The Study
Statin-Induced Cholesterol Lowering and Plaque Regression After 6 Months of Magnetic Resonance Imaging–Monitored Therapy
This study watched 27 people who were already taking statins and saw that their artery gunk went down a little after six months, and their bad cholesterol also went down. But it didn't compare them to people who didn't take statins, so we can't say for sure the statins caused the change.
Analysis score
Maximum 72 for a cohort study.
Where the score came from
Doctors gave people with clogged arteries a medicine called simvastatin for 6 months and used a special MRI to see if the gunk in their arteries shrank.

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.
Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — this shows that statins can start cleaning arteries faster than previously thought, and the cleaner the blood, the more the clogs shrink.
- 2The gunk (plaque) shrank by 12%, and bad cholesterol (LDL) dropped by 23%.
- 3The more LDL dropped, the more the gunk shrank.
- 4The artery also got a tiny bit wider.

Taking simvastatin at 20–80 mg per day for six months lowers LDL cholesterol by about 23% in people with atherosclerosis, and does not change HDL cholesterol or triglyceride levels.
After six months of statin therapy, people who experience a greater decrease in LDL cholesterol also tend to have a larger increase in the internal diameter of their aorta.
In adults with atherosclerosis, taking simvastatin for six months at doses of 20–80 mg daily is linked to a 12% decrease in aortic plaque volume and a 23% decrease in LDL cholesterol, with greater LDL reduction corresponding to greater plaque reduction.
MRI scans show that statin therapy reduces aortic plaque in six months, whereas earlier imaging methods required at least twelve months to detect the same reduction.
Combined transesophageal and surface MRI can measure changes in aortic plaque volume with 4.8% precision, allowing detection of plaque reduction as early as six months after starting statin therapy.
High levels of LDL cholesterol by themselves do not lead to the buildup of plaque in arteries or to heart disease.
