What happens to the arteries in 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.

What does atherosclerosis cause?

Risk factors may include high cholesterol and triglyceride levels, high blood pressure, smoking, diabetes, obesity, physical activity, and eating saturated fats. Atherosclerosis can cause a heart attack, stroke, aneurysm, or blood clot.

How does atherosclerosis cause coronary artery disease?

Coronary artery disease (CAD) is a condition which affects the arteries that supply the heart with blood. It is usually caused by atherosclerosis which is a buildup of plaque inside the artery walls. This buildup causes the inside of the arteries to become narrower and slows down the flow of blood.

What are the 4 stages of atherosclerosis?

The working theory includes four steps:

  • Endothelial cell injury. This is likely the initial factor that begins the process of atherosclerotic plaque formation.
  • Lipoprotein deposition.
  • Inflammatory reaction.
  • Smooth muscle cell cap formation.

Who does atherosclerosis affect?

Atherosclerosis can affect any artery in the body, including arteries in the heart, brain, arms, legs, pelvis, and kidneys.

Why does atherosclerosis occur in arteries and not veins?

The passage through which your blood flows becomes narrower. This causes less blood flow and higher blood pressure. Secondly, your veins and arteries become less flexible, which also affects blood flow. When this happens, it is known as a condition called atherosclerosis.

What is atherosclerosis aorta?

Having atherosclerosis (say “ath-uh-roh-skluh-ROH-sis”) of the aorta means that a material called plaque (fat and calcium) has built up in the inside wall of a large blood vessel called the aorta. This plaque buildup is sometimes called “hardening of the arteries.”

How do you detect atherosclerosis?

Doctors have an arsenal of diagnostic tests and tools they can access to confirm the presence of Atherosclerosis – these include an angiogram (Arteriogram), cholesterol tests, a chest x-ray, a CT (computed tomography) scan, Duplex scanning, an echocardiogram, an electrocardiogram (ECG or EKG), an exercise stress test ( …

What is the end stage of atherosclerosis?

The last stage of atherosclerosis occurs when the plaque breaks open, exposing the cholesterol and tissue underneath. Blood clots form in response to this rupture and cause symptoms of a heart attack and unstable angina.

What is 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 distinguishes atherosclerosis from arteriosclerosis?

Arteriosclerosis and atherosclerosis are different conditions. Arteriosclerosis is the stiffening or hardening of the artery walls. Atherosclerosis is the narrowing of the artery because of plaque build-up. Atherosclerosis is a specific type of arteriosclerosis.

What is the difference between arteriosclerosis and atherosclerosis?

Arteriosclerosis involves intimal fibrosis while atherosclerosis does not.

  • Arteriosclerosis involves tunica media thickening due to calcification while in atherosclerosis media thickens due to inflammatory mediators.
  • Arteriosclerosis may or may not narrow the lumen while atherosclerosis always does.

    • What you can do to prevent atherosclerosis?
