A lot of shocking pressure develops due to tapering and growing hard of the arteries. This progressive course of action gradually and silently blockades arteries which puts blood stream in danger. This disease is known as atherosclerosis.
Atherosclerosis is the normal reason of strokes, heart attacks and minor vascular disease. These are collectively called “cardiovascular disease.” In the year 2005 more than 800,000 people died in America.
Causes of Atherosclerosis:-
As per the views expressed by Richard Stein, MD, national speaker for the American Heart Association, this disease begins due to injury of the endothelium for smoking, high cholesterol or high blood pressure. At such point, cholesterol plaque development starts.
Cholesterol attack. Bad cholesterol or LDL crosses injured endothelium. The cholesterol comes into the wall of the artery.
Plaque development. White blood cells flow in to absorb the LDL cholesterol. Over years, the heaping up mess of cholesterol and cells turns into a plaque in the wall of the artery.
Atherosclerosis and Plaque Attacks:-
Plaques from atherosclerosis can act in various ways.
· Plaques can unexpectedly crack, allowing blood to thicken within an artery. When this happens in the brain it is called a stroke and when it is in the heart, it is a heart attack.
· They can live inside the artery wall where the plaque develops to a definite size and stops. Mr. Stein states that these plaques may by no means grounds any indications as they do not oppose blood flow.
· They can develop in a slow, guarded way into the path of blood flow. Ultimately, they bring about important obstacles. The normal sign is ache on exertion (in the legs or chest).
The plaques of atherosclerosis may cause the following cardiovascular disease:
- Cerebrovascular disease: Cracked plaques in the brain’s arteries are the reason of strokes, with the possibility for stable brain damage. Interim obstructions in an artery can also be the reason of transient ischemic attacks (TIAs), which are the caution signs of stroke; though, there is no brain damage.
- Coronary artery disease: Constant plaques in the heart’s arteries are the reason of angina. Unexpected plaque crack and clotting causes heart muscle to expire. This is a myocardial infarction or a heart attack.
