Walking Leg Pain Can Signal Blocked Arteries

Peripheral artery disease, or PAD, develops when plaque narrows arteries, most often reducing circulation to the legs. A common sign is aching, cramping, discomfort or muscle fatigue that begins while walking and eases during rest. Some people have unusual symptoms or none at all. Others gradually walk less or skip stairs because the problem is mistaken for arthritis or aging. If PAD becomes severe, circulation to a leg may be suddenly interrupted, threatening both mobility and the limb.

PAD reflects the same disease process involved in heart attacks and many strokes, making leg symptoms a clue to wider cardiovascular risk. Smoking and diabetes are the strongest risk factors described. The burden falls disproportionately on lower-income populations, Indigenous peoples, underserved groups, and people in rural or remote communities. Obstacles including limited preventive care, food insecurity, long travel to specialists and delayed diagnosis can contribute to serious complications, including amputation. A simple, noninvasive test called the ankle-brachial index compares blood pressure at the ankle and arm, but access across Canada varies, especially in primary care.

The Canadian National Action Plan for Peripheral Artery Disease outlines six priorities: improving public knowledge, finding PAD sooner, strengthening treatment and care coordination, supporting Indigenous-led approaches, advancing research, and building advocacy. Proposed changes include training community health workers, backing mobile clinics directed by Indigenous communities and developing multidisciplinary PAD centers. After diagnosis, care can include smoking cessation, walking exercise, management of blood pressure, cholesterol and diabetes, and suitable low-cost medicines. More advanced disease may require a procedure to restore circulation. The plan aims to preserve mobility and quality of life while reducing preventable amputations and hospital stays and making vascular services more equitable.
