This document summarizes a study examining the effect of statin therapy on the progression of coronary artery calcification. The study found that patients treated with cerivastatin had a significantly lower median increase (8.8%) in coronary calcium scores compared to untreated patients (25% increase). Patients whose LDL cholesterol was reduced to under 100 mg/dl by treatment had an average decrease in calcium scores (-3.4%). The results suggest that statin therapy can slow the progression of calcification and underlying atherosclerosis. However, limitations include the open-label and prematurely ended nature of the study.
