What does peripheral artery disease entail?

Peripheral artery disease (PAD) specifically involves the narrowing or blockage of arteries that supply blood to the limbs, typically the legs. This condition is often caused by atherosclerosis, where fatty deposits build up in the artery walls, leading to reduced or obstructed blood flow. The result can include leg pain during activities such as walking or climbing stairs, as the muscles do not receive enough oxygen-rich blood.

Choosing the option that describes a partial or total blockage of an artery leading to limbs directly aligns with the definition and impact of PAD. It highlights the primary concern of this disease, which is its effect on peripheral circulation, particularly in the extremities. Understanding this condition's implications is crucial for recognition and potential treatment options.
