title: Approach to lipid therapy in the patient with atherosclerotic vascular disease.
abstract: Hyperlipidemia increases the incidence of atherosclerotic vascular disease and is associated with greater rates of recurrent cardiovascular events among individuals with established vascular disease. Several large population studies have confirmed the link between all cholesterol components (including elevated low-density lipoprotein [LDL] cholesterol, total cholesterol, and triglyceride levels, and reduced high-density lipoprotein [HDL] levels) with coronary heart disease and other manifestations of systemic atherosclerosis. In addition, landmark clinical trials have clearly established that lowering LDL cholesterol levels with statins (HMG-CoA reductase inhibitors) can lower recurrent cardiovascular events by nearly 25%. The benefits of altering non-LDL cholesterol levels (eg, triglycerides and HDL) are less clear, but several other medications are often used in conjunction with statins for cholesterol lowering. First-line therapy for lipid lowering in patients with atherosclerotic vascular disease includes statins and a recommendation for lifestyle changes (including diet and exercise). Second-line options for lowering cholesterol include fibrates, nicotinic acid, bile acid sequestrants, and ezetimibe. Therapeutic goals for patients with vascular disease are to achieve an LDL cholesterol level < 100 mg/dL, or <70 mg/dL in individuals at particularly high risk.
