This paper reviews the clinical trial data that offer insight into the question of whether, and in what groups of people, triglycerides might be an appropriate therapeutic target for the primary or secondary prevention of atherosclerotic cardiovascular disease. Two angiographic trials (the Lopid Coronary Angiography Trial and the Bezafibrate Coronary Atherosclerosis Intervention Trial) and three clinical endpoint trials (the Helsinki Heart Study, the Bezafibrate Infarction Prevention Study, and the VA HDL Intervention Trial) are reviewed. Hypertriglyceridemia per se is probably not an appropriate therapeutic target for the prevention of atherosclerotic cardiovascular disease because it is a poor marker of atherogenic risk and because there have been no clinical trials that have directly addressed the question of whether lowering the triglyceride level reduces the number of clinical events. The studies reviewed here, however, suggest that patients with established coronary heart disease and a high triglyceride level, in association with either a low high-density lipoprotein-cholesterol level or perhaps other features of the metabolic syndrome, such as obesity, diabetes, or hypertension, may benefit from fibrate therapy. For patients without established coronary heart disease, it is reasonable to consider hypertriglyceridemia as a risk marker prompting the aggressive treatment of other risk factors such as hypertension, diabetes, high low-density lipoprotein-cholesterol, and obesity.

Epidemiologic studies have consistently implicated low plasma high-density lipoprotein cholesterol as an important, independent risk factor for the development of coronary heart disease. However, clinical trials specifically designed to evaluate the role of lipid therapy in patients with low high-density lipoprotein cholesterol have only been recently reported. They include two trials with angiographic end points, the Lopid Coronary Angiography Trial and the Bezafibrate Coronary Atherosclerosis Intervention Trial, and three clinical end points trials, the Air Force/Texas Coronary Atherosclerosis Prevention study, the Department of Veterans Affairs High-Density Lipoprotein Intervention Trial, and the Bezafibrate Infarction Prevention study. These and other trials clearly indicate that persons with coronary heart disease and high low-density lipoprotein cholesterol (>130 mg/dL [3.36 mmol/L]), with or without low high-density lipoprotein cholesterol, benefit from statin therapy. The Air Force/Texas Coronary Atherosclerosis Prevention study showed that persons at high risk of coronary heart disease but without known disease, who have moderate levels of low-density lipoprotein cholesterol as well as low levels of high-density lipoprotein cholesterol, also appear to benefit from statin therapy although the cost effectiveness of this approach is unclear. The results from the Department of Veterans Affairs High Density Lipoprotein Intervention Trial provide convincing evidence that patients without high low-density lipoprotein cholesterol and with established coronary heart disease and low high-density lipoprotein cholesterol benefit from gemfibrozil. This drug may be particularly beneficial for patients who, in addition to low high-density lipoprotein cholesterol, present with other features of the metabolic syndrome, such as obesity, glucose intolerance, and high triglycerides. Whether other fibrates, niacin, or statins lower coronary heart disease risk in persons with low high-density lipoprotein cholesterol in the absence of high or moderately high low-density lipoprotein cholesterol is unknown.

Patients with the metabolic syndrome and/or Type 2 diabetes mellitus continue to have a high risk of coronary heart disease (CHD) and progression of atherosclerotic lesions despite aggressive statin therapy. Although the National Cholesterol Education Programme Adult Treatment Panel III guidelines recommend the use of fibrates in combination with statins in patients at very high risk of CHD (e.g., patients at the low-density lipoprotein cholesterol target with high triglycerides and low high-density lipoprotein cholesterol, many physicians remain reluctant to use these combinations due to concerns of myotoxicity. Recently conducted metabolic and pharmacokinetic drug-drug interaction studies using gemfibrozil or fenofibrate in combination with five commonly used statins demonstrated a widely different drug interaction potential for these two fibrates. Gemfibrozil causes a 2- to 6-fold increase in statin area under the curve and increases the exposure to many recently approved drugs for the treatment of diabetes. Alternatively, fenofibrate does not adversely affect either the metabolism or pharmacokinetics of the statins studied. These pharmacokinetic differences appear to translate into less potential for interactions with fenofibrate/statin combination therapy compared to gemfibrozil/statin co-administration. The Action to Control Cardiovascular Risk in Diabetes (ACCORD) study in 10,000 patients with Type 2 diabetes mellitus is testing the efficacy and safety of fenofibrate/statin combination.
