Niacin in Patients with Low HDL Cholesterol Levels Receiving Intensive Statin Therapy

In this clinical trial involving patients with established cardiovascular disease, the addition of niacin to intensive statin therapy provided no additional clinical benefit over a period of 3 years, despite favorable changes in lipid levels. More than 18 million North Americans have coronary heart disease, and despite profound advances in both pharmacologic and interventional management, both morbidity and mortality remain appreciable. 1 , 2 Elevated low-density lipoprotein (LDL) cholesterol levels are an established predictor of the risk of coronary heart disease. Multiple primary and secondary prevention trials have shown a significant reduction of 25 to 35% in the risk of cardiovascular events with statin therapy 3 ; however, residual risk persists despite the achievement of target LDL cholesterol levels. Epidemiologic studies have shown that, in addition to elevated LDL cholesterol levels, low levels of high-density lipoprotein (HDL) cholesterol . . .
