[Methodological problems of prevention/regression trials of atherosclerosis].
Animal models of atherosclerosis have improved our understanding of the pathogenic mechanisms involved in the formation of the atherosclerotic plaque. However, extrapolation of these data to the clinical situation is difficult. In addition, evaluation of the prevention or regression of atherosclerosis raises methodological problems. Although improved techniques provide a better evaluation of the extension of the plaques and their functional consequences, a number of points remain undecided: when to intervene, in which patients and how to extrapolate the results. A standardisation of the methods of evaluation of the atherosclerotic plaque is essential as is the fact that the benefit observed should be a reduction in cardiovascular complications and not simply the progression or regression of an angiographic lesion.
