Which condition is most likely indicated by pain in the leg that occurs with walking and is relieved by rest, with cool extremities and reduced pulses?

• A. Chronic Arterial Insufficiency
• B. Chronic Venous Insufficiency
• C. Chronic Unstable Angina
• D. Chronic Coronary Artery Disease

Answer: (A)

The main concept is leg pain caused by insufficient arterial blood flow during exercise, known as claudication from peripheral arterial disease. When you walk, the leg muscles demand more oxygen, and if the arteries are narrowed, the blood supply can’t keep up, causing ischemic pain. Rest reduces the muscle’s workload, so the pain eases. Cool extremities and weak or absent pulses point to reduced arterial inflow from an occlusive process, typically atherosclerosis.

This isn’t consistent with venous problems, which usually produce aching, heaviness, edema, or skin changes and are worsened by standing and relieved by leg elevation, with pulses typically present. It also isn’t a cardiac condition; unstable angina or chronic coronary artery disease cause chest pain from myocardial ischemia, not leg pain associated with walking.
