This research aims to enhance coronary artery disease risk prediction by integrating conventional risk factors, polygenic scores, and proteomics.
Data from UK Biobank was used, including participants with plasma proteomics and genetic risk data after excluding prevalent CAD.
Participants were divided into training (n=32,330) and validation (n=13,857) sets, with an external validation set from Scotland/Wales (n=5,775).
A proteomic risk score was derived using Cox regression and models trained with conventional and incremental risk factors.
Integrating polygenic risk scores and proteomic data improved the AUC for CAD prediction from 0.750 to 0.789 in internal validation (95% CI).
External validation showed an AUC increase from 0.717 to 0.762 (95% CI) when including additional risk factors.
A 9-protein panel was identified that captured most predictive information related to CAD risk.
