Marina Del Rios, MD, MS, FAHA is an emergency medicine physician and a health services researcher. Much of her scholarship seeks to bridge clinical resuscitation science with public health and equity, examining not just who survives a cardiac arrest, but where they live, what system-level factors contribute to inequities, and how to build more just systems of care. Her work also touches broadly on health disparities, extending beyond cardiac arrest to chronic disease management (e.g., hypertension in the ED), science communication, pandemic preparedness, and post-arrest resource allocation. Her research has received competitive funding from the National Institutes of Health, the American Heart Association, Medtronic Philanthropy, the Pritzker Traubert Family Foundation, and the Robert Wood Johnson Foundation. Her approach is deeply community-oriented: she does not just study disparities, she actively works to reduce them through partnerships with community organizations and advocacy.
Dr. Del Rios has also played a prominent role in guideline development and policy translation. She was a co-author of the 2015 report “Strategies to Improve Cardiac Arrest Survival: A Time to Act”, published by the National Academy of Science, Engineering, and Medicine. She has also contributed to multiple scientific statements and evidence updates published by the American Heart Association (AHA). She is the immediate past Chair of the Science Subcommittee of the Emergency Cardiovascular Care Committee of the AHA and provided oversight to evidence evaluation and development of the 2025 AHA Guidelines for CPR and ECC. Her involvement in these works highlights the importance of community-level and policy change, not just clinical interventions, to ensure that issues of equity and quality are embedded in national standards of cardiac arrest systems of care.
