There has been much published data on the effect of lipid lowering drugs or statins (HMG-Co A reductase inhibitors) and plaque regression (Corti,2001, 2005, Lima J, 2004). These trials demonstrated a significant reduction in the amount of plaque within the vessel wall as well as the reduction of LDL-cholesterol. A recently published randomised placebo-controlled trial (METEOR) (Crouse J, 2007)showed that rosuvastatin 40mg once daily over 2 years arrested carotid plaque progression which continued in the placebo group. This study was was highly significant (P<0.01). In this study, carotid plaque and carotid intima media thickness (CIMT) was assessed by B-mode ultrasound. Such studies prove that there is a benefit of using statins in those with low risk or who have established plaque disease.
