Atherosclerosis is defined as an occlusive disease of the vasculature that occurs as a result of the deposition of lipid-laden plaques, and arteriosclerosis is defined as nonocclusive remodeling of the vasculature accompanied by a loss of arterial elasticity. Atherosclerosis stages: healthy artery, plaque formation, and thrombosis in flat style isolated on white background. Create an account to start this course today. All arteries are susceptible to atherosclerosis, but the aorta, coronary and carotid arteries are affected most. The earliest lesion is the fatty streak. The fatty streak phase alone does not cause any noticeable symptoms but can progress into a more dangerous phase of atherosclerosis called a fibrous plaque. "-sclerosis" means hardening or loss of elasticity of a blood vessel. As the final treatment for atherosclerotic disease is not established yet, however, action is need in preventing the disease onset.

Researches have proved that there are three different stages of atherosclerosis, although the specific pathological development of atherosclerosis is not well known yet. Coming back to atherosclerosis, the first of stages of atherosclerosis is the formation of the fatty streak on the endothelial lining (inner layer) of the arteries. New imaging techniques such as intravascular ultrasound or IVUS have made possible to investigate atherosclerosis in early stages. Foods high in cholesterol will in turn cause buildup in the arteries. Atherosclerosis is a disease in which the wall of the artery develops abnormalities, called lesions.These lesions may lead to narrowing due to the buildup of atheromatous plaque.

Atherosclerosis is a disease of blood vessels which develops over years and involves the progressive development of a fibrofatty lesion, termed an atheromatous plaque, within the vascular wall. Atherosclerosis has three stages that increase in severity and danger as they progress. This stage is chronic and progress slowly, as many factors contribute in its development (cumulative process). Atherosclerosis: disease of large and medium-sized arteries characterized by endothelial dysfunction, vascular inflammation and accumulation of lipids, cholesterol, calcium and cellular debris within the intima of the vessel wall. • Atherosclerosis is a preventable and treatable condition.
