Advertisement. Atherosclerosis is a specific type of arteriosclerosis, but the terms are sometimes used interchangeably. Atherosclerosis refers to the buildup of fats, cholesterol and other substances in and on your artery walls (plaque), which can restrict blood flow.

"Cardio" refers to the heart, and "vascular" refers to all the blood vessels in the body. In comparison, heart disease is more specific and refers only to diseases of the heart, such as coronary artery disease, heart failure, heart valve abnormalities, and abnormal heart rhythms.

Arteriosclerosis (also known as cardiovascular arteriosclerosis) occurs when arteries grow thick and stiff and restrict blood flow to organs and tissues in the body. This gradual process, also known as hardening of the arteries, weakens arteries and can develop in various organs, most commonly the heart.

Cardiovascular disease (CVD) is a class of diseases that involve the heart or blood vessels. CVD includes coronary artery diseases (CAD) such as angina and myocardial infarction (commonly known as a heart attack).

The main structural difference between LDL and HDL is their compositions. ... Low-density lipoproteins contain proteins called B-100 proteins, while HDL particles contain mostly A-I and A-II proteins. The type of protein is significant because it determines the function of the lipoprotein particle.

Stable & Unstable Plaques Slowly growing plaques expand gradually due to accumulation of lipid in foam cells and migration and proliferation of smooth muscle cells. ... What makes an unstable plaque much more dangerous than a stable plaque? a. An unstable plaque has thicker arterial walls, which restricts blood flow.

Calcium deposits in the walls of arteries are part of the process of accumulating plaque, called atherosclerosis. The amount of calcium in artery walls is proportional to the amount of plaque present and is reported as a "calcium score."

Coronary artery disease (CAD) refers to blockages in the blood vessels that supply blood to the heart. PAD usually refers to blockages in the blood vessels that supply blood to the legs. The two conditions often occur together.

How Does High Cholesterol Cause Heart Disease? When there is too much cholesterol in your blood, it builds up in the walls of your arteries, causing a process called atherosclerosis, a form of heart disease. The arteries become narrowed and blood flow to the heart muscle is slowed down or blocked.

Is there a difference? The short answer is often no — health professionals frequently use the terms interchangeably. However, coronary heart disease , or CHD, is actually a result of coronary artery disease, or CAD, said Edward A. Fisher, M.D., Ph.

Hardening of the arteries (atherosclerosis) is a disorder in which arteries (blood vessels that carry oxygenated blood from the heart to other parts of the body) become narrowed because fat (cholesterol deposits called atherosclerosis) is first deposited on the inside walls of the arteries, then becomes hardened by ...

However, the two blood vessels are quite different from each other in terms of function. One of the major difference between arteries and veins is that the arteries carry oxygenated blood to all body parts, whereas veins carry the deoxygenated blood to the heart.

In this Article Atherosclerosis -- sometimes called hardening of the arteries -- can slowly narrow the arteries throughout your body. When atherosclerosis affects arteries that carry blood to the heart muscle, it's called coronary artery disease.

An accumulation of LDL in the arterial intima is an early step in atherosclerosis. Increased permeability of the endothelium and increased intimal retention of LDL appear to play an important role in this process. LDL particles interact with particular constituents of the intima, particularly the extracellular matrix.

Ischemia is when there is insufficient blood flow to the tissues and Infarction is when tissues start dying from a lack of blood supply.

There are two types: high-density lipoprotein (HDL) and low-density lipoprotein (LDL). As a general rule, HDL is considered “good” cholesterol, while LDL is considered “bad.” This is because HDL carries cholesterol to your liver, where it can be removed from your bloodstream before it builds up in your arteries.

Abdominal aortic calcification (AAC) is a marker of subclinical atherosclerotic disease and an independent predictor of subsequent vascular morbidity and mortality.
