Which condition is specifically linked to the arteries and can be serious if untreated?

The condition specifically linked to the arteries and potentially serious if untreated is arteriosclerosis. This condition involves the thickening and hardening of the arterial walls, which can lead to reduced blood flow and increased risk of cardiovascular problems such as heart attacks and strokes. As arteries become less flexible and narrow, the heart has to work harder to pump blood, which can lead to further complications.

Arteriopathy, while it refers to disease of the arteries, is a more general term and could encompass various conditions affecting arterial health. Varicose veins pertain to venous issues rather than arterial problems, and phlebitis, which refers to inflammation of a vein, is also a venous condition. Thus, arteriosclerosis is the most directly associated with serious conditions linked to arterial health.
