What is PAD primarily characterized by?

Peripheral Artery Disease (PAD) is primarily characterized by the blockage of leg arteries due to the buildup of plaque, which is formed from cholesterol, fat, and other substances. This progressive condition leads to stenosis, or narrowing, of the arteries that supply blood to the legs and is often associated with atherosclerosis. As a result, individuals with PAD may experience symptoms such as leg pain during walking (intermittent claudication) due to insufficient blood flow, as well as an increased risk of cardiovascular events.

The presence of plaque in the arteries limits blood flow, impacting overall circulation and often leading to complications if left untreated. Recognizing this characteristic is crucial for understanding the risks, management, and treatment options for those diagnosed with PAD.
