What is the term used to describe inflammation of the arteries?

The term used to describe inflammation of the arteries is arteritis. This condition can lead to various complications, including arterial dysfunction and associated symptoms due to compromised blood flow. Arteritis can be caused by several factors, including autoimmune diseases, infections, or other inflammatory conditions. This distinguishes it clearly from the other terms provided.

Atherosclerosis refers to the buildup of plaque within the arterial walls, leading to narrowed arteries and potential cardiovascular issues, but it does not specifically denote inflammation.

Angina typically describes chest pain that occurs when the heart does not receive enough blood and oxygen, often due to coronary artery disease, rather than inflammation of the arteries themselves.

An aneurysm is an abnormal bulge or ballooning in the wall of an artery, which can result from weaknesses in the vessel wall, but it too does not specifically indicate inflammation. Therefore, the focus on inflammation makes arteritis the correct term in this context.
