Atherosclerosis is a type of arteriosclerosis. The name comes from the Greek words athero (meaning gruel or paste) and sclerosis (hardness). It is a process of formation of plaque inside the wall of blood vessel. Plaque is collection of fatty substances, cholesterol, cellular waste products, calcium and fibrin (a clotting material in the blood). When person gets old, process of atherosclerosis starts. Thickening of blood vessels is called atherosclerosis. So far we have just talked about thickening of vessels.

Now what next, plaque can undergo following changes. Either bleeding (hemorrhage) into the plaque , blood enters into wall of blood vessel, thus it gets more thickened and block the vessel or plaque gets damage and platelet(Cells which helps in clotting process) comes and aggregate on the plaque where it damages. Thus causing more narrowing of vessel. We were talking about blood pressure causing atherosclerosis. Yes, it is main risk factor. Actually it is high blood pressure which causes injury to these plaques, so after injury to these plaques, platelet comes to injured areas and further narrow the blood vessels.Because of the damage, over time fats, cholesterol, platelets, cellular debris and calcium are also deposited in the artery wall. These substances may stimulate the cells of the artery wall to produce still other substances like smooth muscles. This results in more cells accumulating in the innermost layer of the artery wall where the atherosclerotic lesions form. These cells accumulate |
