Which condition is characterized by intermittent claudication?

Intermittent claudication is a condition that occurs when there is insufficient blood flow to the muscles, often due to a narrowing or blockage of the arteries, which is characteristic of peripheral artery disease (PAD). In individuals with PAD, physical activity, particularly walking or exercising, can cause pain and cramping in the legs due to inadequate blood supply. This pain typically subsides with rest, which is a hallmark feature of intermittent claudication.

In contrast, venous insufficiency primarily affects the veins and is related to issues with blood returning to the heart, leading to symptoms such as swelling and discomfort in the legs, rather than claudication. Coronary artery disease is focused on the arteries supplying the heart and can lead to chest pain or heart attacks, but does not specifically present with intermittent claudication. Deep vein thrombosis involves blood clots in the deep veins, which can cause swelling and pain, but again does not align with the specific symptoms associated with intermittent claudication. Therefore, peripheral artery disease is the correct condition associated with this characteristic symptom.
