Leg Pain May Signal Peripheral Artery Disease, an Underrecognized Vascular Threat

Peripheral artery disease occurs when plaque narrows arteries, most often in the legs, causing pain during walking that eases with rest. It shares a disease process with heart attacks and strokes, and severe blockages can suddenly cut off blood flow to a limb. The article says PAD disproportionately affects smokers, people with diabetes, lower-income, rural, Indigenous and underserved groups, and a Canadian action plan aims to improve awareness, diagnosis, treatment, Indigenous-led care, research and advocacy.

Peripheral artery disease develops when fatty plaque narrows arteries, usually in the legs. Walking may bring cramping or fatigue that improves with rest, yet some patients notice little or nothing. Severe narrowing can abruptly halt limb blood flow.

The condition reflects the same vascular process behind heart attacks and strokes. Risk falls heavily on smokers and people with diabetes, as well as lower-income, rural, Indigenous and other underserved communities. A Canadian plan targets awareness, earlier diagnosis, treatment pathways, Indigenous-led care, research and advocacy.
