Authors' conclusion

In asymptomatic, intermediate-risk individuals, statin treatment was associated with a shift toward higher density calcium within coronary plaques, most marked with effective lowering of LDL-C. (Coronary Artery Calcium Score: Use to Guide Management of Hereditary Coronary Artery Disease [CAUGHT-CAD]; ACTRN12614001294640).

Primary result

As reported in the abstract

Per-lesion level change in volumes of calcified plaque subtypes
Intermediate-density calcium, greater progression; SE = 0.39
β 0.89; P = 0.02
High-density calcium, greater progression; SE = 0.24
β 0.79; P = 0.001
Noncalcified plaque, regression; SE = 1.64
β −9.83; P < 0.001
