[Glitazones and atherosclerosis].
Atherosclerosis is a vascular disease, appearing early in life, and developing gradually and progressively, from the initial local inflammatory lesions, a stage at which endothelial dysfunction is already present, to the ultimate stage, culminating in atherosclerotic plaque rupture followed by thrombogenesis. Glitazones, specific agonists for the nuclear receptor PPARgamma, act at each stage of the atherogenesis process, and therefore are likely to convey cardioprotective activities in type 2 diabetic patients as well as in non-diabetic patients at high cardiovascular risk (glucose intolerant subjects with or without associated metabolic syndrome). In this review, we summarize the main stages of atherosclerosis progression and their pathophysiological mechanisms, and the results of studies carried out with glitazones, either in in vitro experimental models or in vivo in various animal models, as well as results of recent studies in type 2 diabetic patients, which support the concept for a cardioprotective action of glitazones.
