Despite significant improvement in the diagnosis and therapy of cardiovascular diseases their global risk and proportion of their clinical forms remains very high. Still the large part of the patients cannot reach the estimated target lipid levels despite statin therapy. Low adherence to preventive programmes with physical training and diet leads to progression of the pathological process of atherothrombosis. One possible therapeutic approach could be the combined hypolipidemic treatment. In this context we followed-up the size of lipoprotein particles among very high risk patients on statin monotherapy, where phytosterole was added. Lipoprotein profile among very high risk patients during combined therapy lead to improvement and therefore may contribute to lowering of their residual risk.
