Legendary cardiologist’s groundbreaking work reshaped global understanding of heart disease over seven decades
Dr. Eugene Braunwald, widely regarded as the “father of modern cardiology,” passed away on April 22, 2026, at the age of 96. A towering figure in cardiovascular medicine, his pioneering research and leadership transformed the diagnosis and treatment of heart disease worldwide.
A Life Shaped by Adversity and Excellence
Born in Vienna, Austria, in 1929, Eugene Braunwald fled the Nazi occupation as a child and immigrated to the United States as a refugee—an experience he often credited for shaping his resilience and work ethic. He went on to earn both his undergraduate and medical degrees from New York University and completed his residency at Johns Hopkins Hospital.
Transforming Cardiology and Medical Science
Over a career spanning more than 70 years, Braunwald made landmark contributions to understanding cardiovascular diseases, particularly hypertrophic cardiomyopathy (HCM). His 1964 monograph with collaborator Andrew Morrow was the first to define HCM as a distinct clinical condition, a breakthrough that continues to guide cardiology today.
He later founded the TIMI Study Group in 1984, revolutionising large-scale clinical trials in cardiovascular medicine and significantly improving treatment strategies for heart attack patients.
Leadership Across Prestigious Institutions
Throughout his illustrious career, Braunwald held several influential positions. He served as Chief of Cardiology and Clinical Director at the National Heart, Lung and Blood Institute, founding Chair of Medicine at the University of California San Diego, and later chaired the Department of Medicine at Brigham and Women’s Hospital. He was also a Distinguished Professor at Harvard Medical School.
A Lasting Impact on Medical Education
Braunwald’s influence extended far beyond clinical practice. He was the founding editor of Braunwald’s Heart Disease, one of the most authoritative textbooks in cardiology, and a long-time editor of Harrison’s Principles of Internal Medicine. With over 1,000 peer-reviewed publications, he became one of the most cited cardiologists in history.
Tributes Pour In from Global Medical Community
Prominent figures in cardiology paid tribute to his legacy. Valentin Fuster praised his ability to foresee the future of medicine, while Marc Sabatine highlighted his mentorship and transformative vision through the TIMI Study Group.
Roxana Mehran, President of the American College of Cardiology, described him as “a legend of all legends,” whose contributions spanned decades and touched countless lives.
A Vision for the Future of Cardiology
Even in his later years, Braunwald remained deeply engaged in advancing the field. In a 2022 interview, he expressed optimism about the future, predicting that heart disease may no longer remain the leading cause of death in the United States within the next 50 years.
