How does high cholesterol cause atherosclerosis?

How does high cholesterol cause atherosclerosis?

If your cholesterol is too high, it builds up on the walls of your arteries. Over time, this buildup is known as atherosclerosis. This condition causes arteries to become narrowed, and the narrowed blood vessels reduce blood flow to the heart.

What causes the development of a plaque 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.

How does cholesterol cause plaque?

Plaque forms when cholesterol lodges in the wall of the artery. To fight back, the body sends white blood cells to trap the cholesterol, which then turn into foamy cells that ooze more fat and cause more inflammation.

Can a blocked artery clear itself?

Can atherosclerosis be reversed or slowed down? The disease is progressive, and, unfortunately, current treatments can’t melt it away. However, there are things that can be done to slow its development and dramatically reduce the chances of a heart attack or stroke.

How long does the end stage of congestive heart failure last?

Most people with end-stage heart failure have a life expectancy of less than 1 year.

Does dying of heart failure hurt?

But chronic congestive heart failure brings a slower, more painful death. When the weakened heart cannot pump out all the blood inside it, the blood backs up into veins and leaks through small blood vessels; tissues swell painfully.

Can a person die suddenly from congestive heart failure?

Patients with congestive heart failure have a high incidence of sudden cardiac death that is attributed to ventricular arrhythmias. The mortality rate in a group of patients with class III and IV heart failure is about 40% per year, and half of the deaths are sudden.
