Do you ever wonder how care delivery for the sickest patients with heart disease in the cardiac intensive care unit (CICU) has changed in the last few decades? Who belongs, both patients and providers, in the CICU? Advanced practice providers (APPs), in particular, have an increasingly important role and responsibility in supporting these complex, interdisciplinary teams.      Welcome to this episode, “Invaluable and Indispensable: Integrating Advanced Practice Providers in the Cardiac Intensive Care Unit,” the latest in our ongoing ACC CardiaCast series entitled “Conversations with Critical Care Cardiologists.” We are truly honored to welcome our esteemed guests from Duke University, Drs. Callie Tennyson and Jason Katz, to discuss their timely and topical upcoming publication in the Journal of American College of Cardiology entitled “Role of Advanced Practice Providers in the Cardiac Intensive Care Unit Team.”
