investigator will then determine whether biomarker levels correlates with survival to hospital admission, survival to hospital discharge, and functional neurologic outcome at discharge and at 6 months. The Investigator intend to sample patients that present to the emergency department with non-CA chest pain in our study as well, which will allow us to draw stable inferences.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Cardiac Arrest cohort
adult patients (≥ 18 years of age) with non-traumatic out of hospital cardiac arrest
blood draw
Blood draws will be collected via venipuncture or IV at hours 0, 6, 12, 18, 24, 48, 72, 96, 120, 144 (10 draws total). Each draw would be approximately 20 mL of blood (but no less than 10 mL).
Control cohort
matched control population will include hemodynamically stable patients who present to the ED with chest pain that is not of cardiac etiology (non-traumatic chief complaints).
blood draw
Blood draws will be collected via venipuncture or IV at hours 0, 6, 12, 18, 24, 48, 72, 96, 120, 144 (10 draws total). Each draw would be approximately 20 mL of blood (but no less than 10 mL).
