Long-term Risk of Cardiovascular Disease in Living Kidney Donors

The investigative team will conduct a population-based, matched retrospective cohort study across Ontario, Alberta, and British Columbia using linked administrative healthcare databases to evaluate the long-term risk of major adverse cardiovascular events (MACE) among living kidney donors compared with matched healthy nondonors. Living kidney donors who donated between 1992 and 2024 will be included and matched 1:10 to a carefully selected population of nondonors based on key demographic and clinical characteristics. The primary outcome is a composite of cardiovascular death, hospital admission for myocardial infarction, or hospital admission for ischaemic stroke. Secondary outcomes will examine each component of the composite separately and all-cause mortality. The results will provide evidence to inform clinical guidelines, support informed decision-making for potential donors and recipients, and guide counselling by transplant clinicians.
