Bradley A. Maron, M.D., Appointed Editor-in-Chief of Circulation, Promises Innovation and Transparency

The American Heart Association announced that Bradley A. Maron, M.D., FAHA, has been appointed as the new editor-in-chief of Circulation, its flagship peer-reviewed journal, effective with the July 6, 2026 issue. Maron, a board-certified clinical cardiologist and distinguished researcher in pulmonary hypertension and right heart failure, succeeds Joseph A. Hill, M.D., FAHA, who led the journal since 2016, and Joseph Loscalzo, M.D., Ph.D., FAHA, who served from 2004 to 2016. This leadership change signals a continued commitment to publishing transformative cardiovascular science while introducing new features to make research more accessible to clinicians and patients.

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. He also co-executive directs the University of Maryland Institute for Health Computing. His career bridges patient care, translational science, and precision medicine, with a focus on pulmonary vascular disease. With over 260 scientific publications, six patents, and extensive editorial experience, Maron brings a vision to reinvigorate the type of cardiovascular science published in Circulation and fast-track information to readers with additional transparency.

Shelley Miyamoto, M.D., FAHA, chair of the Association’s Scientific Publishing Committee, which selected Maron, stated: “Dr. Maron’s appointment underscores the American Heart Association’s commitment to advancing transformative science shaping the future of cardiovascular medicine. His vision, scientific breadth and dedication to robust research and innovation position Circulation for optimal success in its next chapter of influence and impact.” The journal maintains editorial independence from the Association to support open dialogue essential for scientific discovery.

Under Maron’s leadership, Circulation will introduce several new features. A new Clinician Lighthouse article will offer expert-guided interpretation of diagnostic test results and patient management for practicing clinicians. A Clinician’s Corner will provide clinician-oriented content guiding key decision-making and real-world practice. Key clinical trials and guideline manuscripts will be supported by perspective bundles offering context and insight. Graphic abstracts will accompany all research articles, central illustrations for most invited papers, and video commentaries for select manuscripts. The submission process will be streamlined with an accelerated and more transparent review timeline. A new Patient’s Corner will present commissioned articles for the public and patient community, thematically tied to key content such as clinical trial manuscripts or scientific statements. Expanded weekly eTOC alerts will include brief summaries of articles. Additional upgrades will roll out within the first year.

Maron is joined by a new editorial team including Executive Editor Karen E. Joynt Maddox, M.D., M.P.H., FAHA, from Washington University School of Medicine, and Deputy Executive Editor Sadiya S. Khan, M.D., M.Sc., FAHA, from Northwestern University. Ten deputy editors oversee specific sections: Fundamental Sciences by Joseph C. Wu, M.D., Ph.D., FAHA; Translational Science, Therapeutics and Physiology by Matthew L. Steinhauser, M.D.; Clinical Cardiology by Jennifer E. Ho, M.D., FAHA, and Ryan J. Tedford, M.D., FAHA; Clinical Trials by Adrian F. Hernandez, M.D., M.H.S., FAHA, and P. Gabriel Steg, M.D.; Community Health by Tiffany Powell-Wiley, M.D., M.P.H., FAHA; Population Health by Mercedes Carnethon, Ph.D., FAHA; Global Cardiovascular Health by Ana Mocumbi, M.D., Ph.D.; and AI for Process and Science by Thomas M. Maddox, M.D., M.Sc., FAHA. The journal will also be supported by 27 associate editors and guest editors.

This appointment is significant for Texas and the broader medical community as it highlights the ongoing evolution of cardiovascular research dissemination. For clinicians and researchers in Texas, the new features promise more actionable insights and faster access to practice-changing science. The emphasis on transparency and patient engagement aligns with trends in precision medicine and value-based care, potentially influencing how cardiovascular care is delivered in the state. As Circulation continues to be a leading source of cardiovascular knowledge, these changes could accelerate the translation of research into clinical practice, benefiting patients and healthcare systems alike.
