DALLAS, July 6, 2026 — The American Heart Association announced that effective with today’s issue, Bradley A. Maron, M.D., FAHA, is the new editor-in-chief of Circulation , the Association’s flagship peer-reviewed journal and one of the world’s leading scientific publications in cardiovascular medicine. In the role, Maron will help shape the journal’s editorial direction and continue its commitment to publishing rigorous, practice-changing science for clinicians, researchers and healthcare professionals worldwide.
Maron is a board-certified clinical cardiologist and distinguished researcher across the basic, translational, clinical and population health spectrum. He is recognized globally for mechanistic and clinical advances in pulmonary hypertension, right heart failure and cardiomyopathy, and his career bridges patient care, translational science and precision medicine, focused on pulmonary vascular disease, specifically how conditions that affect the blood vessels within the lungs impact the heart. Maron is senior associate dean for precision medicine, director of the Pulmonary Hypertension Center at the University of Maryland Medical Center, and the Melvin Sharovsky Professor of Medicine at the University of Maryland School of Medicine in Baltimore, as well as co-executive director of the University of Maryland Institute for Health Computing in Bethesda, Maryland. He previously held faculty appointments at Harvard Medical School and also served as a visiting professor of medicine at Imperial College London.
Maron succeeds Joseph A. Hill, M.D., FAHA, who has led Circulation since 2016, and Joseph Loscalzo, M.D., Ph.D., FAHA, who was Circulation’s editor-in-chief from 2004-2016.
“Dr. Maron’s appointment as the next editor in chief of Circulation underscores the American Heart Association’s commitment to advancing transformative science shaping the future of cardiovascular medicine,” said Shelley Miyamoto, M.D., FAHA, chair of the Association’s Scientific Publishing Committee, which selected Dr. Maron to lead the editorial content of Circulation . Each of the Association’s scientific journals is editorially independent of one another, and they are also editorially independent of the Association in support of open dialogue and discourse, which are essential to the dynamic nature of scientific discovery and advances. “His vision, scientific breadth and dedication to robust research and innovation position Circulation for optimal success in its next chapter of influence and impact.”
“I am deeply honored to take on the remarkable role of leading Circulation ,” said Maron. “I have pored over issues of Circulation since my early research career and marveled at the strength of the science and the rigorous standards. I am energized to forge a new path for the journal that strengthens and expands on the legacy and success of the editors before me, particularly Drs. Hill and Loscalzo, to whom I am grateful. Our mission is to reinvigorate the type of cardiovascular science and medicine published in Circulation , and fast track that information to our readers with additional transparency. A key goal is to share findings and perspectives from articles in Circulation in more engaging ways than ever before.”
Top new features of Circulation will include:
Several additional upgrades for readers will roll-out in the first year.
Dr. Maron is joined by a new Circulation editorial team including:
In addition, 10 renowned specialists are now deputy editors for specific topic sections within the journal:
Circulation will also be supported by a team of 27 associate editors and guest editors.
Maron earned a bachelor’s degree in psychology from Williams College and a doctor of medicine degree from Brown University School of Medicine, after beginning his medical studies at Tulane University School of Medicine. He completed his internal medicine training at Boston Medical Center and Boston University School of Medicine, followed by residency and a cardiovascular medicine fellowship at Brigham and Women’s Hospital and Harvard Medical School, with mentors Joseph Loscalzo, M.D., Ph.D., FAHA, and Jane A. Leopold, M.D., FAHA.
Maron’s scientific impact includes co-authoring more than 260 scientific publications including peer-reviewed manuscripts, book chapters and other publications. He has served as the primary investigator for federally funded and collaborative research programs for more than two decades, discovered novel molecular mechanisms of vascular fibrosis, led projects that clarified clinical risk and resilience in pulmonary hypertension, co-led a project using AI to automate clinical diagnosis, and helped advance the use of network medicine, big data and computational science to improve disease phenotyping and therapeutic discovery. Maron is a global leader in the basic mechanisms of pulmonary vascular remodeling and precision medicine, with six patents, inventions and copyrights confirmed or pending.
He also brings substantial editorial and professional leadership experience, including prior reviewer and editor roles with multiple cardiovascular and respiratory journals, such as Circulation, The Lancet, The New England Journal of Medicine, PLOS Medicine, Science Translational Medicine, the Journal of Clinical Investigation, Annals of Internal Medicine, JAMA: Cardiology, the American Journal of Respiratory and Critical Care Medicine (Blue Journal), and JACC. Maron has also served in several volunteer leadership roles for the American Heart Association, the American College of Cardiology and the Pulmonary Vascular Research Institute.
Circulation is the flagship peer-reviewed journal of the American Heart portfolio of 14 peer-reviewed scientific journals: Stroke; Hypertension ; Journal of the American Heart Association ; Arteriosclerosis, Thrombosis, and Vascular Biology ; Circulation Research ; Circulation: Arrhythmia and Electrophysiology ; Circulation: Heart Failure ; Circulation: Cardiovascular Imaging ; Circulation: Cardiovascular Interventions ; Circulation: Genomic and Precision Medicine; Circulation: Population Health and Outcomes; Stroke: Vascular and Interventional Neurology; and Annals of Internal Medicine: Clinical Cases . Each journal is editorially independent of one another, and they are also editorially independent of the Association in support of open dialogue and discourse, which are essential to the dynamic nature of scientific discovery and advances. Editors-in-chief are selected by the Association’s volunteer-led Scientific Publishing Committee, and each editor-in-chief assembles and manages the editorial board, vision and strategy for their journal. The Association is the publisher of the journals; however, the Association has no oversight on the scientific content published. Studies published in the American Heart Association’s scientific journals are peer-reviewed. The statements and conclusions in each manuscript are solely those of the study authors and do not necessarily reflect the Association’s policy or position. The Association makes no representation or guarantee as to their accuracy or reliability.
The Association receives more than 85% of its revenue from sources other than corporations. These sources include contributions from individuals, foundations and estates, as well as investment earnings and revenue from the sale of our educational materials. Corporations (including pharmaceutical, device manufacturers and other companies) also make donations to the Association. The Association has strict policies to prevent any donations from influencing its science content and policy positions. Overall financial information is available here .
