In 1984 they moved to Lowville, where they would live for 36 years together until Elaine's passing in 2020. Stuart had a celebrated career as a cardiologist and researcher. His research impacted millions globally in the field of atrial fibrillation, stroke prevention and anticoagulation.

Among his over 400 publications, Stuart published 4 of his 26 New England Journal of Medicine papers in his final year. During his forty years at McMaster, Stuart founded the cardiac arrhythmia service and served as cardiology division director.
