Giving adults their genetic risk score for coronary artery disease to see if it changes heart health.
Official title: PROACT 3: Impact of Disclosing Coronary Artery Disease Polygenic Risk Score on Cardiovascular Health
Run by Massachusetts General Hospital · NCT07087431 · Data updated 2026-11-12
This will see if telling adults aged 30–75 their genetic risk score for coronary artery disease changes LDL cholesterol and preventive care actions over one year.

Is this trial a fit for you?
✓Likely a good fit
Adults 30–75 with established primary care at Mass General Brigham who do not have cardiovascular disease and are not currently taking LDL-lowering medications.
✕Probably not a fit
People already on statins or other LDL-lowering drugs, those with existing cardiovascular disease, or those without Mass General Brigham primary care would not qualify and are unlikely to benefit from this study's approach.

What this trial studies
The PROACT 3 trial randomizes 500 adults aged 30–75 who receive primary care within the Mass General Brigham network and are not taking LDL-lowering medications. All participants undergo a polygenic risk score test for coronary artery disease and are assigned 1:1 to immediate disclosure of results or deferred disclosure after about 12 months. The primary outcome is change in LDL cholesterol from baseline to 12 months, and secondary outcomes include change in the American Heart Association Life's Essential 8 score plus measures of engagement with preventive care (lipid panels, blood pressure checks, primary care visits, and initiation of preventive therapies). The single-center trial uses electronic health record queries to identify eligible patients and is conducted at Massachusetts General Hospital.
Why it matters
Potential benefit: If successful, disclosing genetic risk could prompt earlier lifestyle or medication changes that lower LDL cholesterol and reduce long-term heart disease risk.
How similar studies have gone: Prior studies of disclosing polygenic risk scores for coronary disease have been limited and shown mixed results, with some modest increases in preventive actions but inconsistent effects on cholesterol levels.
