Lipid-lowering update 2001. Aggressive new goals.

OBJECTIVE

To review the central role of cholesterol in coronary artery disease (CAD), underscore the need for identifying patients at high risk of CAD, and discuss treatment of dyslipidemias.

QUALITY OF EVIDENCE

Current literature (1995-2000) was searched via MEDLINE using the MeSH headings "cholesterol," "risk reduction," and "statins." Recommendations in this paper are based mainly on the results of large randomized controlled trials. Preference was given to more recent articles, clinically relevant articles, and landmark clinical trials.

MAIN MESSAGE

Lipid lowering, and specifically low-density lipoprotein lowering, has been repeatedly shown in large clinical trials to improve survival dramatically and reduce cardiac events in both primary and secondary prevention. Identifying those at highest risk for future cardiac events is critical because these patients will benefit most from aggressive modification of risk factors. The definition of high risk has been expanded to include patients with diabetes mellitus and peripheral vascular disease, as well as those with established CAD. A full lipid profile is required for these patients to assess risk and develop a lipid-lowering strategy with proven effectiveness.

CONCLUSION

With the advent of powerful, efficacious, and well tolerated cholesterol-modifying therapies, lipid normalization should be a mandate for all physicians caring for patients with established CAD and patients at risk of developing CAD.
