title: The role of fibric acid derivatives in the secondary prevention of coronary heart disease.
abstract: Fibric acid derivatives effectively lower triglycerides and raise high-density lipoprotein (HDL) cholesterol, but their effect on low-density lipoprotein (LDL) cholesterol is weakly beneficial (small decreases) to adverse (small increases) and varies according to the triglyceride level. Early primary prevention studies of atherosclerosis using the fibric acid derivative clofibrate showed only modest effects on atherosclerosis and an alarming increase in mortality in the intervention group. Although the Helsinki Heart Study later demonstrated that gemfibrozil decreased cardiac endpoints in primary prevention without increasing total mortality, the efficacy of fibric acid derivatives in both primary and secondary prevention of atherosclerosis has remained widely in doubt. Nevertheless, many patients with atherosclerosis have normal or even low LDL cholesterol, but elevated triglyceride, and low HDL cholesterol; furthermore, even aggressive LDL cholesterol lowering with HMG Co-A (3-hydroxy 3-methylglutaryl coenzyme A) reductase inhibitors (statins) fails to prevent the majority of atherosclerotic events. These findings have kindled increased interest in the use of fibric acid derivatives in atherosclerosis prevention, especially through treatment of non-LDL dyslipidemias. Recent studies with angiographic and clinical end-points have now provided evidence for a beneficial effect of at least some drugs in this class in the secondary prevention of atherosclerosis.
