Update on lipid-lowering therapy and LDL-cholesterol targets.

摘要

Serum cholesterol has long been recognized as an important risk factor for the development and progression of atherosclerotic vascular disease. For more than 30 years, improved outcomes with lipid lowering have been demonstrated. As a result of these data, the National Heart, Lung, and Blood Institute (NHLBI) convened the National Cholesterol Education Program-Adult Treatment Panel I (NCEP ATP I). This panel and similar ones around the world have served to set the standards for lipid lowering in clinical practice. Subsequent revisions of these standards (NCEP ATP II and III) have led to greater focus being placed on LDL, and targets for lowering LDL levels being based on patients' risk of subsequent coronary disease events. Since the publication of the NCEP ATP III guidelines, several large-scale clinical trials of cholesterol lowering have been conducted, the findings of which have the potential to impact on clinical practice standards. In this article we focus on current guidelines for lipid-loweringtherapy, review the results and implications of important completed clinical trials, and consider the utility of additional targets for preventive therapy, such as C-reactive protein and HDL. We also consider the prospects for treatments in development and future goals.
