The purpose of this study was to determine the association between arterial inflammation, calcification and serological biomarkers in subjects with atherosclerosis, and to assess their therapeutic response to 12-week atorvastatin treatment. Methods: Forty-three statin-na?ve subjects with atherosclerosis received atorvastatin (40 mg/day) for 12 weeks and underwent 18F-FDG PET/CT, coronary calcification and abdominal adipose tissue volume measurements. A panel of serological biomarkers was analysed. Arterial inflammation was measured at seven arterial segments and normalized to venous FDG activity to produce target to background ratios (TBR). Thirty-four subjects without cardiovascular disease who repeated PET 1-4 years apart for routine health check-ups were retrospectively evaluated for comparison. Results: The baseline mean TBR values in atherosclerotic patients were positively correlated with age (R=0.36), body mass index (R=0.54), abdominal visceral adipose tissue volume (R=0.65), coronary calcification score (R=0.40), levels of low-density lipoprotein cholesterol (R=0.54), matrix metalloproteinase (MMP)-9 (R=0.46) and fatty acid binding protein 4 (FABP4) (R=0.67, all p<0.05). The TBR as well as high-sensitivity C-reactive protein (hsCRP), E-selectin, MMP-9, monocyte chemotactic protein 1, FABP4 and follistatin values were reduced significantly after the 12-week atorvastatin treatment. The TBR reduction marginally correlated with changes in MMP-9 levels (R=0.56, p=0.05). The control group, whose median age was younger, by comparison had lower hsCRP and arterial TBR than the subjects with atherosclerosis (all p<0.05), and moreover had a slight but insignificant increase in mean TBR at their 2.5±0.8 year follow-up. Conclusion: The medium dose of atorvastatin over a 12-week period resulted in a significant reduction of arterial inflammation as well as various circulating biomarkers. ? Springer-Verlag 2011. |
