Paterson, Ian

Ian Paterson, MD, is a cardiologist at the University of Ottawa Heart Institute and a professor in the Faculty of Medicine at the University of Ottawa. 


Dr. Paterson received his medical degree from McGill University in 1995. He completed post-graduate medical training in internal medicine, cardiology, and echocardiography in 2002. He subsequently completed a fellowship in cardiac magnetic resonance imaging (MRI) at the National Institutes of Health. The University of Alberta recruited him to its division of cardiology in 2004. Dr. Paterson served as director of residency training in adult cardiology from 2009-2017. He continued as an associate program director thereafter. Dr. Paterson was co-founder and clinical director of the Edmonton Cardio-Oncology Program and academic/research director for cardiac MRI at the Mazankowski Alberta Heart Institute.

Dr. Paterson is a board member of the Canadian Cardiac Oncology Network and the Canadian Society of Cardiovascular Magnetic Resonance. He has chaired and/or co-authored position statements and guidelines, and has led CIHR-funded, multi-centre clinical trials in cardio-oncology and cardiac MRI.

Dr. Paterson joined the UOHI in 2022 as co-lead of the Cardiac MRI Program and director of the Canadian Centre for Rare Cardiac Conditions.

Research and clinical interests

Dr. Paterson’s research interests include cardiovascular imaging in heart failure, cardiomyopathy, cardio-oncology, and post-COVID syndrome. He has published hundreds of scientific articles, abstracts, and book chapters, and frequently presents his research regionally, nationally, and internationally.
