In an era dominated by the use of statins as agents to reduce cardiovascular risk, fibrates have been largely forgotten. This is despite a remarkably robust evidence base certifying to the cardioprotective effects of these agents. In the Helsinki Heart Study (HHS), a 5-year, double-blind, placebo-controlled trial of the effects of gemfibrozil in 4081 men aged 40 to 55 years who were free of clinically manifest CHD at entry to the study, there was a statistically significant 34% reduction in the incidence of total coronary events from 41.4 per 1000 in the placebo group to 27.3 per 1000 in the gemfibrozil group.1 In the Veterans Affairs High-Density Lipoprotein Intervention Trial (VA-HIT), a 5-year, double-blind, placebo-controlled trial with gemfibrozil in 2531 men with clinical CHD and low levels of both high-density lipoprotein (HDL) cholesterol and low-density lipoprotein (LDL) cholesterol, the primary end point (nonfatal myocardial infarction or death attributable to CHD) was reduced significantly by 22% from 21.7% in the placebo group to 17.3% in the gemfibrozil group.2 Positive results have also been obtained in angiographic studies with gemfibrozil in the Lopid Coronary Angiography Trial,3 with bezafibrate in the Bezafibrate Coronary Atherosclerosis Intervention Trial4 and with fenofibrate in the Diabetes Atherosclerosis Intervention Study.5

The cardiovascular benefits of treatment with fibrates appear to be greatest in people with insulin resistance and other features of the metabolic syndrome. In the HHS, a baseline level of serum triglyceride >200 mg/dL or a HDL cholesterol <40 mg/dL or a BMI >26 identified
