Abstract
The metabolic syndrome is the constellation of adverse metabolic and clinical effects of insulin resistance. Its high and increasing prevalence and its profound impact on the major diseases of the western world require that clinicians consider its diagnosis and management on a routine basis. Recently published guidelines on its definition now make convenient and reliable diagnosis possible. Also, there is new and better understanding of the complex dyslipidemias and other risk factors strongly associated with the metabolic syndrome, which greatly increase the risk of clinical atherosclerotic events. Comprehensive clinical evaluation of these dyslipidemias and associated atherosclerosis risk factors can lead to their aggressive treatment, customized according to the circumstances of each patient. These steps are now more feasible and more clearly desirable than ever before. Statins alone greatly reduce atherosclerosis risk, but combination lipid therapy is often required for optimal dyslipidemia management and atheroprevention.
