The lining or inner layer (endothelium) is usually smooth and unbroken. Atherosclerosis begins when the lining is injured or diseased. Then certain white blood cells called monocytes and T cells are activated and move out of the bloodstream and through the lining of an artery into the artery’s wall.
What layer thickens in atherosclerosis?
However, the middle layer (tunica media) is thicker in arteries than in veins.
Which layer of the arterial wall does atherosclerosis primarily affect?
Atherosclerosis, the most common type, means hardening related to plaques, which are deposits of fatty materials. It affects medium-sized and large arteries. Arteriolosclerosis means hardening of the arterioles, which are small arteries. It affects primarily the inner and middle layers of the walls of arterioles .
Which artery is usually affected by atherosclerosis?
For example: Coronary artery disease. When atherosclerosis narrows the arteries close to your heart, you may develop coronary artery disease, which can cause chest pain (angina), a heart attack or heart failure. Carotid artery disease.
In which area of an artery does atherosclerosis occur?

It can also be found in the aorta, which is the largest artery in the body. The braches of the aorta leading to the arms and legs can become lined with plaque as well.
What are the 4 stages of atherosclerosis?
- Endothelial cell injury. ...
- Lipoprotein deposition. ...
- Inflammatory reaction. ...
- Smooth muscle cell cap formation.
How fast does atherosclerosis progress?
Although atherosclerosis is believed to progress over many years, it has been increasingly noted to progress over few months to 2-3 years in few patients without traditional factors for accelerated atherosclerosis.
What are the three types of atherosclerosis?
There are three recognized types of arteriosclerosis: atherosclerosis, arteriolosclerosis , and Monckeberg medial calcific sclerosis.
What are the main causes of atherosclerosis?
Key points of atherosclerosis
Atherosclerosis is thickening or hardening of the arteries caused by a buildup of plaque in the inner lining of an artery . Risk factors may include high cholesterol and triglyceride levels, high blood pressure, smoking, diabetes, obesity, physical activity, and eating saturated fats.
What is the difference between atherosclerosis and 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 dissolves artery plaque?
HDL is like a vacuum cleaner for cholesterol in the body. When it’s at healthy levels in your blood, it removes extra cholesterol and plaque buildup in your arteries and then sends it to your liver. Your liver expels it from your body. Ultimately, this helps reduce your risk of heart disease, heart attack, and stroke.
What is the best treatment for atherosclerosis?

What are the warning signs of clogged arteries?
In addition to developing feet and leg issues, clogged arteries can cause you to experience dizzy, weak feelings , and heart palpitations. You may also sweat, feel nauseated, or have difficulty breathing.
What is the process of atherosclerosis?
Atherosclerosis, sometimes called “ hardening of the arteries ,” occurs when fat (cholesterol) and calcium build up inside the lining of the artery wall, forming a substance called plaque. Over time, the fat and calcium buildup narrows the artery and blocks blood flow through it.
