Atherosclerosis is a common condition that develops when a sticky substance called plaque builds up inside your arteries. Disease linked to atherosclerosis is the leading cause of death in the United States. About half of Americans between ages 45 and 84 have atherosclerosis and don’t know it. Show Atherosclerosis develops slowly as cholesterol, fat, blood cells and other substances in your blood form plaque. When the plaque builds up, it causes your arteries to narrow. This reduces the supply of oxygen-rich blood to tissues of vital organs in the body.  Atherosclerosis can affect most of the arteries in the body, including arteries in the heart, brain, arms, legs, pelvis, and kidneys. It has different names based on which arteries are affected.
Reduced blood flow can lead to symptoms such as angina. If a plaque bursts, a blood clot may form that may block the artery completely or travel to other parts of the body. Blockages, either complete or incomplete, can cause complications, including heart attack, stroke, vascular dementia, erectile dysfunction, or limb loss. Atherosclerosis can cause death and disability. Confused about terms? Plaque often starts to build up during childhood and gets worse with age. Risk factors include unhealthy cholesterol levels, unhealthy lifestyle habits, and your genes. The good news is that most people can prevent or delay the initiation and progression of atherosclerosis by following steps for heart-healthy living. Atherosclerosis, sometimes called "hardening of the arteries," occurs when fat, cholesterol, and other substances build up in the walls of arteries. These deposits are called plaques. Over time, these plaques can narrow or completely block the arteries and cause problems throughout the body. Atherosclerosis is a common disorder. Atherosclerosis often occurs with aging. As you grow older, plaque buildup narrows your arteries and makes them stiffer. These changes make it harder for blood to flow through them. Clots may form in these narrowed arteries and block blood flow. Pieces of plaque can also break off and move to smaller blood vessels, blocking them. These blockages starve tissues of blood and oxygen. This can result in damage or tissue death. It is a common cause of heart attack and stroke. High blood cholesterol levels can cause hardening of the arteries at a younger age. For many people, high cholesterol levels are due to a diet that is too high in saturated fats and trans fats. Other factors that can contribute to hardening of the arteries include:
Atherosclerosis does not cause symptoms until blood flow to part of the body becomes slowed or blocked. If the arteries supplying the heart become narrow, blood flow can slow down or stop. This can cause chest pain (stable angina), shortness of breath, and other symptoms. Narrowed or blocked arteries may also cause problems in the intestines, kidneys, legs, and brain. A health care provider will perform a physical exam and listen to the heart and lungs with a stethoscope. Atherosclerosis can create a whooshing or blowing sound ("bruit") over an artery. All adults over the age of 18 should have their blood pressure checked every year. More frequent measurement may be needed for those with a history of high blood pressure readings or those with risk factors for high blood pressure. Cholesterol testing is recommended in all adults. The major national guidelines differ on the suggested age to start testing.
A number of imaging tests may be used to see how well blood moves through your arteries.
Lifestyle changes will reduce your risk for atherosclerosis. Things you can do include:
If your blood pressure is high, it is important for you to lower it and keep it under control. The goal of treatment is to reduce your blood pressure so that you have a lower risk of health problems caused by high blood pressure. You and your provider should set a blood pressure goal for you.
Your provider may want you to take medicine for abnormal cholesterol levels or for high blood pressure if lifestyle changes do not work. This will depend on:
Your provider may suggest taking aspirin or another medicine to help prevent blood clots from forming in your arteries. These medicines are called antiplatelet drugs. DO NOT take aspirin without first talking to your provider. Losing weight if you are overweight and reducing blood sugar if you have diabetes or pre-diabetes can help reduce the risk of developing atherosclerosis. Atherosclerosis cannot be reversed once it has occurred. However, lifestyle changes and treating high cholesterol levels can prevent or slow the process from becoming worse. This can help reduce the chances of having a heart attack and stroke as a result of atherosclerosis. In some cases, the plaque is part of a process that causes a weakening of the wall of an artery. This can lead to a bulge in an artery called an aneurysm. Aneurysms can break open (rupture). This causes bleeding that can be life threatening.

Statins and other cholesterol drugs. Aggressively lowering low-density lipoprotein (LDL) cholesterol — the "bad" cholesterol — can slow, stop or even reverse the buildup of fatty deposits in the arteries. ... . Aspirin. ... . Blood pressure medications. ... . Other medications.. What is the life expectancy of someone with atherosclerosis?People with heart failure lose an average of nearly 10 years. Everyone can take steps to adopt heart-healthy living. Research shows that women who have a healthy lifestyle could expect to live 14 years longer than those who did not, while men would have 12 more years of life.
What is the main cause of hardening of the arteries?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.
How serious is hardening of the arteries?Atherosclerosis does not tend to have any symptoms at first and many people may be unaware they have it, but it can eventually cause life-threatening problems, such as heart attacks and strokes, if it gets worse.
Can you reverse hardening of arteries?Although you can't reverse atherosclerosis once it starts, you can prevent it with some easy lifestyle changes. Eat a balanced diet that's high in heart-healthy fruits, vegetables, and fish. Exercise for at least 30 to 60 minutes a day. Stop smoking, cause that's really bad news for your arteries.
