Change in Coronary Plaque Volumes on Repeat CCTA in Patients With High and Low Lp(a)
| Lp(a) ≥70 mg/dL (n = 36) | Lp (a) <70 mg/dL (n = 125) | P Value | |
|---|---|---|---|
| Total plaque volume change | 128.2 ± 330.6 | 88.5 ± 312.2 | 0.508 |
| Calcific plaque volume change | 19.7 ± 69.7 | 1.0 ± 85.7 | 0.231 |
| Noncalcific plaque volume change | 108.5 ± 319.6 | 87.5 ± 288.6 | 0.708 |
| Low-density plaque volume change | 26.2 ± 88.4 | -0.7 ± 50.1 | 0.020 |
| Fibro-fatty volume change | 55.0 ± 242.8 | -25.0 ± 157.4 | 0.020 |
Values are mean ± SD of the absolute difference in plaque volume (mm3) between scan 1 and 2. Bold P values <0.05 show statistically significant differences.
CCTA = coronary computed tomography angiography; Lp(a) = lipoprotein(a).
