Overview
The goal of this randomized controlled trial is to assess the impact of disclosing a high polygenic risk result for coronary artery disease on change in cardiovascular health over one year.
Description
The main question PROACT 1 aims to answer is whether cardiovascular health improves following disclosure of high polygenic risk result for coronary artery disease compared to standard of care.
This is a 1:1 randomized controlled trial of middle-aged participants with no known cardiovascular disease, are not on lipid-lowering therapy, who have high polygenic risk score for coronary artery disease, and do not have quantifiable plaque on coronary computed tomography angiography. Participants will be randomized into two equal groups: one group will receive their high polygenic risk result for coronary artery disease at baseline, and the other group will receive their result after study completion at 1 year. Change in cardiovascular health as measured by the American Heart Association Life's Essential 8 score from baseline to one-year will be compared.
