Dr. Zègre-Hemsey investigates strategies to advance care for patients with acute coronary syndrome (ACS).  Specifically, her work aims to improve the early diagnosis of ACS and other cardiovascular conditions by 1) optimizing electrocardiography (ECG) for triage and risk stratification, and 2) integration of novel technologies into systems of care, both in the prehospital and acute care settings.  The overall goal of this work is to enhance timely clinical decision-making, access to definitive cardiac care, and patient outcomes.  Dr. Zègre-Hemsey is currently the principal investigator of an interdisciplinary study that seeks to better understand the use of prehospital ECG across the state of North Carolina.  Dr. Zègre-Hemsey is an emergency department nurse with a PhD in Nursing from the University of California, San Francisco (UCSF).  She is also an adult-gerontology clinical nurse specialist (CNS) with a focus on critical-care trauma.
