What means arteriosclerosis?
Definition of arteriosclerosis : a chronic disease characterized by abnormal thickening and hardening of the arterial walls with resulting loss of elasticity — compare atherosclerosis.
What are the different types of arteriosclerosis?
The three main types of arteriosclerosis include:
- Atherosclerosis: In this type, the large arteries are hardened and narrowed.
- Moenckeberg medial calcific sclerosis: The hardening of small to medium-sized arteries.
- Arteriolosclerosis: The calcification of small arteries.
What is pathophysiology of atherosclerosis?
Atherosclerosis is the pathologic process of lipid accumulation, scarring, and inflammation in the vascular wall, particularly the subendothelial (intimal) space of arteries, leading to vascular wall thickening, luminal stenosis, calcification, and in some cases thrombosis.
What distinguishes atherosclerosis from arteriosclerosis?
Arteriosclerosis is a broader term for the condition in which the arteries narrow and harden, leading to poor circulation of blood throughout the body. Atherosclerosis is a specific kind of arteriosclerosis, but these terms are often used interchangeably.
What’s the main artery called?
aorta
The largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.
What are 8 risk factors of CAD?
Risk factors for coronary artery disease include:
- Age. Getting older increases your risk of damaged and narrowed arteries.
- Sex. Men are generally at greater risk of coronary artery disease.
- Family history.
- Smoking.
- High blood pressure.
- High blood cholesterol levels.
- Diabetes.
- Overweight or obesity.
What are the 5 stages of atherosclerosis?
Atherogenesis can be divided into five key steps, which are 1) endothelial dysfunction, 2) formation of lipid layer or fatty streak within the intima, 3) migration of leukocytes and smooth muscle cells into the vessel wall, 4) foam cell formation and 5) degradation of extracellular matrix.
What is difference between arteriosclerosis and atherosclerosis?
In short, Arteriosclerosis is a disease that blocks the wall of arteries due to aging. Whereas atherosclerosis is a medical disorder that damages the lumen of the arteries by plaque deposits. Atherosclerosis is mostly a failure of controlled cholesterol and fat levels in the body.
What is the first step of atherosclerosis?
The oxidation of low density lipoprotein (LDL) to Ox-LDL indicates the first step of atherosclerosis in cardiovascular diseases. Malondialdehyde factor shows the level of lipoperoxidation and is a sign of increased oxidative pressure and cardiovascular diseases.
What is the difference between CAD and atherosclerosis?
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, or CAD.
