CARSK stands for the "Canadian-Australasian Randomised Trial of Screening Kidney Transplant Candidates for Coronary Artery Disease."
CARSK is an investigator-initiated, multicentre, non-inferiority, two-parallel-arm randomized trial. It aims to test the hypothesis that after screening for waitlist entry, no further screening for coronary artery disease (CAD) is not inferior to the current standard care, which is screening all asymptomatic waitlisted patients for CAD at regular intervals.
Additionally, it will compare the benefits and costs of not screening versus regular CAD screening from a health system perspective.
Why is this trial important?
Cardiovascular disease is the commonest cause of death while on the kidney transplant waitlist and after transplantation. Current standard care involves screening for coronary artery disease prior to waitlist entry, then every 1-2 years, according to perceived risk, until transplanted. This current screening strategy is not evidence based, has substantial known and potential harms, and is very costly.
