DALLAS - July 6, 2026 (NEWMEDIAWIRE) - 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:

• A new Clinician Lighthouse article: Expert-guided interpretation of diagnostic test results and patient management for practicing clinicians.
• A new Clinician’s Corner: Clinician-oriented content that guides readers through key decision-making and real world clinical practice.
• Key clinical trials and guideline manuscripts supported by perspective bundles that provide valuable context, details and insight.
• Graphic abstracts for all research articles, central illustrations for most invited papers, and video commentaries for select manuscripts.
• A streamlined and strengthened manuscript submission process with an accelerated and more transparent review timeline.
• A new Patient’s Corner article: For the public/patient community, these articles are commissioned by the editors to thematically tie to and present key content. These articles may focus on a clinical trial manuscript, scientific statement, guideline or invited review article, for example.
• Expanded, weekly eTOC (electronic Table of Contents) alerts including brief summaries of articles.  

Several additional upgrades for readers will roll-out in the first year.

Dr. Maron is joined by a new Circulation editorial team including:

• Executive Editor Karen E. Joynt Maddox, M.D., M.P.H., FAHA, a professor of medicine and public health and the co-director of the Center for Advancing Health Services, Policy & Economics Research at Washington University School of Medicine in St. Louis, Missouri, and
• Deputy Executive Editor Sadiya S. Khan, M.D., M.Sc., FAHA, the Magerstadt Professor of Cardiovascular Epidemiology, an associate professor of cardiology and preventive medicine, and director of the Center for Population Science & Aging at Northwestern University’s Feinberg School of Medicine in Chicago. 

In addition, 10 renowned specialists are now deputy editors for specific topic sections within the journal:

• Fundamental Sciences - Joseph C. Wu, M.D., Ph.D., FAHA, from Stanford University in Stanford, California, and a past president of the Association (2023-2024);
