How statins shrink artery gunk without touching it
Inhibition of macrophage proliferation dominates plaque regression in response to cholesterol lowering

Surprising Findings
Atorvastatin doesn’t accumulate in plaques—even in mice or humans taking high doses.
Everyone assumed statins acted directly on plaque cells. This study proves they work indirectly—through blood cholesterol levels—making their effect more systemic and less targeted than thought.
Practical Takeaways
Stick with your statin—even if you feel fine. It’s not removing plaque, but it’s stopping immune cells from multiplying inside it, making plaques more stable and less likely to rupture.

Statins do not induce significant regression of established atherosclerotic plaque but reduce plaque progression and enhance plaque stability by lowering LDL cholesterol exposure to arterial walls.
When people with clogged arteries have lower bad cholesterol in their blood, the immune cells inside the plaque stop multiplying as much, which helps shrink the plaque.
In mice with clogged arteries, lowering cholesterol makes the immune cells inside the plaque stop multiplying, which is why the plaque gets smaller — not because fewer cells come in or leave.
The more fat and cholesterol packed inside a person’s artery plaque, the more the immune cells inside it are dividing — suggesting the fat itself is fueling their growth.
The cholesterol-lowering drug atorvastatin doesn’t get into the fatty plaques in arteries — so it must be working by lowering cholesterol in the blood, not by directly touching the immune cells inside the plaque.
