The drug reduced the number of inflammatory immune cells inside the artery plaques by nearly 40%, which also made the plaques less fatty and changed their collagen structure.

Atorvastatin Improves Plaque Stability in ApoE-Knockout Mice by Regulating Chemokines and Chemokine Receptors

Cohort Study

Animal

2014

The study found that a common cholesterol drug, atorvastatin, reduced harmful immune cells and fat buildup in mouse artery plaques, and also changed the collagen structure in a way that makes plaques less likely to rupture—exactly what the claim says.

Similar Assertions

The drug lowered the activity of enzymes that break down the structural fibers in plaques, which may help keep plaques from rupturing.

In mice prone to clogged arteries, a daily dose of atorvastatin made the dangerous, rupture-prone plaques much less common—even though the overall blockage didn’t get smaller.

The drug lowered levels of two key inflammation signals in the blood, showing it reduces body-wide inflammation even when cholesterol doesn’t change.

The drug lowered the levels of chemical signals (MCP-1 and CX3CL1) that attract immune cells to plaques, and also reduced the number of receptors on blood cells that respond to those signals.

Atorvastatin helps the support cells (pericytes) wrap around new blood vessels in plaques more tightly, making them stronger and less likely to leak.
