PAD occurring in the legs is a serious disease that affects about 8 million people in the United States. A person's risk for PAD increases with age but can also be raised by smoking or having diabetes, high blood pressure, high cholesterol, or heart disease. Symptoms of PAD may include leg cramps or pain while walking, foot pain while resting, and skin wounds or ulcers on feet and toes. However, because only about one in three people with PAD knows to seek treatment for these symptoms, many end up with advanced disease that requires significant medical intervention, such as an endovascular or other surgical procedure to open the blocked arteries. While these procedures are helpful in treating people with severe PAD, lifestyle modifications and certain medications are also needed for long-term management of PAD and improved quality of life. An intensive combination of lipid modifying medications may be superior to standard lipid modifying medications in reducing PAD-associated risk factors and improving overall health in people with PAD. This study will compare the effectiveness of an intensive combination of lipid modifying medications versus standard lipid modifying medications in preventing blockages and re-narrowing of arteries in people with significant PAD who have had an endovascular intervention.
