Question

Why does plaque form in blood vessels?

Answer 1

When fat (cholesterol) and calcium build up inside the lining of the artery wall, a substance called plaque forms. Atherosclerosis is also known as "hardening of the arteries." Fat and calcium buildup narrows the artery and prevents blood flow through it over time. All arteries are susceptible to atherosclerosis. There's a good probability you have atherosclerosis in other blood vessels throughout your body if you have atherosclerosis in one of your arteries.

Complete answer:
Coronary artery disease (CAD) is a condition that affects the arteries in the heart When atherosclerosis affects the coronary arteries, which feed blood to the heart, blood flow to the heart muscle is restricted.
Having a heart attack. A fibrous covering surrounds plaque caused by atherosclerosis. This fibrous cap has the potential to fracture or rupture. A rip or rupture instructs the body to mend the broken arterial lining, just how a cut on the skin is healed by generating a blood clot. A blood clot in an artery can totally cut off blood flow to the heart muscle, resulting in a heart attack.
A stroke or a transient ischemic attack (TIA) is a type of stroke. A transient ischemic attack (TIA) or stroke can occur when atherosclerosis affects the arteries that feed blood to the brain.
Peripheral arterial disease (PAD) is a condition that affects the blood vessels in the legs. Atherosclerosis can cause poor circulation by affecting arteries in other regions of the body, such as the pelvis and legs. Aortic aneurysm in the abdomen. The walls of the aorta might become weak due to atherosclerosis. The aorta is a major blood vessel that connects the heart to the rest of the body.
Plaque forms in all of the body's arteries, however not all plaques are equally hazardous. You've probably heard of the term "vulnerable plaque". A soft plaque with a thin, fibrous cap is referred to as this. This plaque is more prone to rupture, resulting in the formation of a blood clot at the rupture site, shutting off or reducing blood flow and potentially causing a heart attack or stroke.

Note:-
The elements that penetrate the artery wall from the bloodstream make up arterial plaque. Fat, cholesterol, calcium, cell waste products, and fibrin, a clotting agent, are among them. This is why your doctor will perform a cholesterol test on you. High levels of "bad cholesterol" (low-density lipoprotein, or LDL cholesterol) can suggest an increased risk of plaque formation.
