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

Statins don't directly clean out artery plaques. Instead, they lower cholesterol in the blood, which tells immune cells inside the plaque to stop multiplying.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.

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.
