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 substance causes atherosclerosis?
Atherosclerosis thickening or hardening of the arteries. It is caused by a buildup of plaque in the inner lining of an artery. Plaque is made up of deposits of fatty substances, cholesterol, cellular waste products, calcium, and fibrin. As it builds up in the arteries, the artery walls become thickened and stiff.
What is a main contributor to the development of atherosclerosis?
Atherosclerosis is caused by repeated injury to the walls of arteries . Many factors contribute to this injury, including high blood pressure, tobacco smoke, diabetes, and high levels of cholesterol in the blood. Blood vessel blockage due to atherosclerosis is a common cause of heart attack and stroke.
What is the most important indicator that you might develop 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.
Can you live a long life with atherosclerosis?
This can lead to severe health events such as heart attack and stroke. Living healthy with atherosclerosis is possible , though, and it’s important. Plaque, which is made up of fat, cholesterol and other substances, narrows the arteries and makes blood clots more likely to form.

What is the life expectancy of someone with atherosclerosis?
Atherosclerosis represents a grave health problem, annually accounting for at least 30% of all deaths globally (Figure 51-1 ). It is associated with a poor prognosis and significantly reduces life expectancy in the 60-year-old patient by 8–12 years depending on the vascular event.
How does atherosclerosis cause death?
If the plaque in a coronary artery ruptures, it can cause a blood clot to form that prevents any blood flow and the heart muscle downstream loses all its oxygen and dies.

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.
How serious is atherosclerosis?
Over time, plaque hardens and narrows your arteries. This limits the flow of oxygen-rich blood to your organs and other parts of your body. Atherosclerosis can lead to serious problems , including heart attack, stroke, or even death.
Is atherosclerosis permanent?
Thus, early lesions of atherosclerosis are reversible and cholesterol-lowering therapy is an effective treatment; however, since advanced lesions seem to be irreversible, cholesterol-lowering therapy may not be effective for such lesions.
Can atherosclerosis be cured?
But with medication and lifestyle changes, you can slow or stop plaques . They may even shrink slightly with aggressive treatment. Lifestyle changes: You can slow or stop atherosclerosis by taking care of the risk factors. That means a healthy diet, exercise, and no smoking.
Can atherosclerosis be cured naturally?
