Proceeding from the obtained data, the authors conclude that two factors are of paramount importance in the pathogenesis of atherosclerosis: 1) lipid infiltration, 2) fibrin and platelets deposits on the vascular wall. It seems hardly proper to oppose the lipid-infiltrationab of pathogenesis of atherosclerosis to the thrombogenic one, since they do not necessarily exclude one another. Moreover, they seem to present two aspects of a single process: on the one hand, lipids increase platelet adhesion and aggregation on the vascular wall; on the other hand, platelets during aggregation help the penetration of beta-lipoproteins into the arterial wall by increasing the permeability of the endothelium and by adsorbing cholesterol-rich beta-lipoproteins on their own surface. A vicious circle occurs that must underly one of the mechanisms of the atherosclerosis development. |
