What is peripheral artery disease (PAD)?

• A. A condition where atherosclerotic narrowing of the peripheral arteries reduces blood flow and oxygen delivery to the tissues.
• B. A disease of the heart valves.
• C. A venous disease.
• D. A neurological disorder.

Answer: (A)

PAD is a circulatory condition in which atherosclerotic plaques narrow the arteries outside the heart and brain, reducing blood flow to the limbs. That restricted flow means less oxygen reaches the muscles, especially during activity, so many people experience leg pain or cramping with walking (claudication). In more advanced stages, pain can occur at rest, wounds may heal poorly, and the legs can feel cold or weak. PAD signals broader atherosclerosis and raises risk for heart attack and stroke, so addressing risk factors like smoking, diabetes, high cholesterol, and high blood pressure is important. Treatments include supervised exercise, antiplatelet therapy, statins, and sometimes procedures to restore blood flow. The other options don’t fit because the condition described is not a heart-valve problem, a venous disease, or a neurological disorder.
