What condition is characterized by the clogging of arteries due to plaque accumulation?

Atherosclerosis is characterized by the buildup of plaque within the artery walls, which can consist of cholesterol, fatty substances, cellular waste products, and calcium. This accumulation narrows arteries, reducing blood flow and increasing the risk of cardiovascular events such as heart attacks and strokes. The plaque formation is a progressive process, often starting with damage to the arterial wall due to risk factors like high cholesterol, smoking, or high blood pressure.

In contrast, hypertension refers to high blood pressure, which can contribute to the development of atherosclerosis but is not itself the condition characterized by plaque buildup. Cardiomyopathy involves the disease of the heart muscle itself, affecting the heart's ability to pump blood effectively and not directly related to arterial plaque. Angina is a symptom, typically experienced as chest pain due to reduced blood flow to the heart but does not specifically describe the underlying condition of plaque accumulation in the arteries. Therefore, atherosclerosis is the accurate term for the condition associated with the clogging of arteries due to plaque accumulation.
