What is Atherosclerosis?

When deposits of calcium, cholesterol, macrophages and several other lipids accumulate in the walls of arteries, it is known as atherosclerosis. These deposits are referred to as plaques. Atherosclerosis is basically a progressive chronic disease where in deposits of plaques are found on the walls of the arteries. These deposits cause several problems by protruding the artery which in later stage causes blockage to the flow of blood. Apart from this, plaques can cause sudden rupturing which can lead to blood clot and then occlusion of the artery. Arthrosclerosis also causes weakening of the walls of the arteries which form aneurysm in later stage. Sometimes the affected person might also have to face internal bleeding due to this. So the two main problems that people face due to arthrosclerosis are atheromatous plaques and aneurysm.  

These complications can get worse in advance stages and the disease become cumulative and difficult to treat. It may lead to infarction which is loss of tissues by the artery within 5 minutes. Another common scenario that is seen in many people is coronary thrombosis which can cause a heart attack or a heart stroke in worst cases. When the blood supply is not given sufficiently to the legs it causes claudication.
