Triglycerides: risk factor or fellow traveler?

An unresolved issue in preventive cardiology is whether the serum triglyceride level is an independent risk factor for coronary heart disease and, as a direct practical consequence, whether it has value as a diagnostic test. Evidence published in the past year has contributed substantially to clarifying these issues. In this review, we discuss the data that bears upon the importance of triglycerides as a risk factor and the implications of recent clinical trials directed at lipid lowering. We then discuss the alternatives for triglyceride lowering therapy in the light of this new knowledge. (C) 2001 Lippincott Williams & Wilkins. Inc.
