Evaluation of: Puato M, Faggin E, Rattazzi M et al. Atorvastatin reduces macrophage accumulation in atherosclerotic plaques: a comparison of a nonstatin-based regimen in patients undergoing carotid endarterectomy. Stroke 41(6), 1163–1168 (2010).Statins have an established role in the treatment of hypercholesterolemia and the prophylactic treatment of patients with atherosclerotic disease, and have been found to prevent secondary cardiovascular events and thereby reduce morbidity and mortality. Nevertheless, the pathophysiologic effect of statins on inflammatory responses and local atherosclerotic plaque morphology in humans remains a matter of debate. In particular the question is unanswered whether statin-induced alterations in plaque composition can be ascribed to LDL lowering or an anti-inflammatory pleiotropic effect. We will discuss the results of a recent study by Puato et al. concerning the effect of two different atorvastatin dosages and a nonstatin lipid-lowering drug on atherosclerotic plaque morphology.
