Abstract

Background - Previous studies have demonstrated that experimental hypercholesterolemia leads to neovascularization in the coronary artery vasa vasorum (VV). Recent evidence suggests that HMG-CoA reductase inhibitors (statins) have beneficial effects independent of lipid lowering. We aimed to determine the effect of simvastatin on coronary VV neovascularization, in the absence of cholesterol lowering. Methods and Results - Pigs were randomized to 3 groups fed a normal (N), high cholesterol (HC), or HC + simvastatin (HC+S) diet for 12 weeks. The proximal left anterior descending artery was isolated, scanned with micro-CT, and reconstructed. Quantification of the VV density in serial cross-sections along the vessel was then performed. LDL cholesterol was similarly increased in HC and HC+S compared with N. There was an increase in both VV density (4.7±0.3 versus 2.7±0.2 n/mm2; P2; P2; P2; P
