Arteriosclerosis, literally meaning "hardening of the arteries", is an umbrella term for a vascular disorder characterized by abnormal thickening, hardening, and loss of elasticity [3] of the walls of arteries; [4] this process gradually restricts the blood flow to one's organs and tissues and can lead to severe health risks brought on by atherosclerosis, which is a specific form of ...
Atherosclerosis [a] is a pattern of the disease arteriosclerosis, [8] characterized by development of abnormalities called lesions in walls of arteries.This is a chronic inflammatory disease involving many different cell types and driven by elevated levels of cholesterol in the blood. [9]

For instance, due to atherosclerosis, the plaque would obstruct and causes ischaemia - the reduction of blood flow through the arteries. Ischaemia would then result in the decrease in oxygen supply to the heart, hence weaken the heart.
