Which condition is characterized by the build-up of plaque in the arteries?

Atherosclerosis is characterized by the build-up of plaque in the arteries, which is a condition that can lead to significant cardiovascular issues. Plaque mainly consists of fat, cholesterol, and other substances found in the blood. Over time, this accumulation narrows the arteries and restricts blood flow, increasing the risk of heart attacks and strokes.

In contrast, arteriosclerosis refers to the general stiffening or hardening of arteries, which can be a result of atherosclerosis but does not specifically denote plaque build-up. Hypertension is high blood pressure, a separate condition that can be influenced by many factors, including atherosclerosis but is not defined by plaque accumulation. Angina refers to chest pain that occurs when the heart does not get enough blood, often as a result of atherosclerosis but not a condition characterized by plaque itself.

Thus, recognizing atherosclerosis as the specific condition defined by the presence of plaque in the arteries is crucial for understanding how it relates to overall health and the risk of cardiovascular diseases.
