Post-Cardiac Arrest Service (PCAS)

Post Cardiac Arrest Service (PCAS)

We study the resuscitation and management of patients who survive cardiopulmonary resuscitation (CPR). A variety of physiological changes occur after cardiac arrest. Individual patients can experience none, some or all of these changes. Mortality is most often related to brain injury or multiple organ failure.

Pitt EM Researchers Helping Cardiac Arrest Survivors

Over 300,000 Americans have their hearts stop yearly. Nationally, less than 10% survive and of those who do, there seems to be a large burden of depression and anxiety. Researchers at the University of Pittsburgh Center for Cardiac Arrest Survival (CCAS) are hoping to assess this mental health burden and are reaching out to the community to help.

As part of a Pitt research project, CCAS faculty member, Dr. Ankur Doshi , is providing home-based CPR training kits to cardiac arrest survivors hoping to affect the rates of depression and anxiety. The Center is spearheading a crowdfunding campaign through the University of Pittsburgh to raise money for these kits.

With the decline of government funding of scientific research, projects like this are increasingly reliant on people like you. The CCAS researchers want you to join life-saving work by donating to this campaign. Please go to the Cardiac Arrest Survivors Support website at https://engage.pitt.edu/cardiacarrest to donate and/or learn more!

Current Studies

PCAS recruits subjects for observational studies and trials during their clinical care.

COMICA (Characterization of Mitochondrial Injury after Cardiac Arrest) is a study sponsored by NIH through the CTSA network. This study partners our department with three other university programs - Virginia Commonwealth University, University of Pennsylvania and Beth Israel - Deaconess (Harvard University). Subjects provide blood samples and detailed clinical information for a multicenter database and tissue repository. Initial studies will examine biological markers of mitochondrial stress that are expected to occur after ischemia-reperfusion associated with cardiac arrest.

Safety and Pharamacokinetics of Levetiracetam in Post-Arrest Patients is a single-arm trial of the intravenous anticonvulsant levetiracetam to suppress seizures which are common during the first few days after cardiac arrest.

Functional Outcomes II is a trial of the effectiveness of the "Maximizing Energy (MAX)" intervention for reducing the severity of fatigue and improving performance and participation in daily activities in patients during the months after cardiac arrest.
