Sophia Antipolis, France - 24 April 2026: The European Society of Cardiology (ESC) is deeply saddened by the passing of Professor Eugene Braunwald, MD, one of the most influential figures in the history of cardiovascular medicine, who died on 22 April 2026, aged 96.
Born in Vienna, Austria, Professor Braunwald fled Nazi persecution as a child, eventually settling in the United States, where he trained in internal medicine and cardiology and began a career defined by curiosity, courage, and an unwavering commitment to patients. From early work at the National Institutes of Health to transformative academic leadership at Harvard Medical School and Brigham and Women’s Hospital, he helped build institutions, teams, and ideas that shaped cardiovascular medicine for generations.
Beyond his scientific brilliance, Professor Braunwald was celebrated for his humanity: a generous teacher who made time for young clinicians and investigators; a rigorous but kind-minded mentor who set high standards while giving others confidence; and a colleague whose curiosity, humility and warmth shaped the culture of the teams he led. Across decades, countless cardiologists around the world considered him not only an academic leader but a guiding voice in the clinic and in life.
“Professor Braunwald was the pioneering cardiologist of his time. His vision and innovation changed the trajectory of cardiovascular medicine,” said Professor Thomas F. Lüscher, President of the European Society of Cardiology. “He had a rare ability to see what the field needed next, and then to build the science and the evidence that made better care possible; from the way we understand myocardial ischaemia to the way we test and deliver life-saving therapies. Just as importantly, he set a standard for intellectual honesty and mentorship, giving generations of clinicians and researchers the confidence to aim higher.”
Professor Braunwald’s work helped define how cardiovascular disease is understood and treated. Early in his career, he established foundational concepts of human cardiovascular physiology and pathophysiology, including the determinants of myocardial oxygen consumption. He also helped pioneer transseptal left heart catheterisation (with John Ross), advancing the assessment of valvular heart disease at a time when open-heart surgery was just beginning. These insights informed his landmark work on hypertrophic cardiomyopathy, including the recognition of dynamic left ventricular outflow tract obstruction and an early appreciation of its frequent genetic basis. In heart failure, he described an early neurohumoral abnormality (increased sympathomimetic activation with elevated circulating catecholamines) and contributed to the clinical assessment of ventricular performance, including the use of the ejection fraction and ventricular systolic dp/dt. He later helped transform acute coronary care by championing the concept that myocardial infarction is a dynamic process in which early, decisive intervention can salvage threatened myocardium.
In 1984, he founded the Thrombolysis in Myocardial Infarction (TIMI) Study Group, setting a benchmark for large-scale cardiovascular clinical trials and accelerating the translation of evidence into practice. Through TIMI and related programmes, his leadership influenced generations of studies that reshaped the care of patients with acute coronary syndromes, including reperfusion strategies and preventive therapies.
Professor Braunwald’s impact also reached far beyond any single laboratory or trial. As founding editor of Braunwald’s Heart Disease and a long-time editor of Harrison’s Principles of Internal Medicine, he helped educate generations of physicians and shaped the global language of cardiovascular medicine.
The ESC recognised Professor Braunwald’s exceptional contributions with its highest honour, the ESC Gold Medal, awarded to him in 2004. The award reflected not only a lifetime of landmark discoveries but also his enduring commitment to raising standards in research, education, and patient care worldwide. The Heart Failure Association of the ESC also honours Professor Braunwald each year at its annual congress with the HFA Eugene Braunwald Lecture. Professor Braunwald continued to make regular contributions to the European Heart Journal’s ‘Braunwald Corner’, last publishing in January this year. He remained active throughout his career, most recently giving an interview on ESC TV Today in 2023.
“Eugene Braunwald exemplified what academic medicine can be at its very best: precise thinking, fearless innovation, and an unwavering focus on what improves patients’ lives,” said Professor Filippo Crea, Editor-in-Chief of the European Heart Journal. “He had a rare ability to connect fundamental biology to clinical decisions, and to do so while elevating everyone around him.”
Professor Cecilia Linde, ESC President-elect, added: “For early-career cardiologists, Professor Braunwald has been a living legend. He was proof that curiosity, discipline and kindness can coexist at the highest level. We will honour his legacy by investing in the next generation and by pursuing research that is both bold and clinically meaningful.”
The ESC extends its deepest condolences to Professor Braunwald’s family and loved ones, and to his many students, collaborators, and friends across the world. His legacy endures in the patients whose lives have been saved by evidence-based cardiovascular care, and in the people he inspired to pursue medicine with integrity and purpose.
