Statins don’t remove existing gunk in arteries, but they stop more gunk from building up and make existing gunk less likely to break open.

MRI-measured regression of carotid atherosclerosis induced by statins with and without niacin in a randomised controlled trial: the NIA plaque study
This study found that taking statins actually made existing artery plaque shrink, not just slow down its growth—exactly the opposite of what the claim says. So the claim is wrong: statins can reduce plaque, not just stop it from getting worse.
Inhibition of macrophage proliferation dominates plaque regression in response to cholesterol lowering
This study shows that statins help shrink dangerous artery plaques by cutting down LDL cholesterol, which stops immune cells in the plaque from multiplying too much — meaning the plaques become smaller and safer over time.
This study found that a statin medicine made dangerous artery plaques more stable without lowering cholesterol levels, which matches the claim that statins help plaques become less likely to break open—not by shrinking them, but by making them safer.
