Coronary Plaque Burden Median (25–75th Percentile) [1–99th Percentile] | Model 1 Effect Size (95% CI, P Value) | Model 2 Effect Size (95% CI, P Value) | |||
---|---|---|---|---|---|
Low PRS (n=329) | Average PRS (n=987) | High PRS (n=329) | |||
CACS | 0 (0–21) [0–841] | 0 (0–85) [0–2565] | 18 (0–178) [0–2122] | +81% (+63% to +101%, P=2.0e‐27) | +78% (+60% to +98%, P=4.1e‐26) |
Segment stenosis score | 0 (0 to 1) [0 to 19] | 1 (0 to 4) [0 to 25] | 2 (0–7) [0–26] | +29% (+23% to +34%, P=1.5e‐30) | +16% (+11% to +21%, P=2.4e‐29) |
The effect size corresponds to the change in % in the geometric mean of the variable per SD increase in the PRS. Model 1 was adjusted for age, sex, the first 4 principal components of ancestry, as well as an interaction term between age and sex. Model 2 was further adjusted for antihypertensive treatment, lipid‐lowering treatment, body mass index, symptoms, and active smoking. CACS indicates coronary artery calcium score; PRS, polygenic risk score.
