摘要
Background The traditional primary prevention paradigm for coronary artery disease (CAD) centers on population-based algorithms to classify individual risk. However, this approach often misclassifies individuals and leaves many in the `intermediate' category, for whom there is no clear preferred prevention strategy. Coronary artery calcium (CAC) and poly-genic risk scoring (PRS) are 2 contemporary tools for risk prediction to enhance the impact of effective management. Aims To determine how these CAC and PRS impact adherence to pharmacotherapy and lifestyle measures in asymptomatic individuals with subclinical atherosclerosis. Methods The CAPAR-CAD study is a multicenter, open, randomized controlled trial in Victoria, Australia. Participants are self-selected individuals aged 40 to 70 years with no prior history of cardiovascular disease (CVD), intermediate 10year risk for CAD as determined by the pooled cohort equation (PCE), and CAC scores >0. All participants will have a health assessment, a full CT coronary angiogram (CTCA), and PRS calculation. They will then be randomized to receive their risk presented either as PCE and CAC, or PCE and PRS. The intervention includes e-Health coaching focused on risk factor management, health education and pharmacotherapy, and follow-up to augment adherence to a statin medication. The primary endpoint is a change in low-density lipoprotein cholesterol (LDL-C) from baseline to 12 months. The secondary endpoint is between-group differences in behavior modification and adherence to statin pharmacotherapy. Results As of July 31, 2021, we have screened 1,903 individuals. We present the results of the 574 participants deemed eligible after baseline assessment.
