[Lipid risk factors of atherosclerosis: who, when, how to treat?].

Hyperlipidemia, particularly hypercholesterolemia, is a well established risk factor for cardiovascular disease, specially coronary heart disease. Lipid-lowering therapies are associated with a reduction in cardiovascular morbidity and mortality in secondary as well as primary prevention. A precise lipid pattern is necessary before any treatment. The target level depends on the clinical data and associated cardiovascular risk factors. Diet is the first step approach and should always be continued. Cholestyramine and statins are the treatments of choice in case of hypercholesterolemia (type IIa). In case of isolated or associated hypertriglyceridemia (types IV and IIb) fibrates are the most efficient. No treatment is really efficient on Lp(a) level. A good observance is required for a lifelong treatment.
