Which condition is characterized by poor circulation?

Peripheral vascular disease (PVD) is specifically characterized by poor circulation, particularly in the limbs. This condition occurs when the blood vessels that supply blood to the arms and legs are narrowed or blocked, leading to reduced blood flow. PVD can result in symptoms such as pain, cramps, and fatigue in the affected limbs, especially during physical activity.

One of the key aspects of PVD is that it directly affects the peripheral arteries, which are critical for delivering oxygen-rich blood to the extremities. The inadequate blood flow associated with PVD can cause damage over time to the muscles and tissues in the legs and feet, potentially leading to complications like ulcers, infections, or even gangrene if not properly managed.

In contrast, arteriosclerosis refers to the thickening and hardening of the arterial walls, which can contribute to poor circulation but isn't limited to the peripheral vessels alone. Angina is a type of chest pain associated with reduced blood flow to the heart muscle itself, and a cerebrovascular accident, or stroke, involves sudden issues in brain circulation, again not directly related to poor limb circulation in the way that PVD is. Therefore, PVD is accurately described as a condition characterized by poor circulation in the context of the question.
