What is atherosclerosis?

Plaque. buildup of plaque and cholesterol deposits, etc. in the arteries--- "hardening of the arteries". Risk factors--- smoking, family history, high cholesterol, high blood pressure, age.

What causes atherosclerosis?

Cholesterol Plaque. Atherosclerosis is the build up of cholesterol and calcium plaque in the arteries of the body. It is due to injury of the artery wall and inflammation which attracts blood cells which promote cholesterol deposition in the arteries. Known conditions which are associated with atherosclerosis include family history, smoking, hypertension, diabetes, elevated cholesterol/ldl or low hdl, and age. Read more...
White Blood Cells. An accumulation of white blood cells, mostly macrophages (called monocytes, one of 5 white blood cell types), which have invaded into the walls of the blood vessel to remove low density lipoprotein (fat carrying protein) particles. Macrophages die if overwhelmed with LDL & cannot export their ingested fat into high density lipoprotein particles. Cholesterol not best focus. Otherwise largely agree. Read more...
Multiple Factors. Atherosclerosis, also known as “hardening of the arteries”, occurs when areas of the artery wall thicken in response to either increased modifiable (high LDL particle levels, smoking or high blood pressure )and non-modifiable (genetics, age, gender) risk factors. Over time, areas of focal thickening may grow into a larger lesion called a “plaque" that can limit blood flow through the vessel. Read more...

What does atherosclerosis mean?

Plaque build up. It is hardening of the arteries, caused by fat, cholesterol, and other substances building up in the arteries - this is called plaque - making the arteries stiffer. This plaque interferes with the normal function of the arteries and can cause problems and symptoms throughout the body. The plaque can block the arteries and/or it can break off and flow to smaller vessels and block them. Read more...
Disease, Artery Wall. Atherosclerosis results from an accumulation of white blood cells, mostly macrophages (called monocytes, one of 5 white blood cell types), which have invaded into the walls of the blood vessel to remove low density lipoprotein (fat carrying protein) particles. The macrophages may die if overwhelmed with LDL & cannot export the ingested fat into high density lipoprotein particles. Read more...

What does atherosclerosis effect?

Artery wall. It affects the wall of arteries. Plaque builds up and can eventually block the artery resulting in symptoms such as chest pain if teh heart arteries are involved or stroke if it is the brain arteries. Factors such as a high cholesterol make the process more likely to occur. Read more...
Not a good thing! Atherosclerosis causes narrowing of blood vessels and result in poor blood flow to multiple organs most notably heart, brain, kidneys, intestines, limbs and eyes. This results in varying degrees of malfunction of these organs affecting quality of life and even threatening life. Read more...

What is atherosclerosis linked to?

Atherosclerosis. Atherosclerosis is a fancy name for disease of the arteries: risk factors are: genetics (your parents :-)), smoking, diabetes, high blood pressure, high cholesterol, obesity. There are other, secondary risks that are determined by specialized blood tests. Read more...
Lipoproteins, BG, BP. Age (older worse), sex (male worse), LDL and HDL lipoprotein (fat carrying protein) particle concentrations (not cholesterol per-se), blood glucose and blood pressure, along with smoking, obesity, inactivity, living longer (it typically starts in childhood), smoking, eating process foods (esp. High glycemic index foods), ongoing debate about fat (esp.Processed fat) in foods, etc. See nusi.Org. Read more...

What makes atherosclerosis dangerous?

The end result. Atherosclerosis is a progressive disease that involves all the arterial systems of the body, the brain, the heart, the kidneys, the gut and the limbs. As it progresses, it causes reduction of blood flow to these areas chronically, and the end organ becomes a target for embolization of the plaque or blood clot caused by atherosclerosis on an acute basis.

Loss/↓ Blood Supply. Disease is an accumulation of white blood cells in the wall of arteries, body wide, in response to which the artery walls enlarge (opening remains the same) ; thus asymptomatic for decades. Rupture of the endothelial cell lining layer allows plaque to contact blood, clots form ; showers of plaque ; clots fly downstream blocking smaller arteries, stopping blood flow with resulting tissue damage.

What is atherosclerosis and what makes it dangerous to you?

Common illness. Patches of macrophages loaded with cholesterol build up on the walls of arteries and cause problems, ranging from narrowing to clotting of the blood to occlusion to rupture. The epidemic peaked in 1968 but is still our leading cause of death. Read more...
Hardening/occlusion . Atherosclerosis is hardening of the artery by accumulation and building up plaque in its wall causing narrowing and occlusion of the artery and sometimes embolization which includes sending small clots or particles downstream with the end result of blocking blood to tissues and organs causing damages and death.

Progression&Rupture. Atherosclerosis is an accumulation of white blood cells in artery walls causing enlargement without symptoms (people don’t realize) for decades, until a plaque rupture (sudden) releases debris (embolization) into the blood & triggers clots which occlude the artery, either locally or downstream, with the end result of blocking blood to tissues/organs causing cell injury and death.

I was wondering what are atherosclerosis and arteriosclerosis?

Atherosclerosis. Atherosclerosis is a life long disease. It is generally at different stages at the same time in various vessels. For this reason taking care of diet, exercise and drug therapy to stop progression of the disease is crucial. Some areas won't be as helped as others but you may stop them from getting worse or at least slow the process down. Read more...

Hi doctors, was just wondering what is atherosclerosis aorta?

Fatty buildups. In young, healthy individuals the inner lining of the blood vessels is clean and smooth. Overtime, as part of the normal wear and tear, the inner surface of the blood vessels (including the aorta) may start becoming bumpy/lumpy due to fat (cholesterol) deposits called "atherosclerotic plaque". These fatty build ups also lead to hardening (calcium deposits) of the previously flexible vessel wall . Read more...
