Background technique Arteriosclerosis is one of the leading causes of death in developed countries. Some independent risk factors associated with arteriosclerosis include the presence of relatively high serum LDL cholesterol levels and relatively low serum HDL cholesterol levels in affected patients. Thus, some anti-atherosclerotic treatment regimens involve the administration of agents such as statins to reduce elevated serum LDL cholesterol levels. Agents that increase HDL cholesterol levels in a patient may also be used in anti-atherosclerotic regimens. It is believed that HDL cholesterol plays a major role in the...
