Cholesterol management guidelines from the American College of Cardiology/American Heart Association Task Force have recently been published. See Table 1 for a brief summary of their recommendations.

Lipid-lowering drugs should be taken indefinitely; when they are stopped, plasma lipoproteins return to pretreatment levels. HMG-CoA reductase inhibitors (statins) remain the drugs of choice for treatment of most patients who require lipid-lowering therapy.

The FDA has approved the marketing of fenofibric acid (Trilipix - Abbott) to reduce triglycerides and increase HDL-C in patients with mixed dyslipidemia on optimal doses of a HMG-CoA reductase inhibitor (statin) who have, or have risk factors for, coronary heart disease. It is the first fibrate approved by the FDA specifically for combined use with a statin. Trilipix is also approved as monotherapy for hypertriglyceridemia, hypercholesterolemia and low HDL-C. The patent for Tricor, Abbott's older formulation of fenofibrate, will expire in 2011.

The FDA has approved the marketing of a second fixed-dose combination of extended-release niacin (Niaspan) with a generic statin. Niaspan/simvastatin (Simcor - Abbott) is approved for use in patients with hypercholesterolemia or mixed dyslipidemia (high LDL-cholesterol, low HDL-cholesterol and high serum triglycerides). Niaspan/lovastatin (Advicor) was marketed previously for the same indications.

A highly concentrated omega-3 polyunsaturated fatty acid (PUFA) preparation (Omacor - Reliant) has been approved by the FDA as an adjunct to diet for treatment of very high plasma triglyceride concentrations (>=500 mg/dL). Omacor is a combination of the ethyl esters of icosapentaenoic (EPA) and docosahexaenoic (DHA) acids. It is the first drug derived from omega-3 PUFAs to be sold by prescription.

Lipoprotein associated phospholipase A₂ (Lp-PLA₂), an enzyme involved in the repair of oxidative damage to lipoproteins, causes release of inflammatory mediators associated with atherosclerosis. A new assay, PLAC (diaDexus, Inc.), is now available to measure Lp-PLA₂ levels. C-reactive protein (CRP), another inflammatory mediator, appears to be a biomarker for coronary disease (MH Shishehbor et al, Cleve Clin J Med 2003; 70:634). The role of Lp-PLA₂ testing in determining cardiovascular risk is less clear.
