Hypothesis
Plaque characteristics illustrate marked heterogeneity with both plaque regression and progression as lipid lowering therapy is instituted.
Conclusion
In statin-naive patients, lipid-modulating agents have initial paradoxical effects on lumen size, with significant changes in plaque composition observed.
Supporting Evidence
- 39 out of 42 plaques were successfully imaged.
- 53.5% of plaques demonstrated progression while 46.5% showed regression.
- Significant decreases in outer wall area and vessel wall area were observed in regressing plaques.
Takeaway
This study looked at how cholesterol-lowering medications affect plaque in arteries, finding that sometimes the size of the artery's opening can get smaller even when the plaque itself is decreasing.
Methodology
CMR was used to analyze 42 complete bilateral human plaques for changes in plaque morphology before and after lipid-lowering therapy.
Participant Demographics
Participants were statin-naive patients with advanced carotid disease, average age 68 years.
