What defines arteriosclerosis in the context of cardiovascular disease?

Arteriosclerosis refers primarily to the hardening or narrowing of the arteries, which is a critical aspect of cardiovascular disease. This condition is characterized by the thickening and stiffening of arterial walls due to various factors such as aging, high blood pressure, and cholesterol accumulation. Over time, this process can lead to reduced blood flow, increasing the risk of heart attacks, strokes, and other cardiovascular problems.

The essence of arteriosclerosis lies in the structural changes to the arteries, making them less elastic and more rigid, which hampers their ability to efficiently transport blood. Understanding this concept is vital as it highlights the fundamental ways in which cardiovascular health can be impacted by lifestyle and medical interventions.
