Coronary artery disease (CAD) is more frequent among individuals with dysglycemia. Preventive interventions for diabetes can improve cardiometabolic risk factors (CRFs), but it is unclear whether the benefits on CRFs are similar for individuals at different genetic risk for CAD. We built a 201-variant polygenic risk score (PRS) for CAD and tested for interaction with diabetes prevention strategies on one-year changes in CRFs in 2,658 Diabetes Prevention Program participants. We also examined whether separate lifestyle behaviors interact with PRS on changes in CRFs in each intervention group. Participants in both the lifestyle and metformin interventions had greater improvement in the majority of recognized CRFs compared to placebo (P<0.001) irrespective of CAD genetic risk (P int>0.05). We detected nominal significant interactions between PRS and dietary quality and physical activity on one-year change in body mass index, fasting glucose, triglycerides, and HDLc in individuals randomized to metformin or placebo, but none of them achieved the multiple-testing correction for significance. This study confirms that diabetes preventive interventions improve CRFs regardless of CAD genetic risk, and delivers hypothesis-generating data on the varying benefit of increasing physical activity and improving diet on intermediate cardiovascular risk factors depending on individual CAD genetic risk profile.
